Prerequisites +---------------- + +A C compiler. Any C89 or better compiler should work. Where supported, +configure will attempt to enable the compiler's run-time integrity checking +options. Some notes about specific compilers: + - clang: -ftrapv and -sanitize=integer require the compiler-rt runtime + (CC=clang LDFLAGS=--rtlib=compiler-rt ./configure) + +To support Privilege Separation (which is now required) you will need +to create the user, group and directory used by sshd for privilege +separation. See README.privsep for details. + + +The remaining items are optional. + +A working installation of zlib: +Zlib 1.1.4 or 1.2.1.2 or greater (earlier 1.2.x versions have problems): +http://www.gzip.org/zlib/ + +libcrypto from either of LibreSSL or OpenSSL. Building without libcrypto +is supported but severely restricts the available ciphers and algorithms. + - LibreSSL (https://www.libressl.org/) + - OpenSSL (https://www.openssl.org) with any of the following versions: + - 1.0.x >= 1.0.1 or 1.1.0 >= 1.1.0g or any 1.1.1 + +Note that due to a bug in EVP_CipherInit OpenSSL 1.1 versions prior to +1.1.0g can't be used. + +LibreSSL/OpenSSL should be compiled as a position-independent library +(i.e. -fPIC, eg by configuring OpenSSL as "./config [options] -fPIC" +or LibreSSL as "CFLAGS=-fPIC ./configure") otherwise OpenSSH will not +be able to link with it. If you must use a non-position-independent +libcrypto, then you may need to configure OpenSSH --without-pie. + +If you build either from source, running the OpenSSL self-test ("make +tests") or the LibreSSL equivalent ("make check") and ensuring that all +tests pass is strongly recommended. + +NB. If you operating system supports /dev/random, you should configure +libcrypto (LibreSSL/OpenSSL) to use it. OpenSSH relies on libcrypto's +direct support of /dev/random, or failing that, either prngd or egd. + +PRNGD: + +If your system lacks kernel-based random collection, the use of Lutz +Jaenicke's PRNGd is recommended. It requires that libcrypto be configured +to support it. + +http://prngd.sourceforge.net/ + +EGD: + +The Entropy Gathering Daemon (EGD) supports the same interface as prngd. +It also supported only if libcrypto is configured to support it. + +http://egd.sourceforge.net/ + +PAM: + +OpenSSH can utilise Pluggable Authentication Modules (PAM) if your +system supports it. PAM is standard most Linux distributions, Solaris, +HP-UX 11, AIX >= 5.2, FreeBSD, NetBSD and Mac OS X. + +Information about the various PAM implementations are available: + +Solaris PAM: http://www.sun.com/software/solaris/pam/ +Linux PAM: http://www.kernel.org/pub/linux/libs/pam/ +OpenPAM: http://www.openpam.org/ + +If you wish to build the GNOME passphrase requester, you will need the GNOME +libraries and headers. + +GNOME: +http://www.gnome.org/ + +Alternatively, Jim Knoble has written an excellent X11 +passphrase requester. This is maintained separately at: + +http://www.jmknoble.net/software/x11-ssh-askpass/ + +LibEdit: + +sftp supports command-line editing via NetBSD's libedit. If your platform +has it available natively you can use that, alternatively you might try +these multi-platform ports: + +http://www.thrysoee.dk/editline/ +http://sourceforge.net/projects/libedit/ + +LDNS: + +LDNS is a DNS BSD-licensed resolver library which supports DNSSEC. + +http://nlnetlabs.nl/projects/ldns/ + +Autoconf: + +If you modify configure.ac or configure doesn't exist (eg if you checked +the code out of git yourself) then you will need autoconf-2.69 and +automake-1.16.1 to rebuild the automatically generated files by running +"autoreconf". Earlier versions may also work but this is not guaranteed. + +http://www.gnu.org/software/autoconf/ +http://www.gnu.org/software/automake/ + +Basic Security Module (BSM): + +Native BSM support is known to exist in Solaris from at least 2.5.1, +FreeBSD 6.1 and OS X. Alternatively, you may use the OpenBSM +implementation (http://www.openbsm.org). + +makedepend: + +https://www.x.org/archive/individual/util/ + +If you are making significant changes to the code you may need to rebuild +the dependency (.depend) file using "make depend", which requires the +"makedepend" tool from the X11 distribution. + +libfido2: + +libfido2 allows the use of hardware security keys over USB. libfido2 +in turn depends on libcbor. libfido2 >= 1.5.0 is strongly recommended. +Limited functionality is possible with earlier libfido2 versions. + +https://github.com/Yubico/libfido2 +https://github.com/pjk/libcbor + + +2. Building / Installation +-------------------------- + +To install OpenSSH with default options: + +./configure +make +make install + +This will install the OpenSSH binaries in /usr/local/bin, configuration files +in /usr/local/etc, the server in /usr/local/sbin, etc. To specify a different +installation prefix, use the --prefix option to configure: + +./configure --prefix=/opt +make +make install + +Will install OpenSSH in /opt/{bin,etc,lib,sbin}. You can also override +specific paths, for example: + +./configure --prefix=/opt --sysconfdir=/etc/ssh +make +make install + +This will install the binaries in /opt/{bin,lib,sbin}, but will place the +configuration files in /etc/ssh. + +If you are using PAM, you may need to manually install a PAM control +file as "/etc/pam.d/sshd" (or wherever your system prefers to keep +them). Note that the service name used to start PAM is __progname, +which is the basename of the path of your sshd (e.g., the service name +for /usr/sbin/osshd will be osshd). If you have renamed your sshd +executable, your PAM configuration may need to be modified. + +A generic PAM configuration is included as "contrib/sshd.pam.generic", +you may need to edit it before using it on your system. If you are +using a recent version of Red Hat Linux, the config file in +contrib/redhat/sshd.pam should be more useful. Failure to install a +valid PAM file may result in an inability to use password +authentication. On HP-UX 11 and Solaris, the standard /etc/pam.conf +configuration will work with sshd (sshd will match the other service +name). + +There are a few other options to the configure script: + +--with-audit=[module] enable additional auditing via the specified module. +Currently, drivers for "debug" (additional info via syslog) and "bsm" +(Sun's Basic Security Module) are supported. + +--with-pam enables PAM support. If PAM support is compiled in, it must +also be enabled in sshd_config (refer to the UsePAM directive). + +--with-prngd-socket=/some/file allows you to enable EGD or PRNGD +support and to specify a PRNGd socket. Use this if your Unix lacks +/dev/random. + +--with-prngd-port=portnum allows you to enable EGD or PRNGD support +and to specify a EGD localhost TCP port. Use this if your Unix lacks +/dev/random. + +--with-lastlog=FILE will specify the location of the lastlog file. +./configure searches a few locations for lastlog, but may not find +it if lastlog is installed in a different place. + +--without-lastlog will disable lastlog support entirely. + +--with-osfsia, --without-osfsia will enable or disable OSF1's Security +Integration Architecture. The default for OSF1 machines is enable. + +--with-utmpx enables utmpx support. utmpx support is automatic for +some platforms. + +--without-shadow disables shadow password support. + +--with-ipaddr-display forces the use of a numeric IP address in the +$DISPLAY environment variable. Some broken systems need this. + +--with-default-path=PATH allows you to specify a default $PATH for sessions +started by sshd. This replaces the standard path entirely. + +--with-pid-dir=PATH specifies the directory in which the sshd.pid file is +created. + +--with-xauth=PATH specifies the location of the xauth binary + +--with-ssl-dir=DIR allows you to specify where your Libre/OpenSSL +libraries are installed. + +--with-ssl-engine enables Libre/OpenSSL's (hardware) ENGINE support + +--without-openssl builds without using OpenSSL. Only a subset of ciphers +and algorithms are supported in this configuration. + +--without-zlib builds without zlib. This disables the Compression option. + +--with-4in6 Check for IPv4 in IPv6 mapped addresses and convert them to +real (AF_INET) IPv4 addresses. Works around some quirks on Linux. + +If you need to pass special options to the compiler or linker, you +can specify these as environment variables before running ./configure. +For example: + +CC="/usr/foo/cc" CFLAGS="-O" LDFLAGS="-s" LIBS="-lrubbish" ./configure + +3. Configuration +---------------- + +The runtime configuration files are installed by in ${prefix}/etc or +whatever you specified as your --sysconfdir (/usr/local/etc by default). + +The default configuration should be instantly usable, though you should +review it to ensure that it matches your security requirements. + +To generate a host key, run "make host-key". Alternately you can do so +manually using the following commands: + + ssh-keygen -t [type] -f /etc/ssh/ssh_host_key -N "" + +for each of the types you wish to generate (rsa, dsa or ecdsa) or + + ssh-keygen -A + +to generate keys for all supported types. + +Replacing /etc/ssh with the correct path to the configuration directory. +(${prefix}/etc or whatever you specified with --sysconfdir during +configuration). + +If you have configured OpenSSH with EGD/prngd support, ensure that EGD or +prngd is running and has collected some entropy first. + +For more information on configuration, please refer to the manual pages +for sshd, ssh and ssh-agent. + +4. (Optional) Send survey +------------------------- + +$ make survey +[check the contents of the file "survey" to ensure there's no information +that you consider sensitive] +$ make send-survey + +This will send configuration information for the currently configured +host to a survey address. This will help determine which configurations +are actually in use, and what valid combinations of configure options +exist. The raw data is available only to the OpenSSH developers, however +summary data may be published. + +5.

The main program for each of these is in a .c +file with the same name. + +There are some subsystems/abstractions that are used by a number of +these programs. + + Buffer manipulation routines + + - These provide an arbitrary size buffer, where data can be appended. + Data can be consumed from either end. The code is used heavily + throughout ssh. The buffer manipulation functions are in + sshbuf*.c (header sshbuf.h). + + Compression Library + + - Ssh uses the GNU GZIP compression library (ZLIB). + + Encryption/Decryption + + - Ssh contains several encryption algorithms. These are all + accessed through the cipher.h interface. The interface code is + in cipher.c, and the implementations are either in libc or + LibreSSL. + + Multiple Precision Integer Library + + - Uses the LibreSSL BIGNUM sublibrary. + + Random Numbers + + - Uses arc4random() and such. + + RSA key generation, encryption, decryption + + - Ssh uses the RSA routines in libssl. + + RSA key files + + - RSA keys are stored in files with a special format. The code to + read/write these files is in authfile.c. The files are normally + encrypted with a passphrase. The functions to read passphrases + are in readpass.c (the same code is used to read passwords). + + Binary packet protocol + + - The ssh binary packet protocol is implemented in packet.c. The + code in packet.c does not concern itself with packet types or their + execution; it contains code to build packets, to receive them and + extract data from them, and the code to compress and/or encrypt + packets. + + - The code in packet.c calls the buffer manipulation routines + (buffer.c, bufaux.c), compression routines (zlib), and the + encryption routines. + + X11, TCP/IP, and Agent forwarding + + - Code for various types of channel forwarding is in channels.c. + The file defines a generic framework for arbitrary communication + channels inside the secure channel, and uses this framework to + implement X11 forwarding, TCP/IP forwarding, and authentication + agent forwarding. + The new, Protocol 1.5, channel close implementation is in nchan.c + + Authentication agent + + - Code to communicate with the authentication agent is in authfd.c. + + Authentication methods + + - Code for various authentication methods resides in auth-*.c + (auth-passwd.c, auth-rh-rsa.c, auth-rhosts.c, auth-rsa.c). This + code is linked into the server. The routines also manipulate + known hosts files using code in hostfile.c. Code in canohost.c + is used to retrieve the canonical host name of the remote host. + Code in match.c is used to match host names. + + - In the client end, authentication code is in sshconnect.c. It + reads Passwords/passphrases using code in readpass.c. It reads + RSA key files with authfile.c. It communicates the + authentication agent using authfd.c. + + The ssh client + + - The client main program is in ssh.c. It first parses arguments + and reads configuration (readconf.c), then calls ssh_connect (in + sshconnect.c) to open a connection to the server (possibly via a + proxy), and performs authentication (ssh_login in sshconnect.c). + It then makes any pty, forwarding, etc. requests. It may call + code in ttymodes.c to encode current tty modes. Finally it + calls client_loop in clientloop.c. This does the real work for + the session. + + Pseudo-tty manipulation and tty modes + + - Code to allocate and use a pseudo tty is in pty.c. Code to + encode and set terminal modes is in ttymodes.c. + + Logging in (updating utmp, lastlog, etc.) + + - The code to do things that are done when a user logs in are in + login.c. This includes things such as updating the utmp, wtmp, + and lastlog files. Some of the code is in sshd.c. + + Writing to the system log and terminal + + - The programs use the functions fatal(), log(), debug(), error() + in many places to write messages to system log or user's + terminal. The implementation that logs to system log is in + log-server.c; it is used in the server program. The other + programs use an implementation that sends output to stderr; it + is in log-client.c. The definitions are in ssh.h. + + The sshd server (daemon) + + - The sshd daemon starts by processing arguments and reading the + configuration file (servconf.c). It then reads the host key, + starts listening for connections, and generates the server key. + The server key will be regenerated every hour by an alarm. + + - When the server receives a connection, it forks, disables the + regeneration alarm, and starts communicating with the client. + They first perform identification string exchange, then + negotiate encryption, then perform authentication, preparatory + operations, and finally the server enters the normal session + mode by calling server_loop in serverloop.c. This does the real + work, calling functions in other modules. + + - The code for the server is in sshd.c. It contains a lot of + stuff, including: + - server main program + - waiting for connections + - processing new connection + - authentication + - preparatory operations + - building up the execution environment for the user program + - starting the user program. + + Auxiliary files + + - There are several other files in the distribution that contain + various auxiliary routines: + ssh.h the main header file for ssh (various definitions) + uidswap.c uid-swapping + xmalloc.c "safe" malloc routines + +$OpenBSD: OVERVIEW,v 1.15 2018/10/23 05:56:35 djm Exp $ diff --git a/aosp/external/openssh/OWNERS b/aosp/external/openssh/OWNERS new file mode 100644 index 0000000000000000000000000000000000000000..f3c79ccc4fa73a1a0378076625f5b9196183cda7 --- /dev/null +++ b/aosp/external/openssh/OWNERS @@ -0,0 +1,3 @@ +# Default code reviewers picked from top 3 or more developers. +# Please update this list if you find better candidates. +adelva@google.com diff --git a/aosp/external/openssh/PROTOCOL b/aosp/external/openssh/PROTOCOL new file mode 100644 index 0000000000000000000000000000000000000000..2d50b5cb0528d550f9acdc83ea16e8cfa3604259 --- /dev/null +++ b/aosp/external/openssh/PROTOCOL @@ -0,0 +1,652 @@ +This documents OpenSSH's deviations and extensions to the published SSH +protocol. + +Note that OpenSSH's sftp and sftp-server implement revision 3 of the SSH +filexfer protocol described in: + +https://www.openssh.com/txt/draft-ietf-secsh-filexfer-02.txt + +Newer versions of the draft will not be supported, though some features +are individually implemented as extensions described below. + +The protocol used by OpenSSH's ssh-agent is described in the file +PROTOCOL.agent + +1. Transport protocol changes + +1.1. transport: Protocol 2 MAC algorithm "umac-64@openssh.com" + +This is a new transport-layer MAC method using the UMAC algorithm +(rfc4418).

This +avoids exposing compression code to attacks from unauthenticated users. + +The method is documented in: + +https://www.openssh.com/txt/draft-miller-secsh-compression-delayed-00.txt + +1.3. transport: New public key algorithms "ssh-rsa-cert-v01@openssh.com", + "ssh-dsa-cert-v01@openssh.com", + "ecdsa-sha2-nistp256-cert-v01@openssh.com", + "ecdsa-sha2-nistp384-cert-v01@openssh.com" and + "ecdsa-sha2-nistp521-cert-v01@openssh.com" + +OpenSSH introduces new public key algorithms to support certificate +authentication for users and host keys. These methods are documented +in the file PROTOCOL.certkeys + +1.4. transport: Elliptic Curve cryptography + +OpenSSH supports ECC key exchange and public key authentication as +specified in RFC5656. Only the ecdsa-sha2-nistp256, ecdsa-sha2-nistp384 +and ecdsa-sha2-nistp521 curves over GF(p) are supported. Elliptic +curve points encoded using point compression are NOT accepted or +generated. + +1.5 transport: Protocol 2 Encrypt-then-MAC MAC algorithms + +OpenSSH supports MAC algorithms, whose names contain "-etm", that +perform the calculations in a different order to that defined in RFC +4253. These variants use the so-called "encrypt then MAC" ordering, +calculating the MAC over the packet ciphertext rather than the +plaintext. This ordering closes a security flaw in the SSH transport +protocol, where decryption of unauthenticated ciphertext provided a +"decryption oracle" that could, in conjunction with cipher flaws, reveal +session plaintext. + +Specifically, the "-etm" MAC algorithms modify the transport protocol +to calculate the MAC over the packet ciphertext and to send the packet +length unencrypted. This is necessary for the transport to obtain the +length of the packet and location of the MAC tag so that it may be +verified without decrypting unauthenticated data. + +As such, the MAC covers: + + mac = MAC(key, sequence_number || packet_length || encrypted_packet) + +where "packet_length" is encoded as a uint32 and "encrypted_packet" +contains: + + byte padding_length + byte[n1] payload; n1 = packet_length - padding_length - 1 + byte[n2] random padding; n2 = padding_length + +1.6 transport: AES-GCM + +OpenSSH supports the AES-GCM algorithm as specified in RFC 5647. +Because of problems with the specification of the key exchange +the behaviour of OpenSSH differs from the RFC as follows: + +AES-GCM is only negotiated as the cipher algorithms +"aes128-gcm@openssh.com" or "aes256-gcm@openssh.com" and never as +an MAC algorithm. Additionally, if AES-GCM is selected as the cipher +the exchanged MAC algorithms are ignored and there doesn't have to be +a matching MAC. + +1.7 transport: chacha20-poly1305@openssh.com authenticated encryption + +OpenSSH supports authenticated encryption using ChaCha20 and Poly1305 +as described in PROTOCOL.chacha20poly1305. + +1.8 transport: curve25519-sha256@libssh.org key exchange algorithm + +OpenSSH supports the use of ECDH in Curve25519 for key exchange as +described at: +http://git.libssh.org/users/aris/libssh.git/plain/doc/curve25519-sha256@libssh.org.txt?h=curve25519 + +2. Connection protocol changes + +2.1. connection: Channel write close extension "eow@openssh.com" + +The SSH connection protocol (rfc4254) provides the SSH_MSG_CHANNEL_EOF +message to allow an endpoint to signal its peer that it will send no +more data over a channel. Unfortunately, there is no symmetric way for +an endpoint to request that its peer should cease sending data to it +while still keeping the channel open for the endpoint to send data to +the peer. + +This is desirable, since it saves the transmission of data that would +otherwise need to be discarded and it allows an endpoint to signal local +processes of the condition, e.g. by closing the corresponding file +descriptor. + +OpenSSH implements a channel extension message to perform this +signalling: "eow@openssh.com" (End Of Write). This message is sent by +an endpoint when the local output of a session channel is closed or +experiences a write error. The message is formatted as follows: + + byte SSH_MSG_CHANNEL_REQUEST + uint32 recipient channel + string "eow@openssh.com" + boolean FALSE + +On receiving this message, the peer SHOULD cease sending data of +the channel and MAY signal the process from which the channel data +originates (e.g. by closing its read file descriptor). + +As with the symmetric SSH_MSG_CHANNEL_EOF message, the channel does +remain open after a "eow@openssh.com" has been sent and more data may +still be sent in the other direction. This message does not consume +window space and may be sent even if no window space is available. + +NB. due to certain broken SSH implementations aborting upon receipt +of this message (in contravention of RFC4254 section 5.4), this +message is only sent to OpenSSH peers (identified by banner). +Other SSH implementations may be listed to receive this message +upon request. + +2.2. connection: disallow additional sessions extension + "no-more-sessions@openssh.com" + +Most SSH connections will only ever request a single session, but a +attacker may abuse a running ssh client to surreptitiously open +additional sessions under their control. OpenSSH provides a global +request "no-more-sessions@openssh.com" to mitigate this attack. + +When an OpenSSH client expects that it will never open another session +(i.e. it has been started with connection multiplexing disabled), it +will send the following global request: + + byte SSH_MSG_GLOBAL_REQUEST + string "no-more-sessions@openssh.com" + char want-reply + +On receipt of such a message, an OpenSSH server will refuse to open +future channels of type "session" and instead immediately abort the +connection. + +Note that this is not a general defence against compromised clients +(that is impossible), but it thwarts a simple attack. + +NB. due to certain broken SSH implementations aborting upon receipt +of this message, the no-more-sessions request is only sent to OpenSSH +servers (identified by banner). Other SSH implementations may be +listed to receive this message upon request. + +2.3. connection: Tunnel forward extension "tun@openssh.com" + +OpenSSH supports layer 2 and layer 3 tunnelling via the "tun@openssh.com" +channel type. This channel type supports forwarding of network packets +with datagram boundaries intact between endpoints equipped with +interfaces like the BSD tun(4) device. Tunnel forwarding channels are +requested by the client with the following packet: + + byte SSH_MSG_CHANNEL_OPEN + string "tun@openssh.com" + uint32 sender channel + uint32 initial window size + uint32 maximum packet size + uint32 tunnel mode + uint32 remote unit number + +The "tunnel mode" parameter specifies whether the tunnel should forward +layer 2 frames or layer 3 packets. It may take one of the following values: + + SSH_TUNMODE_POINTOPOINT 1 /* layer 3 packets */ + SSH_TUNMODE_ETHERNET 2 /* layer 2 frames */ + +The "tunnel unit number" specifies the remote interface number, or may +be 0x7fffffff to allow the server to automatically choose an interface. A +server that is not willing to open a client-specified unit should refuse +the request with a SSH_MSG_CHANNEL_OPEN_FAILURE error. On successful +open, the server should reply with SSH_MSG_CHANNEL_OPEN_SUCCESS. + +Once established the client and server may exchange packet or frames +over the tunnel channel by encapsulating them in SSH protocol strings +and sending them as channel data. This ensures that packet boundaries +are kept intact. Specifically, packets are transmitted using normal +SSH_MSG_CHANNEL_DATA packets: + + byte SSH_MSG_CHANNEL_DATA + uint32 recipient channel + string data + +The contents of the "data" field for layer 3 packets is: + + uint32 packet length + uint32 address family + byte[packet length - 4] packet data + +The "address family" field identifies the type of packet in the message. +It may be one of: + + SSH_TUN_AF_INET 2 /* IPv4 */ + SSH_TUN_AF_INET6 24 /* IPv6 */ + +The "packet data" field consists of the IPv4/IPv6 datagram itself +without any link layer header. + +The contents of the "data" field for layer 2 packets is: + + uint32 packet length + byte[packet length] frame + +The "frame" field contains an IEEE 802.3 Ethernet frame, including +header. + +2.4. connection: Unix domain socket forwarding + +OpenSSH supports local and remote Unix domain socket forwarding +using the "streamlocal" extension. Forwarding is initiated as per +TCP sockets but with a single path instead of a host and port. + +Similar to direct-tcpip, direct-streamlocal is sent by the client +to request that the server make a connection to a Unix domain socket. + + byte SSH_MSG_CHANNEL_OPEN + string "direct-streamlocal@openssh.com" + uint32 sender channel + uint32 initial window size + uint32 maximum packet size + string socket path + string reserved + uint32 reserved + +Similar to forwarded-tcpip, forwarded-streamlocal is sent by the +server when the client has previously send the server a streamlocal-forward +GLOBAL_REQUEST. + + byte SSH_MSG_CHANNEL_OPEN + string "forwarded-streamlocal@openssh.com" + uint32 sender channel + uint32 initial window size + uint32 maximum packet size + string socket path + string reserved for future use + +The reserved field is not currently defined and is ignored on the +remote end. It is intended to be used in the future to pass +information about the socket file, such as ownership and mode. +The client currently sends the empty string for this field. + +Similar to tcpip-forward, streamlocal-forward is sent by the client +to request remote forwarding of a Unix domain socket. + + byte SSH2_MSG_GLOBAL_REQUEST + string "streamlocal-forward@openssh.com" + boolean TRUE + string socket path + +Similar to cancel-tcpip-forward, cancel-streamlocal-forward is sent +by the client cancel the forwarding of a Unix domain socket. + + byte SSH2_MSG_GLOBAL_REQUEST + string "cancel-streamlocal-forward@openssh.com" + boolean FALSE + string socket path + +2.5. connection: hostkey update and rotation "hostkeys-00@openssh.com" +and "hostkeys-prove-00@openssh.com" + +OpenSSH supports a protocol extension allowing a server to inform +a client of all its protocol v.2 host keys after user-authentication +has completed. + + byte SSH_MSG_GLOBAL_REQUEST + string "hostkeys-00@openssh.com" + char 0 /* want-reply */ + string[] hostkeys + +Upon receiving this message, a client should check which of the +supplied host keys are present in known_hosts. + +Note that the server may send key types that the client does not +support. The client should disregard such keys if they are received. + +If the client identifies any keys that are not present for the host, +it should send a "hostkeys-prove@openssh.com" message to request the +server prove ownership of the private half of the key. + + byte SSH_MSG_GLOBAL_REQUEST + string "hostkeys-prove-00@openssh.com" + char 1 /* want-reply */ + string[] hostkeys + +When a server receives this message, it should generate a signature +using each requested key over the following: + + string "hostkeys-prove-00@openssh.com" + string session identifier + string hostkey + +These signatures should be included in the reply, in the order matching +the hostkeys in the request: + + byte SSH_MSG_REQUEST_SUCCESS + string[] signatures + +When the client receives this reply (and not a failure), it should +validate the signatures and may update its known_hosts file, adding keys +that it has not seen before and deleting keys for the server host that +are no longer offered. + +These extensions let a client learn key types that it had not previously +encountered, thereby allowing it to potentially upgrade from weaker +key algorithms to better ones. It also supports graceful key rotation: +a server may offer multiple keys of the same type for a period (to +give clients an opportunity to learn them using this extension) before +removing the deprecated key from those offered. + +2.6. connection: SIGINFO support for "signal" channel request + +The SSH channels protocol (RFC4254 section 6.9) supports sending a +signal to a session attached to a channel. OpenSSH supports one +extension signal "INFO@openssh.com" that allows sending SIGINFO on +BSD-derived systems. + +3. Authentication protocol changes + +3.1. Host-bound public key authentication + +This is trivial change to the traditional "publickey" authentication +method. The authentication request is identical to the original method +but for the name and one additional field: + + byte SSH2_MSG_USERAUTH_REQUEST + string username + string "ssh-connection" + string "publickey-hostbound-v00@openssh.com" + bool has_signature + string pkalg + string public key + string server host key + +Because the entire SSH2_MSG_USERAUTH_REQUEST message is included in +the signed data, this ensures that a binding between the destination +user, the server identity and the session identifier is visible to the +signer. OpenSSH uses this binding via signed data to implement per-key +restrictions in ssh-agent. + +A server may advertise this method using the SSH2_MSG_EXT_INFO +mechanism (RFC8308), with the following message: + + string "publickey-hostbound@openssh.com" + string "0" (version) + +Clients should prefer host-bound authentication when advertised by +server. + +4. SFTP protocol changes + +4.1. sftp: Reversal of arguments to SSH_FXP_SYMLINK + +When OpenSSH's sftp-server was implemented, the order of the arguments +to the SSH_FXP_SYMLINK method was inadvertently reversed. Unfortunately, +the reversal was not noticed until the server was widely deployed. Since +fixing this to follow the specification would cause incompatibility, the +current order was retained. For correct operation, clients should send +SSH_FXP_SYMLINK as follows: + + uint32 id + string targetpath + string linkpath + +4.2. sftp: Server extension announcement in SSH_FXP_VERSION + +OpenSSH's sftp-server lists the extensions it supports using the +standard extension announcement mechanism in the SSH_FXP_VERSION server +hello packet: + + uint32 3 /* protocol version */ + string ext1-name + string ext1-version + string ext2-name + string ext2-version + ... + string extN-name + string extN-version + +Each extension reports its integer version number as an ASCII encoded +string, e.g. "1". The version will be incremented if the extension is +ever changed in an incompatible way. The server MAY advertise the same +extension with multiple versions (though this is unlikely).

