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
52X11 Forwarding
53--------------
54
55ssh's default for ForwardX11 has been changed to ``no'' because it has
56been pointed out that logging into remote systems administered by
57untrusted people is likely to open you up to X11 attacks, so you
58should have to actively decide that you trust the remote machine's
59root, before enabling X11. I strongly recommend that you do this on a
60machine-by-machine basis, rather than just enabling it in the default
61host settings.
62
63In order for X11 forwarding to work, you need to install xauth on the
64server. In Debian this is in the xbase-clients package.
65
66As of OpenSSH 3.1, the remote $DISPLAY uses localhost by default to reduce
67the security risks of X11 forwarding. Look up X11UseLocalhost in
68sshd_config(8) if this is a problem.
69
70OpenSSH 3.8 invented ForwardX11Trusted, which when set to no causes the
71ssh client to create an untrusted X cookie so that attacks on the
72forwarded X11 connection can't become attacks on X clients on the remote
73machine. However, this has some problems in implementation - notably a
74very short timeout of the untrusted cookie - breaks large numbers of
75existing setups, and generally seems immature. The Debian package
76therefore sets the default for this option to "yes" (in ssh itself,
77rather than in ssh_config).
78
79Fallback to RSH
80---------------
81
82The default for this setting has been changed from Yes to No, for
83security reasons, and to stop the delay attempting to rsh to machines
84that don't offer the service. Simply switch it back on in either
85/etc/ssh/ssh_config or ~/.ssh/config for those machines that you need
86it for.
87
88Setgid ssh-agent and environment variables
89------------------------------------------
90
91As of version 1:3.5p1-1, ssh-agent is installed setgid to prevent ptrace()
92attacks retrieving private key material. This has the side-effect of causing
93glibc to remove certain environment variables which might have security
94implications for set-id programs, including LD_PRELOAD, LD_LIBRARY_PATH, and
95TMPDIR.
96
97If you need to set any of these environment variables, you will need to do
98so in the program exec()ed by ssh-agent. This may involve creating a small
99wrapper script.
100
101Symlink Hostname invocation
102---------------------------
103
104This version of ssh no longer includes support for invoking ssh with the
105hostname as the name of the file run. People wanting this support should
106use the ssh-argv0 script.
107
108=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
109
110OTHER ISSUES
111============
112
113/usr/bin/ssh not SUID
114---------------------
115
116Due to Debian bug #164325, RhostsRSAAuthentication can only be used if ssh
117is SUID. Until this is fixed, if that is a problem, use:
118
119 dpkg-statoverride
120
121or if that's also missing, use this:
122
123 chown root.root /usr/bin/ssh
124 chmod 04755 /usr/bin/ssh
125
126Authorization Forwarding
127------------------------
128
129Similarly, root on a remote server could make use of your ssh-agent
130(while you're logged into their machine) to obtain access to machines
131which trust your keys. This feature is therefore disabled by default.
132You should only re-enable it for those hosts (in your ~/.ssh/config or
133/etc/ssh/ssh_config) where you are confident that the remote machine
134is not a threat.
135
136Problems logging in with RSA authentication
137-------------------------------------------
138
139If you have trouble logging in with RSA authentication then the
140problem is probably caused by the fact that you have your home
141directory writable by group, as well as user (this is the default on
142Debian systems).
143
144Depending upon other settings on your system (i.e. other users being
145in your group) this could open a security hole, so you will need to
146make your home directory writable only by yourself. Run this command,
147as yourself:
148
149 chmod g-w ~/
150
151to remove group write permissions. If you use ssh-copy-id to install your
152keys, it does this for you.
153
154-L option of ssh nonfree
155------------------------
156
157non-free ssh supported the usage of the option -L to use a non privileged
158port for scp. This option will not be supported by scp from openssh.
159
160Please use instead scp -o "UsePrivilegedPort=no" as documented in the
161manpage to scp itself.
162
163Problem logging in because of TCP-Wrappers
164------------------------------------------
165
166ssh is compiled with support for tcp-wrappers. So if you can no longer
167log into your system, please check that /etc/hosts.allow and /etc/hosts.deny
168are configured so that ssh is not blocked.
169
170Kerberos support
171----------------
172
173ssh is now compiled with Kerberos support. Unfortunately, privilege
174separation is incompatible with Kerberos support for SSH protocol 1 and
175parts of the support for protocol 2; you may need to run kinit after logging
176in.
177
178Interoperability between scp and the ssh.com SSH server
179-------------------------------------------------------
180
181In version 2 and greater of the commercial SSH server produced by SSH
182Communications Security, scp was changed to use SFTP (SSH2's file transfer
183protocol) instead of the traditional rcp-over-ssh, thereby breaking
184compatibility. The OpenSSH developers regard this as a bug in the ssh.com
185server, and do not currently intend to change OpenSSH's scp to match.
186
187Workarounds for this problem are to install scp1 on the server (scp2 will
188fall back to it), to use sftp, or to use some other transfer mechanism such
189as rsync-over-ssh or tar-over-ssh.
190
191Running sshd from inittab
192-------------------------
193
194Some people find it useful to run the sshd server from inittab, to make sure
195that it always stays running. To do this, stop sshd ('/etc/init.d/ssh
196stop'), add the following line to /etc/inittab, and run 'telinit q':
197
198 ss:2345:respawn:/usr/sbin/sshd -D
199
200If you do this, note that you will need to stop sshd being started in the
201normal way ('update-rc.d ssh disable') and that you will need to restart
202this sshd manually on upgrades.
203
204Per-connection sshd instances with systemd
205------------------------------------------
206
207If you want to reconfigure systemd to listen on port 22 itself and launch an
208instance of sshd for each connection (inetd-style socket activation), then
209you can run:
210
211 systemctl stop ssh.service
212 systemctl start ssh.socket
213
214To make this permanent:
215
216 systemctl disable ssh.service
217 systemctl enable ssh.socket
218
219This may be appropriate in environments where minimal footprint is critical
220(e.g. cloud guests). Be aware that this bypasses MaxStartups, and systemd's
221MaxConnections cannot quite replace this as it cannot distinguish between
222authenticated and unauthenticated connections; see
223https://bugzilla.redhat.com/show_bug.cgi?id=963268 for more discussion.

