1openssh (1:5.4p1-2) unstable; urgency=low
2
3 Smartcard support is now available using PKCS#11 tokens. If you were
4 previously using an unofficial build of Debian's OpenSSH package with
5 OpenSC-based smartcard support added, then note that commands like
6 'ssh-add -s 0' will no longer work; you need to use 'ssh-add -s
7 /usr/lib/opensc-pkcs11.so' instead.

11openssh (1:3.8.1p1-9) experimental; urgency=low
12
13 The ssh package has been split into openssh-client and openssh-server. If
14 you had previously requested that the sshd server should not be run, then
15 that request will still be honoured. However, the recommended approach is
16 now to remove the openssh-server package if you do not want to run sshd.
17 You can remove the old /etc/ssh/sshd_not_to_be_run marker file after doing
18 that.

22openssh (1:3.5p1-1) unstable; urgency=low
23
24 This version of OpenSSH disables the environment option for public keys by
25 default, in order to avoid certain attacks (for example, LD_PRELOAD). If
26 you are using this option in an authorized_keys file, beware that the keys
27 in question will no longer work until the option is removed.
28
29 To re-enable this option, set "PermitUserEnvironment yes" in
30 /etc/ssh/sshd_config after the upgrade is complete, taking note of the
31 warning in the sshd_config(5) manual page.

35openssh (1:3.0.1p1-1) unstable; urgency=high
36
37 As of version 3, OpenSSH no longer uses separate files for ssh1 and ssh2
38 keys. This means the authorized_keys2 and known_hosts2 files are no longer
39 needed. They will still be read in order to maintain backward
40 compatibility.

1OpenSSH for Debian
2------------------
3
4UPGRADE ISSUES
5==============
6
7Privilege Separation
8--------------------
9
10As of 3.3, openssh has employed privilege separation to reduce the
11quantity of code that runs as root, thereby reducing the impact of
12some security holes in sshd. This now also works properly with PAM.
13
14Privilege separation is turned on by default, so, if you decide you
15want it turned off, you need to add "UsePrivilegeSeparation no" to
16/etc/ssh/sshd_config.
17
18PermitRootLogin set to yes
19--------------------------
20
21This is now the default setting (in line with upstream), and people
22who asked for an automatically-generated configuration file when
23upgrading from potato (or on a new install) will have this setting in
24their /etc/ssh/sshd_config file.
25
26Should you wish to change this setting, edit /etc/ssh/sshd_config, and
27change:
28PermitRootLogin yes
29to:
30PermitRootLogin no
31
32Having PermitRootLogin set to yes means that an attacker that knows
33the root password can ssh in directly (without having to go via a user
34account). If you set it to no, then they must compromise a normal user
35account. In the vast majority of cases, this does not give added
36security; remember that any account you su to root from is equivalent
37to root - compromising this account gives an attacker access to root
38easily. If you only ever log in as root from the physical console,
39then you probably want to set this value to no.
40
41As an aside, PermitRootLogin can also be set to "without-password" or
42"forced-commands-only" - see sshd(8) for more details.
43
44DO NOT FILE BUG REPORTS SAYING YOU THINK THIS DEFAULT IS INCORRECT!
45
46The argument above is somewhat condensed; I have had this discussion
47at great length with many people. If you think the default is
48incorrect, and feel strongly enough to want to argue about it, then
49send email to debian-ssh@lists.debian.org. I will close bug reports
50claiming the default is incorrect.
51
52SSH now uses protocol 2 by default
53----------------------------------
54
55This means all your keyfiles you used for protocol version 1 need to
56be re-generated. The server keys are done automatically, but for RSA
57authentication, please read the ssh-keygen manpage.
58
59If you have an automatically generated configuration file, and decide
60at a later stage that you do want to support protocol version 1 (not
61recommended, but note that the ssh client shipped with Debian potato
62only supported protocol version 1), then you need to do the following:
63
64Change /etc/ssh/sshd_config such that:
65Protocol 2
66becomes:
67Protocol 2,1
68Also add the line:
69HostKey /etc/ssh/ssh_host_key
70
71If you do not already have an RSA1 host key in /etc/ssh/ssh_host_key,
72you will need to generate one. To do so, run this command as root:
73
74 ssh-keygen -f /etc/ssh/ssh_host_key -N '' -t rsa1
75
76As of openssh-server 1:4.1p1-2, the option to support protocol version 1
77is no longer available via debconf. You must edit the configuration file
78instead.
79
80X11 Forwarding
81--------------
82
83ssh's default for ForwardX11 has been changed to ``no'' because it has
84been pointed out that logging into remote systems administered by
85untrusted people is likely to open you up to X11 attacks, so you
86should have to actively decide that you trust the remote machine's
87root, before enabling X11. I strongly recommend that you do this on a
88machine-by-machine basis, rather than just enabling it in the default
89host settings.
90
91In order for X11 forwarding to work, you need to install xauth on the
92server. In Debian this is in the xbase-clients package.
93
94As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
95the security risks of X11 forwarding. Look up X11UseLocalhost in
96sshd_config(8) if this is a problem.
97
98OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
99ssh client to create an untrusted X cookie so that attacks on the
100forwarded X11 connection can't become attacks on X clients on the remote
101machine. However, this has some problems in implementation - notably a
102very short timeout of the untrusted cookie - breaks large numbers of
103existing setups, and generally seems immature. The Debian package
104therefore sets the default for this option to "yes" (in ssh itself,
105rather than in ssh_config).
106
107Fallback to RSH
108---------------
109
110The default for this setting has been changed from Yes to No, for
111security reasons, and to stop the delay attempting to rsh to machines
112that don't offer the service. Simply switch it back on in either
113/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
114it for.
115
116Setgid ssh-agent and environment variables
117------------------------------------------
118
119As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
120attacks retrieving private key material. This has the side-effect of causing
121glibc to remove certain environment variables which might have security
122implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
123TMPDIR.
124
125If you need to set any of these environment variables, you will need to do
126so in the program exec()ed by ssh-agent. This may involve creating a small
127wrapper script.
128
129Symlink Hostname invocation
130---------------------------
131
132This version of ssh no longer includes support for invoking ssh with the
133hostname as the name of the file run. People wanting this support should
134use the ssh-argv0 script.
135
136=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
137
138OTHER ISSUES
139============
140
141/usr/bin/ssh not SUID
142---------------------
143
144Due to Debian bug #164325, RhostsRSAAuthentication can only be used if ssh
145is SUID. Until this is fixed, if that is a problem, use:
146
147 dpkg-statoverride
148
149or if that's also missing, use this:
150
151 chown root.root /usr/bin/ssh
152 chmod 04755 /usr/bin/ssh
153
154Authorization Forwarding
155------------------------
156
157Similarly, root on a remote server could make use of your ssh-agent
158(while you're logged into their machine) to obtain access to machines
159which trust your keys. This feature is therefore disabled by default.
160You should only re-enable it for those hosts (in your ~/.ssh/config or
161/etc/ssh/ssh_config) where you are confident that the remote machine
162is not a threat.
163
164Problems logging in with RSA authentication
165-------------------------------------------
166
167If you have trouble logging in with RSA authentication then the
168problem is probably caused by the fact that you have your home
169directory writable by group, as well as user (this is the default on
170Debian systems).
171
172Depending upon other settings on your system (i.e. other users being
173in your group) this could open a security hole, so you will need to
174make your home directory writable only by yourself. Run this command,
175as yourself:
176
177 chmod g-w ~/
178
179to remove group write permissions. If you use ssh-copy-id to install your
180keys, it does this for you.
181
182-L option of ssh nonfree
183------------------------
184
185non-free ssh supported the usage of the option -L to use a non privileged
186port for scp. This option will not be supported by scp from openssh.
187
188Please use instead scp -o "UsePrivilegedPort=no" as documented in the
189manpage to scp itself.
190
191Problem logging in because of TCP-Wrappers
192------------------------------------------
193
194ssh is compiled with support for tcp-wrappers. So if you can no longer
195log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
196are configured so that ssh is not blocked.
197
198Kerberos support
199----------------
200
201ssh is now compiled with Kerberos support. Unfortunately, privilege
202separation is incompatible with Kerberos support for SSH protocol 1 and
203parts of the support for protocol 2; you may need to run kinit after logging
204in.
205
206Interoperability between scp and the ssh.com SSH server
207-------------------------------------------------------
208
209In version 2 and greater of the commercial SSH server produced by SSH
210Communications Security, scp was changed to use SFTP (SSH2's file transfer
211protocol) instead of the traditional rcp-over-ssh, thereby breaking
212compatibility. The OpenSSH developers regard this as a bug in the ssh.com
213server, and do not currently intend to change OpenSSH's scp to match.
214
215Workarounds for this problem are to install scp1 on the server (scp2 will
216fall back to it), to use sftp, or to use some other transfer mechanism such
217as rsync-over-ssh or tar-over-ssh.
218
219Running sshd from inittab
220-------------------------
221
222Some people find it useful to run the sshd server from inittab, to make sure
223that it always stays running. To do this, stop sshd ('/etc/init.d/ssh
224stop'), add the following line to /etc/inittab, and run 'telinit q':
225
226 ss:2345:respawn:/usr/sbin/sshd -D
227
228If you do this, note that you will need to stop sshd being started in the
229normal way ('rm -f /etc/rc[2345].d/S16ssh') and that you will need to
230restart this sshd manually on upgrades.