This approach has some benefits +relating to simplicity of configuration and minimisation of attack +surface, but it does not support the important use-cases of centrally +managed, passwordless authentication and centrally certified host keys. + +These protocol extensions build on the simple public key authentication +system already in SSH to allow certificate-based authentication. The +certificates used are not traditional X.509 certificates, with numerous +options and complex encoding rules, but something rather more minimal: a +key, some identity information and usage options that have been signed +with some other trusted key. + +A sshd server may be configured to allow authentication via certified +keys, by extending the existing ~/.ssh/authorized_keys mechanism to +allow specification of certification authority keys in addition to +raw user keys. The ssh client will support automatic verification of +acceptance of certified host keys, by adding a similar ability to +specify CA keys in ~/.ssh/known_hosts. + +All certificate types include certification information along with the +public key that is used to sign challenges.

It operates by permuting 128 fixed bits, 128 or 256 bits of key, +a 64 bit nonce and a 64 bit counter into 64 bytes of output. This output +is used as a keystream, with any unused bytes simply discarded. + +Poly1305[2], also by Daniel Bernstein, is a one-time Carter-Wegman MAC +that computes a 128 bit integrity tag given a message and a single-use +256 bit secret key. + +The chacha20-poly1305@openssh.com combines these two primitives into an +authenticated encryption mode. The construction used is based on that +proposed for TLS by Adam Langley in [3], but differs in the layout of +data passed to the MAC and in the addition of encryption of the packet +lengths. + +Negotiation +----------- + +The chacha20-poly1305@openssh.com offers both encryption and +authentication. As such, no separate MAC is required. If the +chacha20-poly1305@openssh.com cipher is selected in key exchange, +the offered MAC algorithms are ignored and no MAC is required to be +negotiated. + +Detailed Construction +--------------------- + +The chacha20-poly1305@openssh.com cipher requires 512 bits of key +material as output from the SSH key exchange. This forms two 256 bit +keys (K_1 and K_2), used by two separate instances of chacha20. +The first 256 bits constitute K_2 and the second 256 bits become +K_1. + +The instance keyed by K_1 is a stream cipher that is used only +to encrypt the 4 byte packet length field. The second instance, +keyed by K_2, is used in conjunction with poly1305 to build an AEAD +(Authenticated Encryption with Associated Data) that is used to encrypt +and authenticate the entire packet. + +Two separate cipher instances are used here so as to keep the packet +lengths confidential but not create an oracle for the packet payload +cipher by decrypting and using the packet length prior to checking +the MAC. By using an independently-keyed cipher instance to encrypt the +length, an active attacker seeking to exploit the packet input handling +as a decryption oracle can learn nothing about the payload contents or +its MAC (assuming key derivation, ChaCha20 and Poly1305 are secure). + +The AEAD is constructed as follows: for each packet, generate a Poly1305 +key by taking the first 256 bits of ChaCha20 stream output generated +using K_2, an IV consisting of the packet sequence number encoded as an +uint64 under the SSH wire encoding rules and a ChaCha20 block counter of +zero. The K_2 ChaCha20 block counter is then set to the little-endian +encoding of 1 (i.e. {1, 0, 0, 0, 0, 0, 0, 0}) and this instance is used +for encryption of the packet payload. + +Packet Handling +--------------- + +When receiving a packet, the length must be decrypted first. When 4 +bytes of ciphertext length have been received, they may be decrypted +using the K_1 key, a nonce consisting of the packet sequence number +encoded as a uint64 under the usual SSH wire encoding and a zero block +counter to obtain the plaintext length. + +Once the entire packet has been received, the MAC MUST be checked +before decryption. A per-packet Poly1305 key is generated as described +above and the MAC tag calculated using Poly1305 with this key over the +ciphertext of the packet length and the payload together. The calculated +MAC is then compared in constant time with the one appended to the +packet and the packet decrypted using ChaCha20 as described above (with +K_2, the packet sequence number as nonce and a starting block counter of +1). + +To send a packet, first encode the 4 byte length and encrypt it using +K_1. Encrypt the packet payload (using K_2) and append it to the +encrypted length. Finally, calculate a MAC tag and append it. + +Rekeying +-------- + +ChaCha20 must never reuse a {key, nonce} for encryption nor may it be +used to encrypt more than 2^70 bytes under the same {key, nonce}. The +SSH Transport protocol (RFC4253) recommends a far more conservative +rekeying every 1GB of data sent or received. If this recommendation +is followed, then chacha20-poly1305@openssh.com requires no special +handling in this area. + +References +---------- + +[1] "ChaCha, a variant of Salsa20", Daniel Bernstein + http://cr.yp.to/chacha/chacha-20080128.pdf + +[2] "The Poly1305-AES message-authentication code", Daniel Bernstein + http://cr.yp.to/mac/poly1305-20050329.pdf + +[3] "ChaCha20 and Poly1305 based Cipher Suites for TLS", Adam Langley + http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03 + +$OpenBSD: PROTOCOL.chacha20poly1305,v 1.5 2020/02/21 00:04:43 dtucker Exp $ + diff --git a/aosp/external/openssh/PROTOCOL.key b/aosp/external/openssh/PROTOCOL.key new file mode 100644 index 0000000000000000000000000000000000000000..38df268b6536f1d0e245d07f704953abf6242d90 --- /dev/null +++ b/aosp/external/openssh/PROTOCOL.key @@ -0,0 +1,71 @@ +This document describes the private key format for OpenSSH. + +1.

U2F tokens are ubiquitous, +available from a number of manufacturers and are currently by far the +cheapest way for users to achieve hardware-backed credential storage. + +The U2F protocol however cannot be trivially used as an SSH protocol key +type as both the inputs to the signature operation and the resultant +signature differ from those specified for SSH. For similar reasons, +integration of U2F devices cannot be achieved via the PKCS#11 API. + +U2F also offers a number of features that are attractive in the context +of SSH authentication. They can be configured to require indication +of "user presence" for each signature operation (typically achieved +by requiring the user touch the key). They also offer an attestation +mechanism at key enrollment time that can be used to prove that a +given key is backed by hardware. Finally the signature format includes +a monotonic signature counter that can be used (at scale) to detect +concurrent use of a private key, should it be extracted from hardware. + +U2F private keys are generated through an enrollment operation, +which takes an application ID - a URL-like string, typically "ssh:" +in this case, but a HTTP origin for the case of web authentication, +and a challenge string (typically randomly generated). The enrollment +operation returns a public key, a key handle that must be used to invoke +the hardware-backed private key, some flags and signed attestation +information that may be used to verify that a private key is hosted on a +particular hardware instance. + +It is common for U2F hardware to derive private keys from the key handle +in conjunction with a small per-device secret that is unique to the +hardware, thus requiring little on-device storage for an effectively +unlimited number of supported keys. This drives the requirement that +the key handle be supplied for each signature operation. U2F tokens +primarily use ECDSA signatures in the NIST-P256 field, though the FIDO2 +standard specifies additional key types, including one based on Ed25519. + +Use of U2F security keys does not automatically imply multi-factor +authentication. From sshd's perspective, a security key constitutes a +single factor of authentication, even if protected by a PIN or biometric +authentication. To enable multi-factor authentication in ssh, please +refer to the AuthenticationMethods option in sshd_config(5). + + +SSH U2F Key formats +------------------- + +OpenSSH integrates U2F as new key and corresponding certificate types: + + sk-ecdsa-sha2-nistp256@openssh.com + sk-ecdsa-sha2-nistp256-cert-v01@openssh.com + sk-ssh-ed25519@openssh.com + sk-ssh-ed25519-cert-v01@openssh.com + +While each uses ecdsa-sha256-nistp256 as the underlying signature primitive, +keys require extra information in the public and private keys, and in +the signature object itself.

This standard builds upon the +FIDO standards, but requires different signature contents to raw FIDO +messages. OpenSSH supports ECDSA/p256 webauthn signatures through the +"webauthn-sk-ecdsa-sha2-nistp256@openssh.com" signature algorithm. + +The wire encoding for a webauthn-sk-ecdsa-sha2-nistp256@openssh.com +signature is similar to the sk-ecdsa-sha2-nistp256@openssh.com format: + + string "webauthn-sk-ecdsa-sha2-nistp256@openssh.com" + string ecdsa_signature + byte flags + uint32 counter + string origin + string clientData + string extensions + +Where "origin" is the HTTP origin making the signature, "clientData" is +the JSON-like structure signed by the browser and "extensions" are any +extensions used in making the signature. + +[1] https://www.w3.org/TR/webauthn-2/ + +ssh-agent protocol extensions +----------------------------- + +ssh-agent requires a protocol extension to support U2F keys. At +present the closest analogue to Security Keys in ssh-agent are PKCS#11 +tokens, insofar as they require a middleware library to communicate with +the device that holds the keys. Unfortunately, the protocol message used +to add PKCS#11 keys to ssh-agent does not include any way to send the +key handle to the agent as U2F keys require. + +To avoid this, without having to add wholly new messages to the agent +protocol, we will use the existing SSH2_AGENTC_ADD_ID_CONSTRAINED message +with a new key constraint extension to encode a path to the middleware +library for the key. The format of this constraint extension would be: + + byte SSH_AGENT_CONSTRAIN_EXTENSION + string sk-provider@openssh.com + string middleware path + +This constraint-based approach does not present any compatibility +problems. + +OpenSSH integration +------------------- + +U2F tokens may be attached via a number of means, including USB and NFC. +The USB interface is standardised around a HID protocol, but we want to +be able to support other transports as well as dummy implementations for +regress testing. For this reason, OpenSSH shall support a dynamically- +loaded middleware libraries to communicate with security keys, but offer +support for the common case of USB HID security keys internally. + +The middleware library need only expose a handful of functions and +numbers listed in sk-api.h. Included in the defined numbers is a +SSH_SK_VERSION_MAJOR that should be incremented for each incompatible +API change. + +miscellaneous options may be passed to the middleware as a NULL- +terminated array of pointers to struct sk_option. The middleware may +ignore unsupported or unknown options unless the "required" flag is set, +in which case it should return failure if an unsupported option is +requested. + +At present the following options names are supported: + + "device" + + Specifies a specific FIDO device on which to perform the + operation. The value in this field is interpreted by the + middleware but it would be typical to specify a path to + a /dev node for the device in question. + + "user" + + Specifies the FIDO2 username used when enrolling a key, + overriding OpenSSH's default of using an all-zero username. + +In OpenSSH, the middleware will be invoked by using a similar mechanism to +ssh-pkcs11-helper to provide address-space containment of the +middleware from ssh-agent. + +$OpenBSD: PROTOCOL.u2f,v 1.26 2020/09/09 03:08:01 djm Exp $ diff --git a/aosp/external/openssh/README b/aosp/external/openssh/README new file mode 100644 index 0000000000000000000000000000000000000000..70a8f814caa9c3d95bdc4afcf276260cbb831208 --- /dev/null +++ b/aosp/external/openssh/README @@ -0,0 +1,52 @@ +See https://www.openssh.com/releasenotes.html#9.0p1 for the release notes. + +Please read https://www.openssh.com/report.html for bug reporting +instructions and note that we do not use Github for bug reporting or +patch/pull-request management. + +This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other +Unices. + +OpenSSH is based on the last free version of Tatu Ylonen's sample +implementation with all patent-encumbered algorithms removed (to +external libraries), all known security bugs fixed, new features +reintroduced and many other clean-ups.

Cygwin specific stuff concerning OpenSSH. + +The binary package is usually built for recent Cygwin versions and might +not run on older versions. Please check http://cygwin.com/ for information +about current Cygwin releases. + +================== +Host configuration +================== + +If you are installing OpenSSH the first time, you can generate global config +files and server keys, as well as installing sshd as a service, by running + + /usr/bin/ssh-host-config + +Note that this binary archive doesn't contain default config files in /etc. +That files are only created if ssh-host-config is started. + +To support testing and unattended installation ssh-host-config got +some options: + +usage: ssh-host-config [OPTION]... +Options: + --debug -d Enable shell's debug output. + --yes -y Answer all questions with "yes" automatically. + --no -n Answer all questions with "no" automatically. + --cygwin -c Use "options" as value for CYGWIN environment var. + --name -N sshd windows service name. + --port -p sshd listens on port n. + --user -u privileged user for service, default 'cyg_server'. + --pwd -w Use "pwd" as password for privileged user. + --privileged On Windows XP, require privileged user + instead of LocalSystem for sshd service. + +Installing sshd as daemon via ssh-host-config is recommended. + +Alternatively you can start sshd via inetd, if you have the inetutils +package installed. Just run ssh-host-config, but answer "no" when asked +to install sshd as service. The ssh-host-config script also adds the +required lines to /etc/inetd.conf and /etc/services. + +================== +User configuration +================== + +Any user can simplify creating the own private and public keys by running + + /usr/bin/ssh-user-config + +To support testing and unattended installation ssh-user-config got +some options as well: + +usage: ssh-user-config [OPTION]... +Options: + --debug -d Enable shell's debug output. + --yes -y Answer all questions with "yes" automatically. + --no -n Answer all questions with "no" automatically. + --passphrase -p word Use "word" as passphrase automatically. + +Please note that OpenSSH does never use the value of $HOME to +search for the users configuration files! It always uses the +value of the pw_dir field in /etc/passwd as the home directory. +If no home directory is set in /etc/passwd, the root directory +is used instead! + +================ +Building OpenSSH +================ + +Building from source is easy. Just unpack the source archive, cd to that +directory, and call cygport: + + cygport openssh.cygport all + +You must have installed the following packages to be able to build OpenSSH +with the aforementioned cygport script: + + zlib + crypt + libssl-devel + libedit-devel + libkrb5-devel + +Please send requests, error reports etc. to cygwin@cygwin.com. + + +Have fun, + +Corinna Vinschen +Cygwin Developer +Red Hat Inc. diff --git a/aosp/external/openssh/contrib/cygwin/ssh-host-config b/aosp/external/openssh/contrib/cygwin/ssh-host-config new file mode 100644 index 0000000000000000000000000000000000000000..a8572e2ac879f3731999d3d8d3cb5e58883298aa --- /dev/null +++ b/aosp/external/openssh/contrib/cygwin/ssh-host-config @@ -0,0 +1,714 @@ +#!/bin/bash +# +# ssh-host-config, Copyright 2000-2014 Red Hat Inc. +# +# This file is part of the Cygwin port of OpenSSH. +# +# Permission to use, copy, modify, and distribute this software for any +# purpose with or without fee is hereby granted, provided that the above +# copyright notice and this permission notice appear in all copies. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS +# OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +# MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. +# IN NO EVENT SHALL THE ABOVE COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, +# DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR +# OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR +# THE USE OR OTHER DEALINGS IN THE SOFTWARE. + +# ====================================================================== +# Initialization +# ====================================================================== + +CSIH_SCRIPT=/usr/share/csih/cygwin-service-installation-helper.sh + +# List of apps used.

It assembles a list of one or more +fingerprints (as described below) and tries to log in with each key, to +see if any of them are already installed (of course, if you are not using +.Xr ssh-agent 1 +this may result in you being repeatedly prompted for pass-phrases). +It then assembles a list of those that failed to log in, and using ssh, +enables logins with those keys on the remote server. By default it adds +the keys by appending them to the remote user's +.Pa ~/.ssh/authorized_keys +(creating the file, and directory, if necessary). It is also capable +of detecting if the remote system is a NetScreen, and using its +.Ql set ssh pka-dsa key ... +command instead. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl i Ar identity_file +Use only the key(s) contained in +.Ar identity_file +(rather than looking for identities via +.Xr ssh-add 1 +or in the +.Ic default_ID_file ) . +If the filename does not end in +.Pa .pub +this is added. If the filename is omitted, the +.Ic default_ID_file +is used. +.Pp +Note that this can be used to ensure that the keys copied have the +comment one prefers and/or extra options applied, by ensuring that the +key file has these set as preferred before the copy is attempted. +.It Fl f +Forced mode: doesn't check if the keys are present on the remote server. +This means that it does not need the private key. Of course, this can result +in more than one copy of the key being installed on the remote system. +.It Fl n +do a dry-run. Instead of installing keys on the remote system simply +prints the key(s) that would have been installed. +.It Fl s +SFTP mode: usually the public keys are installed by executing commands on the remote side. +With this option the user's +.Pa ~/.ssh/authorized_keys +file will be downloaded, modified locally and uploaded with sftp. +This option is useful if the server has restrictions on commands which can be used on the remote side. +.It Fl h , Fl ? +Print Usage summary +.It Fl p Ar port , Fl o Ar ssh_option +These two options are simply passed through untouched, along with their +argument, to allow one to set the port or other +.Xr ssh 1 +options, respectively. +.Pp +Rather than specifying these as command line options, it is often better to use (per-host) settings in +.Xr ssh 1 Ns 's +configuration file: +.Xr ssh_config 5 . +.El +.Pp +Default behaviour without +.Fl i , +is to check if +.Ql ssh-add -L +provides any output, and if so those keys are used. Note that this results in +the comment on the key being the filename that was given to +.Xr ssh-add 1 +when the key was loaded into your +.Xr ssh-agent 1 +rather than the comment contained in that file, which is a bit of a shame. +Otherwise, if +.Xr ssh-add 1 +provides no keys contents of the +.Ic default_ID_file +will be used. +.Pp +The +.Ic default_ID_file +is the most recent file that matches: +.Pa ~/.ssh/id*.pub , +(excluding those that match +.Pa ~/.ssh/*-cert.pub ) +so if you create a key that is not the one you want +.Nm +to use, just use +.Xr touch 1 +on your preferred key's +.Pa .pub +file to reinstate it as the most recent. +.Pp +.Sh EXAMPLES +If you have already installed keys from one system on a lot of remote +hosts, and you then create a new key, on a new client machine, say, +it can be difficult to keep track of which systems on which you've +installed the new key. One way of dealing with this is to load both +the new key and old key(s) into your +.Xr ssh-agent 1 . +Load the new key first, without the +.Fl c +option, then load one or more old keys into the agent, possibly by +ssh-ing to the client machine that has that old key, using the +.Fl A +option to allow agent forwarding: +.Pp +.D1 user@newclient$ ssh-add +.D1 user@newclient$ ssh -A old.client +.D1 user@oldl$ ssh-add -c +.D1 No ... prompt for pass-phrase ... +.D1 user@old$ logoff +.D1 user@newclient$ ssh someserver +.Pp +now, if the new key is installed on the server, you'll be allowed in +unprompted, whereas if you only have the old key(s) enabled, you'll be +asked for confirmation, which is your cue to log back out and run +.Pp +.D1 user@newclient$ ssh-copy-id -i someserver +.Pp +The reason you might want to specify the -i option in this case is to +ensure that the comment on the installed key is the one from the +.Pa .pub +file, rather than just the filename that was loaded into your agent. +It also ensures that only the id you intended is installed, rather than +all the keys that you have in your +.Xr ssh-agent 1 . +Of course, you can specify another id, or use the contents of the +.Xr ssh-agent 1 +as you prefer. +.Pp +Having mentioned +.Xr ssh-add 1 Ns 's +.Fl c +option, you might consider using this whenever using agent forwarding +to avoid your key being hijacked, but it is much better to instead use +.Xr ssh 1 Ns 's +.Ar ProxyCommand +and +.Fl W +option, +to bounce through remote servers while always doing direct end-to-end +authentication. This way the middle hop(s) don't get access to your +.Xr ssh-agent 1 . +A web search for +.Ql ssh proxycommand nc +should prove enlightening (N.B. the modern approach is to use the +.Fl W +option, rather than +.Xr nc 1 ) . +.Sh "SEE ALSO" +.Xr ssh 1 , +.Xr ssh-agent 1 , +.Xr sshd 8 diff --git a/aosp/external/openssh/contrib/sshd.pam.freebsd b/aosp/external/openssh/contrib/sshd.pam.freebsd new file mode 100644 index 0000000000000000000000000000000000000000..c0bc36410e4071e1f7e5d8dd6ed4356a164cc679 --- /dev/null +++ b/aosp/external/openssh/contrib/sshd.pam.freebsd @@ -0,0 +1,5 @@ +sshd auth required pam_unix.so try_first_pass +sshd account required pam_unix.so +sshd password required pam_permit.so +sshd session required pam_permit.so + diff --git a/aosp/external/openssh/contrib/sshd.pam.generic b/aosp/external/openssh/contrib/sshd.pam.generic new file mode 100644 index 0000000000000000000000000000000000000000..215f0fe300a47cfd982dcdee2110c7bff96bce93 --- /dev/null +++ b/aosp/external/openssh/contrib/sshd.pam.generic @@ -0,0 +1,8 @@ +#%PAM-1.0 +auth required /lib/security/pam_unix.so shadow nodelay +account required /lib/security/pam_nologin.so +account required /lib/security/pam_unix.so +password required /lib/security/pam_cracklib.so +password required /lib/security/pam_unix.so shadow nullok use_authtok +session required /lib/security/pam_unix.so +session required /lib/security/pam_limits.so diff --git a/aosp/external/openssh/contrib/suse/openssh.spec b/aosp/external/openssh/contrib/suse/openssh.spec new file mode 100644 index 0000000000000000000000000000000000000000..28b9086f4cab7920e19d2d9b022b4f05647315a9 --- /dev/null +++ b/aosp/external/openssh/contrib/suse/openssh.spec @@ -0,0 +1,245 @@ +# Default values for additional components +%define build_x11_askpass 1 + +# Define the UID/GID to use for privilege separation +%define sshd_gid 65 +%define sshd_uid 71 + +# The version of x11-ssh-askpass to use +%define xversion 1.2.4.1 + +# Allow the ability to override defaults with -D skip_xxx=1 +%{?skip_x11_askpass:%define build_x11_askpass 0} + +Summary: OpenSSH, a free Secure Shell (SSH) protocol implementation +Name: openssh +Version: 9.0p1 +URL: https://www.openssh.com/ +Release: 1 +Source0: openssh-%{version}.tar.gz +Source1: x11-ssh-askpass-%{xversion}.tar.gz +License: BSD +Group: Productivity/Networking/SSH +BuildRoot: %{_tmppath}/openssh-%{version}-buildroot +PreReq: openssl +Obsoletes: ssh +Provides: ssh +# +# (Build[ing] Prereq[uisites] only work for RPM 2.95 and newer.) +# building prerequisites -- stuff for +# OpenSSL (openssl-devel), +# and Gnome (glibdev, gtkdev, and gnlibsd) +# +BuildPrereq: openssl +BuildPrereq: zlib-devel +#BuildPrereq: glibdev +#BuildPrereq: gtkdev +#BuildPrereq: gnlibsd + +%package askpass +Summary: A passphrase dialog for OpenSSH and the X window System. +Group: Productivity/Networking/SSH +Requires: openssh = %{version} +Obsoletes: ssh-extras +Provides: openssh:${_libdir}/ssh/ssh-askpass + +%if %{build_x11_askpass} +BuildPrereq: XFree86-devel +%endif + +%description +Ssh (Secure Shell) is a program for logging into a remote machine and for +executing commands in a remote machine.