25 * Bump guard version for sysvinit->systemd transition to 1:6.5p1-3; we may
26 have got it wrong before, and it's fairly harmless to repeat it.
27 * Remove tests for whether /dev/null is a character device from the
28 Upstart job and the systemd service files; it's there to avoid a
29 confusing failure mode in daemon(), but with modern init systems we use
30 the -D option to suppress daemonisation anyway.
31 * Refer to /usr/share/common-licenses/GPL-2 in debian/copyright (for the
32 Debian patch) rather than plain GPL.
33 * Drop some very old Conflicts and Replaces (ssh (<< 1:3.8.1p1-9),
34 rsh-client (<< 0.16.1-1), ssh-krb5 (<< 1:4.3p2-7), ssh-nonfree (<< 2),
35 and openssh-client (<< 1:3.8.1p1-11)). These all relate to pre-etch
36 versions, for which we no longer have maintainer script code, and per
37 policy they would have to become Breaks nowadays anyway.
38 * Policy version 3.9.5.
39 * Drop unnecessary -1 in zlib1g Build-Depends version.
40 * Tweak dh_systemd_enable invocations to avoid lots of error noise.

54
55 * New upstream release (http://www.openssh.com/txt/release-6.5,
56 LP: #1275068):
57 - ssh(1): Add support for client-side hostname canonicalisation using a
58 set of DNS suffixes and rules in ssh_config(5). This allows
59 unqualified names to be canonicalised to fully-qualified domain names
60 to eliminate ambiguity when looking up keys in known_hosts or checking
61 host certificate names (closes: #115286).
62 * Switch to git; adjust Vcs-* fields.
63 * Convert to git-dpm, and drop source package documentation associated
64 with the old bzr/quilt patch handling workflow.
65 * Drop ssh-vulnkey and the associated ssh/ssh-add/sshd integration code,
66 leaving only basic configuration file compatibility, since it has been
67 nearly six years since the original vulnerability and this code is not
68 likely to be of much value any more (closes: #481853, #570651). See
69 https://lists.debian.org/debian-devel/2013/09/msg00240.html for my full
70 reasoning.
71 * Add OpenPGP signature checking configuration to watch file (thanks,
72 Daniel Kahn Gillmor; closes: #732441).
73 * Add the pam_keyinit session module, to create a new session keyring on
74 login (closes: #734816).
75 * Incorporate default path changes from shadow 1:4.0.18.1-8, removing
76 /usr/bin/X11 (closes: #644521).
77 * Generate ED25519 host keys on fresh installations. Upgraders who wish
78 to add such host keys should manually add 'HostKey
79 /etc/ssh/ssh_host_ed25519_key' to /etc/ssh/sshd_config and run
80 'ssh-keygen -q -f /etc/ssh/ssh_host_ed25519_key -N "" -t ed25519'.
81 * Drop long-obsolete "SSH now uses protocol 2 by default" section from
82 README.Debian.
83 * Add systemd support (thanks, Sven Joachim; closes: #676830).

99 + sftp(1): add support for resuming partial downloads using the
100 "reget" command and on the sftp commandline or on the "get"
101 commandline using the "-a" (append) option (closes: #158590).
102 + ssh(1): add an "IgnoreUnknown" configuration option to selectively
103 suppress errors arising from unknown configuration directives
104 (closes: #436052).
105 + sftp(1): update progressmeter when data is acknowledged, not when
106 it's sent (partially addresses #708372).
107 + ssh(1): do not fatally exit when attempting to cleanup multiplexing-
108 created channels that are incompletely opened (closes: #651357).