29 commandline using the "-a" (append) option (closes: #158590).
30 + ssh(1): add an "IgnoreUnknown" configuration option to selectively
31 suppress errors arising from unknown configuration directives
32 (closes: #436052).
33 + sftp(1): update progressmeter when data is acknowledged, not when
34 it's sent (partially addresses #708372).
35 + ssh(1): do not fatally exit when attempting to cleanup multiplexing-
36 created channels that are incompletely opened (closes: #651357).
37 - 6.4/6.4p1 (http://www.openssh.com/txt/release-6.4):
38 + CVE-2013-4548: sshd(8): fix a memory corruption problem triggered
39 during rekeying when an AES-GCM cipher is selected (closes:
40 #729029). Full details of the vulnerability are available at:
41 http://www.openssh.com/txt/gcmrekey.adv
42 * When running under Upstart, only consider the daemon started once it is
43 ready to accept connections (by raising SIGSTOP at that point and using

82 * If the running init daemon is Upstart, then, on the first upgrade to
83 this version, check whether sysvinit is still managing sshd; if so,
84 manually stop it so that it can be restarted under upstart. We do this
85 near the end of the postinst, so it shouldn't result in any appreciable
86 extra window where sshd is not running during upgrade.

91
92 * Change start condition of Upstart job to be just the standard "runlevel
93 [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
94 it unreasonably difficult to ensure that urandom starts before ssh, and
95 is not really necessary since one of static-network-up and failsafe-boot
96 is guaranteed to happen and will trigger entry to the default runlevel,
97 and we don't care about ssh starting before the network (LP: #1098299).
98 * Drop conffile handling for direct upgrades from pre-split ssh package;
99 this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
100 truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
101 now four Debian releases ago, we can afford to drop this and simplify
102 the packaging.
103 * Remove ssh/use_old_init_script, which was a workaround for a very old
104 bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
105 they aren't going to be convinced now (closes: #214182).
106 * Remove support for upgrading directly from ssh-nonfree.
107 * Remove lots of maintainer script support for direct upgrades from
108 pre-etch (three releases before current stable).
109 * Add #DEBHELPER# tokens to openssh-client.postinst and
110 openssh-server.postinst.
111 * Replace old manual conffile handling code with dpkg-maintscript-helper,
112 via dh_installdeb.
113 * Switch to new unified layout for Upstart jobs as documented in
114 https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
115 checks for a running Upstart, and we now let dh_installinit handle most
116 of the heavy lifting in maintainer scripts. Ubuntu users should be
117 essentially unaffected except that sshd may no longer start
118 automatically in chroots if the running Upstart predates 0.9.0; but the
119 main goal is simply not to break when openssh-server is installed in a
120 chroot.
121 * Remove the check for vulnerable host keys; this was first added five
122 years ago, and everyone should have upgraded through a version that
123 applied these checks by now. The ssh-vulnkey tool and the blacklisting
124 support in sshd are still here, at least for the moment.
125 * This removes the last of our uses of debconf (closes: #221531).
126 * Use the pam_loginuid session module (thanks, Laurent Bigonville; closes:

129 Laurent Bigonville; closes: #679458).

131 binary packages, as intended since 1:6.1p1-2.

399 - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
400 and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
401 offer better performance than plain DH and DSA at the same equivalent
402 symmetric key length, as well as much shorter keys.
403 - sftp(1)/sftp-server(8): add a protocol extension to support a hard
404 link operation. It is available through the "ln" command in the
405 client. The old "ln" behaviour of creating a symlink is available
406 using its "-s" option or through the preexisting "symlink" command.
407 - scp(1): Add a new -3 option to scp: Copies between two remote hosts
408 are transferred through the local host (closes: #508613).
409 - ssh(1): "atomically" create the listening mux socket by binding it on
410 a temporary name and then linking it into position after listen() has
411 succeeded. This allows the mux clients to determine that the server
412 socket is either ready or stale without races (closes: #454784).
413 Stale server sockets are now automatically removed (closes: #523250).
414 - ssh(1): install a SIGCHLD handler to reap expired child process
415 (closes: #594687).
416 - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
417 temporary directories (closes: #357469, although only if you arrange
418 for ssh-agent to actually see $TMPDIR since the setgid bit will cause
419 it to be stripped off).
420 * Update to current GSSAPI patch from
421 http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
422 - Add GSSAPIServerIdentity option.
423 * Generate ECDSA host keys on fresh installations. Upgraders who wish to
424 add such host keys should manually add 'HostKey
425 /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
426 -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
427 * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
428 * Backport SELinux build fix from CVS.
429 * Rearrange selinux-role.patch so that it links properly given this

497 rather than being user-private groups (closes: #581697).

547
548 * New upstream release (LP: #535029).
549 - After a transition period of about 10 years, this release disables SSH
550 protocol 1 by default. Clients and servers that need to use the
551 legacy protocol must explicitly enable it in ssh_config / sshd_config
552 or on the command-line.
553 - Remove the libsectok/OpenSC-based smartcard code and add support for
554 PKCS#11 tokens. This support is enabled by default in the Debian
555 packaging, since it now doesn't involve additional library
556 dependencies (closes: #231472, LP: #16918).
557 - Add support for certificate authentication of users and hosts using a
558 new, minimal OpenSSH certificate format (closes: #482806).
559 - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
560 - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
561 package, this overlaps with the key blacklisting facility added in
562 openssh 1:4.7p1-9, but with different file formats and slightly
563 different scopes; for the moment, I've roughly merged the two.)
564 - Various multiplexing improvements, including support for requesting
565 port-forwardings via the multiplex protocol (closes: #360151).
566 - Allow setting an explicit umask on the sftp-server(8) commandline to
567 override whatever default the user has (closes: #496843).
568 - Many sftp client improvements, including tab-completion, more options,
569 and recursive transfer support for get/put (LP: #33378). The old
570 mget/mput commands never worked properly and have been removed
571 (closes: #270399, #428082).
572 - Do not prompt for a passphrase if we fail to open a keyfile, and log
573 the reason why the open failed to debug (closes: #431538).
574 - Prevent sftp from crashing when given a "-" without a command. Also,
575 allow whitespace to follow a "-" (closes: #531561).
576
577 * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
578 patches apply with offsets.
579 * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
580 we're using a source format that permits this, rather than messing
581 around with uudecode.
582 * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
583 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
584 mechanism was removed due to a serious security hole, and since these
585 versions of ssh-krb5 are no longer security-supported by Debian I don't
586 think there's any point keeping client compatibility for them.
587 * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
588 * Hardcode the location of xauth to /usr/bin/xauth rather than
589 /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
590 xauth no longer depends on x11-common, so we're no longer guaranteed to
591 have the /usr/bin/X11 symlink available. I was taking advantage of the
592 /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
593 enough in the past now that it's probably safe to just use /usr/bin.
594 * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
595 itself non-OOM-killable, and doesn't require configuration to avoid log
596 spam in virtualisation containers (closes: #555625).
597 * Drop Debian-specific removal of OpenSSL version check. Upstream ignores
598 the two patchlevel nybbles now, which is sufficient to address the
599 original reason this change was introduced, and it appears that any
600 change in the major/minor/fix nybbles would involve a new libssl package
601 name. (We'd still lose if the status nybble were ever changed, but that
602 would mean somebody had packaged a development/beta version rather than
603 a proper release, which doesn't appear to be normal practice.)
604 * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
605 introduced to match the behaviour of non-free SSH, in which -q does not
606 suppress fatal errors, but matching the behaviour of OpenSSH upstream is
607 much more important nowadays. We no longer document that -q does not
608 suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
609 "LogLevel QUIET" in sshd_config on upgrade.
610 * Policy version 3.8.4:
611 - Add a Homepage field.

646 - Do not fall back to adding keys without constraints (ssh-add -c / -t
647 ...) when the agent refuses the constrained add request. This was a

649 just adds risk now (LP: #209447).
650 * Drop change from 1:3.8p1-3 to avoid setresuid() and setresgid() system
651 calls. This only applied to Linux 2.2, which it's no longer feasible to
652 run anyway (see 1:5.2p1-2 changelog).