Many C preprocessor symbols affect which code + * gets compiled here. + * + * The code is designed to make it easy to modify a particular + * recording method, without affecting other methods nor requiring so + * many nested conditional compilation blocks as were commonplace in + * the old code. + * + * For login recording, we try to use the local system's libraries as + * these are clearly most likely to work correctly. For utmp systems + * this usually means login() and logout() or setutent() etc., probably + * in libutil, along with logwtmp() etc. On these systems, we fall back + * to writing the files directly if we have to, though this method + * requires very thorough testing so we do not corrupt local auditing + * information. These files and their access methods are very system + * specific indeed. + * + * For utmpx systems, the corresponding library functions are + * setutxent() etc. To the author's knowledge, all utmpx systems have + * these library functions and so no direct write is attempted. If such + * a system exists and needs support, direct analogues of the [uw]tmp + * code should suffice. + * + * Retrieving the time of last login ('lastlog') is in some ways even + * more problemmatic than login recording. Some systems provide a + * simple table of all users which we seek based on uid and retrieve a + * relatively standard structure. Others record the same information in + * a directory with a separate file, and others don't record the + * information separately at all. For systems in the latter category, + * we look backwards in the wtmp or wtmpx file for the last login entry + * for our user. Naturally this is slower and on busy systems could + * incur a significant performance penalty. + * + * Calling the new code + * -------------------- + * + * In OpenSSH all login recording and retrieval is performed in + * login.c. Here you'll find working examples. Also, in the logintest.c + * program there are more examples. + * + * Internal handler calling method + * ------------------------------- + * + * When a call is made to login_login() or login_logout(), both + * routines set a struct logininfo flag defining which action (log in, + * or log out) is to be taken. They both then call login_write(), which + * calls whichever of the many structure-specific handlers autoconf + * selects for the local system. + * + * The handlers themselves handle system data structure specifics. Both + * struct utmp and struct utmpx have utility functions (see + * construct_utmp*()) to try to make it simpler to add extra systems + * that introduce new features to either structure. + * + * While it may seem terribly wasteful to replicate so much similar + * code for each method, experience has shown that maintaining code to + * write both struct utmp and utmpx in one function, whilst maintaining + * support for all systems whether they have library support or not, is + * a difficult and time-consuming task. + * + * Lastlog support proceeds similarly. Functions login_get_lastlog() + * (and its OpenSSH-tuned friend login_get_lastlog_time()) call + * getlast_entry(), which tries one of three methods to find the last + * login time. It uses local system lastlog support if it can, + * otherwise it tries wtmp or wtmpx before giving up and returning 0, + * meaning "tilt". + * + * Maintenance + * ----------- + * + * In many cases it's possible to tweak autoconf to select the correct + * methods for a particular platform, either by improving the detection + * code (best), or by presetting DISABLE_ or CONF__FILE + * symbols for the platform. + * + * Use logintest to check which symbols are defined before modifying + * configure.ac and loginrec.c. (You have to build logintest yourself + * with 'make logintest' as it's not built by default.) + * + * Otherwise, patches to the specific method(s) are very helpful! + */ + +#include "includes.h" + +#include +#include +#include +#ifdef HAVE_SYS_TIME_H +# include +#endif + +#include + +#include +#include +#include +#ifdef HAVE_PATHS_H +# include +#endif +#include +#include +#include +#include +#include +#include + +#include "xmalloc.h" +#include "sshkey.h" +#include "hostfile.h" +#include "ssh.h" +#include "loginrec.h" +#include "log.h" +#include "atomicio.h" +#include "packet.h" +#include "canohost.h" +#include "auth.h" +#include "sshbuf.h" +#include "ssherr.h" +#include "misc.h" + +#ifdef HAVE_UTIL_H +# include +#endif + +/** + ** prototypes for helper functions in this file + **/ + +#if HAVE_UTMP_H +void set_utmp_time(struct logininfo *li, struct utmp *ut); +void construct_utmp(struct logininfo *li, struct utmp *ut); +#endif + +#ifdef HAVE_UTMPX_H +void set_utmpx_time(struct logininfo *li, struct utmpx *ut); +void construct_utmpx(struct logininfo *li, struct utmpx *ut); +#endif + +int utmp_write_entry(struct logininfo *li); +int utmpx_write_entry(struct logininfo *li); +int wtmp_write_entry(struct logininfo *li); +int wtmpx_write_entry(struct logininfo *li); +int lastlog_write_entry(struct logininfo *li); +int syslogin_write_entry(struct logininfo *li); + +int getlast_entry(struct logininfo *li); +int lastlog_get_entry(struct logininfo *li); +int utmpx_get_entry(struct logininfo *li); +int wtmp_get_entry(struct logininfo *li); +int wtmpx_get_entry(struct logininfo *li); + +extern struct sshbuf *loginmsg; + +/* pick the shortest string */ +#define MIN_SIZEOF(s1,s2) (sizeof(s1) < sizeof(s2) ? sizeof(s1) : sizeof(s2)) + +/** + ** platform-independent login functions + **/ + +/* + * login_login(struct logininfo *) - Record a login + * + * Call with a pointer to a struct logininfo initialised with + * login_init_entry() or login_alloc_entry() + * + * Returns: + * >0 if successful + * 0 on failure (will use OpenSSH's logging facilities for diagnostics) + */ +int +login_login(struct logininfo *li) +{ + li->type = LTYPE_LOGIN; + return (login_write(li)); +} + + +/* + * login_logout(struct logininfo *) - Record a logout + * + * Call as with login_login() + * + * Returns: + * >0 if successful + * 0 on failure (will use OpenSSH's logging facilities for diagnostics) + */ +int +login_logout(struct logininfo *li) +{ + li->type = LTYPE_LOGOUT; + return (login_write(li)); +} + +/* + * login_get_lastlog_time(int) - Retrieve the last login time + * + * Retrieve the last login time for the given uid.

The elements + * are singly linked for minimum space and pointer manipulation overhead at + * the expense of O(n) removal for arbitrary elements. New elements can be + * added to the list after an existing element or at the head of the list. + * Elements being removed from the head of the list should use the explicit + * macro for this purpose for optimum efficiency. A singly-linked list may + * only be traversed in the forward direction. Singly-linked lists are ideal + * for applications with large datasets and few or no removals or for + * implementing a LIFO queue. + * + * A list is headed by a single forward pointer (or an array of forward + * pointers for a hash table header). The elements are doubly linked + * so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before + * or after an existing element or at the head of the list. A list + * may only be traversed in the forward direction. + * + * A simple queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are singly + * linked to save space, so elements can only be removed from the + * head of the list. New elements can be added to the list before or after + * an existing element, at the head of the list, or at the end of the + * list. A simple queue may only be traversed in the forward direction. + * + * A tail queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are doubly + * linked so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before or + * after an existing element, at the head of the list, or at the end of + * the list. A tail queue may be traversed in either direction. + * + * An XOR simple queue is used in the same way as a regular simple queue. + * The difference is that the head structure also includes a "cookie" that + * is XOR'd with the queue pointer (first, last or next) to generate the + * real pointer value. + * + * For details on the use of these macros, see the queue(3) manual page. + */ + +#if defined(QUEUE_MACRO_DEBUG) || (defined(_KERNEL) && defined(DIAGNOSTIC)) +#define _Q_INVALID ((void *)-1) +#define _Q_INVALIDATE(a) (a) = _Q_INVALID +#else +#define _Q_INVALIDATE(a) +#endif + +/* + * Singly-linked List definitions. + */ +#define SLIST_HEAD(name, type) \ +struct name { \ + struct type *slh_first;

webauthn test

+

+This is a demo/test page for generating FIDO keys and signatures in SSH +formats. The page initially displays a form to generate a FIDO key and +convert it to a SSH public key. +

+

+Once a key has been generated, an additional form will be displayed to +allow signing of data using the just-generated key. The data may be signed +as either a raw SSH signature or wrapped in a sshsig message (the latter is +easier to test using command-line tools. +

+

+Lots of debugging is printed along the way. +

files between hosts on a network. +.Pp +It uses +.Xr ssh 1 +for data transfer, and uses the same authentication and provides the +same security as a login session. +.Pp +.Nm +will ask for passwords or passphrases if they are needed for +authentication. +.Pp +The +.Ar source +and +.Ar target +may be specified as a local pathname, a remote host with optional path +in the form +.Sm off +.Oo user @ Oc host : Op path , +.Sm on +or a URI in the form +.Sm off +.No scp:// Oo user @ Oc host Oo : port Oc Op / path . +.Sm on +Local file names can be made explicit using absolute or relative pathnames +to avoid +.Nm +treating file names containing +.Sq :\& +as host specifiers. +.Pp +When copying between two remote hosts, if the URI format is used, a +.Ar port +cannot be specified on the +.Ar target +if the +.Fl R +option is used. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl 3 +Copies between two remote hosts are transferred through the local host. +Without this option the data is copied directly between the two remote +hosts. +Note that, when using the legacy SCP protocol (via the +.Fl O +flag), this option +selects batch mode for the second host as +.Nm +cannot ask for passwords or passphrases for both hosts. +This mode is the default. +.It Fl 4 +Forces +.Nm +to use IPv4 addresses only. +.It Fl 6 +Forces +.Nm +to use IPv6 addresses only. +.It Fl A +Allows forwarding of +.Xr ssh-agent 1 +to the remote system. +The default is not to forward an authentication agent. +.It Fl B +Selects batch mode (prevents asking for passwords or passphrases). +.It Fl C +Compression enable. +Passes the +.Fl C +flag to +.Xr ssh 1 +to enable compression. +.It Fl c Ar cipher +Selects the cipher to use for encrypting the data transfer. +This option is directly passed to +.Xr ssh 1 . +.It Fl D Ar sftp_server_path +When using the SFTP protocol support via +.Fl M , +connect directly to a local SFTP server program rather than a +remote one via +.Xr ssh 1 . +This option may be useful in debugging the client and server. +.It Fl F Ar ssh_config +Specifies an alternative +per-user configuration file for +.Nm ssh . +This option is directly passed to +.Xr ssh 1 . +.It Fl i Ar identity_file +Selects the file from which the identity (private key) for public key +authentication is read. +This option is directly passed to +.Xr ssh 1 . +.It Fl J Ar destination +Connect to the target host by first making an +.Nm +connection to the jump host described by +.Ar destination +and then establishing a TCP forwarding to the ultimate destination from +there. +Multiple jump hops may be specified separated by comma characters. +This is a shortcut to specify a +.Cm ProxyJump +configuration directive. +This option is directly passed to +.Xr ssh 1 . +.It Fl l Ar limit +Limits the used bandwidth, specified in Kbit/s. +.It Fl O +Use the legacy SCP protocol for file transfers instead of the SFTP protocol. +Forcing the use of the SCP protocol may be necessary for servers that do +not implement SFTP, for backwards-compatibility for particular filename +wildcard patterns and for expanding paths with a +.Sq ~ +prefix for older SFTP servers. +.It Fl o Ar ssh_option +Can be used to pass options to +.Nm ssh +in the format used in +.Xr ssh_config 5 . +This is useful for specifying options +for which there is no separate +.Nm scp +command-line flag. +For full details of the

+.Sq P , +because +.Fl p +is already reserved for preserving the times and mode bits of the file. +.It Fl p +Preserves modification times, access times, and file mode bits from the +source file. +.It Fl q +Quiet mode: disables the progress meter as well as warning and diagnostic +messages from +.Xr ssh 1 . +.It Fl R +Copies between two remote hosts are performed by connecting to the origin +host and executing +.Nm +there. +This requires that +.Nm +running on the origin host can authenticate to the destination host without +requiring a password. +.It Fl r +Recursively copy entire directories. +Note that +.Nm +follows symbolic links encountered in the tree traversal. +.It Fl S Ar program +Name of +.Ar program +to use for the encrypted connection. +The program must understand +.Xr ssh 1 +options. +.It Fl T +Disable strict filename checking. +By default when copying files from a remote host to a local directory +.Nm +checks that the received filenames match those requested on the command-line +to prevent the remote end from sending unexpected or unwanted files. +Because of differences in how various operating systems and shells interpret +filename wildcards, these checks may cause wanted files to be rejected. +This option disables these checks at the expense of fully trusting that +the server will not send unexpected filenames. +.It Fl v +Verbose mode. +Causes +.Nm +and

+.Op Fl D Ar sftp_server_path +.Op Fl F Ar ssh_config +.Op Fl i Ar identity_file +.Op Fl J Ar destination +.Op Fl l Ar limit +.Op Fl o Ar ssh_option +.Op Fl P Ar port +.Op Fl R Ar num_requests +.Op Fl S Ar program +.Op Fl s Ar subsystem | sftp_server +.Ar destination +.Sh DESCRIPTION +.Nm +is a file transfer program, similar to +.Xr ftp 1 , +which performs all operations over an encrypted +.Xr ssh 1 +transport. +It may also use many features of ssh, such as public key authentication and +compression. +.Pp +The +.Ar destination +may be specified either as +.Sm off +.Oo user @ Oc host Op : path +.Sm on +or as a URI in the form +.Sm off +.No sftp:// Oo user @ Oc host Oo : port Oc Op / path . +.Sm on +.Pp +If the +.Ar destination +includes a +.Ar path +and it is not a directory, +.Nm +will retrieve files automatically if a non-interactive +authentication method is used; otherwise it will do so after +successful interactive authentication. +.Pp +If no +.Ar path +is specified, or if the +.Ar path +is a directory, +.Nm +will log in to the specified +.Ar host +and enter interactive command mode, changing to the remote directory +if one was specified. +An optional trailing slash can be used to force the +.Ar path +to be interpreted as a directory. +.Pp +Since the destination formats use colon characters to delimit host +names from path names or port numbers, IPv6 addresses must be +enclosed in square brackets to avoid ambiguity. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl 4 +Forces +.Nm +to use IPv4 addresses only. +.It Fl 6 +Forces +.Nm +to use IPv6 addresses only. +.It Fl A +Allows forwarding of +.Xr ssh-agent 1 +to the remote system. +The default is not to forward an authentication agent. +.It Fl a +Attempt to continue interrupted transfers rather than overwriting +existing partial or complete copies of files. +If the partial contents differ from those being transferred, +then the resultant file is likely to be corrupt. +.It Fl B Ar buffer_size +Specify the size of the buffer that +.Nm +uses when transferring files. +Larger buffers require fewer round trips at the cost of higher +memory consumption. +The default is 32768 bytes. +.It Fl b Ar batchfile +Batch mode reads a series of commands from an input +.Ar batchfile +instead of +.Em stdin . +Since it lacks user interaction, it should be used in conjunction with +non-interactive authentication to obviate the need to enter a password +at connection time (see +.Xr sshd 8 +and +.Xr ssh-keygen 1 +for details). +.Pp +A +.Ar batchfile +of +.Sq \- +may be used to indicate standard input. +.Nm +will abort if any of the following +commands fail: +.Ic get , put , reget , reput , rename , ln , +.Ic rm , mkdir , chdir , ls , +.Ic lchdir , copy , cp , chmod , chown , +.Ic chgrp , lpwd , df , symlink , +and +.Ic lmkdir . +.Pp +Termination on error can be suppressed on a command by command basis by +prefixing the command with a +.Sq \- +character (for example, +.Ic -rm /tmp/blah* ) . +Echo of the command may be suppressed by prefixing the command with a +.Sq @ +character. +These two prefixes may be combined in any order, for example +.Ic -@ls /bsd . +.It Fl C +Enables compression (via ssh's +.Fl C +flag). +.It Fl c Ar cipher +Selects the cipher to use for encrypting the data transfers. +This option is directly passed to +.Xr ssh 1 . +.It Fl D Ar sftp_server_path +Connect directly to a local sftp server +(rather than via +.Xr ssh 1 ) . +This option may be useful in debugging the client and server. +.It Fl F Ar ssh_config +Specifies an alternative +per-user configuration file for +.Xr ssh 1 . +This option is directly passed to +.Xr ssh 1 . +.It Fl f +Requests that files be flushed to disk immediately after transfer. +When uploading files, this feature is only enabled if the server +implements the "fsync@openssh.com" extension. +.It Fl i Ar identity_file +Selects the file from which the identity (private key) for public key +authentication is read. +This option is directly passed to +.Xr ssh 1 . +.It Fl J Ar destination +Connect to the target host by first making an +.Nm +connection to the jump host described by +.Ar destination +and then establishing a TCP forwarding to the ultimate destination from +there. +Multiple jump hops may be specified separated by comma characters. +This is a shortcut to specify a +.Cm ProxyJump +configuration directive. +This option is directly passed to +.Xr ssh 1 . +.It Fl l Ar limit +Limits the used bandwidth, specified in Kbit/s. +.It Fl N +Disables quiet mode, e.g. to override the implicit quiet mode set by the +.Fl b +flag. +.It Fl o Ar ssh_option +Can be used to pass options to +.Nm ssh +in the format used in +.Xr ssh_config 5 . +This is useful for specifying options +for which there is no separate +.Nm sftp +command-line flag. +For example, to specify an alternate port use: +.Ic sftp -oPort=24 . +For full details of the options listed below, and their possible values,

port +Specifies the port to connect to on the remote host. +.It Fl p +Preserves modification times, access times, and modes from the +original files transferred. +.It Fl q +Quiet mode: disables the progress meter as well as warning and +diagnostic messages from +.Xr ssh 1 . +.It Fl R Ar num_requests +Specify how many requests may be outstanding at any one time. +Increasing this may slightly improve file transfer speed +but will increase memory usage. +The default is 64 outstanding requests. +.It Fl r +Recursively copy entire directories when uploading and downloading. +Note that +.Nm +does not follow symbolic links encountered in the tree traversal. +.It Fl S Ar program +Name of the +.Ar program +to use for the encrypted connection. +The program must understand +.Xr ssh 1 +options. +.It Fl s Ar subsystem | sftp_server +Specifies the SSH2 subsystem or the path for an sftp server +on the remote host. +A path is useful when the remote +.Xr sshd 8 +does not have an sftp

+.Fl T +.Ar pubkey ... +.Sh DESCRIPTION +.Nm +adds private key identities to the authentication agent, +.Xr ssh-agent 1 . +When run without arguments, it adds the files +.Pa ~/.ssh/id_rsa , +.Pa ~/.ssh/id_ecdsa , +.Pa ~/.ssh/id_ecdsa_sk , +.Pa ~/.ssh/id_ed25519 , +.Pa ~/.ssh/id_ed25519_sk , +and +.Pa ~/.ssh/id_dsa . +After loading a private key, +.Nm +will try to load corresponding certificate information from the +filename obtained by appending +.Pa -cert.pub +to the name of the private key file. +Alternative file names can be given on the command line. +.Pp +If any file requires a passphrase, +.Nm +asks for the passphrase from the user. +The passphrase is read from the user's tty. +.Nm +retries the last passphrase if multiple identity files are given. +.Pp +The authentication agent must be running and the +.Ev SSH_AUTH_SOCK +environment variable must contain the name of its socket for +.Nm +to work. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl c +Indicates that added identities should be subject to confirmation before +being used for authentication. +Confirmation is performed by +.Xr ssh-askpass 1 . +Successful confirmation is signaled by a zero exit status from +.Xr ssh-askpass 1 , +rather than text entered into the requester. +.It Fl D +Deletes all identities from the agent. +.It Fl d +Instead of adding identities, removes identities from the agent. +If +.Nm +has been run without arguments, the keys for the default identities and +their corresponding certificates will be removed. +Otherwise, the argument list will be interpreted as a list of paths to +public key files to specify keys and certificates to be removed from the agent. +If no public key is found at a given path, +.Nm +will append +.Pa .pub +and retry. +If the argument list consists of +.Dq - +then +.Nm +will read public keys to be removed from standard input. +.It Fl E Ar fingerprint_hash +Specifies the hash algorithm used when displaying key fingerprints. +Valid options are: +.Dq md5 +and +.Dq sha256 . +The default is +.Dq sha256 . +.It Fl e Ar pkcs11 +Remove keys provided by the PKCS#11 shared library +.Ar pkcs11 . +.It Fl H Ar hostkey_file +Specifies a known hosts file to look up hostkeys when using +destination-constrained keys via the +.Fl h +flag. +This option may be specified multiple times to allow multiple files to be +searched. +If no files are specified, +.Nm +will use the default +.Xr ssh_config 5 +known hosts files: +.Pa ~/.ssh/known_hosts , +.Pa ~/.ssh/known_hosts2 , +.Pa /etc/ssh/ssh_known_hosts , +and +.Pa /etc/ssh/ssh_known_hosts2 . +.It Fl h Ar destination_constraint +When adding keys, constrain them to be usable only through specific hosts or to +specific destinations. +.Pp +Destination constraints of the form +.Sq [user@]dest-hostname +permit use of the key only from the origin host (the one running +.Xr ssh-agent 1 ) +to the listed destination host, with optional user name. +.Pp +Constraints of the form +.Sq src-hostname>[user@]dst-hostname +allow a key available on a forwarded +.Xr ssh-agent 1 +to be used through a particular host (as specified by +.Sq src-hostname ) +to authenticate to a further host, +specified by +.Sq dst-hostname . +.Pp +Multiple destination constraints may be added when loading keys. +When attempting authentication with a key that has destination constraints, +the whole connection path, including +.Xr ssh-agent 1 +forwarding, is tested against those constraints and each +hop must be permitted for the attempt to succeed. +For example, if key is forwarded to a remote host, +.Sq host-b , +and is attempting authentication to another host, +.Sq host-c , +then the operation will be successful only if +.Sq host-b +was permitted from the origin host and the subsequent +.Sq host-b>host-c +hop is also permitted by destination constraints. +.Pp +Hosts are identified by their host keys, and are looked up from known hosts +files by +.Nm . +Wildcards patterns may be used for hostnames and certificate host +keys are supported. +By default, keys added by +.Nm +are not destination constrained. +.Pp +Destination constraints were added in OpenSSH release 8.9. +Support in both the remote SSH client and server is required when using +destination-constrained keys over a forwarded +.Xr ssh-agent 1 +channel. +.Pp +It is also important to note that destination constraints can only be +enforced by +.Xr ssh-agent 1 +when a key is used, or when it is forwarded by a +.Sy cooperating +.Xr ssh 1 . +Specifically, it does not prevent an attacker with access to a remote +.Ev SSH_AUTH_SOCK +from forwarding it again and using it on a different host (but only to +a permitted destination). +.It Fl K +Load resident keys from a FIDO authenticator. +.It Fl k +When loading keys into or deleting keys from the agent, process plain private +keys only and skip certificates. +.It Fl L +Lists public key parameters of all identities currently represented +by the agent. +.It Fl l +Lists fingerprints of all identities currently represented by the agent. +.It Fl q +Be quiet after a successful operation. +.It Fl S Ar provider +Specifies a path to a library that will be used when adding +FIDO authenticator-hosted keys, overriding the default of using the +internal USB HID support. +.It Fl s Ar pkcs11 +Add keys provided by the PKCS#11 shared library +.Ar pkcs11 . +.It Fl T Ar pubkey ... +Tests whether the private keys that correspond to the specified +.Ar pubkey +files are usable by performing sign and verify operations on each. +.It Fl t Ar life +Set a maximum lifetime when adding identities to an agent. +The lifetime may be specified in seconds or in a time format +specified in +.Xr sshd_config 5 . +.It Fl v +Verbose mode. +Causes +.Nm +to print debugging messages about its progress. +This is helpful in debugging problems. +Multiple +.Fl v +options increase the verbosity. +The maximum is 3. +.It Fl X +Unlock the agent. +.It Fl x +Lock the agent with a password. +.El +.Sh ENVIRONMENT +.Bl -tag -width Ds +.It Ev "DISPLAY", "SSH_ASKPASS" and "SSH_ASKPASS_REQUIRE" +If +.Nm +needs a passphrase, it will read the passphrase from the current +terminal if it was run from a terminal. +If +.Nm +does not have a terminal associated with it but +.Ev DISPLAY +and +.Ev SSH_ASKPASS +are set, it will execute the program specified by +.Ev SSH_ASKPASS +(by default +.Dq ssh-askpass ) +and open an X11 window to read the passphrase. +This is particularly useful when calling +.Nm +from a +.Pa .xsession +or related script. +.Pp +.Ev SSH_ASKPASS_REQUIRE +allows further control over the use of an askpass program. +If this variable is set to +.Dq never +then +.Nm +will never attempt to use one. +If it is set to +.Dq prefer , +then +.Nm +will prefer to

located +and automatically used for authentication when logging in to other +machines using +.Xr ssh 1 . +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl a Ar bind_address +Bind the agent to the +.Ux Ns -domain +socket +.Ar bind_address . +The default is +.Pa $TMPDIR/ssh-XXXXXXXXXX/agent.\*(Ltppid\*(Gt . +.It Fl c +Generate C-shell commands on +.Dv stdout . +This is the default if +.Ev SHELL +looks like it's a csh style of shell. +.It Fl D +Foreground mode. +When this option is specified, +.Nm +will not fork. +.It Fl d +Debug mode. +When this option is specified, +.Nm +will not fork and will write debug information to standard error. +.It Fl E Ar fingerprint_hash +Specifies the hash algorithm used when displaying key fingerprints. +Valid options are: +.Dq md5 +and +.Dq sha256 . +The default is +.Dq sha256 . +.It Fl k +Kill the current agent (given by the +.Ev SSH_AGENT_PID +environment variable). +.It Fl P Ar allowed_providers +Specify a pattern-list of acceptable paths for PKCS#11 provider and FIDO +authenticator middleware shared libraries that may be used with the +.Fl S +or +.Fl s +options to +.Xr ssh-add 1 . +Libraries that do not match the pattern list will be refused. +See PATTERNS in +.Xr ssh_config 5 +for a description of pattern-list syntax. +The default list is +.Dq /usr/lib/*,/usr/local/lib/* . +.It Fl s +Generate Bourne shell commands on +.Dv stdout . +This is the default if +.Ev SHELL +does not look like it's a csh style of shell. +.It Fl t Ar life +Set a default value for the maximum lifetime of identities added to the agent. +The lifetime may be specified in seconds or in a time format specified in +.Xr sshd_config 5 . +A lifetime specified for an identity with +.Xr ssh-add 1 +overrides this value. +Without this option the default maximum lifetime is forever. +.It Ar command Op Ar arg ... +If a command (and optional arguments) is given, +this is executed as a subprocess of the agent. +The agent exits automatically when the command given on the command +line terminates. +.El +.Pp +There are two main ways to get an agent set up. +The first is at the start of an X session, +where all other windows or programs are started as children of the +.Nm +program. +The agent starts a command under which its environment +variables are exported, for example +.Cm ssh-agent xterm & . +When the command terminates, so does the agent. +.Pp +The second method is used for a login session. +When +.Nm +is started, +it prints the shell commands required to set its environment variables, +which in turn can be evaluated in the calling shell, for example +.Cm eval `ssh-agent -s` . +.Pp +In both cases, +.Xr ssh 1 +looks at these environment variables +and uses them to establish a connection to the agent. +.Pp +The agent initially does not have any private keys. +Keys are added using +.Xr ssh-add 1 +or by +.Xr ssh 1 +when +.Cm AddKeysToAgent +is set in +.Xr ssh_config 5 . +Multiple identities may be stored in +.Nm +concurrently and +.Xr ssh 1 +will automatically use them if present. +.Xr ssh-add 1 +is also used to remove keys from +.Nm +and to query the keys that are held in one. +.Pp +Connections to +.Nm +may be forwarded from further remote hosts using the +.Fl A +option to +.Xr ssh 1 +(but see the caveats documented therein), +avoiding the need for authentication data to be stored on other machines. +Authentication passphrases and private keys never go over the network: +the connection to the agent is forwarded over SSH remote connections +and the result is returned to the requester, +allowing the user access to their identities anywhere in the network +in a secure fashion. +.Sh ENVIRONMENT +.Bl -tag -width "SSH_AGENT_PID" +.It Ev SSH_AGENT_PID +When +.Nm +starts, it stores the name of the agent's process ID (PID) in this variable. +.It Ev SSH_AUTH_SOCK +When +.Nm +starts, it creates a +.Ux Ns -domain +socket and stores its pathname in this variable. +It is accessible only to the current user, +but is easily abused by root or another instance of the same user. +.El +.Sh FILES +.Bl -tag -width Ds +.It Pa $TMPDIR/ssh-XXXXXXXXXX/agent. +.Ux Ns -domain +sockets used to contain the connection to the authentication agent. +These sockets should only be readable by the owner. +The sockets should get automatically removed when the agent exits. +.El +.Sh SEE ALSO +.Xr ssh 1 , +.Xr ssh-add 1 , +.Xr