109 - 6.4/6.4p1 (http://www.openssh.com/txt/release-6.4):
110 + CVE-2013-4548: sshd(8): fix a memory corruption problem triggered
111 during rekeying when an AES-GCM cipher is selected (closes:
112 #729029). Full details of the vulnerability are available at:
113 http://www.openssh.com/txt/gcmrekey.adv
114 * When running under Upstart, only consider the daemon started once it is
115 ready to accept connections (by raising SIGSTOP at that point and using
116 "expect stop").

154 * If the running init daemon is Upstart, then, on the first upgrade to

156 manually stop it so that it can be restarted under upstart. We do this
157 near the end of the postinst, so it shouldn't result in any appreciable
158 extra window where sshd is not running during upgrade.

163
164 * Change start condition of Upstart job to be just the standard "runlevel
165 [2345]", rather than "filesystem or runlevel [2345]"; the latter makes
166 it unreasonably difficult to ensure that urandom starts before ssh, and
167 is not really necessary since one of static-network-up and failsafe-boot
168 is guaranteed to happen and will trigger entry to the default runlevel,
169 and we don't care about ssh starting before the network (LP: #1098299).
170 * Drop conffile handling for direct upgrades from pre-split ssh package;
171 this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
172 truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
173 now four Debian releases ago, we can afford to drop this and simplify
174 the packaging.
175 * Remove ssh/use_old_init_script, which was a workaround for a very old
176 bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
177 they aren't going to be convinced now (closes: #214182).
178 * Remove support for upgrading directly from ssh-nonfree.
179 * Remove lots of maintainer script support for direct upgrades from
180 pre-etch (three releases before current stable).
181 * Add #DEBHELPER# tokens to openssh-client.postinst and
182 openssh-server.postinst.
183 * Replace old manual conffile handling code with dpkg-maintscript-helper,
184 via dh_installdeb.
185 * Switch to new unified layout for Upstart jobs as documented in
186 https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
187 checks for a running Upstart, and we now let dh_installinit handle most
188 of the heavy lifting in maintainer scripts. Ubuntu users should be
189 essentially unaffected except that sshd may no longer start
190 automatically in chroots if the running Upstart predates 0.9.0; but the
191 main goal is simply not to break when openssh-server is installed in a
192 chroot.
193 * Remove the check for vulnerable host keys; this was first added five
194 years ago, and everyone should have upgraded through a version that
195 applied these checks by now. The ssh-vulnkey tool and the blacklisting
196 support in sshd are still here, at least for the moment.
197 * This removes the last of our uses of debconf (closes: #221531).
198 * Use the pam_loginuid session module (thanks, Laurent Bigonville; closes:
199 #677440, LP: #1067779).
200 * Bracket our session stack with calls to pam_selinux close/open (thanks,
201 Laurent Bigonville; closes: #679458).
202 * Fix dh_builddeb invocation so that we really use xz compression for
203 binary packages, as intended since 1:6.1p1-2.