662 in sshd dying (LP: #497781).
663 - Output a debug if we can't open an existing keyfile (LP: #505301).
664 * Use host compiler for ssh-askpass-gnome when cross-compiling.
665 * Don't run tests when cross-compiling.
666 * Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file
667 descriptor passing when running on Linux 2.0. The previous stable
668 release of Debian dropped support for Linux 2.4, let alone 2.0, so this

682 - Change the default cipher order to prefer the AES CTR modes and the
683 revised "arcfour256" mode to CBC mode ciphers that are susceptible to
684 CPNI-957037 "Plaintext Recovery Attack Against SSH".
685 - Add countermeasures to mitigate CPNI-957037-style attacks against the
686 SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
687 packet length or Message Authentication Code, ssh/sshd will continue
688 reading up to the maximum supported packet length rather than
689 immediately terminating the connection. This eliminates most of the
690 known differences in behaviour that leaked information about the
691 plaintext of injected data which formed the basis of this attack
692 (closes: #506115, LP: #379329).
693 - ForceCommand directive now accepts commandline arguments for the
694 internal-sftp server (closes: #524423, LP: #362511).
695 - Add AllowAgentForwarding to available Match keywords list (closes:
696 #540623).
697 - Make ssh(1) send the correct channel number for
698 SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
699 avoid triggering 'Non-public channel' error messages on sshd(8) in
700 openssh-5.1.
701 - Avoid printing 'Non-public channel' warnings in sshd(8), since the
702 ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a
703 behaviour introduced in openssh-5.1; closes: #496017).
704 - Disable nonfunctional ssh(1) ~C escape handler in multiplex slave
705 connections (closes: #507541).

838 * New upstream release (closes: #474301). Important changes not previously
839 backported to 4.7p1:
840 - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
841 + Added chroot(2) support for sshd(8), controlled by a new option
842 "ChrootDirectory" (closes: #139047, LP: #24777).
843 + Linked sftp-server(8) into sshd(8). The internal sftp server is used
844 when the command "internal-sftp" is specified in a Subsystem or
845 ForceCommand declaration. When used with ChrootDirectory, the
846 internal sftp server requires no special configuration of files
847 inside the chroot environment.
848 + Added a protocol extension method "posix-rename@openssh.com" for
849 sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
850 prefers this if available (closes: #308561).
851 + Removed the fixed limit of 100 file handles in sftp-server(8).
852 + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
853 keys when in inetd mode and protocol 2 connections are negotiated.
854 This speeds up protocol 2 connections to inetd-mode servers that
855 also allow Protocol 1.
856 + Accept the PermitRootLogin directive in a sshd_config(5) Match
857 block. Allows for, e.g. permitting root only from the local network.
858 + Reworked sftp(1) argument splitting and escaping to be more
859 internally consistent (i.e. between sftp commands) and more
860 consistent with sh(1). Please note that this will change the
861 interpretation of some quoted strings, especially those with
862 embedded backslash escape sequences.
863 + Support "Banner=none" in sshd_config(5) to disable sending of a
864 pre-login banner (e.g. in a Match block).
865 + ssh(1) ProxyCommands are now executed with $SHELL rather than
866 /bin/sh.
867 + ssh(1)'s ConnectTimeout option is now applied to both the TCP
868 connection and the SSH banner exchange (previously it just covered
869 the TCP connection). This allows callers of ssh(1) to better detect
870 and deal with stuck servers that accept a TCP connection but don't
871 progress the protocol, and also makes ConnectTimeout useful for
872 connections via a ProxyCommand.
873 + scp(1) incorrectly reported "stalled" on slow copies (closes:
874 #140828).
875 + scp(1) date underflow for timestamps before epoch.
876 + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
877 instead of the current standard RRSIG.
878 + Correctly drain ACKs when a sftp(1) upload write fails midway,
879 avoids a fatal() exit from what should be a recoverable condition.
880 + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
881 hostname") to not include any IP address in the data to be hashed.
882 + Make ssh(1) skip listening on the IPv6 wildcard address when a
883 binding address of 0.0.0.0 is used against an old SSH server that
884 does not support the RFC4254 syntax for wildcard bind addresses.
885 + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
886 already done for X11/TCP forwarding sockets (closes: #439661).
887 + Fix FD leak that could hang a ssh(1) connection multiplexing master.
888 + Make ssh(1) -q option documentation consistent with reality.
889 + Fixed sshd(8) PAM support not calling pam_session_close(), or
890 failing to call it with root privileges (closes: #372680).
891 + Fix activation of OpenSSL engine support when requested in configure
892 (LP: #119295).
893 + Cache SELinux status earlier so we know if it's enabled after a
894 chroot (LP: #237557).
895 - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
896 + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
897 and ssh-keygen(1). Visual fingerprint display is controlled by a new
898 ssh_config(5) option "VisualHostKey". The intent is to render SSH
899 host keys in a visual form that is amenable to easy recall and
900 rejection of changed host keys.
901 + sshd_config(5) now supports CIDR address/masklen matching in "Match
902 address" blocks, with a fallback to classic wildcard matching.
903 + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
904 from="..." restrictions, also with a fallback to classic wildcard
905 matching.
906 + Added an extended test mode (-T) to sshd(8) to request that it write
907 its effective configuration to stdout and exit. Extended test mode
908 also supports the specification of connection parameters (username,
909 source address and hostname) to test the application of
910 sshd_config(5) Match rules.
911 + ssh(1) now prints the number of bytes transferred and the overall
912 connection throughput for SSH protocol 2 sessions when in verbose
913 mode (previously these statistics were displayed for protocol 1
914 connections only).
915 + sftp-server(8) now supports extension methods statvfs@openssh.com
916 and fstatvfs@openssh.com that implement statvfs(2)-like operations.
917 + sftp(1) now has a "df" command to the sftp client that uses the
918 statvfs@openssh.com to produce a df(1)-like display of filesystem
919 space and inode utilisation (requires statvfs@openssh.com support on
920 the server).
921 + Added a MaxSessions option to sshd_config(5) to allow control of the
922 number of multiplexed sessions supported over a single TCP
923 connection. This allows increasing the number of allowed sessions
924 above the previous default of 10, disabling connection multiplexing
925 (MaxSessions=1) or disallowing login/shell/subsystem sessions
926 entirely (MaxSessions=0).
927 + Added a no-more-sessions@openssh.com global request extension that
928 is sent from ssh(1) to sshd(8) when the client knows that it will
929 never request another session (i.e. when session multiplexing is
930 disabled). This allows a server to disallow further session requests
931 and terminate the session in cases where the client has been
932 hijacked.
933 + ssh-keygen(1) now supports the use of the -l option in combination
934 with -F to search for a host in ~/.ssh/known_hosts and display its
935 fingerprint.
936 + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
937 "rsa1" (LP: #129794).
938 + Added an AllowAgentForwarding option to sshd_config(8) to control
939 whether authentication agent forwarding is permitted. Note that this
940 is a loose control, as a client may install their own unofficial
941 forwarder.
942 + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
943 receiving network data, resulting in a ~10% speedup.
944 + ssh(1) and sshd(8) will now try additional addresses when connecting
945 to a port forward destination whose DNS name resolves to more than
946 one address. The previous behaviour was to try the only first
947 address and give up if that failed.
948 + ssh(1) and sshd(8) now support signalling that channels are
949 half-closed for writing, through a channel protocol extension
950 notification "eow@openssh.com". This allows propagation of closed
951 file descriptors, so that commands such as "ssh -2 localhost od
952 /bin/ls | true" do not send unnecessary data over the wire.
953 + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
954 from 768 to 1024 bits.
955 + When ssh(1) has been requested to fork after authentication ("ssh
956 -f") with ExitOnForwardFailure enabled, delay the fork until after
957 replies for any -R forwards have been seen. Allows for robust
958 detection of -R forward failure when using -f.
959 + "Match group" blocks in sshd_config(5) now support negation of
960 groups. E.g. "Match group staff,!guests".
961 + sftp(1) and sftp-server(8) now allow chmod-like operations to set
962 set[ug]id/sticky bits.
963 + The MaxAuthTries option is now permitted in sshd_config(5) match
964 blocks.
965 + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
966 that are available to a primary connection.
967 + ssh(1) connection multiplexing will now fall back to creating a new
968 connection in most error cases (closes: #352830).
969 + Make ssh(1) deal more gracefully with channel requests that fail.
970 Previously it would optimistically assume that requests would always
971 succeed, which could cause hangs if they did not (e.g. when the
972 server runs out of file descriptors).
973 + ssh(1) now reports multiplexing errors via the multiplex slave's
974 stderr where possible (subject to LogLevel in the mux master).
975 + Fixed an UMAC alignment problem that manifested on Itanium
976 platforms.
977 * Remove our local version of moduli(5) now that there's one upstream.
978 * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
979 * Add lintian overrides for empty /usr/share/doc/openssh-client
980 directories in openssh-server and ssh (necessary due to being symlink
981 targets).
982 * Merge from Ubuntu:

1220 creation of an untrusted cookie fails; found and fixed by Jan Pechanec
1221 (closes: #444738).
1222 - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
1223 installations are unchanged.
1224 - The SSH channel window size has been increased, and both ssh(1)
1225 sshd(8) now send window updates more aggressively. These improves
1226 performance on high-BDP (Bandwidth Delay Product) networks.
1227 - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
1228 saves 2 hash calls per packet and results in 12-16% speedup for
1229 arcfour256/hmac-md5.
1230 - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
1231 "umac-64@openssh.com". UMAC-64 has been measured to be approximately
1232 20% faster than HMAC-MD5.
1233 - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
1234 error when the ExitOnForwardFailure option is set.
1235 - ssh(1) returns a sensible exit status if the control master goes away
1236 without passing the full exit status.
1237 - When using a ProxyCommand in ssh(1), set the outgoing hostname with
1238 gethostname(2), allowing hostbased authentication to work.
1239 - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
1240 - Encode non-printing characters in scp(1) filenames. These could cause
1241 copies to be aborted with a "protocol error".
1242 - Handle SIGINT in sshd(8) privilege separation child process to ensure
1243 that wtmp and lastlog records are correctly updated.
1244 - Report GSSAPI mechanism in errors, for libraries that support multiple
1245 mechanisms.
1246 - Improve documentation for ssh-add(1)'s -d option.
1247 - Rearrange and tidy GSSAPI code, removing server-only code being linked
1248 into the client.
1249 - Delay execution of ssh(1)'s LocalCommand until after all forwardings
1250 have been established.
1251 - In scp(1), do not truncate non-regular files.
1252 - Improve exit message from ControlMaster clients.
1253 - Prevent sftp-server(8) from reading until it runs out of buffer space,
1254 whereupon it would exit with a fatal error (closes: #365541).
1255 - pam_end() was not being called if authentication failed

1368
1369 * New upstream release (closes: #395507, #397961, #420035). Important
1370 changes not previously backported to 4.3p2:
1371 - 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
1372 + On portable OpenSSH, fix a GSSAPI authentication abort that could be
1373 used to determine the validity of usernames on some platforms.
1374 + Implemented conditional configuration in sshd_config(5) using the
1375 "Match" directive. This allows some configuration options to be
1376 selectively overridden if specific criteria (based on user, group,
1377 hostname and/or address) are met. So far a useful subset of
1378 post-authentication options are supported and more are expected to
1379 be added in future releases.
1380 + Add support for Diffie-Hellman group exchange key agreement with a
1381 final hash of SHA256.
1382 + Added a "ForceCommand" directive to sshd_config(5). Similar to the
1383 command="..." option accepted in ~/.ssh/authorized_keys, this forces
1384 the execution of the specified command regardless of what the user
1385 requested. This is very useful in conjunction with the new "Match"
1386 option.
1387 + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
1388 permitopen="..." authorized_keys option, allowing fine-grained
1389 control over the port-forwardings that a user is allowed to
1390 establish.
1391 + Add optional logging of transactions to sftp-server(8).
1392 + ssh(1) will now record port numbers for hosts stored in
1393 ~/.ssh/known_hosts when a non-standard port has been requested
1394 (closes: #50612).
1395 + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
1396 non-zero exit code) when requested port forwardings could not be
1397 established.
1398 + Extend sshd_config(5) "SubSystem" declarations to allow the
1399 specification of command-line arguments.
1400 + Replacement of all integer overflow susceptible invocations of
1401 malloc(3) and realloc(3) with overflow-checking equivalents.
1402 + Many manpage fixes and improvements.
1403 + Add optional support for OpenSSL hardware accelerators (engines),
1404 enabled using the --with-ssl-engine configure option.
1405 + Tokens in configuration files may be double-quoted in order to
1406 contain spaces (closes: #319639).
1407 + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
1408 session exits very quickly (closes: #307890).
1409 + Fix some incorrect buffer allocation calculations (closes: #410599).
1410 + ssh-add doesn't ask for a passphrase if key file permissions are too
1411 liberal (closes: #103677).
1412 + Likewise, ssh doesn't ask either (closes: #99675).
1413 - 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
1414 + sshd now allows the enabling and disabling of authentication methods
1415 on a per user, group, host and network basis via the Match directive
1416 in sshd_config.
1417 + Fixed an inconsistent check for a terminal when displaying scp
1418 progress meter (closes: #257524).
1419 + Fix "hang on exit" when background processes are running at the time
1420 of exit on a ttyful/login session (closes: #88337).
1421 * Update to current GSSAPI patch from
1422 http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
1423 install ChangeLog.gssapi.
1424 * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
1425 * Use LSB functions in init scripts, and add an LSB-style header (partly
1426 from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
1427 * Move init script start links to S16, move rc1 stop link to K84, and
1428 remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
1429 closes: #122188).
1430 * Emit a slightly more informative message from the init script if
1431 /dev/null has somehow become not a character device (closes: #369964).
1432 * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
1433 * Merge from Ubuntu:
1434 - Build position-independent executables (only for debs, not for udebs)
1435 to take advantage of address space layout randomisation.
1436 - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to
1437 the default path.
1438 * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
1439 openssh-client dependency.

1510 * Drop versioning on ssh/ssh-krb5 Replaces, as otherwise it isn't

1512 * Make GSSAPICleanupCreds a compatibility alias for
1513 GSSAPICleanupCredentials. Mark GSSUseSessionCCache and
1514 GSSAPIUseSessionCredCache as known-but-unsupported options, and migrate
1515 away from them on upgrade.
1516 * It turns out that the people who told me that removing a conffile in the
1517 preinst was sufficient to have dpkg replace it without prompting when
1518 moving a conffile between packages were very much mistaken. As far as I
1519 can tell, the only way to do this reliably is to write out the desired
1520 new text of the conffile in the preinst. This is gross, and requires
1521 shipping the text of all conffiles in the preinst too, but there's
1522 nothing for it. Fortunately this nonsense is only required for smooth
1523 upgrades from sarge.

1645 of attacker-specified commands with the privilege of the user running
1646 scp (closes: #349645).
1647 - Add support for tunneling arbitrary network packets over a connection
1648 between an OpenSSH client and server via tun(4) virtual network
1649 interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
1650 between the client and server providing real network connectivity at
1651 layer 2 or 3. This feature is experimental.
1652 - Reduce default key length for new DSA keys generated by ssh-keygen
1653 back to 1024 bits. DSA is not specified for longer lengths and does
1654 not fully benefit from simply making keys longer. As per FIPS 186-2
1655 Change Notice 1, ssh-keygen will refuse to generate a new DSA key
1656 smaller or larger than 1024 bits.
1657 - Fixed X forwarding failing to start when the X11 client is executed in
1658 background at the time of session exit.
1659 - Change ssh-keygen to generate a protocol 2 RSA key when invoked
1660 without arguments (closes: #114894).
1661 - Fix timing variance for valid vs. invalid accounts when attempting
1662 Kerberos authentication.
1663 - Ensure that ssh always returns code 255 on internal error
1664 (closes: #259865).
1665 - Cleanup wtmp files on SIGTERM when not using privsep.
1666 - Set SO_REUSEADDR on X11 listeners to avoid problems caused by
1667 lingering sockets from previous session (X11 applications can
1668 sometimes not connect to 127.0.0.1:60xx) (closes:
1669 https://launchpad.net/bugs/25528).
1670 - Ensure that fds 0, 1 and 2 are always attached in all programs, by
1671 duping /dev/null to them if necessary.
1672 - Xauth list invocation had bogus "." argument.
1673 - Remove internal assumptions on key exchange hash algorithm and output
1674 length, preparing OpenSSH for KEX methods with alternate hashes.
1675 - Ignore junk sent by a server before it sends the "SSH-" banner.
1676 - Many manual page improvements.
1677 - Lots of cleanups, including fixes to memory leaks on error paths and
1678 possible crashes.
1679 * Update to current GSSAPI patch from
1680 http://www.sxw.org.uk/computing/patches/openssh-4.3p2-gsskex-20060223.patch
1681 (closes: #352042).
1682 * debian/rules: Resynchronise CFLAGS with that generated by configure.
1683 * Restore pam_nologin to /etc/pam.d/ssh; sshd no longer checks this itself
1684 when PAM is enabled, but relies on PAM to do it.
1685 * Rename KeepAlive to TCPKeepAlive in default sshd_config
1686 (closes: #349896).
1687 * Rephrase ssh/new_config and ssh/encrypted_host_key_but_no_keygen debconf
1688 templates to make boolean short descriptions end with a question mark
1689 and to avoid use of the first person.

1787 port forwardings when no listen address was explicitly specified
1788 (closes: #326065).
1789 - SECURITY (CAN-2005-2798): Fix improper delegation of GSSAPI
1790 credentials. This code is only built in openssh-krb5, not openssh, but
1791 I mention the CVE reference here anyway for completeness.
1792 - Add a new compression method ("Compression delayed") that delays zlib
1793 compression until after authentication, eliminating the risk of zlib
1794 vulnerabilities being exploited by unauthenticated users. Note that
1795 users of OpenSSH versions earlier than 3.5 will need to disable
1796 compression on the client or set "Compression yes" (losing this
1797 security benefit) on the server.
1798 - Increase the default size of new RSA/DSA keys generated by ssh-keygen
1799 from 1024 to 2048 bits (closes: #181162).
1800 - Many bugfixes and improvements to connection multiplexing.

1805 * Set X11Forwarding to yes in the default sshd_config (new installs only).
1806 At least when X11UseLocalhost is turned on, which is the default, the
1807 security risks of using X11 forwarding are risks to the client, not to

1857 machine is not SELinux aware). By and large, the changes made should
1858 have no effect unless the rules file calls --with-selinux; and even
1859 then there should be no performance hit for machines not actively
1860 running SELinux.
1861 - Modified the preinst and postinst to call restorecon to set the

1864 may want to also include pam_selinux.so.