protocol version 2. +.Pp +The type of key to be generated is specified with the +.Fl t +option. +If invoked without any arguments, +.Nm +will generate an RSA key. +.Pp +.Nm +is also used to generate groups for use in Diffie-Hellman group +exchange (DH-GEX). +See the +.Sx MODULI GENERATION +section for details. +.Pp +Finally, +.Nm +can be used to generate and update Key Revocation Lists, and to test whether +given keys have been revoked by one. +See the +.Sx KEY REVOCATION LISTS +section for details. +.Pp +Normally each user wishing to use SSH +with public key authentication runs this once to create the authentication +key in +.Pa ~/.ssh/id_dsa , +.Pa ~/.ssh/id_ecdsa , +.Pa ~/.ssh/id_ecdsa_sk , +.Pa ~/.ssh/id_ed25519 , +.Pa ~/.ssh/id_ed25519_sk +or +.Pa ~/.ssh/id_rsa . +Additionally, the system administrator may use this to generate host keys, +as seen in +.Pa /etc/rc . +.Pp +Normally this program generates the key and asks for a file in which +to store the private key. +The public key is stored in a file with the same name but +.Dq .pub +appended. +The program also asks for a passphrase. +The passphrase may be empty to indicate no passphrase +(host keys must have an empty passphrase), or it may be a string of +arbitrary length. +A passphrase is similar to a password, except it can be a phrase with a +series of words, punctuation, numbers, whitespace, or any string of +characters you want. +Good passphrases are 10-30 characters long, are +not simple sentences or otherwise easily guessable (English +prose has only 1-2 bits of entropy per character, and provides very bad +passphrases), and contain a mix of upper and lowercase letters, +numbers, and non-alphanumeric characters. +The passphrase can be changed later by using the +.Fl p +option. +.Pp +There is no way to recover a lost passphrase. +If the passphrase is lost or forgotten, a new key must be generated +and the corresponding public key copied to other machines. +.Pp +.Nm +will by default write keys in an OpenSSH-specific format. +This format is preferred as it offers better protection for +keys at rest as well as allowing storage of key comments within +the private key file itself. +The key comment may be useful to help identify the key. +The comment is initialized to +.Dq user@host +when the key is created, but can be changed using the +.Fl c +option. +.Pp +It is still possible for +.Nm +to write the previously-used PEM format private keys using the +.Fl m +flag. +This may be used when generating new keys, and existing new-format +keys may be converted using this option in conjunction with the +.Fl p +(change passphrase) flag. +.Pp +After a key is generated, +.Nm +will ask where the keys +should be placed to be activated. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl A +For each of the key types (rsa, dsa, ecdsa and ed25519) +for which host keys +do not exist, generate the host keys with the default key file path, +an empty passphrase, default bits for the key type, and default comment. +If +.Fl f +has also been specified, its argument is used as a prefix to the +default path for the resulting host key files. +This is used by +.Pa /etc/rc +to generate new host keys. +.It Fl a Ar rounds +When saving a private key, this option specifies the number of KDF +(key derivation function, currently +.Xr bcrypt_pbkdf 3 ) +rounds used. +Higher numbers result in slower passphrase verification and increased +resistance to brute-force password cracking (should the keys be stolen). +The default is 16 rounds. +.It Fl B +Show the bubblebabble digest of specified private or public key file. +.It Fl b Ar bits +Specifies the number of bits in the key to create. +For RSA keys, the minimum size is 1024 bits and the default is 3072 bits. +Generally, 3072 bits is considered sufficient. +DSA keys must be exactly 1024 bits as specified by FIPS 186-2. +For ECDSA keys, the +.Fl b +flag determines the key length by selecting from one of three elliptic +curve sizes: 256, 384 or 521 bits. +Attempting to use bit lengths other than these three values for ECDSA keys +will fail. +ECDSA-SK, Ed25519 and Ed25519-SK keys have a fixed length and the +.Fl b +flag will be ignored. +.It Fl C Ar comment +Provides a new comment. +.It Fl c +Requests changing the comment in the private and public key files. +The program will prompt for the file containing the private keys, for +the passphrase if the key has one, and for the new comment. +.It Fl D Ar pkcs11 +Download the public keys provided by the PKCS#11 shared library +.Ar pkcs11 . +When used in combination with +.Fl s , +this option indicates that a CA key resides in a PKCS#11 token (see the +.Sx CERTIFICATES +section for details). +.It Fl E Ar fingerprint_hash +Specifies the hash algorithm used when displaying key fingerprints. +Valid options are: +.Dq md5 +and +.Dq sha256 . +The default is +.Dq sha256 . +.It Fl e +This option will read a private or public OpenSSH key file and +print to stdout a public key in one of the formats specified by the +.Fl m +option. +The default export format is +.Dq RFC4716 . +This option allows exporting OpenSSH keys for use by other programs, including +several commercial SSH implementations. +.It Fl F Ar hostname | [hostname]:port +Search for the specified +.Ar hostname +(with optional port number) +in a +.Pa known_hosts +file, listing any occurrences found. +This option is useful to find hashed host names or addresses and may also be +used in conjunction with the +.Fl H +option to print found keys in a hashed format. +.It Fl f Ar filename +Specifies the filename of the key file. +.It Fl g +Use generic DNS format when printing fingerprint resource records using the +.Fl r +command. +.It Fl H +Hash a +.Pa known_hosts +file. +This replaces all hostnames and addresses with hashed representations +within the specified file; the original content is moved to a file with +a .old suffix. +These hashes may be used normally by +.Nm ssh +and +.Nm sshd , +but they do not reveal identifying information should the file's contents +be disclosed. +This option will not modify existing hashed hostnames and is therefore safe +to use on files that mix hashed and non-hashed names. +.It Fl h +When signing a key, create a host certificate instead of a user +certificate. +See the +.Sx CERTIFICATES +section for details. +.It Fl I Ar certificate_identity +Specify the key identity when signing a public key. +See the +.Sx CERTIFICATES +section for details. +.It Fl i +This option will read an unencrypted private (or public) key file +in the format specified by the +.Fl m +option and print an OpenSSH compatible private +(or public) key to stdout. +This option allows importing keys from other software, including several +commercial SSH implementations. +The default import format is +.Dq RFC4716 . +.It Fl K +Download resident keys from a FIDO authenticator. +Public and private key files will be written to the current directory for +each downloaded key. +If multiple FIDO authenticators are attached, keys will be downloaded from +the first touched authenticator. +.It Fl k +Generate a KRL file. +In this mode, +.Nm +will generate a KRL file at the location specified via the +.Fl f +flag that revokes every key or certificate presented on the command line. +Keys/certificates to be revoked may be specified by public key file or +using the format described in the +.Sx KEY REVOCATION LISTS +section. +.It Fl L +Prints the contents of one or more certificates. +.It Fl l +Show fingerprint of specified public key file. +For RSA and DSA keys +.Nm +tries to find the matching public key file and prints its fingerprint. +If combined with +.Fl v , +a visual ASCII art representation of the key is supplied with the +fingerprint. +.It Fl M Cm generate +Generate candidate Diffie-Hellman Group Exchange (DH-GEX) parameters for +eventual use by the +.Sq diffie-hellman-group-exchange-* +key exchange methods. +The numbers generated by this operation must be further screened before +use. +See the +.Sx MODULI GENERATION +section for more information. +.It Fl M Cm screen +Screen candidate parameters for Diffie-Hellman Group Exchange. +This will accept a list of candidate numbers and test that they are +safe (Sophie Germain) primes with acceptable group generators. +The results of this operation may be added to the +.Pa /etc/moduli +file. +See the +.Sx MODULI GENERATION +section for more information. +.It Fl m Ar key_format +Specify a key format for key generation, the +.Fl i +(import), +.Fl e +(export) conversion options, and the +.Fl p +change passphrase operation. +The latter may be used to convert between OpenSSH private key and PEM +private key formats. +The supported key formats are: +.Dq RFC4716 +(RFC 4716/SSH2 public or private key), +.Dq PKCS8 +(PKCS8 public or private key) +or +.Dq PEM +(PEM public key). +By default OpenSSH will write newly-generated private keys in its own +format, but when converting public keys for export the default format is +.Dq RFC4716 . +Setting a format of +.Dq PEM +when generating or updating a supported private key type will cause the +key to be stored in the legacy PEM private key format. +.It Fl N Ar new_passphrase +Provides the new passphrase. +.It Fl n Ar principals +Specify one or more principals (user or host names) to be included in +a certificate when signing a key. +Multiple principals may be specified, separated by commas. +See the +.Sx CERTIFICATES +section for details. +.It Fl O Ar option +Specify a key/value option. +These are specific to the operation that +.Nm +has been requested to perform. +.Pp +When signing certificates, one of the options listed in the +.Sx CERTIFICATES +section may be specified here. +.Pp +When performing moduli generation or screening, one of the options +listed in the +.Sx MODULI GENERATION +section may be specified. +.Pp +When generating a key that will be hosted on a FIDO authenticator, +this flag may be used to specify key-specific options. +Those supported at present are: +.Bl -tag -width Ds +.It Cm application +Override the default FIDO application/origin string of +.Dq ssh: . +This may be useful when generating host or domain-specific resident keys. +The specified application string must begin with +.Dq ssh: . +.It Cm challenge Ns = Ns Ar path +Specifies a path to a challenge string that will be passed to the +FIDO token during key generation. +The challenge string may be used as part of an out-of-band +protocol for key enrollment +(a random challenge is used by default). +.It Cm device +Explicitly specify a +.Xr fido 4 +device to use, rather than letting the token middleware select one. +.It Cm no-touch-required +Indicate that the generated private key should not require touch +events (user presence) when making signatures. +Note that +.Xr sshd 8 +will refuse such signatures by default, unless overridden via +an authorized_keys option. +.It Cm resident +Indicate that the key should be stored on the FIDO authenticator itself. +Resident keys may be supported on FIDO2 tokens and typically require that +a PIN be set on the token prior to generation. +Resident keys may be loaded off the token using +.Xr ssh-add 1 . +.It Cm user +A username to be associated with a resident key, +overriding the empty default username. +Specifying a username may be useful when generating multiple resident keys +for the same application name. +.It Cm verify-required +Indicate that this private key should require user verification for +each signature. +Not all FIDO tokens support this option. +Currently PIN authentication is the only supported verification method, +but other methods may be supported in the future. +.It Cm write-attestation Ns = Ns Ar path +May be used at key generation time to record the attestation data +returned from FIDO tokens during key generation. +This information is potentially sensitive. +By default, this information is discarded. +.El +.Pp +When performing signature-related options using the +.Fl Y +flag, the following options are accepted: +.Bl -tag -width Ds +.It Cm hashalg Ns = Ns Ar algorithm +Selects the hash algorithm to use for hashing the message to be signed. +Valid algorithms are +.Dq sha256 +and +.Dq sha512. +The default is +.Dq sha512. +.It Cm print-pubkey +Print the full public key to standard output after signature verification. +.It Cm verify-time Ns = Ns Ar timestamp +Specifies a time to use when validating signatures instead of the current +time. +The time may be specified as a date in YYYYMMDD format or a time +in YYYYMMDDHHMM[SS] format. +.El +.Pp +The +.Fl O +option may be specified multiple times. +.It Fl P Ar passphrase +Provides the (old) passphrase. +.It Fl p +Requests changing the passphrase of a private key file instead of +creating a new private key. +The program will prompt for the file +containing the private key, for the old passphrase, and twice for the +new passphrase. +.It Fl Q +Test whether keys have been revoked in a KRL. +If the +.Fl l +option is also specified then the contents of the KRL will be printed. +.It Fl q +Silence +.Nm ssh-keygen . +.It Fl R Ar hostname | [hostname]:port +Removes all keys belonging to the specified +.Ar hostname +(with optional port number) +from a +.Pa known_hosts +file. +This option is useful to delete hashed hosts (see the +.Fl H +option above). +.It Fl r Ar hostname +Print the SSHFP fingerprint resource record named +.Ar hostname +for the specified public key file. +.It Fl s Ar ca_key +Certify (sign) a public key using the specified CA key. +See the +.Sx CERTIFICATES +section for details. +.Pp +When generating a KRL, +.Fl s +specifies a path to a CA public key file used to revoke certificates directly +by key ID or serial number. +See the +.Sx KEY REVOCATION LISTS +section for details. +.It Fl t Cm dsa | ecdsa | ecdsa-sk | ed25519 | ed25519-sk | rsa +Specifies the type of key to create. +The possible values are +.Dq dsa , +.Dq ecdsa , +.Dq ecdsa-sk , +.Dq ed25519 , +.Dq ed25519-sk , +or +.Dq rsa . +.Pp +This flag may also be used to specify the desired signature type when +signing certificates using an RSA CA key. +The available RSA signature variants are +.Dq ssh-rsa +(SHA1 signatures, not recommended), +.Dq rsa-sha2-256 , +and +.Dq rsa-sha2-512 +(the default). +.It Fl U +When used in combination with +.Fl s , +this option indicates that a CA key resides in a +.Xr ssh-agent 1 . +See the +.Sx CERTIFICATES +section for more information. +.It Fl u +Update a KRL. +When specified with +.Fl k , +keys listed via the command line are added to the existing KRL rather than +a new KRL being created. +.It Fl V Ar validity_interval +Specify a validity interval when signing a certificate. +A validity interval may consist of a single time, indicating that the +certificate is valid beginning now and expiring at that time, or may consist +of two times separated by a colon to indicate an explicit time interval. +.Pp +The start time may be specified as the string +.Dq always +to indicate the certificate has no specified start time, +a date in YYYYMMDD format, a time in YYYYMMDDHHMM[SS] format, +a relative time (to the current time) consisting of a minus sign followed by +an interval in the format described in the +TIME FORMATS section of +.Xr sshd_config 5 . +.Pp +The end time may be specified as a YYYYMMDD date, a YYYYMMDDHHMM[SS] time, +a relative time starting with a plus character or the string +.Dq forever +to indicate that the certificate has no expiry date. +.Pp +For example: +.Dq +52w1d +(valid from now to 52 weeks and one day from now), +.Dq -4w:+4w +(valid from four weeks ago to four weeks from now), +.Dq 20100101123000:20110101123000 +(valid from 12:30 PM, January 1st, 2010 to 12:30 PM, January 1st, 2011), +.Dq -1d:20110101 +(valid from yesterday to midnight, January 1st, 2011), +.Dq -1m:forever +(valid from one minute ago and never expiring). +.It Fl v +Verbose mode. +Causes +.Nm +to print debugging messages about its progress. +This is helpful for debugging moduli generation. +Multiple +.Fl v +options increase the verbosity. +The maximum is 3. +.It Fl w Ar provider +Specifies a path to a library that will be used when creating +FIDO authenticator-hosted keys, overriding the default of using +the internal USB HID support. +.It Fl Y Cm find-principals +Find the principal(s) associated with the public key of a signature, +provided using the +.Fl s +flag in an authorized signers file provided using the +.Fl f +flag. +The format of the allowed signers file is documented in the +.Sx ALLOWED SIGNERS +section below. +If one or more matching principals are found, they are returned on +standard output. +.It Fl Y Cm match-principals +Find principal matching the principal name provided using the +.Fl I +flag in the authorized signers file specified using the +.Fl f +flag. +If one or more matching principals are found, they are returned on +standard output. +.It Fl Y Cm check-novalidate +Checks that a signature generated using +.Nm +.Fl Y Cm sign +has a valid structure. +This does not validate if a signature comes from an authorized signer. +When testing a signature, +.Nm +accepts a message on standard input and a signature namespace using +.Fl n . +A file containing the corresponding signature must also be supplied using the +.Fl s +flag. +Successful testing of the signature is signalled by +.Nm +returning a zero exit status. +.It Fl Y Cm sign +Cryptographically sign a file or some data using a SSH key. +When signing, +.Nm +accepts zero or more files to sign on the command-line - if no files +are specified then +.Nm +will sign data presented on standard input. +Signatures are written to the path of the input file with +.Dq .sig +appended, or to standard output if the message to be signed was read from +standard input. +.Pp +The key used for signing is specified using the +.Fl f +option and may refer to either a private key, or a public key with the private +half available via +.Xr ssh-agent 1 . +An additional signature namespace, used to prevent signature confusion across +different domains of use (e.g. file signing vs email signing) must be provided +via the +.Fl n +flag. +Namespaces are arbitrary strings, and may include: +.Dq file +for file signing, +.Dq email +for email signing. +For custom uses, it is recommended to use names following a +NAMESPACE@YOUR.DOMAIN pattern to generate unambiguous namespaces. +.It Fl Y Cm verify +Request to verify a signature generated using +.Nm +.Fl Y Cm sign +as described above. +When verifying a signature, +.Nm +accepts a message on standard input and a signature namespace using +.Fl n . +A file containing the corresponding signature must also be supplied using the +.Fl s +flag, along with the identity of the signer using +.Fl I +and a list of allowed signers via the +.Fl f +flag. +The format of the allowed signers file is documented in the +.Sx ALLOWED SIGNERS +section below. +A file containing revoked keys can be passed using the +.Fl r +flag. +The revocation file may be a KRL or a one-per-line list of public keys. +Successful verification by an authorized signer is signalled by +.Nm +returning a zero exit status. +.It Fl y +This option will read a private +OpenSSH format file and print an OpenSSH public key to stdout. +.It Fl Z Ar cipher +Specifies the cipher to use for encryption when writing an OpenSSH-format +private key file. +The list of available ciphers may be obtained using +.Qq ssh -Q cipher . +The default is +.Dq aes256-ctr . +.It Fl z Ar serial_number +Specifies a serial number to be embedded in the certificate to distinguish +this certificate from others from the same CA. +If the +.Ar serial_number +is prefixed with a +.Sq + +character, then the serial number will be incremented for each certificate +signed on a single command-line. +The default serial number is zero. +.Pp +When generating a KRL, the +.Fl z +flag is used to specify a KRL version number. +.El +.Sh MODULI GENERATION +.Nm +may be used to generate groups for the Diffie-Hellman Group Exchange +(DH-GEX) protocol. +Generating these groups is a two-step process: first, candidate +primes are generated using a fast, but memory intensive process. +These candidate primes are then tested for suitability (a CPU-intensive +process). +.Pp +Generation of primes is performed using the +.Fl M Cm generate +option. +The desired length of the primes may be specified by the +.Fl O Cm bits +option. +For example: +.Pp +.Dl # ssh-keygen -M generate -O bits=2048 moduli-2048.candidates +.Pp +By default, the search for primes begins at a random point in the +desired length range. +This may be overridden using the +.Fl O Cm start +option, which specifies a different start point (in hex). +.Pp +Once a set of candidates have been generated, they must be screened for +suitability. +This may be performed using the +.Fl M Cm screen +option. +In this mode +.Nm +will read candidates from standard input (or a file specified using the +.Fl f +option). +For example: +.Pp +.Dl # ssh-keygen -M screen -f moduli-2048.candidates moduli-2048 +.Pp +By default, each candidate will be subjected to 100 primality tests. +This may be overridden using the +.Fl O Cm prime-tests +option. +The DH generator value will be chosen automatically for the +prime under consideration. +If a specific generator is desired, it may be requested using the +.Fl O Cm generator +option. +Valid generator values are 2, 3, and 5. +.Pp +Screened DH groups may be installed in +.Pa /etc/moduli . +It is important that this file contains moduli of a range of bit lengths. +.Pp +A number of options are available for moduli generation and screening via the +.Fl O +flag: +.Bl -tag -width Ds +.It Ic lines Ns = Ns Ar number +Exit after screening the specified number of lines while performing DH +candidate screening. +.It Ic start-line Ns = Ns Ar line-number +Start screening at the specified line number while performing DH candidate +screening. +.It Ic checkpoint Ns = Ns Ar filename +Write the last line processed to the specified file while performing DH +candidate screening. +This will be used to skip lines in the input file that have already been +processed if the job is restarted. +.It Ic memory Ns = Ns Ar mbytes +Specify the amount of memory to use (in megabytes) when generating +candidate moduli for DH-GEX. +.It Ic start Ns = Ns Ar hex-value +Specify start point (in hex) when generating candidate moduli for DH-GEX. +.It Ic generator Ns = Ns Ar value +Specify desired generator (in decimal) when testing candidate moduli for DH-GEX. +.El +.Sh CERTIFICATES +.Nm +supports signing of keys to produce certificates that may be used for +user or host authentication. +Certificates consist of a public key, some identity information, zero or +more principal (user or host) names and a set of options that +are signed by a Certification Authority (CA) key. +Clients or servers may then trust only the CA key and verify its signature +on a certificate rather than trusting many user/host keys. +Note that OpenSSH certificates are a different, and much simpler, format to +the X.509 certificates used in +.Xr ssl 8 . +.Pp +.Nm +supports two types of certificates: user and host. +User certificates authenticate users to servers, whereas host certificates +authenticate server hosts to users. +To generate a user certificate: +.Pp +.Dl $ ssh-keygen -s /path/to/ca_key -I key_id /path/to/user_key.pub +.Pp +The resultant certificate will be placed in +.Pa /path/to/user_key-cert.pub . +A host certificate requires the +.Fl h +option: +.Pp +.Dl $ ssh-keygen -s /path/to/ca_key -I key_id -h /path/to/host_key.pub +.Pp +The host certificate will be output to +.Pa /path/to/host_key-cert.pub . +.Pp +It is possible to sign using a CA key stored in a PKCS#11 token by +providing the token library using +.Fl D +and identifying the CA key by providing its public half as an argument +to +.Fl s : +.Pp +.Dl $ ssh-keygen -s ca_key.pub -D libpkcs11.so -I key_id user_key.pub +.Pp +Similarly, it is possible for the CA key to be hosted in a +.Xr ssh-agent 1 . +This is indicated by the +.Fl U +flag and, again, the CA key must be identified by its public half. +.Pp +.Dl $ ssh-keygen -Us ca_key.pub -I key_id user_key.pub +.Pp +In all cases, +.Ar key_id +is a "key identifier" that is logged by the server when the certificate +is used for authentication. +.Pp +Certificates may be limited to be valid for a set of principal (user/host) +names. +By default, generated certificates are valid for all users or hosts. +To generate a certificate for a specified set of principals: +.Pp +.Dl $ ssh-keygen -s ca_key -I key_id -n user1,user2 user_key.pub +.Dl "$ ssh-keygen -s ca_key -I key_id -h -n host.domain host_key.pub" +.Pp +Additional limitations on the validity and use of user certificates may +be specified through certificate options. +A certificate option may disable features of the SSH session, may be +valid only when presented from particular source addresses or may +force the use of a specific command. +.Pp +The options that are valid for user certificates are: +.Pp +.Bl -tag -width Ds -compact +.It Ic clear +Clear all enabled permissions. +This is useful for clearing the default set of permissions so permissions may +be added individually. +.Pp +.It Ic critical : Ns Ar name Ns Op Ns = Ns Ar contents +.It Ic extension : Ns Ar name Ns Op Ns = Ns Ar contents +Includes an arbitrary certificate critical option or extension. +The specified +.Ar name +should include a domain suffix, e.g.\& +.Dq name@example.com . +If +.Ar contents +is specified then it is included as the contents of the extension/option +encoded as a string, otherwise the extension/option is created with no +contents (usually indicating a flag). +Extensions may be ignored by a client or server that does not recognise them, +whereas unknown critical options will cause the certificate to be refused. +.Pp +.It Ic force-command Ns = Ns Ar command +Forces the execution of +.Ar command +instead of any shell or command specified by the user when +the certificate is used for authentication. +.Pp +.It Ic no-agent-forwarding +Disable +.Xr ssh-agent 1 +forwarding (permitted by default). +.Pp +.It Ic no-port-forwarding +Disable port forwarding (permitted by default). +.Pp +.It Ic no-pty +Disable PTY allocation (permitted by default). +.Pp +.It Ic no-user-rc +Disable execution of +.Pa ~/.ssh/rc +by +.Xr sshd 8 +(permitted by default). +.Pp +.It Ic no-x11-forwarding +Disable X11 forwarding (permitted by default). +.Pp +.It Ic permit-agent-forwarding +Allows +.Xr ssh-agent 1 +forwarding. +.Pp +.It Ic permit-port-forwarding +Allows port forwarding. +.Pp +.It Ic permit-pty +Allows PTY allocation. +.Pp +.It Ic permit-user-rc +Allows execution of +.Pa ~/.ssh/rc +by +.Xr sshd 8 . +.Pp +.It Ic permit-X11-forwarding +Allows X11 forwarding. +.Pp +.It Ic no-touch-required +Do not require signatures made using this key include demonstration +of user presence (e.g. by having the user touch the authenticator). +This option only makes sense for the FIDO authenticator algorithms +.Cm ecdsa-sk +and +.Cm ed25519-sk . +.Pp +.It Ic source-address Ns = Ns Ar address_list +Restrict the source addresses from which the certificate is considered valid. +The +.Ar address_list +is a comma-separated list of one or more address/netmask pairs in CIDR +format. +.Pp +.It Ic verify-required +Require signatures made using this key indicate that the user was first +verified. +This option only makes sense for the FIDO authenticator algorithms +.Cm ecdsa-sk +and +.Cm ed25519-sk . +Currently PIN authentication is the only supported verification method, +but other methods may be supported in the future. +.El +.Pp +At present, no standard options are valid for host keys. +.Pp +Finally, certificates may be defined with a validity lifetime. +The +.Fl V +option allows specification of certificate start and end times. +A certificate that is presented at a time outside this range will not be +considered valid. +By default, certificates are valid from the +.Ux +Epoch to the distant future. +.Pp +For certificates to be used for user or host authentication, the CA +public key must be trusted by +.Xr sshd 8 +or +.Xr ssh 1 . +Refer to those manual pages for details. +.Sh KEY REVOCATION LISTS +.Nm +is able to manage OpenSSH format Key Revocation Lists (KRLs). +These binary files specify keys or certificates to be revoked using a +compact format, taking as little as one bit per certificate if they are being +revoked by serial number. +.Pp +KRLs may be generated using the +.Fl k +flag. +This option reads one or more files from the command line and generates a new +KRL. +The files may either contain a KRL specification (see below) or public keys, +listed one per line. +Plain public keys are revoked by listing their hash or contents in the KRL and +certificates revoked by serial number or key ID (if the serial is zero or +not available). +.Pp +Revoking keys using a KRL specification offers explicit control over the +types of record used to revoke keys and may be used to directly revoke +certificates by serial number or key ID without having the complete original +certificate on hand. +A KRL specification consists of lines containing one of the following directives +followed by a colon and some directive-specific information. +.Bl -tag -width Ds +.It Cm serial : Ar serial_number Ns Op - Ns Ar serial_number +Revokes a certificate with the specified serial number. +Serial numbers are 64-bit values, not including zero and may be expressed +in decimal, hex or octal. +If two serial numbers are specified separated by a hyphen, then the range +of serial numbers including and between each is revoked. +The CA key must have been specified on the +.Nm +command line using the +.Fl s +option. +.It Cm id : Ar key_id +Revokes a certificate with the specified key ID string. +The CA key must have been specified on the +.Nm +command line using the +.Fl s +option. +.It Cm key : Ar public_key +Revokes the specified key. +If a certificate is listed, then it is revoked as a plain public key. +.It Cm sha1 : Ar public_key +Revokes the specified key by including its SHA1 hash in the KRL. +.It Cm sha256 : Ar public_key +Revokes the specified key by including its SHA256 hash in the KRL. +KRLs that revoke keys by SHA256 hash are not supported by OpenSSH versions +prior to 7.9. +.It Cm hash : Ar fingerprint +Revokes a key using a fingerprint hash, as obtained from a +.Xr sshd 8 +authentication log message or the +.Nm +.Fl l +flag. +Only SHA256 fingerprints are supported here and resultant KRLs are +not supported by OpenSSH versions prior to 7.9. +.El +.Pp +KRLs may be updated using the +.Fl u +flag in addition to +.Fl k . +When this option is specified, keys listed via the command line are merged into +the KRL, adding to those already there. +.Pp +It is also possible, given a KRL, to test whether it revokes a particular key +(or keys). +The +.Fl Q +flag will query an existing KRL, testing each key specified on the command line. +If any key listed on the command line has been revoked (or an error encountered) +then +.Nm +will exit with a non-zero exit status. +A zero exit status will only be returned if no key was revoked. +.Sh ALLOWED SIGNERS +When verifying signatures, +.Nm +uses a simple list of identities and keys to determine whether a signature +comes from an authorized source. +This "allowed signers" file uses a format patterned after the +AUTHORIZED_KEYS FILE FORMAT described in +.Xr sshd 8 . +Each line of the file contains the following space-separated fields: +principals, options, keytype, base64-encoded key. +Empty lines and lines starting with a +.Ql # +are ignored as comments. +.Pp +The principals field is a pattern-list (see PATTERNS in +.Xr ssh_config 5 ) +consisting of one or more comma-separated USER@DOMAIN identity patterns +that are accepted for signing. +When verifying, the identity presented via the +.Fl I +option must match a principals pattern in order for the corresponding key to be +considered acceptable for verification. +.Pp +The options (if present) consist of comma-separated option specifications. +No spaces are permitted, except within double quotes. +The following option specifications are supported (note that option keywords +are case-insensitive): +.Bl -tag -width Ds +.It Cm cert-authority +Indicates that this key is accepted as a certificate authority (CA) and +that certificates signed by this CA may be accepted for verification. +.It Cm namespaces Ns = Ns "namespace-list" +Specifies a pattern-list of namespaces that are accepted for this key. +If this option is present, the signature namespace embedded in the +signature object and presented on the verification command-line must +match the specified list before the key will be considered acceptable. +.It Cm valid-after Ns = Ns "timestamp" +Indicates that the key is valid for use at or after the specified timestamp, +which may be a date in YYYYMMDD format or a time in YYYYMMDDHHMM[SS] format. +.It Cm valid-before Ns = Ns "timestamp" +Indicates that the key is valid for use at or before the specified timestamp. +.El +.Pp +When verifying signatures made by certificates, the expected principal +name must match both the principals pattern in the allowed signers file and +the principals embedded in the certificate itself. +.Pp +An example allowed signers file: +.Bd -literal -offset 3n +# Comments allowed at start of line +user1@example.com,user2@example.com ssh-rsa AAAAX1... +# A certificate authority, trusted for all principals in a domain. +*@example.com cert-authority ssh-ed25519 AAAB4... +# A key that is accepted only for file signing. +user2@example.com namespaces="file" ssh-ed25519 AAA41... +.Ed +.Sh ENVIRONMENT +.Bl -tag -width Ds +.It Ev SSH_SK_PROVIDER +Specifies a path to a library that will be used when loading any +FIDO authenticator-hosted keys, overriding the