1886 * Since ssh-keysign isn't used by default (you need to set

1927 (closes: #87253, #192206).

1930 managing known_hosts files, which understand hashing.
1931 - sftp supports command history and editing support using libedit
1932 (closes: #287013).
1933 - Have scp and sftp wait for the spawned ssh to exit before they exit
1934 themselves, allowing ssh to restore terminal modes (closes: #257130).
1935 - Improved the handling of bad data in authorized_keys files,
1936 eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
1937 in keys only produce errors in auth.log now (closes: #220726).

2062 * Split the ssh binary package into openssh-client and openssh-server
2063 (closes: #39741). openssh-server depends on openssh-client for some
2064 common functionality; it didn't seem worth creating yet another package
2065 for this. openssh-client is priority standard, openssh-server optional.
2066 * New transitional ssh package, priority optional, depending on
2067 openssh-client and openssh-server. May be removed once nothing depends
2068 on it.
2069 * When upgrading from ssh to openssh-{client,server}, it's very difficult
2070 for the maintainer scripts to find out what version we're upgrading from
2071 without dodgy dpkg hackery. I've therefore taken the opportunity to move
2072 a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
2073 and ssh/user_environment_tell.
2074 * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
2075 happens even though we don't know what version we're upgrading from.
2076 * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
2077 (until sarge+2) it's still honoured to avoid breaking existing
2078 configurations, but the right approach is now to remove the
2079 openssh-server package if you don't want to run the server. Add a NEWS
2080 item to that effect.

2249 - New PAM implementation based on that in FreeBSD. This runs PAM session
2250 modules before dropping privileges (closes: #132681, #150968).
2251 - Since PAM session modules are run as root, we can turn pam_limits back
2252 on by default, and it no longer spits out "Operation not permitted" to
2253 syslog (closes: #171673).
2254 - Password expiry works again (closes: #153235).
2255 - 'ssh -q' suppresses login banner (closes: #134589).
2256 - sshd doesn't lie to PAM about invalid usernames (closes: #157078).
2257 - ssh-add prints key comment on each prompt (closes: #181869).
2258 - Punctuation formatting fixed in man pages (closes: #191131).
2259 - EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
2260 * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
2261 than this, to maintain the standard Debian sshd configuration.
2262 * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
2263 sshd_config on upgrade. Neither option is supported any more.
2264 * Privilege separation and PAM are now properly supported together, so
2265 remove both debconf questions related to them and simply set it
2266 unconditionally in newly generated sshd_config files (closes: #228838).
2267 * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
2268 compatibility alias. The semantics differ slightly, though; see
2269 ssh_config(5) for details.
2270 * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
2271 documented in ssh_config(5), it's not as good as the SSH2 version.
2272 * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and
2273 -D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary.
2274 * Update config.guess and config.sub from autotools-dev 20040105.1.

2426 * Compile with -fno-builtin-log for now, otherwise gcc-3.3 complains

2437 (closes: #106037).
2438 * Put newlines after full stops in man page documentation for
2439 ProtocolKeepAlives and SetupTimeOut.
2440 * Policy version 3.5.9: support DEB_BUILD_OPTIONS=noopt, build
2441 gnome-ssh-askpass with -g and -Wall flags.
2442 * Really ask ssh/new_config debconf question before trying to fetch its

2444 * On purge, remove only the files we know about in /etc/ssh rather than
2445 the whole thing, and remove the directory if that leaves it empty
2446 (closes: #176679).
2447 * ssh has depended on debconf for some time now with no complaints, so:
2448 - Simplify the postinst by relying on debconf being present. (The absent
2449 case was buggy anyway.)
2450 - Get rid of "if you have not installed debconf" text in README.Debian,
2451 and generally update the "/usr/bin/ssh not SUID" entry.
2452 * More README.Debian work:
2453 - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
2454 make it easier for people to find the former. The upgrade issues
2455 should probably be sorted by version somehow.
2456 - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).
2457 * Fix setting of IP flags for interactive sessions (upstream bug #541).

2474 - As such, it should now be safe to remove --with-ipv4-default, so
2475 starting sshd with -6 is no longer necessary (closes: #79861 and lots
2476 of other merged bugs).
2477 - ssh-copy-id prints usage when run without arguments (closes: #71376).
2478 - scp exits 1 if ssh fails (closes: #138400).
2479 - sshd writes to utmp's ut_addr_v6 field in IPv6 mode (closes: #167867).
2480 - 'ssh-add -c' causes ssh-agent to ask the user each time a key is used
2481 (closes: #109795).

2491 /usr/local/sbin (closes: #128235, #151267). Using login.defs would be
2492 nice, but that belongs to another package. Without a defined API to
2493 retrieve its settings, parsing it is off-limits.
2494 * Build ssh-askpass-gnome with GNOME 2. The source package should still
2495 support building on stable with GNOME 1, using the alternate
2496 libgnome-dev build-dependency (thanks, Colin Walters; closes: #167582).

2503 than ssh (closes: #121103, #151666). Fix alternative removal to match;
2504 previously it was completely wrong anyway.
2505 * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
2506 question's default using that information, rather than using debconf as
2507 a registry. Other solutions may be better in the long run, but this is
2508 at least correct (thanks, Matthew Woodcraft; closes: #84725).
2509 * Stop using pam_lastlog, as it doesn't currently work well as a session
2510 module when privilege separation is enabled; it can usually read
2511 /var/log/lastlog but can't write to it. Instead, just use sshd's
2512 built-in support, already enabled by default (closes: #151297, #169938).
2513 * Use 'ssh-keygen -q' rather than redirecting output to /dev/null.
2514 * Add a "this may take some time" warning when creating host keys on
2515 installation (part of #110094).
2516 * When restarting via the init script, check for sshd_not_to_be_run after
2517 stopping sshd (idea from Tomas Pospisek; closes: #149850).
2518 * Append /usr/sbin:/sbin to the init script's $PATH, just in case of
2519 strangeness (closes: #115138).

2535 * Replace db_text with db_input throughout debian/config. (db_text has

2537 * Warn about PermitUserEnvironment on upgrade (closes: #167895).

2568 - ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys
2569 are deprecated for security reasons and will eventually go away. For
2570 now they can be re-enabled by setting 'PermitUserEnvironment yes' in
2571 sshd_config.
2572 - ssh-agent is installed setgid to prevent ptrace() attacks. The group
2573 actually doesn't matter, as it drops privileges immediately, but to
2574 avoid confusion the postinst creates a new 'ssh' group for it.
2575 * Obsolete patches:
2576 - Solar Designer's privsep+compression patch for Linux 2.2 (see
2577 1:3.3p1-0.0woody1).
2578 - Hostbased auth ssh-keysign backport (see 1:3.4p1-4).

3369 oldssh -> openssh preinst fails due to upgrade_to_openssh=false
3370 -> ssh-nonfree -> openssh. Without these, debconf remembered
3371 the old answer, config didn't force asking it, and preinst always
3372 aborted (closes: #56596, #57782)
3373 * Moved setting upgrade_to_openssh isdefault flag to the place
3374 where preinst would abort. This means no double question to most
3375 users, people who currently suffer from "can't upgrade" may need
3376 to run apt-get install ssh twice. Did not do the same for
3377 use_old_init_script, as the situation is a bit different, and
3378 less common (closes: #54010, #56224)

3380 preinst, added warning for non-existant ssh-keygen in config. This

21Description: secure shell (SSH) client, for secure access to remote machines
22 This is the portable version of OpenSSH, a free implementation of
23 the Secure Shell protocol as specified by the IETF secsh working
24 group.
25 .
26 Ssh (Secure Shell) is a program for logging into a remote machine
27 and for executing commands on a remote machine.
28 It provides secure encrypted communications between two untrusted
29 hosts over an insecure network. X11 connections and arbitrary TCP/IP
30 ports can also be forwarded over the secure channel.
31 It can be used to provide applications with a secure communication
32 channel.
33 .
34 This package provides the ssh, scp and sftp clients, the ssh-agent
35 and ssh-add programs to make public key authentication more convenient,
36 and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
37 .
38 In some countries it may be illegal to use any encryption at all
39 without a special permit.
40 .
41 ssh replaces the insecure rsh, rcp and rlogin programs, which are
42 obsolete for most purposes.

92 client and server, which now support GSSAPI natively. It will add the
93 necessary GSSAPI options to the server configuration file. You can
94 remove it once the upgrade is complete and nothing depends on it.

10The Debian-specific parts of the package were initially derived from the
11original ssh package, which has since been renamed as ssh-nonfree.

13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL.
15
16In addition, as a special exception, Matthew Vernon gives permission
17to link the code of the Debian patch with any version of the OpenSSH
18code which is distributed under a license identical to that listed in
19the included Copyright file, and distribute linked combinations
20including the two. You must obey the GNU General Public License in
21all respects for all of the code used other than OpenSSH. If you

26The upstream source for this package is a combination of the ssh
27branch that is being maintained by the OpenBSD team (starting from
28the last version of SSH that was distributed under a free license),
29and porting work by Damien Miller <damien@ibs.com.au> to get it
30working on Linux. Other people also contributed to this, and are

79OpenSSH provides end-to-end encrypted replacement of applications such as
80telnet, rlogin, and ftp.
81Unlike these legacy applications, OpenSSH never passes anything
82(including username and password) over the wire in unencrypted form, and
83provides host authentication, to verify that you really are talking to
84the system that you think you are and that no one else can take over
85that session.
86
87<p>
88The OpenSSH suite includes the
89<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a>
90program which replaces rlogin and telnet, and
91<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a>
92which replaces
93<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rcp&amp;sektion=1">rcp(1)</a> and
94<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ftp&amp;sektion=1">ftp(1)</a>.
95OpenSSH has also added
96<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> and
97<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a>
98which implement an easier solution for file-transfer. This is based upon the
99<a href="http://www.openssh.org/txt/draft-ietf-secsh-filexfer-02.txt">secsh-filexfer</a> IETF draft.
100
101
102<p><strong>OpenSSH consists of a number of programs.</strong>
103
104<ul>
105<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a> - Server program run on the server machine. This listens for connections from client machines, and whenever it receives a connection, it performs authentication and starts serving the client.
106Its behaviour is controlled by the config file <i><a
107href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
108sshd_config(5)</a></i>.
109<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> - This is the client program used to log into another machine or to execute commands on the other machine. <i>slogin</i> is another name for this program.
110Its behaviour is controlled by the global config file <i><a
111href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
112ssh_config(5)</a></i> and individual users' <i>$HOME/.ssh/config</i> files.
113<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=scp&amp;sektion=1">scp(1)</a> - Securely copies files from one machine to another.
114<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a> - Used to create Pubkey Authentication (RSA or DSA) keys (host keys and user authentication keys).
115<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-agent&amp;sektion=1">ssh-agent(1)</a> - Authentication agent. This can be used to hold RSA keys for authentication.
116<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-add&amp;sektion=1">ssh-add(1)</a> - Used to register new keys with the agent.
117<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp-server&amp;sektion=8">sftp-server(8)</a> - SFTP server subsystem.
118<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sftp&amp;sektion=1">sftp(1)</a> - Secure file transfer program.
119<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keyscan&amp;sektion=1">ssh-keyscan(1)</a> - gather ssh public keys.
120<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign&amp;sektion=8">ssh-keysign(8)</a> - ssh helper program for hostbased authentication.
121</ul>
122
123<h3>Downloading</h3>
124
125<p>
126The most recent version of OpenSSH is included with the current
127distribution of <a href="http://www.openbsd.org/">OpenBSD</a>, and
128installed as part of a basic install.
129
130<p>
131Today, most other operating systems include some version of OpenSSH
132(often re-badged or privately labeled), so most users can immediately
133use it.
134However, sometimes the included versions are quite old, and missing
135features of the current release of OpenSSH, and you may wish to install
136the current version, or install it on one of the few OSs that lacked it,
137and where the OS publisher does not make a modern version available.
138You may also wish to use OpenSSH on your embedded application.
139
140<p>
141Non-OpenBSD users will want to download, compile and install the
142multi-platform <a href="http://www.openssh.org/portable.html">Portable</a> distribution from a
143<a href="http://www.openssh.org/portable.html#mirrors">mirror</a> near you.

145
146<h2><a name= "1.2">1.2 - Why should it be used?</a></h2>
147
148<p>
149OpenSSH is a suite of tools to help secure your network
150connections. Here is a list of features:
151
152
153<ul>
154 <li>Strong authentication. Closes several security holes (e.g., IP, routing, and DNS spoofing).
155 <li>Improved privacy. All communications are automatically and transparently encrypted.
156 <li>Secure X11 sessions. The program automatically sets DISPLAY on the server machine, and forwards any X11 connections over the secure channel.
157 <li>Arbitrary TCP/IP ports can be redirected through the encrypted channel in both directions (e.g., for e-cash transactions).
158 <li>No retraining needed for normal users.
159 <li>Never trusts the network. Minimal trust on the remote side of the connection. Minimal trust on domain name servers. Pure RSA authentication never trusts anything but the private key.
160 <li>Client RSA-authenticates the server machine in the beginning of every connection to prevent trojan horses (by routing or DNS spoofing) and man-in-the-middle attacks, and the server RSA-authenticates the client machine before accepting <i>.rhosts</i> or <i>/etc/hosts.equiv</i> authentication (to prevent DNS, routing, or IP-spoofing).
161 <li>Host authentication key distribution can be centrally by the administration, automatically when the first connection is made to a machine.
162 <li>Any user can create any number of user authentication RSA keys for his/her own use.
163 <li>The server program has its own server RSA key which is automatically regenerated every hour.
164 <li>An authentication agent, running in the user's laptop or local workstation, can be used to hold the user's RSA authentication keys.
165 <li>The software can be installed and used (with restricted functionality) even without root privileges.
166 <li>The client is customizable in system-wide and per-user configuration files.
167 <li>Optional compression of all data with gzip (including forwarded X11 and TCP/IP port data), which may result in significant speedups on slow connections.
168 <li>Complete replacement for rlogin, rsh, and rcp.
169</ul>
170
171<p>
172Currently, almost all communications in computer networks are done
173without encryption. As a consequence, anyone who has access to any
174machine connected to the network can listen in on any communication.
175This is being done by hackers, curious administrators, employers,
176criminals, industrial spies, and governments. Some networks leak off
177enough electromagnetic radiation that data may be captured even from a
178distance.
179
180
181<p>
182When you log in, your password goes in the network in plain
183text. Thus, any listener can then use your account to do any evil he
184likes. Many incidents have been encountered worldwide where crackers
185have started programs on workstations without the owner's knowledge
186just to listen to the network and collect passwords. Programs for
187doing this are available on the Internet, or can be built by a
188competent programmer in a few hours.

241<p>
242The OpenSSH developers have tried very hard to keep OpenSSH free of any
243patent or copyright problems. To do this, some options had to be
244stripped from OpenSSH. Namely support for patented algorithms.
245
246<p>
247OpenSSH does not support any patented transport algorithms. In SSH1 mode,
248only 3DES and Blowfish are available options. In SSH2 mode, only 3DES,
249Blowfish, CAST128, Arcfour and AES can be selected.
250The patented IDEA algorithm is not supported.
251
252<p>
253OpenSSH provides support for both SSH1 and SSH2 protocols.
254
255<p>
256Since the RSA patent has expired, there are no restrictions on the use
257of RSA algorithm using software, including OpenBSD.

282
283<h2><a name= "2.1">2.1 - Why does ssh/scp make connections from low-numbered ports.</a></h2>
284<p>
285The OpenSSH client uses low numbered ports for rhosts and rhosts-rsa
286authentication because the server needs to trust the username provided by
287the client. To get around this, you can add the below example to your
288<i>ssh_config</i> or <i>~/.ssh/config</i> file.
289
290
291<blockquote>
292<table border=0 width="800">

315
316<h2><a name= "2.2">2.2 - Why is the ssh client setuid root?</a></h2>
317
318<p>
319In conjunction with the previous question, (<a href="#2.1">2.1</a>)
320OpenSSH needs root authority to be able to bind to low-numbered ports to
321facilitate <i>rhosts authentication</i>.
322A privileged port is also required for rhosts-rsa authentication to older
323SSH releases.
324
325<p>
326Additionally, for both <i>rhosts-rsa authentication</i> (in protocol
327version 1) and <i>hostbased authentication</i> (in protocol version 2)
328the ssh client needs to access the <i>private host key</i> in order to
329authenticate the client machine to the server.
330OpenSSH versions prior to 3.3 required the <code>ssh</code> binary to be
331setuid root to enable this, and you may safely remove it if you don't
332want to use these authentication methods.
333
334<p>
335Starting in OpenSSH 3.3, <code>ssh</code> is not setuid by default. <a
336href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keysign">ssh-keysign</a>,
337is used for access to the private hosts keys, and ssh does not use privileged
338source ports by default. If you wish to use a privileged source port, you must
339manually set the setuid bit on <code>ssh</code>.
340
341<h2><a name= "2.3">2.3 - Why does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?</a></h2>
342
343<p>
344SSH 2.3 and earlier versions contain a flaw in their HMAC implementation.
345Their code was not supplying the full data block output from the digest,
346and instead always provided 128 bits. For longer digests, this caused
347SSH 2.3 to not interoperate with OpenSSH.
348
349<p>
350OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH
351will have this bug fixed. Or you can add the following to
352SSH 2.3 <i>sshd2_config</i>.