configuration options are described in +.Xr ssh_config 5 . +.Sh AUTHENTICATION +The OpenSSH SSH client supports SSH protocol 2. +.Pp +The methods available for authentication are: +GSSAPI-based authentication, +host-based authentication, +public key authentication, +keyboard-interactive authentication, +and password authentication. +Authentication methods are tried in the order specified above, +though +.Cm PreferredAuthentications +can be used to change the default order. +.Pp +Host-based authentication works as follows: +If the machine the user logs in from is listed in +.Pa /etc/hosts.equiv +or +.Pa /etc/shosts.equiv +on the remote machine, the user is non-root and the user names are +the same on both sides, or if the files +.Pa ~/.rhosts +or +.Pa ~/.shosts +exist in the user's home directory on the +remote machine and contain a line containing the name of the client +machine and the name of the user on that machine, the user is +considered for login. +Additionally, the server +.Em must +be able to verify the client's +host key (see the description of +.Pa /etc/ssh/ssh_known_hosts +and +.Pa ~/.ssh/known_hosts , +below) +for login to be permitted. +This authentication method closes security holes due to IP +spoofing, DNS spoofing, and routing spoofing. +[Note to the administrator: +.Pa /etc/hosts.equiv , +.Pa ~/.rhosts , +and the rlogin/rsh protocol in general, are inherently insecure and should be +disabled if security is desired.] +.Pp +Public key authentication works as follows: +The scheme is based on public-key cryptography, +using cryptosystems +where encryption and decryption are done using separate keys, +and it is unfeasible to derive the decryption key from the encryption key. +The idea is that each user creates a public/private +key pair for authentication purposes. +The server knows the public key, and only the user knows the private key. +.Nm +implements public key authentication protocol automatically, +using one of the DSA, ECDSA, Ed25519 or RSA algorithms. +The HISTORY section of +.Xr ssl 8 +contains a brief discussion of the DSA and RSA algorithms. +.Pp +The file +.Pa ~/.ssh/authorized_keys +lists the public keys that are permitted for logging in. +When the user logs in, the +.Nm +program tells the server which key pair it would like to use for +authentication. +The client proves that it has access to the private key +and the server checks that the corresponding public key +is authorized to accept the account. +.Pp +The server may inform the client of errors that prevented public key +authentication from succeeding after authentication completes using a +different method. +These may be viewed by increasing the +.Cm LogLevel +to +.Cm DEBUG +or higher (e.g. by using the +.Fl v +flag). +.Pp +The user creates their key pair by running +.Xr ssh-keygen 1 . +This stores the private key in +.Pa ~/.ssh/id_dsa +(DSA), +.Pa ~/.ssh/id_ecdsa +(ECDSA), +.Pa ~/.ssh/id_ecdsa_sk +(authenticator-hosted ECDSA), +.Pa ~/.ssh/id_ed25519 +(Ed25519), +.Pa ~/.ssh/id_ed25519_sk +(authenticator-hosted Ed25519), +or +.Pa ~/.ssh/id_rsa +(RSA) +and stores the public key in +.Pa ~/.ssh/id_dsa.pub +(DSA), +.Pa ~/.ssh/id_ecdsa.pub +(ECDSA), +.Pa ~/.ssh/id_ecdsa_sk.pub +(authenticator-hosted ECDSA), +.Pa ~/.ssh/id_ed25519.pub +(Ed25519), +.Pa ~/.ssh/id_ed25519_sk.pub +(authenticator-hosted Ed25519), +or +.Pa ~/.ssh/id_rsa.pub +(RSA) +in the user's home directory. +The user should then copy the public key +to +.Pa ~/.ssh/authorized_keys +in their home directory on the remote machine. +The +.Pa authorized_keys +file corresponds to the conventional +.Pa ~/.rhosts +file, and has one key +per line, though the lines can be very long. +After this, the user can log in without giving the password. +.Pp +A variation on public key authentication +is available in the form of certificate authentication: +instead of a set of public/private keys, +signed certificates are used. +This has the advantage that a single trusted certification authority +can be used in place of many public/private keys. +See the CERTIFICATES section of +.Xr ssh-keygen 1 +for more information. +.Pp +The most convenient way to use public key or certificate authentication +may be with an authentication agent. +See +.Xr ssh-agent 1 +and (optionally) the +.Cm AddKeysToAgent +directive in +.Xr ssh_config 5 +for more information. +.Pp +Keyboard-interactive authentication works as follows: +The server sends an arbitrary +.Qq challenge +text and prompts for a response, possibly multiple times. +Examples of keyboard-interactive authentication include +.Bx +Authentication (see +.Xr login.conf 5 ) +and PAM (some +.Pf non- Ox +systems). +.Pp +Finally, if other authentication methods fail, +.Nm +prompts the user for a password. +The password is sent to the remote +host for checking; however, since all communications are encrypted, +the password cannot be seen by someone listening on the network. +.Pp +.Nm +automatically maintains and checks a database containing +identification for all hosts it has ever been used with. +Host keys are stored in +.Pa ~/.ssh/known_hosts +in the user's home directory. +Additionally, the file +.Pa /etc/ssh/ssh_known_hosts +is automatically checked for known hosts. +Any new hosts are automatically added to the user's file. +If a host's identification ever changes, +.Nm +warns about this and disables password authentication to prevent +server spoofing or man-in-the-middle attacks, +which could otherwise be used to circumvent the encryption. +The +.Cm StrictHostKeyChecking +option can be used to control logins to machines whose +host key is not known or has changed. +.Pp +When the user's identity has been accepted by the server, the server +either executes the given command in a non-interactive session or, +if no command has been specified, logs into the machine and gives +the user a normal shell as an interactive session. +All communication with +the remote command or shell will be automatically encrypted. +.Pp +If an interactive session is requested, +.Nm +by default will only request a pseudo-terminal (pty) for interactive +sessions when the client has one. +The flags +.Fl T +and +.Fl t +can be used to override this behaviour. +.Pp +If a pseudo-terminal has been allocated, the +user may use the escape characters noted below. +.Pp +If no pseudo-terminal has been allocated, +the session is transparent and can be used to reliably transfer binary data. +On most systems, setting the escape character to +.Dq none +will also make the session transparent even if a tty is used. +.Pp +The session terminates when the command or shell on the remote +machine exits and all X11 and TCP connections have been closed. +.Sh ESCAPE CHARACTERS +When a pseudo-terminal has been requested, +.Nm +supports a number of functions through the use of an escape character. +.Pp +A single tilde character can be sent as +.Ic ~~ +or by following the tilde by a character other than those described below. +The escape character must always follow a newline to be interpreted as +special. +The escape character can be changed in configuration files using the +.Cm EscapeChar +configuration directive or on the command line by the +.Fl e +option. +.Pp +The supported escapes (assuming the default +.Ql ~ ) +are: +.Bl -tag -width Ds +.It Cm ~. +Disconnect. +.It Cm ~^Z +Background +.Nm . +.It Cm ~# +List forwarded connections. +.It Cm ~& +Background +.Nm +at logout when waiting for forwarded connection / X11 sessions to terminate. +.It Cm ~? +Display a list of escape characters. +.It Cm ~B +Send a BREAK to the remote system +(only useful if the peer supports it). +.It Cm ~C +Open command line. +Currently this allows the addition of port forwardings using the +.Fl L , +.Fl R +and +.Fl D +options (see above). +It also allows the cancellation of existing port-forwardings +with +.Sm off +.Fl KL Oo Ar bind_address : Oc Ar port +.Sm on +for local, +.Sm off +.Fl KR Oo Ar bind_address : Oc Ar port +.Sm on +for remote and +.Sm off +.Fl KD Oo Ar bind_address : Oc Ar port +.Sm on +for dynamic

+option. +.It Cm ~R +Request rekeying of the connection +(only useful if the peer supports it). +.It Cm ~V +Decrease the verbosity +.Pq Ic LogLevel +when errors are being written to stderr. +.It Cm ~v +Increase the verbosity +.Pq Ic LogLevel +when errors are being written to stderr. +.El +.Sh TCP FORWARDING +Forwarding of arbitrary TCP connections over a secure channel +can be specified either on the command line or in a configuration file. +One possible application of TCP forwarding is a secure connection to a +mail server; another is going through firewalls. +.Pp +In the example below, we look at encrypting communication for an IRC client, +even though the IRC server it connects to does not directly +support encrypted communication. +This works as follows: +the user connects to the remote host using +.Nm , +specifying the ports to be used to forward the connection. +After that it is possible to start the program locally, +and +.Nm +will encrypt and forward the connection to the remote server. +.Pp +The following example tunnels an IRC session from the client +to an IRC server at +.Dq server.example.com , +joining channel +.Dq #users , +nickname +.Dq pinky , +using the standard IRC port, 6667: +.Bd -literal -offset 4n +$ ssh -f -L 6667:localhost:6667 server.example.com sleep 10 +$ irc -c '#users' pinky IRC/127.0.0.1 +.Ed +.Pp +The +.Fl f +option backgrounds +.Nm +and the remote command +.Dq sleep 10 +is specified to allow an amount of time +(10 seconds, in the example) +to start the program which is going to use the tunnel. +If no connections are made within the time specified, +.Nm +will exit. +.Sh X11 FORWARDING +If the +.Cm ForwardX11 +variable is set to +.Dq yes +(or see the description of the +.Fl X , +.Fl x , +and +.Fl Y +options above) +and the user is using X11 (the +.Ev DISPLAY +environment variable is set), the connection to the X11 display is +automatically forwarded to the remote side in such a way that any X11 +programs started from the shell (or command) will go through the +encrypted channel, and the connection to the real X server will be made +from the local machine. +The user should not manually set +.Ev DISPLAY . +Forwarding of X11 connections can be +configured on the command line or in configuration files. +.Pp +The +.Ev DISPLAY +value set by +.Nm +will point to the server machine, but with a display number greater than zero. +This is normal, and happens because +.Nm +creates a +.Dq proxy +X server on the server machine for forwarding the +connections over the encrypted channel. +.Pp +.Nm +will also automatically set up Xauthority data on the server machine. +For this purpose, it will generate a random authorization cookie, +store it in Xauthority on the server, and verify that any forwarded +connections carry this cookie and replace it by the real cookie when +the connection is opened. +The real authentication cookie is never +sent to the server machine (and no cookies are sent in the plain). +.Pp +If the +.Cm ForwardAgent +variable is set to +.Dq yes +(or see the description of the +.Fl A +and +.Fl a +options above) and +the user is using an authentication agent, the connection to the agent +is automatically forwarded to the remote side. +.Sh VERIFYING HOST KEYS +When connecting to a server for the first time, +a fingerprint of the server's public key is presented to the user +(unless the option +.Cm StrictHostKeyChecking +has been disabled). +Fingerprints can be determined using +.Xr ssh-keygen 1 : +.Pp +.Dl $ ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key +.Pp +If the fingerprint is already known, it can be matched +and the key can be accepted or rejected. +If only legacy (MD5) fingerprints for the server are available, the +.Xr ssh-keygen 1 +.Fl E +option may be used to downgrade the fingerprint algorithm to match. +.Pp +Because of the difficulty of comparing host keys +just by looking at fingerprint strings, +there is also support to compare host keys visually, +using +.Em random art . +By setting the +.Cm VisualHostKey +option to +.Dq yes , +a small ASCII graphic gets displayed on every login to a server, no matter +if the session itself is interactive or not. +By learning the pattern a known server produces, a user can easily +find out that the host key has changed when a completely different pattern +is displayed. +Because these patterns are not unambiguous however, a pattern that looks +similar to the pattern remembered only gives a good probability that the +host key is the same, not guaranteed proof. +.Pp +To get a listing of the fingerprints along with their random art for +all known hosts, the following command line can be used: +.Pp +.Dl $ ssh-keygen -lv -f ~/.ssh/known_hosts +.Pp +If the fingerprint is unknown, +an alternative method of verification is available: +SSH fingerprints verified by DNS. +An additional resource record (RR), +SSHFP, +is added to a zonefile +and the connecting client is able to match the fingerprint +with that of the key presented. +.Pp +In this example, we are connecting a client to a server, +.Dq host.example.com . +The SSHFP resource records should first be added to the zonefile for +host.example.com: +.Bd -literal -offset indent +$ ssh-keygen -r host.example.com. +.Ed +.Pp +The output lines will have to be added to the zonefile. +To check that the zone is answering fingerprint queries: +.Pp +.Dl $ dig -t SSHFP host.example.com +.Pp +Finally the client connects: +.Bd -literal -offset indent +$ ssh -o "VerifyHostKeyDNS ask" host.example.com +[...] +Matching host key fingerprint found in DNS. +Are you sure you want to continue connecting (yes/no)? +.Ed +.Pp +See the +.Cm VerifyHostKeyDNS +option in +.Xr ssh_config 5 +for more information. +.Sh SSH-BASED VIRTUAL PRIVATE NETWORKS +.Nm +contains support for Virtual Private Network (VPN) tunnelling +using the +.Xr tun 4 +network pseudo-device, +allowing two networks to be joined securely. +The +.Xr sshd_config 5 +configuration option +.Cm PermitTunnel +controls whether the server supports this, +and at what level (layer 2 or 3 traffic). +.Pp +The following example would connect client network 10.0.50.0/24 +with remote network 10.0.99.0/24 using a point-to-point connection +from 10.1.1.1 to 10.1.1.2, +provided that the SSH server running on the gateway to the remote network, +at 192.168.1.15, allows it. +.Pp +On the client: +.Bd -literal -offset indent +# ssh -f -w 0:1 192.168.1.15 true +# ifconfig tun0 10.1.1.1 10.1.1.2 netmask 255.255.255.252 +# route add 10.0.99.0/24 10.1.1.2 +.Ed +.Pp +On the server: +.Bd -literal -offset indent +# ifconfig tun1 10.1.1.2 10.1.1.1 netmask 255.255.255.252 +# route add 10.0.50.0/24 10.1.1.1 +.Ed +.Pp +Client access may be more finely tuned via the +.Pa /root/.ssh/authorized_keys +file (see below) and the +.Cm PermitRootLogin +server option. +The following entry would permit connections on +.Xr tun 4 +device 1 from user +.Dq jane +and on tun device 2 from user +.Dq john , +if +.Cm PermitRootLogin +is set to +.Dq forced-commands-only : +.Bd -literal -offset 2n +tunnel="1",command="sh /etc/netstart tun1" ssh-rsa ... jane +tunnel="2",command="sh /etc/netstart tun2" ssh-rsa ... john +.Ed +.Pp +Since an SSH-based setup entails a fair amount of overhead, +it may be more suited to temporary setups, +such as for wireless VPNs. +More permanent VPNs are better provided by tools such as +.Xr ipsecctl 8 +and +.Xr isakmpd 8 . +.Sh ENVIRONMENT +.Nm +will normally set the following environment variables: +.Bl -tag -width "SSH_ORIGINAL_COMMAND" +.It Ev DISPLAY +The +.Ev DISPLAY +variable indicates the location of the X11 server. +It is automatically set by +.Nm +to point to a value of the form +.Dq hostname:n , +where

+obtains configuration data from the following sources in +the following order: +.Pp +.Bl -enum -offset indent -compact +.It +command-line options +.It +user's configuration file +.Pq Pa ~/.ssh/config +.It +system-wide configuration file +.Pq Pa /etc/ssh/ssh_config +.El +.Pp +For each parameter, the first obtained value +will be used. +The configuration files contain sections separated by +.Cm Host +specifications, and that section is only applied for hosts that +match one of the patterns given in the specification. +The matched host name is usually the one given on the command line +(see the +.Cm CanonicalizeHostname +option for exceptions). +.Pp +Since the first obtained value for each parameter is used, more +host-specific declarations should be given near the beginning of the +file, and general defaults at the end. +.Pp +The file contains keyword-argument pairs, one per line. +Lines starting with +.Ql # +and empty lines are interpreted as comments. +Arguments may optionally be enclosed in double quotes +.Pq \&" +in order to represent arguments containing spaces. +Configuration options may be separated by whitespace or +optional whitespace and exactly one +.Ql = ; +the latter format is useful to avoid the need to quote whitespace +when specifying configuration options using the +.Nm ssh , +.Nm scp , +and +.Nm sftp +.Fl o +option. +.Pp +The possible +keywords and their meanings are as follows (note that +keywords are case-insensitive and arguments are case-sensitive): +.Bl -tag -width Ds +.It Cm Host +Restricts the following declarations (up to the next +.Cm Host +or +.Cm Match +keyword) to be only for those hosts that match one of the patterns +given after the keyword. +If more than one pattern is provided, they should be separated by whitespace. +A single +.Ql * +as a pattern can be used to provide global +defaults for all hosts. +The host is usually the +.Ar hostname +argument given on the command line +(see the +.Cm CanonicalizeHostname +keyword for exceptions). +.Pp +A pattern entry may be negated by prefixing it with an exclamation mark +.Pq Sq !\& . +If a negated entry is matched, then the +.Cm Host +entry is ignored, regardless of whether any other patterns on the line +match. +Negated matches are therefore useful to provide exceptions for wildcard +matches. +.Pp +See +.Sx PATTERNS +for more information on patterns. +.It Cm Match +Restricts the following declarations (up to the next +.Cm Host +or +.Cm Match +keyword) to be used only when the conditions following the +.Cm Match +keyword are satisfied. +Match conditions are specified using one or more criteria +or the single token +.Cm all +which always matches. +The available criteria keywords are: +.Cm canonical , +.Cm final , +.Cm exec , +.Cm host , +.Cm originalhost , +.Cm user , +and +.Cm localuser . +The +.Cm all +criteria must appear alone or immediately after +.Cm canonical +or +.Cm final . +Other criteria may be combined arbitrarily. +All criteria but +.Cm all , +.Cm canonical , +and +.Cm final +require an argument. +Criteria may be negated by prepending an exclamation mark +.Pq Sq !\& . +.Pp +The +.Cm canonical +keyword matches only when the configuration file is being re-parsed +after hostname canonicalization (see the +.Cm CanonicalizeHostname +option). +This may be useful to specify conditions that work with canonical host +names only. +.Pp +The +.Cm final +keyword requests that the configuration be re-parsed (regardless of whether +.Cm CanonicalizeHostname +is enabled), and matches only during this final pass. +If +.Cm CanonicalizeHostname +is enabled, then +.Cm canonical +and +.Cm final +match during the same pass. +.Pp +The +.Cm exec +keyword executes the specified command under the user's shell. +If the command returns a zero exit status then the condition is considered true. +Commands containing whitespace characters must be quoted. +Arguments to +.Cm exec +accept the tokens described in the +.Sx TOKENS +section. +.Pp +The other keywords' criteria must be single entries or comma-separated +lists and may use the wildcard and negation operators described in the +.Sx PATTERNS +section. +The criteria for the +.Cm host +keyword are matched against the target hostname, after any substitution +by the +.Cm Hostname +or +.Cm CanonicalizeHostname +options. +The +.Cm originalhost +keyword matches against the hostname as it was specified on the command-line. +The +.Cm user +keyword matches against the target username on the remote host. +The +.Cm localuser +keyword matches against the name of the local user running +.Xr ssh 1 +(this keyword may be useful in system-wide +.Nm +files). +.It Cm AddKeysToAgent +Specifies whether keys should be automatically added to a running +.Xr ssh-agent 1 . +If this option is set to +.Cm yes +and a key is loaded from a file, the key and its passphrase are added to +the agent with the default lifetime, as if by +.Xr ssh-add 1 . +If this option is set to +.Cm ask , +.Xr ssh 1 +will require confirmation using the +.Ev SSH_ASKPASS +program before adding a key (see +.Xr ssh-add 1 +for details). +If this option is set to +.Cm confirm , +each use of the key must be confirmed, as if the +.Fl c +option was specified to +.Xr ssh-add 1 . +If this option is set to +.Cm no , +no keys are added to the agent. +Alternately, this option may be specified as a time interval +using the format described in the +.Sx TIME FORMATS +section of +.Xr sshd_config 5 +to specify the key's lifetime in +.Xr ssh-agent 1 , +after which it will automatically be removed. +The argument must be +.Cm no +(the default), +.Cm yes , +.Cm confirm +(optionally followed by a time interval), +.Cm ask +or a time interval. +.It Cm AddressFamily +Specifies which address family to use when connecting. +Valid arguments are +.Cm any +(the default), +.Cm inet +(use IPv4 only), or +.Cm inet6 +(use IPv6 only). +.It Cm BatchMode +If set to +.Cm yes , +user interaction such as password prompts and host key confirmation requests +will be disabled. +This option is useful in scripts and other batch jobs where no user +is present to interact with +.Xr ssh 1 . +The argument must be +.Cm yes +or +.Cm no +(the default). +.It Cm BindAddress +Use the specified address on the local machine as the source address of +the connection. +Only useful on systems with more than one address. +.It Cm BindInterface +Use the address of the specified interface on the local machine as the +source address of the connection. +.It Cm CanonicalDomains +When +.Cm CanonicalizeHostname +is enabled, this option specifies the list of domain suffixes in which to +search for the specified destination host. +.It Cm CanonicalizeFallbackLocal +Specifies whether to fail with an error when hostname canonicalization fails. +The default, +.Cm yes , +will attempt to look up the unqualified hostname using the system resolver's +search rules. +A value of +.Cm no +will cause +.Xr ssh 1 +to fail instantly if +.Cm CanonicalizeHostname +is enabled and the target hostname cannot be found in any of the domains +specified by +.Cm CanonicalDomains . +.It Cm CanonicalizeHostname +Controls whether explicit hostname canonicalization is performed. +The default, +.Cm no , +is not to perform any name rewriting and let the system resolver handle all +hostname lookups. +If set to +.Cm yes +then, for connections that do not use a +.Cm ProxyCommand +or +.Cm ProxyJump , +.Xr ssh 1 +will attempt to canonicalize the hostname specified on the command line +using the +.Cm CanonicalDomains +suffixes and +.Cm CanonicalizePermittedCNAMEs +rules. +If +.Cm CanonicalizeHostname +is set to +.Cm always , +then canonicalization is applied to proxied connections too. +.Pp +If this option is enabled, then the configuration files are processed +again using the new target name to pick up any new configuration in matching +.Cm Host +and +.Cm Match +stanzas. +A value of +.Cm none +disables the use of a +.Cm ProxyJump +host. +.It Cm CanonicalizeMaxDots +Specifies the maximum number of dot characters in a hostname before +canonicalization is disabled. +The default, 1, +allows a single dot (i.e. hostname.subdomain). +.It Cm CanonicalizePermittedCNAMEs +Specifies rules to determine whether CNAMEs should be followed when +canonicalizing hostnames. +The rules consist of one or more arguments of +.Ar source_domain_list : Ns Ar target_domain_list , +where +.Ar source_domain_list +is a pattern-list of domains that may follow CNAMEs in canonicalization, +and +.Ar target_domain_list +is a pattern-list of domains that they may resolve to. +.Pp +For example, +.Qq *.a.example.com:*.b.example.com,*.c.example.com +will allow hostnames matching +.Qq *.a.example.com +to be canonicalized to names in the +.Qq *.b.example.com +or +.Qq *.c.example.com +domains. +.Pp +A single argument of +.Qq none +causes no CNAMEs to be considered for canonicalization. +This is the default behaviour. +.It Cm CASignatureAlgorithms +Specifies which algorithms are allowed for signing of certificates +by certificate authorities (CAs). +The default is: +.Bd -literal -offset indent +ssh-ed25519,ecdsa-sha2-nistp256, +ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, +sk-ssh-ed25519@openssh.com, +sk-ecdsa-sha2-nistp256@openssh.com, +rsa-sha2-512,rsa-sha2-256 +.Ed +.Pp +If the specified list begins with a +.Sq + +character, then the specified algorithms will be appended to the default set +instead of replacing them. +If the specified list begins with a +.Sq - +character, then the specified algorithms (including wildcards) will be removed +from the default set instead of replacing them. +.Pp +.Xr ssh 1 +will not accept host certificates signed using algorithms other than those +specified. +.It Cm CertificateFile +Specifies a file from which the user's certificate is read. +A corresponding private key must be provided separately in order +to use this certificate either +from an +.Cm IdentityFile +directive or +.Fl i +flag to +.Xr ssh 1 , +via +.Xr ssh-agent 1 , +or via a +.Cm PKCS11Provider +or +.Cm SecurityKeyProvider . +.Pp +Arguments to +.Cm CertificateFile +may use the tilde syntax to refer to a user's home directory, +the tokens described in the +.Sx TOKENS +section and environment variables as described in the +.Sx ENVIRONMENT VARIABLES +section. +.Pp +It is possible to have multiple certificate files specified in +configuration files; these certificates will be tried in sequence. +Multiple +.Cm CertificateFile +directives will add to the list of certificates used for +authentication. +.It Cm CheckHostIP +If set to +.Cm yes , +.Xr ssh 1 +will additionally check the host IP address in the +.Pa known_hosts +file. +This allows it to detect if a host key changed due to DNS spoofing +and will add addresses of destination hosts to +.Pa ~/.ssh/known_hosts +in the process, regardless of the setting of +.Cm StrictHostKeyChecking . +If the option is set to +.Cm no +(the default), +the check will not be executed. +.It Cm Ciphers +Specifies the ciphers allowed and their order of preference. +Multiple ciphers must be comma-separated. +If the specified list begins with a +.Sq + +character, then the specified ciphers will be appended to the default set +instead of replacing them. +If the specified list begins with a +.Sq - +character, then the specified ciphers (including wildcards) will be removed +from the default set instead of replacing them. +If the specified list begins with a +.Sq ^ +character, then the specified ciphers will be placed at the head of the +default set. +.Pp +The supported ciphers are: +.Bd -literal -offset indent +3des-cbc +aes128-cbc +aes192-cbc +aes256-cbc +aes128-ctr +aes192-ctr +aes256-ctr +aes128-gcm@openssh.com +aes256-gcm@openssh.com +chacha20-poly1305@openssh.com +.Ed +.Pp +The default is: +.Bd -literal -offset indent +chacha20-poly1305@openssh.com, +aes128-ctr,aes192-ctr,aes256-ctr, +aes128-gcm@openssh.com,aes256-gcm@openssh.com +.Ed +.Pp +The list of available ciphers may also be obtained using +.Qq ssh -Q cipher . +.It Cm ClearAllForwardings +Specifies that all local, remote, and dynamic port forwardings +specified in the configuration files or on the command line be +cleared. +This option is primarily useful when used from the +.Xr ssh 1 +command line to clear port forwardings set in +configuration files, and is automatically set by +.Xr scp 1 +and +.Xr sftp 1 . +The argument must be +.Cm yes +or +.Cm no +(the default). +.It Cm Compression +Specifies whether to use compression. +The argument must be +.Cm yes +or +.Cm no +(the default). +.It Cm ConnectionAttempts +Specifies the number of tries (one per second) to make before exiting. +The argument must be an integer. +This may be useful in scripts if the connection sometimes fails. +The default is 1. +.It Cm ConnectTimeout +Specifies the timeout (in seconds) used when connecting to the +SSH server, instead of using the default system TCP timeout. +This timeout is applied both to establishing the connection and to performing +the initial SSH protocol handshake and key exchange. +.It Cm ControlMaster +Enables the sharing of multiple sessions over a single network connection. +When set to +.Cm yes , +.Xr ssh 1 +will listen for connections on a control socket specified using the +.Cm ControlPath +argument. +Additional sessions can connect to this socket using the same +.Cm ControlPath +with +.Cm ControlMaster +set to +.Cm no +(the default). +These sessions will try to reuse the master instance's network connection +rather than initiating new ones, but will fall back to connecting normally +if the control socket does not exist, or is not listening. +.Pp +Setting this to +.Cm ask +will cause +.Xr ssh 1 +to listen for control connections, but require confirmation using +.Xr ssh-askpass 1 . +If the +.Cm ControlPath +cannot be opened, +.Xr ssh 1 +will continue without connecting to a master instance. +.Pp +X11 and +.Xr ssh-agent 1 +forwarding is supported over these multiplexed connections, however the +display and agent forwarded will be the one belonging to the master +connection i.e. it is not possible to forward multiple displays or agents. +.Pp +Two additional options allow for opportunistic multiplexing: try to use a +master connection but fall back to creating a new one if one does not already +exist. +These options are: +.Cm auto +and +.Cm autoask . +The latter requires confirmation like the +.Cm ask +option. +.It Cm ControlPath +Specify the path to the control socket used for connection sharing as described +in the +.Cm ControlMaster +section above or the string +.Cm none +to disable connection sharing. +Arguments to +.Cm ControlPath +may use the tilde syntax to refer to a user's home directory, +the tokens described in the +.Sx TOKENS +section and environment variables as described in the +.Sx ENVIRONMENT VARIABLES +section. +It is recommended that any +.Cm ControlPath +used for opportunistic connection sharing include +at least %h, %p, and %r (or alternatively %C) and be placed in a directory +that is not writable by other users. +This ensures that shared connections are uniquely identified. +.It Cm ControlPersist +When used in conjunction with +.Cm ControlMaster , +specifies that the master connection should remain open +in the background (waiting for future client connections) +after the initial client connection has been closed. +If set to +.Cm no +(the default), +then the master connection will not be placed into the background, +and will close as soon as the initial client connection is closed. +If set to +.Cm yes +or 0, +then the master connection will remain in the background indefinitely +(until killed or closed via a mechanism such as the +.Qq ssh -O exit ) . +If set to a time in seconds, or a time in any of the formats documented in +.Xr sshd_config 5 , +then the backgrounded master connection will automatically terminate +after it has remained idle (with no client connections) for the +specified time. +.It Cm DynamicForward +Specifies that a TCP port on the local machine be forwarded +over the secure channel, and the application +protocol is then used to determine where to connect to from the +remote machine. +.Pp +The argument must be +.Sm off +.Oo Ar bind_address : Oc Ar port . +.Sm on +IPv6 addresses can be specified by enclosing addresses in square brackets. +By default, the local port is bound in accordance with the +.Cm GatewayPorts +setting. +However, an explicit +.Ar bind_address +may be used to bind the connection to a specific address. +The +.Ar bind_address +of +.Cm localhost +indicates that the listening port be bound for local use only, while an +empty address or +.Sq * +indicates that the port should be available from all interfaces. +.Pp +Currently the SOCKS4 and SOCKS5 protocols are supported, and +.Xr ssh 1 +will act as a SOCKS server. +Multiple forwardings may be specified, and +additional forwardings can be given on the command line. +Only the superuser can forward privileged ports. +.It Cm EnableSSHKeysign +Setting this option to +.Cm yes +in the global client configuration file +.Pa /etc/ssh/ssh_config +enables the use of the helper program +.Xr ssh-keysign 8 +during +.Cm HostbasedAuthentication . +The argument must be +.Cm yes +or +.Cm no +(the default). +This option should be placed in the non-hostspecific section. +See +.Xr ssh-keysign 8 +for more information. +.It Cm EscapeChar +Sets the escape character (default: +.Ql ~ ) . +The escape character can also +be set on the command line. +The argument should be a single character, +.Ql ^ +followed by a letter, or +.Cm none +to disable the escape +character entirely (making the connection transparent for binary +data). +.It Cm ExitOnForwardFailure +Specifies whether +.Xr ssh 1 +should terminate the connection if it cannot set up all requested +dynamic, tunnel, local, and remote port forwardings, (e.g.\& +if either end is unable to bind and listen on a specified port). +Note that +.Cm ExitOnForwardFailure +does not apply to connections made over port forwardings and will not, +for example, cause +.Xr ssh 1 +to exit if TCP connections to the ultimate forwarding destination fail. +The argument must be +.Cm yes +or +.Cm no +(the default). +.It Cm FingerprintHash +Specifies the hash algorithm used when displaying key fingerprints. +Valid options are: +.Cm md5 +and +.Cm sha256 +(the default). +.It Cm ForkAfterAuthentication +Requests +.Nm ssh +to go to background just before command execution. +This is useful if +.Nm ssh +is going to ask for passwords or passphrases, but the user +wants it in the background. +This implies the +.Cm StdinNull +configuration option being set to +.Dq yes . +The recommended way to start X11 programs at a remote site is with +something like +.Ic ssh -f host xterm , +which is the same as +.Ic ssh host xterm +if the +.Cm ForkAfterAuthentication +configuration option is set to +.Dq yes . +.Pp +If the +.Cm ExitOnForwardFailure +configuration option is set to +.Dq yes , +then a client started with the +.Cm ForkAfterAuthentication +configuration option being set to +.Dq yes +will wait for all remote port forwards to be successfully established +before placing itself in the background. +The argument to this keyword must be +.Cm yes +(same as the +.Fl f +option) or +.Cm no +(the default). +.It Cm ForwardAgent +Specifies whether the connection to the authentication agent (if any) +will be forwarded to the remote machine. +The argument may be +.Cm yes , +.Cm no +(the default), +an explicit path to an agent socket or the name of an environment variable +(beginning with +.Sq $ ) +in which to find the path. +.Pp +Agent forwarding should be enabled with caution. +Users with the ability to bypass file permissions on the remote host +(for the agent's Unix-domain socket) +can access the local agent through the forwarded connection. +An attacker cannot obtain key material from the agent, +however they can perform operations on the keys that enable them to +authenticate using the identities loaded into the agent. +.It Cm ForwardX11 +Specifies whether X11 connections will be automatically redirected +over the secure channel and +.Ev DISPLAY +set. +The argument must be +.Cm yes +or +.Cm no +(the default). +.Pp +X11 forwarding should be enabled with caution. +Users with the ability to bypass file permissions on the remote host +(for the user's X11 authorization database) +can access the local X11 display through the forwarded connection. +An attacker may then be able to perform activities such as keystroke monitoring +if the +.Cm ForwardX11Trusted +option is also enabled. +.It Cm ForwardX11Timeout +Specify a timeout for untrusted X11 forwarding +using the format described in the +.Sx TIME FORMATS +section of +.Xr sshd_config 5 . +X11 connections received by +.Xr ssh 1 +after this time will be refused. +Setting +.Cm ForwardX11Timeout +to zero will disable the timeout and permit X11 forwarding for the life +of the connection. +The default is to disable untrusted X11 forwarding after twenty minutes has +elapsed. +.It Cm ForwardX11Trusted +If this option is set to +.Cm yes , +remote X11 clients will have full access to the original X11 display. +.Pp +If this option

exits abnormally or returns a non-zero exit status then the +connection is terminated. +.It Cm LocalCommand +Specifies a command to execute on the local machine after successfully +connecting to the server. +The command string extends to the end of the line, and is executed with +the user's shell. +Arguments to +.Cm LocalCommand +accept the tokens described in the +.Sx TOKENS +section. +.Pp +The command is run synchronously and does not have access to the +session of the +.Xr ssh 1 +that spawned it. +It should not be used for interactive commands. +.Pp +This directive is ignored unless +.Cm

+However, an explicit +.Ar bind_address +may be used to bind the connection to a specific address. +The +.Ar bind_address +of +.Cm localhost +indicates that the listening port be bound for local use only, while an +empty address or +.Sq * +indicates that the port should be available from all interfaces. +Unix domain socket paths may use the tokens described in the +.Sx TOKENS +section and

are: +QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. +The default is INFO. +DEBUG and DEBUG1 are equivalent. +DEBUG2 and DEBUG3 each specify higher levels of verbose output. +.It Cm LogVerbose +Specify one or more overrides to LogLevel. +An override consists of a pattern lists that matches the source file, function +and line number to force detailed logging for. +For example, an override pattern of: +.Bd -literal -offset indent +kex.c:*:1000,*:kex_exchange_identification():*,packet.c:* +.Ed +.Pp +would enable detailed logging for line 1000 of +.Pa kex.c ,

+disables this option entirely. +.Pp +Note that this option will compete with the +.Cm ProxyCommand +option - whichever is specified first will prevent later instances of the +other from taking effect. +.Pp +Note also that the configuration for the destination host (either supplied +via the command-line or the configuration file) is not generally applied +to jump hosts. +.Pa ~/.ssh/config

that may pass before the session key is renegotiated. +The first argument is specified in bytes and may have a suffix of +.Sq K , +.Sq M , +or +.Sq G +to indicate Kilobytes, Megabytes, or Gigabytes, respectively. +The default is between +.Sq 1G +and +.Sq 4G , +depending on the cipher. +The optional second value is specified in seconds and may use any of the +units documented in the TIME FORMATS section of +.Xr sshd_config 5 . +The default value for +.Cm RekeyLimit +is +.Cm default none , +which means that rekeying is performed after the cipher's default amount +of data has been sent or received and no time based rekeying is done. +.It Cm RemoteCommand +Specifies a command to execute on the remote machine after successfully +connecting to the server. +The command string extends to the end of the line, and is executed with +the user's shell. +Arguments to +.Cm RemoteCommand +accept the tokens described in the +.Sx TOKENS +section. +.It Cm RemoteForward +Specifies that a TCP port on the remote machine be forwarded over +the secure channel. +The remote port may either be forwarded to a specified host and port +from the local machine, or may act as a SOCKS 4/5 proxy that allows a remote +client to connect to arbitrary destinations from the local machine. +The first argument is the listening specification and may be +.Sm off +.Oo Ar bind_address : Oc Ar port +.Sm on +or, if the remote host supports it, a Unix domain socket path. +If forwarding to a specific destination then the second argument must be +.Ar host : Ns Ar hostport +or a Unix domain socket path, +otherwise if no destination argument is specified then the remote forwarding +will be established as a SOCKS proxy. +When acting as a SOCKS proxy, the destination of the connection can be +restricted by +.Cm PermitRemoteOpen . +.Pp +IPv6 addresses can be specified by enclosing addresses in square brackets. +Multiple forwardings may be specified, and additional +forwardings can be given on the command line. +Privileged ports can be forwarded only when +logging in as root on the remote machine. +Unix domain socket paths may use the tokens described in the +.Sx TOKENS +section and environment variables as described in the +.Sx ENVIRONMENT VARIABLES +section. +.Pp +If the +.Ar port +argument is 0, +the listen port will be dynamically allocated on the server and reported +to the client at run time. +.Pp +If the +.Ar bind_address +is not specified, the default is to only bind to loopback addresses. +If the +.Ar bind_address +is +.Ql * +or an empty string, then the forwarding is requested to listen on all +interfaces. +Specifying a remote +.Ar bind_address +will only succeed if the server's +.Cm GatewayPorts +option is enabled (see +.Xr sshd_config 5 ) . +.It Cm RequestTTY +Specifies whether to request a pseudo-tty for the session. +The argument may be one of: +.Cm no +(never request a TTY), +.Cm yes +(always request a TTY when standard input is a TTY), +.Cm force +(always request a TTY) or +.Cm auto +(request a TTY when opening a login session). +This option mirrors the +.Fl t +and +.Fl T +flags for +.Xr ssh 1 . +.It Cm RevokedHostKeys +Specifies revoked host public keys. +Keys listed in this file will be refused for host authentication. +Note that if this file does not exist or is not readable, +then host authentication will be refused for all hosts. +Keys may be specified as a text file, listing one public key per line, or as +an OpenSSH Key Revocation List (KRL) as generated by +.Xr ssh-keygen 1 . +For more information on KRLs, see the KEY REVOCATION LISTS section in +.Xr ssh-keygen 1 . +.It Cm SecurityKeyProvider +Specifies a path to a library that will be used when loading any +FIDO authenticator-hosted keys, overriding the default of using +the built-in USB HID support. +.Pp +If the specified value begins with a +.Sq $ +character, then it will be treated as an environment variable containing +the path to the library. +.It Cm SendEnv +Specifies what variables from the local +.Xr environ 7 +should be sent to the server. +The server must also support it, and the server must be configured to +accept these environment variables. +Note that the +.Ev TERM +environment variable is always sent whenever a +pseudo-terminal is requested as it is required by the protocol. +Refer to +.Cm AcceptEnv +in +.Xr sshd_config 5 +for how to configure the server. +Variables are specified by name, which may contain wildcard characters. +Multiple environment variables may be separated by whitespace or spread +across multiple +.Cm SendEnv +directives. +.Pp +See +.Sx PATTERNS +for more information on patterns. +.Pp +It is possible to clear previously set +.Cm SendEnv +variable names by prefixing patterns with +.Pa - . +The default is not to send any environment variables. +.It Cm ServerAliveCountMax +Sets the number of server alive messages (see below) which may be +sent without +.Xr ssh 1 +receiving any messages back from the server. +If this threshold is reached while server alive messages are being sent, +ssh will disconnect from the server, terminating the session. +It is important to note that the use of server alive messages is very +different from +.Cm TCPKeepAlive +(below). +The server alive messages are sent through the encrypted channel +and therefore will not be spoofable. +The TCP keepalive option enabled by +.Cm TCPKeepAlive +is spoofable. +The server alive mechanism is valuable when the client or +server depend on knowing when a connection has become unresponsive. +.Pp +The default value is 3. +If, for example, +.Cm ServerAliveInterval +(see below) is set to 15 and +.Cm ServerAliveCountMax +is left at the default, if the server becomes unresponsive, +ssh will disconnect after approximately 45 seconds. +.It Cm ServerAliveInterval +Sets a timeout interval in seconds after which if no data has been received +from the server, +.Xr ssh 1 +will send a message through the encrypted +channel to request a response from the server. +The default +is 0, indicating that these messages will not be sent to the server. +.It Cm SessionType +May be used to either request invocation of a subsystem on the remote system, +or to prevent the execution of a remote command at all. +The latter is useful for just forwarding ports. +The argument to this keyword must be +.Cm none +(same as the +.Fl N +option), +.Cm subsystem +(same as the +.Fl s +option) or +.Cm default +(shell or command execution). +.It Cm SetEnv +Directly specify one or more environment variables and their contents to +be sent to the server. +Similarly to +.Cm SendEnv , +with the exception of the +.Ev TERM +variable, the server must be prepared to accept the environment variable. +.It Cm StdinNull +Redirects stdin from +.Pa /dev/null +(actually, prevents reading from stdin). +Either this or the equivalent +.Fl n +option must be used when +.Nm ssh +is run in the background. +The argument to this

socket file for local or remote +port forwarding. +This option is only used for port forwarding to a Unix-domain socket file. +.Pp +The default value is 0177, which creates a Unix-domain socket file that is +readable and writable only by the owner. +Note that not all operating systems honor the file mode on Unix-domain +socket files. +.It Cm StreamLocalBindUnlink +Specifies whether to remove an existing Unix-domain socket file for local +or remote port forwarding before creating a new one. +If the socket file already exists and +.Cm StreamLocalBindUnlink +is not enabled, +.Nm ssh +will be unable to forward the port to the Unix-domain socket file. +This option is only used for port forwarding to a Unix-domain socket file. +.Pp +The argument must be +.Cm yes +or +.Cm no +(the default). +.It Cm StrictHostKeyChecking +If this flag is set to +.Cm yes , +.Xr ssh 1 +will never automatically add host keys to the +.Pa ~/.ssh/known_hosts +file, and refuses to connect to hosts whose host key has changed. +This provides maximum protection against man-in-the-middle (MITM) attacks, +though it can be annoying when the +.Pa /etc/ssh/ssh_known_hosts +file is poorly maintained or when connections to new hosts are +frequently made. +This option forces the user to manually +add all new hosts. +.Pp +If this flag is set to +.Cm accept-new +then ssh will automatically add new host keys to the user's +.Pa known_hosts +file, but will not permit connections to hosts with +changed host keys. +If this flag is set to +.Cm no +or +.Cm off , +ssh will automatically add new host keys to the user known hosts files +and allow connections to hosts with changed hostkeys to proceed, +subject to some restrictions. +If this flag is set to +.Cm ask +(the default), +new host keys +will be added to the user known host files only after the user +has confirmed that is what they really want to do, and +ssh will refuse to connect to hosts whose host key has changed. +The host keys of +known hosts will be verified automatically in all cases. +.It Cm SyslogFacility +Gives the facility code that is used when logging messages from +.Xr ssh 1 . +The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, +LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. +The default is USER. +.It Cm TCPKeepAlive +Specifies whether the system should send TCP keepalive messages to the +other side. +If they are sent, death of the connection or crash of one +of the machines will be properly noticed. +However, this means that +connections will die if the route is down temporarily, and some people +find it annoying. +.Pp +The default is +.Cm yes +(to send TCP keepalive messages), and the client will notice +if the network goes down or the remote host dies. +This is important in scripts, and many users want it too. +.Pp +To disable TCP keepalive messages, the value should be set to +.Cm no . +See also +.Cm ServerAliveInterval +for protocol-level keepalives. +.It Cm Tunnel +Request +.Xr tun 4 +device forwarding between the client and the server. +The argument must be +.Cm yes , +.Cm point-to-point +(layer 3), +.Cm ethernet +(layer 2), +or +.Cm no +(the default). +Specifying +.Cm yes +requests the default tunnel mode, which is +.Cm point-to-point . +.It Cm TunnelDevice +Specifies the +.Xr tun 4 +devices to open on the client +.Pq Ar local_tun +and the server +.Pq Ar remote_tun . +.Pp +The argument must be +.Sm off +.Ar local_tun Op : Ar remote_tun . +.Sm on +The devices may be specified by numerical ID or the keyword +.Cm any , +which uses the next available tunnel device. +If +.Ar remote_tun +is not specified, it defaults to +.Cm any . +The default is +.Cm any:any . +.It Cm UpdateHostKeys +Specifies whether +.Xr ssh 1 +should accept notifications of additional hostkeys from the server sent +after authentication has completed and add them to +.Cm UserKnownHostsFile . +The argument must be +.Cm yes , +.Cm no +or +.Cm ask . +This option allows learning alternate hostkeys for a server +and supports graceful key rotation by allowing a server to send replacement +public keys before old ones are removed. +.Pp +Additional hostkeys are only accepted if the key used to authenticate the +host was already trusted or explicitly accepted by the user, the host was +authenticated via +.Cm UserKnownHostsFile +(i.e. not +.Cm GlobalKnownHostsFile ) +and the host was authenticated using a plain key and not a certificate. +.Pp +.Cm UpdateHostKeys +is enabled by default if the user has not overridden the default +.Cm UserKnownHostsFile +setting and has not enabled +.Cm VerifyHostKeyDNS , +otherwise +.Cm UpdateHostKeys +will be set to +.Cm no . +.Pp +If +.Cm UpdateHostKeys +is set to +.Cm ask , +then the user is asked to confirm the modifications to the known_hosts file. +Confirmation is currently incompatible with +.Cm ControlPersist , +and will be disabled if it is enabled. +.Pp +Presently, only +.Xr sshd 8 +from OpenSSH 6.8 and greater support the +.Qq hostkeys@openssh.com +protocol extension used to inform the client of all the server's hostkeys. +.It Cm User +Specifies the user to log in as. +This can be useful when a different user name is used on different machines. +This saves the trouble of +having to remember to give the user name on the command line. +.It Cm UserKnownHostsFile +Specifies one or more files to use for the user +host key database, separated by whitespace. +Each filename may use tilde notation to refer to the user's home directory, +the tokens described in the +.Sx TOKENS +section and environment variables as described in the +.Sx ENVIRONMENT VARIABLES +section. +The default is +.Pa ~/.ssh/known_hosts , +.Pa ~/.ssh/known_hosts2 . +.It Cm VerifyHostKeyDNS +Specifies whether to verify the remote key using DNS and SSHFP resource +records. +If this option is set to +.Cm yes , +the client will implicitly trust keys that match a secure fingerprint +from DNS. +Insecure fingerprints will be handled as if this option was set to +.Cm ask . +If this option is set to +.Cm ask , +information on fingerprint match will be displayed, but the user will still +need to confirm new host keys according to the +.Cm StrictHostKeyChecking +option. +The default is +.Cm no . +.Pp +See also +.Sx VERIFYING HOST KEYS +in +.Xr ssh 1 . +.It Cm VisualHostKey +If this flag is set to +.Cm yes , +an ASCII art representation of the remote host key fingerprint is +printed in addition to the fingerprint string at login and +for unknown host keys. +If this flag is set to +.Cm no +(the default), +no fingerprint strings are printed at login and +only the fingerprint string will be printed for unknown host keys. +.It Cm XAuthLocation +Specifies the full pathname of the +.Xr xauth 1 +program. +The default is +.Pa /usr/X11R6/bin/xauth . +.El +.Sh PATTERNS +A +.Em pattern +consists of zero or more non-whitespace characters, +.Sq * +(a wildcard that matches zero or more characters), +or +.Sq ?\& +(a wildcard that matches exactly one character). +For example, to specify a set of declarations for any host in the +.Qq .co.uk +set of domains, +the following pattern could be used: +.Pp +.Dl Host *.co.uk +.Pp +The following pattern +would match any host in the 192.168.0.[0-9] network range: +.Pp +.Dl Host 192.168.0.? +.Pp +A +.Em pattern-list +is a comma-separated list of patterns. +Patterns within pattern-lists may be negated +by preceding them with an exclamation mark +.Pq Sq !\& . +For example, +to allow a key to be used from anywhere within an organization +except from the +.Qq dialup +pool, +the following entry (in authorized_keys) could be used: +.Pp +.Dl from=\&"!*.dialup.example.com,*.example.com\&" +.Pp +Note that a negated match will never produce a positive result by itself. +For example, attempting to match +.Qq host3 +against the following pattern-list will fail: +.Pp +.Dl from=\&"!host1,!host2\&" +.Pp +The solution here is to include a term that will yield a positive match, +such as a wildcard: +.Pp +.Dl from=\&"!host1,!host2,*\&" +.Sh TOKENS +Arguments to some keywords can make use of tokens, +which are expanded at runtime: +.Pp +.Bl -tag -width XXXX -offset indent