365<h2><a name= "2.4">2.4 - Why does OpenSSH print: Dispatch protocol error: type 20</a></h2>
366
367<p>
368Problems in interoperation have been seen because older versions of
369OpenSSH did not support session rekeying. However the commercial SSH 2.3
370tries to negotiate this feature, and you might experience connection
371freezes or see the error message &quot;<b>Dispatch protocol error:
372type 20 </b>&quot;.
373To solve this problem, either upgrade to a recent OpenSSH release or
374disable rekeying by adding the following to your commercial SSH 2.3's
375<i>ssh2_config</i> or <i>sshd2_config</i>.

416<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh-keygen&amp;sektion=1">ssh-keygen(1)</a>
417program contained a bug which caused it to occasionally generate Pubkey
418Authentication (RSA or DSA) keys which had their Most Significant Bit
419(MSB) unset. Such keys were advertised as being full-length, but are
420actually, half the time, smaller than advertised.
421
422<p>
423OpenSSH will print warning messages when it encounters such keys. To rid
424yourself of these message, edit your <i>known_hosts</i> files and replace the
425incorrect key length (usually "1024") with the correct key length
426(usually "1023").

428<h2><a name= "2.7">2.7 - X11 and/or agent forwarding does not work.</a></h2>
429
430<p>
431Check your <i>ssh_config</i> and <i>sshd_config</i>. The default
432configuration files disable authentication agent and X11 forwarding. To
433enable it, put the line below in <i>sshd_config</i>:

458

462>xauth(1)</a> binary. On OpenBSD this is in the <i>xbase</i> file
463set but will probably be different on other platforms. For OpenSSH
464Portable, xauth must be either found at configure time or specified
465via <b>XAuthLocation</b> in sshd_config(5) and ssh_config(5).
466
467<p>
468Note on agent interoperability: There are two different and
469incompatible agent forwarding mechanisms within the SSH2 protocol.
470OpenSSH has always used an extension of the original SSH1 agent
471requests, however some commercial products use a different, non-free
472agent forwarding protocol. This means that agent forwarding cannot
473be used between OpenSSH and those products.

514
515<p>
516sftp and/or scp may fail at connection time if you have shell
517initialization (.profile, .bashrc, .cshrc, etc) which produces output
518for non-interactive sessions. This output confuses the sftp/scp client.

534
535<h2><a name= "2.10">2.10 - Will you add [foo] to scp?</a></h2>
536
537<p>
538Short Answer: no.
539
540<p>
541Long Answer: scp is not standardized. The closest thing it has to a
542specification is "what rcp does". Since the same command is used on both ends
543of the connection, adding features or options risks breaking interoperability with other
544implementations.
545
546<p>
547New features are more likely in sftp, since the protocol is standardized
548(well, a <a href="http://www.ietf.org/html.charters/OLD/secsh-charter.html">
549draft standard</a>), extensible, and the client and server are decoupled.
550
551<h2><a name= "2.11">2.11 - How do I use port forwarding?</a></h2>
552
553<p>
554If the remote server is running sshd(8), it may be possible to
555``tunnel'' certain services via ssh. This may be desirable, for
556example, to encrypt POP or SMTP connections, even though the software
557does not directly support encrypted communications. Tunnelling uses
558port forwarding to create a connection between the client and server.
559The client software must be able to specify a non-standard port to
560connect to for this to work.
561
562<p>
563The idea is that the user connects to the remote host using ssh,
564and specifies which port on the client's machine should be used to
565forward connections to the remote server. After that it is possible
566to start the service which is to be encrypted (e.g. fetchmail, irc)
567on the client machine, specifying the same local port passed to
568ssh, and the connection will be tunnelled through ssh. By default,
569the system running the forward will only accept connections from
570itself.
571
572<p>
573The options most relevant to tunnelling are the -L and -R options,
574which allow the user to forward connections, the -D option, which
575permits dynamic port forwarding, the -g option, which permits other
576hosts to use port forwards, and the -f option, which instructs ssh
577to put itself in the background after authentication. See the <a
578href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1"
579>ssh(1)</a> man page for further details.
580
581<p>
582This is an example of tunnelling an IRC session from client machine
583``127.0.0.1'' (localhost) to remote server ``server.example.com'':
584
585<blockquote>
586<table border=0 width="800">
587 <tr>
588 <td nowrap bgcolor="#EEEEEE">
589<b>ssh -f -L 1234:server.example.com:6667 server.example.com sleep 10<br>
590irc -c '#users' -p 1234 pinky 127.0.0.1</b>
591 </td>
592 </tr>
593</table>
594</blockquote>
595
596<p>
597This tunnels a connection to IRC server server.example.com, joining
598channel ``#users'', using the nickname ``pinky''. The local port used
599in this example is 1234. It does not matter which port is used, as
600long as it's greater than 1023 (remember, only root can open sockets on
601privileged ports) and doesn't conflict with any ports already in use.
602The connection is forwarded to port 6667 on the remote server, since
603that's the standard port for IRC services.
604
605<p>
606The remote command ``sleep 10'' was specified to allow an amount
607of time (10 seconds, in the example) to start the service which is to
608be tunnelled. If no connections are made within the time specified,
609ssh will exit. If more time is required, the sleep(1) value can be
610increased appropriately or, alternatively, the example above could
611be added as a function to the user's shell. See ksh(1) and csh(1)
612for more details about user-defined functions.
613
614<p>
615ssh also has an -N option, convenient for use with port forwarding:
616if -N is specified, it is not necessary to specify a remote command
617(``sleep 10'' in the example above). However, use of this option
618causes ssh to wait around for ever (as opposed to exiting after a
619remote command has completed), and the user must take care to manually
620kill(1) the process afterwards.
621
622<h2><a name= "2.12">2.12 - My ssh connection freezes or drops out after N minutes of inactivity.</a></h2>
623
624<p>
625This is usually the result of a packet filter or NAT device
626timing out your TCP connection due to inactivity. You can enable
627<b>ClientAliveInterval</b> in the server's <i><a
628href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&amp;sektion=5">
629sshd_config</a></i>, or enable <b>ServerAliveInterval</b> in the

631href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh_config&amp;sektion=5">
632ssh_config</a></i> (the latter is available in OpenSSH 3.8 and newer).
633
634<p>
635Enabling either option and setting the interval for less than the time
636it takes to time out your session will ensure that the connection is
637kept "fresh" in the device's connection table.

692</table>
693</blockquote>
694
695<p>
696These are generated because OpenSSH first tries to determine whether a
697user needs authentication to login (e.g. empty password). Unfortunately
698PAM likes to log all authentication events, this one included.
699
700<p>
701If it annoys you too much, set &quot;<b>PermitEmptyPasswords no</b>&quot;
702in <i>sshd_config</i>. This will quiet the error message at the expense
703of disabling logins to accounts with no password set.
704This is the default if you use the supplied <i>sshd_config</i> file.
705
706<h2><a name= "3.2">3.2 - Empty passwords not allowed with PAM authentication.</a></h2>
707
708<p>
709To enable empty passwords with a version of OpenSSH built with PAM you
710must add the flag nullok to the end of the password checking module
711in the <i>/etc/pam.d/sshd</i> file. For example:
712
713<blockquote>
714<table border=0 width="800">

716 <td nowrap bgcolor="#EEEEEE">
717auth required/lib/security/pam_unix.so shadow nodelay nullok
718 </td>
719 </tr>
720</table>
721</blockquote>
722
723<p>
724This must be done in addition to setting &quot;<b>PermitEmptyPasswords
725yes</b>&quot; in the <i>sshd_config</i> file.
726
727<p>
728There is one caveat when using empty passwords with PAM authentication:
729PAM will allow any password when authenticating an account with an empty
730password. This breaks the check that
731<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>
732uses to determine whether an account has no password set and grant

743Large delays (more than 10 seconds) are typically caused by a problem with
744name resolution:
745<ul>
746<li>Some versions of glibc (notably glibc 2.1 shipped with Red Hat 6.1)
747can take a long time to resolve "IPv6 or IPv4" addresses from domain
748names. This can be worked around with by specifying <b>AddressFamily
749inet</b> option in <i>ssh_config</i>.</li>
750
751<li>There may be a DNS lookup problem, either at the client or server.
752You can use the <code>nslookup</code> command to check this on both client
753and server by looking up the other end's name and IP address. In
754addition, on the server look up the name returned by the client's
755IP-name lookup. You can disable most of the server-side lookups by
756setting <b>UseDNS no</b> in <i>sshd_config</i>.</li>
757</ul>
758
759<p>
760Delays less than 10 seconds can have other causes.
761
762<ul>
763
764<li>OpenSSH releases prior to 3.8 had an <i>moduli</i> file with
765moduli that were just smaller than what sshd would look for, and
766as a result, sshd would end up using moduli significantly larger
767than requested, which resulted in a speed penalty. Replacing the
768<i>moduli</i> file will resolve this (note that in most cases this
769file will not be replaced during an upgrade and must be replaced
770manually).</li>
771
772<li>OpenSSH releases prior to 3.8 had a flaw in <code>ssh</code> that
773would cause it to request moduli larger than intended (which when
774combined with the above resulted in significant slowdowns).
775Upgrading the client to 3.8 or higher will resolve this issue.</li>
776
777<li>If either the client or server lack a kernel-based random number
778device (eg Solaris &lt; 9, AIX &lt; 5.2, HP-UX &lt; 11.11) and no
779substitute is available (eg <a href=
780"ftp://ftp.ayamura.org/pub/prngd/">prngd</a>) it's possible that
781one of the programs called by <code>ssh-rand-helper</code> to
782generate entropy is hanging. This can be investigated by running
783it in debug mode:

835The Linux kernel is looking (via modprobe) for protocol family 10 (IPv6).
836Either load the appropriate kernel module, enter the correct alias in

845<h2><a name= "3.5">3.5 - Password authentication doesn't work (eg on Slackware 7.0 or Red Hat 6.x)</a></h2>
846
847<p>
848If the password is correct password the login is still denied, the
849usual cause is that the system is configured to use MD5-type passwords
850but the
851<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=crypt&amp;sektion=3"
852>crypt(3)</a> function used by sshd doesn't understand them.
853
854<p>
855Affected accounts will have password strings in <i>/etc/passwd</i>
856or <i>/etc/shadow</i> that start with <b>$1$</b>.
857If password authentication fails for new accounts or accounts with
858recently changed passwords, but works for old accounts, this is the
859likely culprit.
860
861<p>
862The underlying cause is that some versions of OpenSSL have a crypt(3)
863function that does not understand MD5 passwords, and the link order of
864sshd means that OpenSSL's crypt(3) is used instead of the system's.
865OpensSSH's configure attempts to correct for this but is not always
866successful.
867
868<p>
869There are several possible solutions:
870
871<ul>
872<li>
873<p>
874Enable sshd's built-in support for MD5 passwords at build time.

882 </tr>
883</table>
884</blockquote>
885
886This is safe even if you have both types of encryption as sshd will
887select the correct algorithm for each account automatically.
888
889<li>
890<p>
891If your system has a separate libcrypt library (eg Slackware 7) then you
892can manually add -lcrypt to the LIBS list so it's used instead of
893OpenSSL's:
894
895<blockquote>
896<table border=0 width="800">

902</table>
903</blockquote>
904
905<li>
906<p>
907If your platforms supports PAM, you may configure sshd to use it
908(see <a href= "#3.15" >section 3.15</a>). This will mean that sshd will
909not verify passwords itself but will defer to the configured PAM modules.

912<h2><a name= "3.6">3.6 - Configure or sshd(8) complain about lack of RSA or DSA support</a></h2>

923must be in the default PATH on both the client and the server. You may
924need to use the <b>--with-default-path</b> option to specify a custom
925path to search on the server. This option replaces the default path,
926so you need to specify all the current directories on your path as well
927as where you have installed scp. For example:
928
929<blockquote>

937</blockquote>
938
939<p>
940Note that configuration by the server's admin will take precedence over the
941setting of <b>--with-default-path</b>. This includes resetting PATH in
942<i>/etc/profile</i>, PATH in <i>/etc/environment</i> on AIX, or (for 3.7p1 and
943above) setting PATH or SUPATH in <i>/etc/default/login</i> on Solaris or

946<h2><a name= "3.8">3.8 - Unable to read passphrase</a></h2>

1048In general, X11 clients using X11 R6 should work with the default
1049setting. Some vendors, including HP, ship X11 clients with R6
1050and R5 libs, so some clients will work, and others will not work.
1051This is true for HP-UX 11.X.<p>

1.TH GNOME-SSH-ASKPASS 1
2.SH NAME
3gnome\-ssh\-askpass \- prompts a user for a passphrase using GNOME
4.SH SYNOPSIS
5.B gnome\-ssh\-askpass
6.SH DESCRIPTION
7.B gnome\-ssh\-askpass
8is a GNOME-based passphrase dialog for use with OpenSSH.
9It is intended to be called by the
10.BR ssh\-add (1)
11program and not invoked directly.
12It allows
13.BR ssh\-add (1)
14to obtain a passphrase from a user, even if not connected to a terminal
15(assuming that an X display is available).
16This happens automatically in the case where
17.B ssh\-add
18is invoked from one's
19.B ~/.xsession
20or as one of the GNOME startup programs, for example.
21.PP
22In order to be called automatically by
23.BR ssh\-add ,
24.B gnome\-ssh\-askpass
25should be installed as
26.IR /usr/bin/ssh\-askpass .
27.SH "ENVIRONMENT VARIABLES"
28The following environment variables are recognized:
29.TP
30.I GNOME_SSH_ASKPASS_GRAB_SERVER
31Causes
32.B gnome\-ssh\-askpass
33to grab the X server before asking for a passphrase.
34.TP
35.I GNOME_SSH_ASKPASS_GRAB_POINTER
36Causes
37.B gnome\-ssh\-askpass
38to grab the mouse pointer using
39.IR gdk_pointer_grab ()
40before asking for a passphrase.
41.PP
42Regardless of whether either of these environment variables is set,
43.B gnome\-ssh\-askpass
44will grab the keyboard using
45.IR gdk_keyboard_grab ().
46.SH AUTHOR
47This manual page was written by Colin Watson <cjwatson@debian.org>
48for the Debian system (but may be used by others).
49It was based on that for

4Subject: GSSAPI key exchange support
5
6This patch has been rejected upstream: "None of the OpenSSH developers are
7in favour of adding this, and this situation has not changed for several
8years. This is not a slight on Simon's patch, which is of fine quality, but
9just that a) we don't trust GSSAPI implementations that much and b) we don't
10like adding new KEX since they are pre-auth attack surface. This one is
11particularly scary, since it requires hooks out to typically root-owned
12system resources."
13
14However, quite a lot of people rely on this in Debian, and it's better to
15have it merged into the main openssh package rather than having separate
16-krb5 packages (as we used to have). It seems to have a generally good
17security history.

6Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
7in previous versions of Debian's OpenSSH package but since superseded by
8ServerAliveInterval. (We're probably stuck with this bit for
9compatibility.)
10
11In batch mode, default ServerAliveInterval to five minutes.

13Adjust documentation to match and to give some more advice on use of
14keepalives.

4Subject: Include the Debian version in our identification
5
6This makes it easier to audit networks for versions patched against security
7vulnerabilities. It has little detrimental effect, as attackers will
8generally just try attacks rather than bothering to scan for
9vulnerable-looking version strings. (However, see debian-banner.patch.)

4Subject: Reduce severity of "Killed by signal %d"
5
6This produces irritating messages when using ProxyCommand or other programs
7that use ssh under the covers (e.g. Subversion). These messages are more
8normally printed by the calling program, such as the shell.
9
10According to the upstream bug, the right way to avoid this is to use the -q
11option, so we may drop this patch after further investigation into whether
12any software in Debian is still relying on it.

4Subject: Handle SELinux authorisation roles
5
6Rejected upstream due to discomfort with magic usernames; a better approach
7will need an SSH protocol change. In the meantime, this came from Debian's
8SELinux maintainer, so we'll keep it until we have something better.

4Subject: ssh(1): Refer to ssh-argv0(1)
5
6Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks
7to ssh with the name of the host you want to connect to. Debian ships an
8ssh-argv0 script restoring this feature; this patch refers to its manual
9page from ssh(1).

5
6These options were used as part of Debian's response to CVE-2008-0166.
7Nearly six years later, we no longer need to continue carrying the bulk
8of that patch, but we do need to avoid failing when the associated
9configuration options are still present.

4Subject: "LogLevel SILENT" compatibility
5
6"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
7match the behaviour of non-free SSH, in which -q does not suppress fatal
8errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody
9complained, so we've dropped most of it. The parts that remain are basic
10configuration file compatibility, and an adjustment to "Pseudo-terminal will
11not be allocated ..." which should be split out into a separate patch.

4Subject: Allow harmless group-writability
5
6Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be
7group-writable, provided that the group in question contains only the file's
8owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding
9about the contents of gr->gr_mem). Given that per-user groups and umask 002
10are the default setup in Debian (for good reasons - this makes operating in
11setgid directories with other groups much easier), we need to permit this by
12default.

42.Nm
43replaces the old ssh command-name as hostname handling.
44If you link to this script with a hostname then executing the link is
45equivalent to having executed ssh with that hostname as an argument.
46All other arguments are passed to ssh and will be processed normally.

1This package contains a Gnome based implementation of ssh-askpass
2written by Damien Miller.
3
4It is split out from the main package to isolate the dependency on the
5Gnome and X11 libraries.
6
7It was packaged for Debian by Philip Hands <phil@hands.com>.

1ssh-krb5 (1:4.3p2-7) unstable; urgency=low
2
3 The normal openssh-server and openssh-client packages in Debian now
4 include full GSSAPI support, including key exchange. This package is
5 now only a transitional package that depends on openssh-server and
6 openssh-client and configures openssh-server for GSSAPI authentication
7 if it wasn't already.
8
9 You can now simply install openssh-server and openssh-client directly
10 and remove this package. Just make sure that /etc/ssh/sshd_config
11 contains:
12
13 GSSAPIAuthentication yes
14 GSSAPIKeyExchange yes
15
16 if you want to support GSSAPI authentication to your ssh server.