Fl u Ar len +.Ek +.Sh DESCRIPTION +.Nm +(OpenSSH Daemon) is the daemon program for +.Xr ssh 1 . +It provides secure encrypted communications between two untrusted hosts +over an insecure network. +.Pp +.Nm +listens for connections from clients. +It is normally started at boot from +.Pa /etc/rc . +It forks a new +daemon for each incoming connection. +The forked daemons handle +key exchange, encryption, authentication, command execution, +and data exchange. +.Pp +.Nm +can be configured using command-line options or a configuration file +(by default +.Xr sshd_config 5 ) ; +command-line options override values specified in the +configuration file. +.Nm +rereads its configuration file when it receives a hangup signal, +.Dv SIGHUP , +by executing itself with the name and options it was started with, e.g.\& +.Pa /usr/sbin/sshd . +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl 4 +Forces +.Nm +to use IPv4 addresses only. +.It Fl 6 +Forces +.Nm +to use IPv6 addresses only. +.It Fl C Ar connection_spec +Specify the connection parameters to use for the +.Fl T +extended test mode. +If provided, any +.Cm Match +directives in the configuration file that would apply are applied before the +configuration is written to standard output. +The connection parameters are supplied as keyword=value pairs and may be +supplied in any order, either with multiple +.Fl C +options or as a comma-separated list. +The keywords are +.Dq addr , +.Dq user , +.Dq host , +.Dq laddr , +.Dq lport , +and +.Dq rdomain +and correspond to source address, user, resolved source host name, +local address, local port number and routing domain respectively. +.It Fl c Ar host_certificate_file +Specifies a path to a certificate file to identify +.Nm +during key exchange. +The certificate file must match a host key file specified using the +.Fl h +option or the +.Cm HostKey +configuration directive. +.It Fl D +When this option is specified, +.Nm +will not detach and does not become a daemon. +This allows easy monitoring of +.Nm sshd . +.It Fl d +Debug mode. +The server sends verbose debug output to standard error, +and does not put itself in the background. +The server also will not +.Xr fork 2 +and will only process one connection. +This option is only intended for debugging for the server. +Multiple +.Fl d +options increase the debugging level. +Maximum is 3. +.It Fl E Ar log_file +Append debug logs to +.Ar log_file +instead of the system log. +.It Fl e +Write debug logs to standard error instead of the system log. +.It Fl f Ar config_file +Specifies the name of the configuration file. +The default is +.Pa /etc/ssh/sshd_config . +.Nm +refuses to start if there is no configuration file. +.It Fl g Ar login_grace_time +Gives the grace time for clients to authenticate themselves (default +120 seconds). +If the client fails to authenticate the user within +this many seconds, the server disconnects and exits. +A value of zero indicates no limit. +.It Fl h Ar host_key_file +Specifies a file from which a host key is read. +This option must be given if +.Nm +is not run as root (as the normal +host key files are normally not readable by anyone but root). +The default is +.Pa /etc/ssh/ssh_host_ecdsa_key , +.Pa /etc/ssh/ssh_host_ed25519_key +and +.Pa /etc/ssh/ssh_host_rsa_key . +It is possible to have multiple host key files for +the different host key algorithms. +.It Fl i +Specifies that +.Nm +is being run from +.Xr inetd 8 . +.It Fl o Ar option +Can be used to give options in the format used in the configuration file. +This is useful for specifying options for which there is no separate +command-line flag. +For full details of the options, and their values, see +.Xr sshd_config 5 . +.It Fl p Ar port +Specifies the port on which the server listens for connections +(default 22). +Multiple port options are permitted. +Ports specified in the configuration file with the +.Cm Port +option are ignored when a command-line port is specified. +Ports specified using the +.Cm ListenAddress +option override command-line ports. +.It Fl q +Quiet mode. +Nothing is sent to the system log. +Normally the beginning, +authentication, and termination of each connection is logged. +.It Fl T +Extended test mode. +Check the validity of the configuration file, output the effective configuration +to stdout and then exit. +Optionally, +.Cm Match +rules may be applied by specifying the connection parameters using one or more +.Fl C +options. +.It Fl t +Test mode. +Only check the validity of the configuration file and sanity of the keys. +This is useful for updating +.Nm +reliably as configuration options may change. +.It Fl u Ar len +This option is used to specify the size of the field +in the +.Li utmp +structure that holds the remote host name. +If the resolved host name is longer than +.Ar len , +the dotted decimal value will be used instead. +This allows hosts with very long host names that +overflow this field to still be uniquely identified. +Specifying +.Fl u0 +indicates that only dotted decimal addresses +should be put into the +.Pa utmp +file. +.Fl u0 +may also be used to prevent +.Nm +from making DNS requests unless the authentication +mechanism or configuration requires it. +Authentication mechanisms that may require DNS include +.Cm HostbasedAuthentication +and using a +.Cm from="pattern-list" +option in a key file. +Configuration options that require DNS include using a +USER@HOST pattern in +.Cm AllowUsers +or +.Cm DenyUsers . +.El +.Sh AUTHENTICATION +The OpenSSH SSH daemon supports SSH protocol 2 only. +Each host has a host-specific key, +used to identify the host. +Whenever a client connects, the daemon responds with its public +host key. +The client compares the +host key against its own database to verify that it has not changed. +Forward secrecy is provided through a Diffie-Hellman key agreement. +This key agreement results in a shared session key. +The rest of the session is encrypted using a symmetric cipher. +The client selects the encryption algorithm +to use from those offered by the server. +Additionally, session integrity is provided +through a cryptographic message authentication code (MAC). +.Pp +Finally, the server and the client enter an authentication dialog. +The client tries to authenticate itself using +host-based authentication, +public key authentication, +challenge-response authentication, +or password authentication. +.Pp +Regardless of the authentication type, the account is checked to +ensure that it is accessible. An account is not accessible if it is +locked, listed in +.Cm DenyUsers +or its group is listed in +.Cm DenyGroups +\&. The definition of a locked account is system dependent. Some platforms +have their own account database (eg AIX) and some modify the passwd field ( +.Ql \&*LK\&* +on Solaris and UnixWare, +.Ql \&* +on HP-UX, containing +.Ql Nologin +on Tru64, +a leading +.Ql \&*LOCKED\&* +on FreeBSD and a leading +.Ql \&! +on most Linuxes). +If there is a requirement to disable password authentication +for the account while allowing still public-key, then the passwd field +should be set to something other than these values (eg +.Ql NP +or +.Ql \&*NP\&* +). +.Pp +If the client successfully authenticates itself, a dialog for +preparing the session is entered. +At this time the client may request +things like allocating a pseudo-tty, forwarding X11 connections, +forwarding TCP connections, or forwarding the authentication agent +connection over the secure channel. +.Pp +After this, the client either requests an interactive shell or execution +or a non-interactive command, which +.Nm +will execute via the user's shell using its +.Fl c +option. +The sides then enter session mode. +In this mode, either side may send +data at any time, and such data is forwarded to/from the shell or +command on the server side, and the user terminal in the client side. +.Pp +When the user program terminates and all forwarded X11 and other +connections have been closed, the server sends command exit status to +the client, and both sides exit. +.Sh LOGIN PROCESS +When a user successfully logs in, +.Nm +does the following: +.Bl -enum -offset indent +.It +If the login is on a tty, and no command has been specified, +prints last login time and +.Pa /etc/motd +(unless prevented in the configuration file or by +.Pa ~/.hushlogin ; +see the +.Sx FILES +section). +.It +If the login is on a tty, records login time. +.It +Checks +.Pa /etc/nologin ; +if it exists, prints contents and quits +(unless root). +.It +Changes to run with normal user privileges. +.It +Sets up basic environment. +.It +Reads the file +.Pa ~/.ssh/environment , +if it exists, and users are allowed to change their environment. +See the +.Cm PermitUserEnvironment +option in +.Xr sshd_config 5 . +.It +Changes to user's home directory. +.It +If +.Pa ~/.ssh/rc +exists and the +.Xr sshd_config 5 +.Cm PermitUserRC +option is set, runs it; else if +.Pa /etc/ssh/sshrc +exists, runs +it; otherwise runs +.Xr xauth 1 . +The +.Dq rc +files are given the X11 +authentication protocol and cookie in standard input. +See +.Sx SSHRC , +below. +.It +Runs user's shell or command. +All commands are run under the user's login shell as specified in the +system password database. +.El +.Sh SSHRC +If the file +.Pa ~/.ssh/rc +exists, +.Xr sh 1 +runs it after reading the +environment files but before starting the user's shell or command. +It must not produce any output on stdout; stderr must be used +instead. +If X11 forwarding is in use, it will receive the "proto cookie" pair in +its standard input (and +.Ev DISPLAY +in its environment). +The script must call +.Xr xauth 1 +because +.Nm +will not run xauth automatically to add X11 cookies. +.Pp +The primary purpose of this file is to run any initialization routines +which may be needed before the user's home directory becomes +accessible; AFS is a particular example of such an environment. +.Pp +This file will probably contain some initialization code followed by +something similar to: +.Bd -literal -offset 3n +if read proto cookie && [ -n "$DISPLAY" ]; then + if [ `echo $DISPLAY | cut -c1-10` = 'localhost:' ]; then + # X11UseLocalhost=yes + echo add unix:`echo $DISPLAY | + cut -c11-` $proto $cookie + else + # X11UseLocalhost=no + echo add $DISPLAY $proto $cookie + fi | xauth -q - +fi +.Ed +.Pp +If this file does not exist, +.Pa /etc/ssh/sshrc +is run, and if that +does not exist either, xauth is used to add the cookie. +.Sh AUTHORIZED_KEYS FILE FORMAT +.Cm AuthorizedKeysFile +specifies the files containing public keys for +public key authentication; +if this option is not specified, the default is +.Pa ~/.ssh/authorized_keys +and +.Pa ~/.ssh/authorized_keys2 . +Each line of the file contains one +key (empty lines and lines starting with a +.Ql # +are ignored as +comments). +Public keys consist of the following space-separated fields: +options, keytype, base64-encoded key, comment. +The options field is optional. +The supported key types are: +.Pp +.Bl -item -compact -offset indent +.It +sk-ecdsa-sha2-nistp256@openssh.com +.It +ecdsa-sha2-nistp256 +.It +ecdsa-sha2-nistp384 +.It +ecdsa-sha2-nistp521 +.It +sk-ssh-ed25519@openssh.com +.It +ssh-ed25519 +.It +ssh-dss +.It +ssh-rsa +.El +.Pp +The comment field is not used for anything (but may be convenient for the +user to identify the key). +.Pp +Note that lines in this file can be several hundred bytes long +(because of the size of the public key encoding) up to a limit of +8 kilobytes, which permits RSA keys up to 16 kilobits. +You don't want to type them in; instead, copy the +.Pa id_dsa.pub , +.Pa id_ecdsa.pub , +.Pa id_ecdsa_sk.pub , +.Pa id_ed25519.pub , +.Pa id_ed25519_sk.pub , +or the +.Pa id_rsa.pub +file and edit it. +.Pp +.Nm +enforces a minimum RSA key modulus size of 1024 bits. +.Pp +The options (if present) consist of comma-separated option +specifications. +No spaces are permitted, except within double quotes. +The following option specifications are supported (note +that option keywords are case-insensitive): +.Bl -tag -width Ds +.It Cm agent-forwarding +Enable authentication agent forwarding previously disabled by the +.Cm restrict +option. +.It Cm cert-authority +Specifies that the listed key is a certification authority (CA) that is +trusted to validate signed certificates for user authentication. +.Pp +Certificates may encode access restrictions similar to these key options. +If both certificate restrictions and key options are present, the most +restrictive union of the two is applied. +.It Cm command="command" +Specifies that the command is executed whenever this key is used for +authentication. +The command supplied by the user (if any) is ignored. +The command is run on a pty if the client requests a pty; +otherwise it is run without a tty. +If an 8-bit clean channel is required, +one must not request a pty or should specify +.Cm no-pty . +A quote may be included in the command by quoting it with a backslash. +.Pp +This option might be useful +to restrict certain public keys to perform just a specific operation. +An example might be a key that permits remote backups but nothing else. +Note that the client may specify TCP and/or X11 +forwarding unless they are explicitly prohibited, e.g. using the +.Cm restrict +key option. +.Pp +The command originally supplied by the client is available in the +.Ev SSH_ORIGINAL_COMMAND +environment variable. +Note that this option applies to shell, command or subsystem execution. +Also note that this command may be superseded by a +.Xr sshd_config 5 +.Cm ForceCommand +directive. +.Pp +If a command is specified and a forced-command is embedded in a certificate +used for authentication, then the certificate will be accepted only if the +two commands are identical. +.It Cm environment="NAME=value" +Specifies that the string is to be added to the environment when +logging in using this key. +Environment variables set this way +override other default environment values. +Multiple options of this type are permitted. +Environment processing is disabled by default and is +controlled via the +.Cm PermitUserEnvironment +option. +.It Cm expiry-time="timespec" +Specifies a time after which the key will not be accepted. +The time may be specified as a YYYYMMDD date or a YYYYMMDDHHMM[SS] time +in the system time-zone. +.It Cm from="pattern-list" +Specifies that in addition to public key authentication, either the canonical +name of the remote host or its IP address must be present in the +comma-separated list of patterns. +See PATTERNS in +.Xr ssh_config 5 +for more information on patterns. +.Pp +In addition to the wildcard matching that may be applied to hostnames or +addresses, a +.Cm from +stanza may match IP addresses using CIDR address/masklen notation. +.Pp +The purpose of this option is to optionally increase security: public key +authentication by itself does not trust the network or name servers or +anything (but the key); however, if somebody somehow steals the key, the key +permits an intruder to log in from anywhere in the world. +This additional option makes using a stolen key more difficult (name +servers and/or routers would have to be compromised in addition to +just the key). +.It Cm no-agent-forwarding +Forbids authentication agent forwarding when this key is used for +authentication. +.It Cm no-port-forwarding +Forbids TCP forwarding when this key is used for authentication. +Any port forward requests by the client will return an error. +This might be used, e.g. in connection with the +.Cm command +option. +.It Cm no-pty +Prevents tty allocation (a request to allocate a pty will fail). +.It Cm no-user-rc +Disables execution of +.Pa ~/.ssh/rc . +.It Cm no-X11-forwarding +Forbids X11 forwarding when this key is used for authentication. +Any X11 forward requests by the client will return an error. +.It Cm permitlisten="[host:]port" +Limit remote port forwarding with the +.Xr ssh 1 +.Fl R +option such that it may only listen on the specified host (optional) and port. +IPv6 addresses can be specified by enclosing the address in square brackets. +Multiple +.Cm permitlisten +options may be applied separated by commas. +Hostnames may include wildcards as described in the PATTERNS section in +.Xr ssh_config 5 . +A port specification of +.Cm * +matches any port. +Note that the setting of +.Cm GatewayPorts +may further restrict listen addresses. +Note that +.Xr ssh 1 +will send a hostname of +.Dq localhost +if a listen host was not specified when the forwarding was requested, and +that this name is treated differently to the explicit localhost addresses +.Dq 127.0.0.1 +and +.Dq ::1 . +.It Cm permitopen="host:port" +Limit local port forwarding with the +.Xr ssh 1 +.Fl L +option such that it may only connect to the specified host and port. +IPv6 addresses can be specified by enclosing the address in square brackets. +Multiple +.Cm permitopen +options may be applied separated by commas. +No pattern matching or name lookup is performed on the +specified hostnames, they must be literal host names and/or addresses. +A port specification of +.Cm * +matches any port. +.It Cm port-forwarding +Enable port forwarding previously disabled by the +.Cm restrict +option. +.It Cm principals="principals" +On a +.Cm cert-authority +line, specifies allowed principals for certificate authentication as a +comma-separated list. +At least one name from the list must appear in the certificate's +list of principals for the certificate to be accepted. +This option is ignored for keys that are not marked as trusted certificate +signers using the +.Cm cert-authority +option. +.It Cm pty +Permits tty allocation previously disabled by the +.Cm restrict +option. +.It Cm no-touch-required +Do not require demonstration of user presence +for signatures made using this key. +This option only makes sense for the FIDO authenticator algorithms +.Cm ecdsa-sk +and +.Cm ed25519-sk . +.It Cm verify-required +Require that signatures made using this key attest that they verified +the user, e.g. via a PIN. +This option only makes sense for the FIDO authenticator algorithms +.Cm ecdsa-sk +and +.Cm ed25519-sk . +.It Cm restrict +Enable all restrictions, i.e. disable port, agent and X11 forwarding, +as well as disabling PTY allocation +and execution of +.Pa ~/.ssh/rc . +If any future restriction capabilities are added to authorized_keys files, +they will be included in this set. +.It Cm tunnel="n" +Force a +.Xr tun 4 +device on the server. +Without this option, the next available device will be used if +the client requests a tunnel. +.It Cm user-rc +Enables execution of +.Pa ~/.ssh/rc +previously disabled by the +.Cm restrict +option. +.It Cm X11-forwarding +Permits X11 forwarding previously disabled by the +.Cm restrict +option. +.El +.Pp +An example authorized_keys file: +.Bd -literal -offset 3n +# Comments are allowed at start of line.

each pattern in turn is matched against the host name. +When +.Nm sshd +is authenticating a client, such as when using +.Cm HostbasedAuthentication , +this will be the canonical client host name. +When +.Xr ssh 1 +is authenticating a server, this will be the host name +given by the user, the value of the +.Xr ssh 1 +.Cm HostkeyAlias +if it was specified, or the canonical server hostname if the +.Xr ssh 1 +.Cm CanonicalizeHostname +option was used. +.Pp +A pattern may also be preceded by +.Ql \&! +to indicate negation: if the host name matches a negated +pattern, it is not accepted (by that line) even if it matched another +pattern on the line. +A hostname or address may optionally be enclosed within +.Ql \&[ +and +.Ql \&] +brackets then followed by +.Ql \&: +and a non-standard port number. +.Pp +Alternately, hostnames may be stored in a hashed form which hides host names +and addresses should the file's contents be disclosed. +Hashed hostnames start with a +.Ql | +character. +Only one hashed hostname may appear on a single line and none of the above +negation or wildcard operators may be applied. +.Pp +The keytype and base64-encoded key are taken directly from the host key; they +can be obtained, for example, from +.Pa /etc/ssh/ssh_host_rsa_key.pub . +The optional comment field continues to the end of the line, and is not used. +.Pp +Lines starting with +.Ql # +and empty lines are ignored as comments. +.Pp +When performing host authentication, authentication is accepted if any +matching line has the proper key; either one that matches exactly or, +if the server has presented a certificate for authentication, the key +of the certification authority that signed the certificate. +For a key to be trusted as a certification authority, it must use the +.Dq @cert-authority +marker described above. +.Pp +The known hosts file also provides a facility to mark keys as revoked, +for example when it is known that the associated private key has been +stolen. +Revoked keys are specified by including the +.Dq @revoked +marker at the beginning of the key line, and are never accepted for +authentication or as certification authorities, but instead will +produce a warning from +.Xr ssh 1 +when they are encountered. +.Pp +It is permissible (but not +recommended) to have several lines or different host keys for the same +names. +This will inevitably happen when short forms of host names +from different domains are put in the file. +It is possible +that the files contain conflicting information; authentication is +accepted if valid information can be found from either file. +.Pp +Note that the lines in these files are typically hundreds of characters +long, and you definitely don't want to type in the host keys by hand. +Rather, generate them by a script, +.Xr ssh-keyscan 1 +or by taking, for example, +.Pa /etc/ssh/ssh_host_rsa_key.pub +and adding the host names at the front. +.Xr ssh-keygen 1 +also offers some basic automated editing for +.Pa ~/.ssh/known_hosts +including removing hosts matching a host name and converting all host +names to their hashed representations. +.Pp +An example ssh_known_hosts file: +.Bd -literal -offset 3n +# Comments allowed at start of line +closenet,...,192.0.2.53 1024 37 159...93 closenet.example.net +cvs.example.net,192.0.2.10 ssh-rsa AAAA1234.....= +# A hashed hostname +|1|JfKTdBh7rNbXkVAQCRp4OQoPfmI=|USECr3SWf1JUPsms5AqfD5QfxkM= ssh-rsa +AAAA1234.....= +# A revoked key +@revoked * ssh-rsa AAAAB5W... +# A CA key, accepted for any host in *.mydomain.com or *.mydomain.org +@cert-authority *.mydomain.org,*.mydomain.com ssh-rsa AAAAB5W... +.Ed +.Sh FILES +.Bl -tag -width Ds -compact +.It Pa ~/.hushlogin +This file is used to suppress printing the last login time and +.Pa /etc/motd , +if +.Cm PrintLastLog +and +.Cm PrintMotd , +respectively, +are enabled. +It does not suppress printing of the banner specified by +.Cm Banner . +.Pp +.It Pa ~/.rhosts +This file is used for host-based authentication (see +.Xr ssh 1 +for more information). +On some machines this file may need to be +world-readable if the user's home directory is on an NFS partition, +because +.Nm +reads it as root. +Additionally, this file must be owned by the user, +and must not have write permissions for anyone else. +The recommended +permission for most machines is read/write for the user, and not +accessible by others. +.Pp +.It Pa ~/.shosts +This file is used in exactly the same way as +.Pa .rhosts , +but allows host-based authentication without permitting login with +rlogin/rsh. +.Pp +.It Pa ~/.ssh/ +This directory is the default location for all user-specific configuration +and authentication information. +There is no general requirement to keep the entire contents of this directory +secret, but the recommended permissions are read/write/execute for the user, +and not accessible by others. +.Pp +.It Pa ~/.ssh/authorized_keys +Lists the public keys (DSA, ECDSA, Ed25519, RSA) +that can be used for logging in as this user. +The format of this file is described above. +The content of the file is not highly sensitive, but the recommended +permissions are read/write for the user, and not accessible by others. +.Pp +If this file, the +.Pa ~/.ssh +directory, or the user's home directory are writable +by other users, then the file could be modified or replaced by unauthorized +users. +In this case, +.Nm +will not allow it to be used unless the +.Cm StrictModes +option has been set to +.Dq no . +.Pp +.It Pa ~/.ssh/environment +This file is read into the environment at login (if it exists). +It can only contain empty lines, comment lines (that start with +.Ql # ) , +and assignment lines of the form name=value. +The file should be writable +only by the user;

sshd 8 +reads configuration data from +.Pa /etc/ssh/sshd_config +(or the file specified with +.Fl f +on the command line). +The file contains keyword-argument pairs, one per line. +For each keyword, the first obtained value will be used. +Lines starting with +.Ql # +and empty lines are interpreted as comments. +Arguments may optionally be enclosed in double quotes +.Pq \&" +in order to represent arguments containing spaces. +.Pp +The possible +keywords and their meanings are as follows (note that +keywords are case-insensitive and arguments are case-sensitive): +.Bl -tag -width Ds +.It Cm AcceptEnv +Specifies what environment variables sent by the client will be copied into +the session's +.Xr environ 7 . +See +.Cm SendEnv +and +.Cm SetEnv +in +.Xr ssh_config 5 +for how to configure the client. +The +.Ev TERM +environment variable is always accepted whenever the client +requests a pseudo-terminal as it is required by the protocol. +Variables are specified by name, which may contain the wildcard characters +.Ql * +and +.Ql \&? . +Multiple environment variables may be separated by whitespace or spread +across multiple +.Cm AcceptEnv +directives. +Be warned that some environment variables could be used to bypass restricted +user environments. +For this reason, care should be taken in the use of this directive. +The default is not to accept any environment variables. +.It Cm AddressFamily +Specifies which address family should be used by +.Xr sshd 8 . +Valid arguments are +.Cm any +(the default), +.Cm inet +(use IPv4 only), or +.Cm inet6 +(use IPv6 only). +.It Cm AllowAgentForwarding +Specifies whether +.Xr ssh-agent 1 +forwarding is permitted. +The default is +.Cm yes . +Note that disabling agent forwarding does not improve security +unless users are also denied shell access, as they can always install +their own forwarders. +.It Cm AllowGroups +This keyword can be followed by a list of group name patterns, separated +by spaces. +If specified, login is allowed only for users whose primary +group or supplementary group list matches one of the patterns. +Only group names are valid; a numerical group ID is not recognized. +By default, login is allowed for all groups. +The allow/deny groups directives are processed in the following order: +.Cm DenyGroups , +.Cm AllowGroups . +.Pp +See PATTERNS in +.Xr ssh_config 5 +for more information on patterns. +.It Cm AllowStreamLocalForwarding +Specifies whether StreamLocal (Unix-domain socket) forwarding is permitted. +The available options are +.Cm yes +(the default) +or +.Cm all +to allow StreamLocal forwarding, +.Cm no +to prevent all StreamLocal forwarding, +.Cm local +to allow local (from the perspective of +.Xr ssh 1 ) +forwarding only or +.Cm remote +to allow remote forwarding only. +Note that disabling StreamLocal forwarding does not improve security unless +users are also denied shell access, as they can always install their +own forwarders. +.It Cm AllowTcpForwarding +Specifies whether TCP forwarding is permitted. +The available options are +.Cm yes +(the default) +or +.Cm all +to allow TCP forwarding, +.Cm no +to prevent all TCP forwarding, +.Cm local +to allow local (from the perspective of +.Xr ssh 1 ) +forwarding only or +.Cm remote +to allow remote forwarding only. +Note that disabling TCP forwarding does not improve security unless +users are also denied shell access, as they can always install their +own forwarders. +.It Cm AllowUsers +This keyword can be followed by a list of user name patterns, separated +by spaces. +If specified, login is allowed only for user names that +match one of the patterns. +Only user names are valid; a numerical user ID is not recognized. +By default, login is allowed for all users. +If the pattern takes the form USER@HOST then USER and HOST +are separately checked, restricting logins to particular +users from particular hosts. +HOST criteria may additionally contain addresses to match in CIDR +address/masklen format. +The allow/deny users directives are processed in the following order: +.Cm DenyUsers , +.Cm AllowUsers . +.Pp +See PATTERNS in +.Xr ssh_config 5 +for more information on patterns. +.It Cm AuthenticationMethods +Specifies the authentication methods that must be successfully completed +for a user to be granted access. +This option must be followed by one or more lists of comma-separated +authentication method names, or by the single string +.Cm any +to indicate the default behaviour of accepting any single authentication +method. +If the default is overridden, then successful authentication requires +completion of every method in at least one of these lists. +.Pp +For example, +.Qq publickey,password publickey,keyboard-interactive +would require the user to complete public key authentication, followed by +either password or keyboard interactive authentication. +Only methods that are next in one or more lists are offered at each stage, +so for this example it would not be possible to attempt password or +keyboard-interactive authentication before public key. +.Pp +For keyboard interactive authentication it is also possible to +restrict authentication to a specific device by appending a +colon followed by the device identifier +.Cm bsdauth +or +.Cm pam . +depending on the server configuration. +For example, +.Qq keyboard-interactive:bsdauth +would restrict keyboard interactive authentication to the +.Cm bsdauth +device. +.Pp +If the publickey method is listed more than once, +.Xr sshd 8 +verifies that keys that have been used successfully are not reused for +subsequent authentications. +For example, +.Qq publickey,publickey +requires successful authentication using two different public keys. +.Pp +Note that each authentication method listed should also be explicitly enabled +in the configuration. +.Pp +The available authentication methods are: +.Qq gssapi-with-mic , +.Qq hostbased , +.Qq keyboard-interactive , +.Qq none +(used for access to password-less accounts when +.Cm PermitEmptyPasswords +is enabled), +.Qq password +and +.Qq publickey . +.It Cm AuthorizedKeysCommand +Specifies a program to be used to look up the user's public keys. +The program must be owned by root, not writable by group or others and +specified by an absolute path. +Arguments to +.Cm AuthorizedKeysCommand +accept the tokens described in the +.Sx TOKENS +section. +If no arguments are specified then the username of the target user is used. +.Pp +The program should produce on standard output zero or +more lines of authorized_keys output (see +.Sx AUTHORIZED_KEYS +in +.Xr sshd 8 ) . +.Cm AuthorizedKeysCommand +is tried after the usual +.Cm AuthorizedKeysFile +files and will not be executed if a matching key is found there. +By default, no +.Cm AuthorizedKeysCommand +is run. +.It Cm AuthorizedKeysCommandUser +Specifies the user under whose account the +.Cm AuthorizedKeysCommand +is run. +It is recommended to use a dedicated user that has no other role on the host +than running authorized keys commands. +If +.Cm AuthorizedKeysCommand +is specified but +.Cm AuthorizedKeysCommandUser +is not, then +.Xr sshd 8 +will refuse to start. +.It Cm AuthorizedKeysFile +Specifies the file that contains the public keys used for user authentication. +The format is described in the AUTHORIZED_KEYS FILE FORMAT section of +.Xr sshd 8 . +Arguments to +.Cm AuthorizedKeysFile +accept the tokens described in the +.Sx TOKENS +section. +After expansion, +.Cm AuthorizedKeysFile +is taken to be an absolute path or one relative to the user's home +directory. +Multiple files may be listed, separated by whitespace. +Alternately this option may be set to +.Cm none +to skip checking for user keys in files. +The default is +.Qq .ssh/authorized_keys .ssh/authorized_keys2 . +.It Cm AuthorizedPrincipalsCommand +Specifies a program to be used to generate the list of allowed +certificate principals as per +.Cm AuthorizedPrincipalsFile . +The program must be owned by root, not writable by group or others and +specified by an absolute path. +Arguments to +.Cm AuthorizedPrincipalsCommand +accept the tokens described in the +.Sx TOKENS +section. +If no arguments are specified then the username of the target user is used. +.Pp +The program should produce on standard output zero or +more lines of +.Cm AuthorizedPrincipalsFile +output. +If either +.Cm AuthorizedPrincipalsCommand +or +.Cm AuthorizedPrincipalsFile +is specified, then certificates offered by the client for authentication +must contain a principal that is listed. +By default, no +.Cm AuthorizedPrincipalsCommand +is run. +.It Cm AuthorizedPrincipalsCommandUser +Specifies the user under whose account the +.Cm AuthorizedPrincipalsCommand +is run. +It is recommended to use a dedicated user that has no other role on the host +than running authorized principals commands. +If +.Cm AuthorizedPrincipalsCommand +is specified but +.Cm AuthorizedPrincipalsCommandUser +is not, then +.Xr sshd 8 +will refuse to start. +.It Cm AuthorizedPrincipalsFile +Specifies a file that lists principal names that are accepted for +certificate authentication. +When using certificates signed by a key listed in +.Cm TrustedUserCAKeys , +this file lists names, one of which must appear in the certificate for it +to be accepted for authentication. +Names are listed one per line preceded by key options (as described in +.Sx AUTHORIZED_KEYS FILE FORMAT +in +.Xr sshd 8 ) . +Empty lines and comments starting with +.Ql # +are ignored. +.Pp +Arguments to +.Cm AuthorizedPrincipalsFile +accept the tokens described in the +.Sx TOKENS +section. +After expansion, +.Cm AuthorizedPrincipalsFile +is taken to be an absolute path or one relative to the user's home directory. +The default is +.Cm none , +i.e. not to use a principals file \(en in this case, the username +of the user must appear in a certificate's principals list for it to be +accepted. +.Pp +Note that +.Cm AuthorizedPrincipalsFile +is only used when authentication proceeds using a CA listed in +.Cm TrustedUserCAKeys +and is not consulted for certification authorities trusted via +.Pa ~/.ssh/authorized_keys , +though the +.Cm principals= +key option offers a similar facility (see +.Xr sshd 8 +for details). +.It Cm Banner +The contents of the specified file are sent to the remote user before +authentication is allowed. +If the argument is +.Cm none +then no banner is displayed. +By default, no banner is displayed. +.It Cm CASignatureAlgorithms +Specifies which algorithms are allowed for signing of certificates +by certificate authorities (CAs). +The default is: +.Bd -literal -offset indent +ssh-ed25519,ecdsa-sha2-nistp256, +ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, +sk-ssh-ed25519@openssh.com, +sk-ecdsa-sha2-nistp256@openssh.com, +rsa-sha2-512,rsa-sha2-256 +.Ed +.Pp +If the specified list begins with a +.Sq + +character, then the specified algorithms will be appended to the default set +instead of replacing them. +If the specified list begins with a +.Sq - +character, then the specified algorithms (including wildcards) will be removed +from the default set instead of replacing them. +.Pp +Certificates signed using other algorithms will not be accepted for +public key or host-based authentication. +.It Cm ChrootDirectory +Specifies the pathname of a directory to +.Xr chroot 2 +to after authentication. +At session startup +.Xr sshd 8 +checks that all components of the pathname are root-owned directories +which are not writable by any other user or group. +After the chroot, +.Xr sshd 8 +changes the working directory to the user's home directory. +Arguments to +.Cm ChrootDirectory +accept the tokens described in the +.Sx TOKENS +section. +.Pp +The +.Cm ChrootDirectory +must contain the necessary files and directories to support the +user's session. +For an interactive session this requires at least a shell, typically +.Xr sh 1 , +and basic +.Pa /dev +nodes such as +.Xr null 4 , +.Xr zero 4 , +.Xr stdin 4 , +.Xr stdout 4 , +.Xr stderr 4 , +and +.Xr tty 4 +devices. +For file transfer sessions using SFTP +no additional configuration of the environment is necessary if the in-process +sftp-server is used, +though sessions which use logging may require +.Pa /dev/log +inside the chroot directory on some operating systems (see +.Xr sftp-server 8 +for details). +.Pp +For safety, it is very important that the directory hierarchy be +prevented from modification by other processes on the system (especially +those outside the jail). +Misconfiguration can lead to unsafe environments which +.Xr sshd 8 +cannot detect. +.Pp +The default is +.Cm none , +indicating not to +.Xr chroot 2 . +.It Cm Ciphers +Specifies the ciphers allowed. +Multiple ciphers must be comma-separated. +If the specified list begins with a +.Sq + +character, then the specified ciphers will be appended to the default set +instead of replacing them. +If the specified list begins with a +.Sq - +character, then the specified ciphers (including wildcards) will be removed +from the default set instead of replacing them. +If the specified list begins with a +.Sq ^ +character, then the specified ciphers will be placed at the head of the +default set. +.Pp +The supported ciphers are: +.Pp +.Bl -item -compact -offset indent +.It +3des-cbc +.It +aes128-cbc +.It +aes192-cbc +.It +aes256-cbc +.It +aes128-ctr +.It +aes192-ctr +.It +aes256-ctr +.It +aes128-gcm@openssh.com +.It +aes256-gcm@openssh.com +.It +chacha20-poly1305@openssh.com +.El +.Pp +The default is: +.Bd -literal -offset indent +chacha20-poly1305@openssh.com, +aes128-ctr,aes192-ctr,aes256-ctr, +aes128-gcm@openssh.com,aes256-gcm@openssh.com +.Ed +.Pp +The list of available ciphers may also be obtained using +.Qq ssh -Q cipher . +.It Cm ClientAliveCountMax +Sets the number of client alive messages which may be sent without +.Xr sshd 8 +receiving any messages back from the client. +If this threshold is reached while client alive messages are being sent, +sshd will disconnect the client, terminating the session. +It is important to note that the use of client alive messages is very +different from +.Cm TCPKeepAlive . +The client alive messages are sent through the encrypted channel +and therefore will not be spoofable. +The TCP keepalive option enabled by +.Cm TCPKeepAlive +is spoofable. +The client alive mechanism is valuable when the client or +server depend on knowing when a connection has become unresponsive. +.Pp +The default value is 3. +If +.Cm ClientAliveInterval +is set to 15, and +.Cm ClientAliveCountMax +is left at the default, unresponsive SSH clients +will be disconnected after approximately 45 seconds. +Setting a zero +.Cm ClientAliveCountMax +disables connection termination. +.It Cm ClientAliveInterval +Sets a timeout interval in seconds after which if no data has been received +from the client, +.Xr sshd 8 +will send a message through the encrypted +channel to request a response from the client. +The default +is 0, indicating that these messages will not be sent to the client. +.It Cm Compression +Specifies whether compression is enabled after +the user has authenticated successfully. +The argument must be +.Cm yes , +.Cm delayed +(a legacy synonym for +.Cm yes ) +or +.Cm no . +The default is +.Cm yes . +.It Cm DenyGroups +This keyword can be followed by a list of group name patterns, separated +by spaces. +Login is disallowed for users whose primary group or supplementary +group list matches one of the patterns. +Only group names are valid; a numerical group ID is not recognized. +By default, login is allowed for all groups. +The allow/deny groups directives are processed in the following order: +.Cm DenyGroups , +.Cm AllowGroups . +.Pp +See PATTERNS in +.Xr ssh_config 5 +for more information on patterns. +.It Cm DenyUsers +This keyword can be followed by a list of user name patterns, separated +by spaces. +Login is disallowed for user names that match one of the patterns. +Only user names are valid; a numerical user ID is not recognized. +By default, login is allowed for all users. +If the pattern takes the form USER@HOST then USER and HOST +are separately checked, restricting logins to particular +users from particular hosts. +HOST criteria may additionally contain addresses to match in CIDR +address/masklen format. +The allow/deny users directives are processed in the following order: +.Cm DenyUsers , +.Cm AllowUsers . +.Pp +See PATTERNS in +.Xr ssh_config 5 +for more information on patterns. +.It Cm DisableForwarding +Disables all forwarding features, including X11, +.Xr ssh-agent 1 , +TCP and StreamLocal. +This option overrides all other forwarding-related options and may +simplify restricted configurations. +.It Cm ExposeAuthInfo +Writes a temporary file containing a list of authentication methods and +public credentials (e.g. keys) used to authenticate the user. +The location of the file is exposed to the user session through the +.Ev SSH_USER_AUTH +environment variable. +The default is +.Cm no . +.It Cm FingerprintHash +Specifies the hash algorithm used when logging key fingerprints. +Valid options are: +.Cm md5 +and +.Cm sha256 . +The default is +.Cm sha256 . +.It Cm ForceCommand +Forces the execution of the command specified by +.Cm ForceCommand , +ignoring any command supplied by the client and +.Pa ~/.ssh/rc +if present. +The command is invoked by using the user's login shell with the -c option. +This applies to shell, command, or subsystem execution. +It is most useful inside a +.Cm Match +block. +The command originally supplied by the client is available in the +.Ev SSH_ORIGINAL_COMMAND +environment variable. +Specifying a command of +.Cm internal-sftp +will force the use of an in-process SFTP server that requires no support +files when used with +.Cm ChrootDirectory . +The default is +.Cm none . +.It Cm GatewayPorts +Specifies whether remote hosts are allowed to connect to ports +forwarded for the client. +By default, +.Xr sshd 8 +binds remote port forwardings to the loopback address. +This prevents other remote hosts from connecting to forwarded ports. +.Cm GatewayPorts +can be used to specify that sshd +should allow remote port forwardings to bind to non-loopback addresses, thus +allowing other hosts to connect. +The argument may be +.Cm no +to force remote port forwardings to be available to the local host only, +.Cm yes

+If the socket file already exists and +.Cm StreamLocalBindUnlink +is not enabled, +.Nm sshd +will be unable to forward the port to the Unix-domain socket file. +This option is only used for port forwarding to a Unix-domain socket file. +.Pp +The argument must be +.Cm yes +or +.Cm no . +The default is +.Cm no . +.It Cm StrictModes +Specifies whether +.Xr sshd 8 +should check file modes and ownership of the +user's files and home directory before accepting login. +This is normally desirable because novices sometimes accidentally leave their +directory or files world-writable. +The default is +.Cm yes . +Note that this does not apply to +.Cm ChrootDirectory , +whose permissions and ownership are checked unconditionally. +.It Cm Subsystem +Configures an external subsystem (e.g. file transfer daemon). +Arguments should be a subsystem name and a command (with optional arguments) +to execute upon subsystem request. +.Pp +The command +.Cm sftp-server +implements the SFTP file transfer subsystem. +.Pp +Alternately the name +.Cm internal-sftp +implements an in-process SFTP server. +This may simplify configurations using +.Cm ChrootDirectory +to force a different filesystem root on clients. +.Pp +By default no subsystems are defined. +.It Cm SyslogFacility +Gives the facility code that is used when logging messages from +.Xr sshd 8 . +The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, +LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. +The default is AUTH. +.It Cm TCPKeepAlive +Specifies whether the system should send TCP keepalive messages to the +other side. +If they are sent, death of the connection or crash of one +of the machines will be properly noticed. +However, this means that +connections will die if the route is down temporarily, and some people +find it annoying. +On the other hand, if TCP keepalives are not sent, +sessions may hang indefinitely on the server, leaving +.Qq ghost +users and consuming server resources. +.Pp +The default is +.Cm yes +(to send TCP keepalive messages), and the server will notice +if the network goes down or the client host crashes. +This avoids infinitely hanging sessions. +.Pp +To disable TCP keepalive messages, the value should be set to +.Cm no . +.It Cm TrustedUserCAKeys +Specifies a file containing public keys of certificate authorities that are +trusted to sign user certificates for authentication, or +.Cm none +to not use one. +Keys are listed one per line; empty lines and comments starting with +.Ql # +are allowed. +If a certificate is presented for authentication and has its signing CA key +listed in this file, then it may be used for authentication for any user +listed in the certificate's principals list. +Note that certificates that lack a list of principals will not be permitted +for authentication using +.Cm TrustedUserCAKeys . +For more details on certificates, see the CERTIFICATES section in +.Xr ssh-keygen 1 . +.It Cm UseDNS +Specifies whether +.Xr sshd 8 +should look up the remote host name, and to check that +the resolved host name for the remote IP address maps back to the +very same IP address. +.Pp +If this option is set to +.Cm no +(the default) then only addresses and not host names may be used in +.Pa ~/.ssh/authorized_keys +.Cm from +and +.Nm +.Cm Match +.Cm Host +directives. +.It Cm UsePAM +Enables the Pluggable Authentication Module interface. +If set to +.Cm yes +this will enable PAM authentication using +.Cm KbdInteractiveAuthentication +and +.Cm PasswordAuthentication +in addition to PAM account and session module processing for all +authentication types. +.Pp +Because PAM keyboard-interactive authentication usually serves an equivalent +role to password authentication, you should disable either +.Cm PasswordAuthentication +or +.Cm KbdInteractiveAuthentication . +.Pp +If +.Cm UsePAM +is enabled, you will not be able to run +.Xr sshd 8 +as a non-root user. +The default is +.Cm no . +.It Cm VersionAddendum +Optionally specifies additional text to append to the SSH protocol banner +sent by the server upon connection. +The default is +.Cm none . +.It Cm X11DisplayOffset +Specifies the first display number available for +.Xr sshd 8 Ns 's +X11 forwarding. +This prevents sshd from interfering with real X11 servers. +The default is 10. +.It Cm X11Forwarding +Specifies whether X11 forwarding is permitted. +The argument must be +.Cm yes +or +.Cm no . +The default is +.Cm no . +.Pp +When X11 forwarding is enabled, there may be additional exposure to +the server and to client displays if the +.Xr sshd 8 +proxy display is configured to listen on the wildcard address (see +.Cm X11UseLocalhost ) , +though this is not the default. +Additionally, the authentication spoofing and authentication data +verification and substitution occur on the client side. +The security risk of using X11 forwarding is that the client's X11 +display server may be exposed to attack when the SSH client requests +forwarding (see the warnings for +.Cm ForwardX11 +in +.Xr ssh_config 5 ) . +A system administrator may have a stance in which they want to +protect clients that may expose themselves to attack by unwittingly +requesting X11 forwarding, which can warrant a +.Cm no +setting. +.Pp +Note that disabling X11 forwarding does not prevent users from +forwarding X11 traffic, as users can always install their own forwarders. +.It Cm X11UseLocalhost +Specifies whether +.Xr sshd 8 +should bind the X11 forwarding server to the loopback address or to +the wildcard address. +By default, +sshd binds the forwarding server to the loopback address and sets the +hostname part of the +.Ev DISPLAY +environment variable to +.Cm localhost . +This prevents remote hosts from connecting to the proxy display. +However, some older X11 clients may not function with this +configuration. +.Cm X11UseLocalhost +may be set to +.Cm no +to specify that the forwarding server should be bound to the wildcard +address. +The argument must be +.Cm yes +or +.Cm no . +The default is +.Cm yes . +.It Cm XAuthLocation +Specifies the full pathname of the +.Xr xauth 1 +program, or +.Cm none +to not use one. +The default is +.Pa /usr/X11R6/bin/xauth . +.El +.Sh TIME FORMATS +.Xr sshd 8 +command-line arguments and configuration file options that specify time +may be expressed using a sequence of the form: +.Sm off +.Ar time Op Ar qualifier , +.Sm on +where +.Ar time +is a positive integer value and +.Ar qualifier +is one of the following: +.Pp +.Bl -tag -width Ds -compact -offset indent +.It Aq Cm none +seconds +.It Cm s | Cm S +seconds +.It Cm m | Cm M +minutes +.It Cm h | Cm H +hours +.It Cm d | Cm D +days +.It Cm w | Cm W +weeks +.El +.Pp +Each member of the sequence is added together to

User interfaces and operating systems use system-dependent pathname + * strings to name files and directories. This class presents an + * abstract, system-independent view of hierarchical pathnames. An + * abstract pathname has two components: + * + *

    + *
  1. An optional system-dependent prefix string, + * such as a disk-drive specifier, "/" for the UNIX root + * directory, or "\\\\" for a Microsoft Windows UNC pathname, and + *
  2. A sequence of zero or more string names. + *
+ * + * The first name in an abstract pathname may be a directory name or, in the + * case of Microsoft Windows UNC pathnames, a hostname. Each subsequent name + * in an abstract pathname denotes a directory; the last name may denote + * either a directory or a file. The empty abstract pathname has no + * prefix and an empty name sequence. + * + *

The conversion of a pathname string to or from an abstract pathname is + * inherently system-dependent. When an abstract pathname is converted into a + * pathname string, each name is separated from the next by a single copy of + * the default separator character. The default name-separator + * character is defined by the system property file.separator, and + * is made available in the public static fields {@link + * #separator} and {@link #separatorChar} of this class. + * When a pathname string is converted into an abstract pathname, the names + * within it may be separated by the default name-separator character or by any + * other name-separator character that is supported by the underlying system. + * + *

A pathname, whether abstract or in string form, may be either + * absolute or relative. An absolute pathname is complete in + * that no other information is required in order to locate the file that it + * denotes. A relative pathname, in contrast, must be interpreted in terms of + * information taken from some other pathname. By default the classes in the + * java.io package always resolve relative pathnames against the + * current user directory. This directory is named by the system property + * user.dir, and is typically the directory in which the Java + * virtual machine was invoked. + * + *

The parent of an abstract pathname may be obtained by invoking + * the {@link #getParent} method of this class and consists of the pathname's + * prefix and each name in the pathname's name sequence except for the last. + * Each directory's absolute pathname is an ancestor of any File + * object with an absolute abstract pathname which begins with the directory's + * absolute pathname. For example, the directory denoted by the abstract + * pathname "/usr" is an ancestor of the directory denoted by the + * pathname "/usr/local/bin". + * + *

The prefix concept is used to handle root directories on UNIX platforms, + * and drive specifiers, root directories and UNC pathnames on Microsoft Windows platforms, + * as follows: + * + *

    + * + *
  • For UNIX platforms, the prefix of an absolute pathname is always + * "/". Relative pathnames have no prefix. The abstract pathname + * denoting the root directory has the prefix "/" and an empty + * name sequence. + * + *
  • For Microsoft Windows platforms, the prefix of a pathname that contains a drive + * specifier consists of the drive letter followed by ":" and + * possibly followed by "\\" if the pathname is absolute. The + * prefix of a UNC pathname is "\\\\"; the hostname and the share + * name are the first two names in the name sequence. A relative pathname that + * does not specify a drive has no prefix. + * + *
+ * + *

Instances of this class may or may not denote an actual file-system + * object such as a file or a directory. If it does denote such an object + * then that object resides in a partition. A partition is an + * operating system-specific portion of storage for a file system. A single + * storage device (e.g. a physical disk-drive, flash memory, CD-ROM) may + * contain multiple partitions. The object, if any, will reside on the + * partition named by some ancestor of the absolute + * form of this pathname. + * + *

A file system may implement restrictions to certain operations on the + * actual file-system object, such as reading, writing, and executing. These + * restrictions are collectively known as access permissions. The file + * system may have multiple sets of access permissions on a single object. + * For example, one set may apply to the object's owner, and another + * may apply to all other users. The access permissions on an object may + * cause some methods in this class to fail. + * + *

Instances of the File class are immutable; that is, once + * created, the abstract pathname represented by a File object + * will never change. + * + *

Interoperability with {@code java.nio.file} package

+ * + *

The {@code java.nio.file} + * package defines interfaces and classes for the Java virtual machine to access + * files, file attributes, and file systems. This API may be used to overcome + * many of the limitations of the {@code java.io.File} class. + * The {@link #toPath toPath} method may be used to obtain a {@link + * Path} that uses the abstract path represented by a {@code File} object to + * locate a file. The resulting {@code Path} may be used with the {@link + * java.nio.file.Files} class to provide more efficient and extensive access to + * additional file operations, file attributes, and I/O exceptions to help + * diagnose errors when an operation on a file fails. + * + *

On Android strings are converted to UTF-8 byte sequences when sending filenames to + * the operating system, and byte sequences returned by the operating system (from the + * various {@code list} methods) are converted to strings by decoding them as UTF-8 + * byte sequences. + * + * @author unascribed + * @since JDK1.0 + */ + +public class File + implements Serializable, Comparable +{ + + /** + * The FileSystem object representing the platform's local file system. + */ + private static final FileSystem fs = DefaultFileSystem.getFileSystem(); + + /** + * This abstract pathname's normalized pathname string.

Textual representation of IP addresses

+ * + * Textual representation of IPv6 address used as input to methods + * takes one of the following forms: + * + *
    + *

  1. The preferred form is x:x:x:x:x:x:x:x, + * where the 'x's are + * the hexadecimal values of the eight 16-bit pieces of the + * address. This is the full form. For example, + * + *

    + * + *
    {@code 1080:0:0:0:8:800:200C:417A}
    + * + *

    Note that it is not necessary to write the leading zeros in + * an individual field. However, there must be at least one numeral + * in every field, except as described below.

    2. + * + *

  2. Due to some methods of allocating certain styles of IPv6 + * addresses, it will be common for addresses to contain long + * strings of zero bits. In order to make writing addresses + * containing zero bits easier, a special syntax is available to + * compress the zeros. The use of "::" indicates multiple groups + * of 16-bits of zeros. The "::" can only appear once in an address. + * The "::" can also be used to compress the leading and/or trailing + * zeros in an address. For example, + * + *

    + * + *
    {@code 1080::8:800:200C:417A}
    + * + *

  3. An alternative form that is sometimes more convenient + * when dealing with a mixed environment of IPv4 and IPv6 nodes is + * x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values + * of the six high-order 16-bit pieces of the address, and the 'd's + * are the decimal values of the four low-order 8-bit pieces of the + * standard IPv4 representation address, for example, + * + *

    + * + * + *
    {@code ::FFFF:129.144.52.38}
    {@code ::129.144.52.38}
    + * + *

    where "::FFFF:d.d.d.d" and "::d.d.d.d" are, respectively, the + * general forms of an IPv4-mapped IPv6 address and an + * IPv4-compatible IPv6 address. Note that the IPv4 portion must be + * in the "d.d.d.d" form. The following forms are invalid: + * + *

    + * + * + * + * + *
    {@code ::FFFF:d.d.d}
    {@code ::FFFF:d.d}
    {@code ::d.d.d}
    {@code ::d.d}
    + * + *

    The following form: + * + *

    + * + *
    {@code ::FFFF:d}
    + * + *

    is valid, however it is an unconventional representation of + * the IPv4-compatible IPv6 address, + * + *

    + * + *

Special IPv6 address

+ * + *
+ * + * + * + *
IPv4-mapped addressOf the form::ffff:w.x.y.z, this IPv6 address is used to + * represent an IPv4 address. It allows the native program to + * use the same address data structure and also the same + * socket when communicating with both IPv4 and IPv6 nodes. + * + *

In InetAddress and Inet6Address, it is used for internal + * representation; it has no functional role. Java will never + * return an IPv4-mapped address. These classes can take an + * IPv4-mapped address as input, both in byte array and text + * representation. However, it will be converted into an IPv4 + * address.

+ * + *

Textual representation of IPv6 scoped addresses

+ * + *

The textual representation of IPv6 addresses as described above can be + * extended to specify IPv6 scoped addresses. This extension to the basic + * addressing architecture is described in [draft-ietf-ipngwg-scoping-arch-04.txt]. + * + *

Because link-local and site-local addresses are non-global, it is possible + * that different hosts may have the same destination address and may be + * reachable through different interfaces on the same originating system. In + * this case, the originating system is said to be connected to multiple zones + * of the same scope. In order to disambiguate which is the intended destination + * zone, it is possible to append a zone identifier (or scope_id) to an + * IPv6 address. + * + *

The general format for specifying the scope_id is the following: + * + *

IPv6-address%scope_id
+ *

The IPv6-address is a literal IPv6 address as described above. + * The scope_id refers to an interface on the local system, and it can be + * specified in two ways. + *

  1. As a numeric identifier. This must be a positive integer + * that identifies the particular interface and scope as understood by the + * system. Usually, the numeric values can be determined through administration + * tools on the system. Each interface may have multiple values, one for each + * scope. If the scope is unspecified, then the default value used is zero.
    2. + *
  2. As a string. This must be the exact string that is returned by + * {@link java.net.NetworkInterface#getName()} for the particular interface in + * question. When an Inet6Address is created in this way, the numeric scope-id + * is determined at the time the object is created by querying the relevant + * NetworkInterface.
+ * + *

Note also, that the numeric scope_id can be retrieved from + * Inet6Address instances returned from the NetworkInterface class. This can be + * used to find out the current scope ids configured on the system. + * @since 1.4 + */ + +public final +class Inet6Address extends InetAddress { + final static int INADDRSZ = 16; + + // BEGIN Android-removed: Remove special handling for link-local addresses. + /* + * cached scope_id - for link-local address use only. + * + private transient int cached_scope_id; // 0 + */ + // END Android-removed: Remove special handling for link-local addresses. + + // BEGIN Android-added: Define special-purpose IPv6 address. + /** + * Reserved address for {@code INADDR_ANY}, to specify any IPv6 address at all. + * + * @hide + */ + public static final InetAddress ANY = + new Inet6Address("::", new byte[] {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }, 0); + + /** + * Loopback address to the local host. + * + * @hide + */ + public static final InetAddress LOOPBACK = new Inet6Address("ip6-localhost", + new byte[] {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1}, 0); + // END Android-added: Define special-purpose IPv6 address. + + private class Inet6AddressHolder { + + private Inet6AddressHolder() { + ipaddress = new byte[INADDRSZ]; + } + + private Inet6AddressHolder( + byte[] ipaddress, int scope_id, boolean scope_id_set, + NetworkInterface ifname, boolean scope_ifname_set) + { + this.ipaddress = ipaddress; + this.scope_id = scope_id; + this.scope_id_set = scope_id_set; + this.scope_ifname_set = scope_ifname_set; + this.scope_ifname = ifname; + } + + /** + * Holds a 128-bit (16 bytes) IPv6 address. + */ + byte[] ipaddress; + + /** + * scope_id.