470 * New upstream release (http://www.openssh.org/txt/release-5.7):
471 - Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
472 and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
473 offer better performance than plain DH and DSA at the same equivalent
474 symmetric key length, as well as much shorter keys.
475 - sftp(1)/sftp-server(8): add a protocol extension to support a hard
476 link operation. It is available through the "ln" command in the
477 client. The old "ln" behaviour of creating a symlink is available
478 using its "-s" option or through the preexisting "symlink" command.
479 - scp(1): Add a new -3 option to scp: Copies between two remote hosts
480 are transferred through the local host (closes: #508613).
481 - ssh(1): "atomically" create the listening mux socket by binding it on
482 a temporary name and then linking it into position after listen() has
483 succeeded. This allows the mux clients to determine that the server
484 socket is either ready or stale without races (closes: #454784).
485 Stale server sockets are now automatically removed (closes: #523250).
486 - ssh(1): install a SIGCHLD handler to reap expired child process
487 (closes: #594687).
488 - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
489 temporary directories (closes: #357469, although only if you arrange
490 for ssh-agent to actually see $TMPDIR since the setgid bit will cause
491 it to be stripped off).
492 * Update to current GSSAPI patch from
493 http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
494 - Add GSSAPIServerIdentity option.
495 * Generate ECDSA host keys on fresh installations. Upgraders who wish to
496 add such host keys should manually add 'HostKey
497 /etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
498 -q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
499 * Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
500 * Backport SELinux build fix from CVS.
501 * Rearrange selinux-role.patch so that it links properly given this
502 SELinux build fix.

619
620 * New upstream release (LP: #535029).
621 - After a transition period of about 10 years, this release disables SSH
622 protocol 1 by default. Clients and servers that need to use the
623 legacy protocol must explicitly enable it in ssh_config / sshd_config
624 or on the command-line.
625 - Remove the libsectok/OpenSC-based smartcard code and add support for
626 PKCS#11 tokens. This support is enabled by default in the Debian
627 packaging, since it now doesn't involve additional library
628 dependencies (closes: #231472, LP: #16918).
629 - Add support for certificate authentication of users and hosts using a
630 new, minimal OpenSSH certificate format (closes: #482806).
631 - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
632 - Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
633 package, this overlaps with the key blacklisting facility added in
634 openssh 1:4.7p1-9, but with different file formats and slightly
635 different scopes; for the moment, I've roughly merged the two.)
636 - Various multiplexing improvements, including support for requesting
637 port-forwardings via the multiplex protocol (closes: #360151).
638 - Allow setting an explicit umask on the sftp-server(8) commandline to
639 override whatever default the user has (closes: #496843).
640 - Many sftp client improvements, including tab-completion, more options,
641 and recursive transfer support for get/put (LP: #33378). The old
642 mget/mput commands never worked properly and have been removed
643 (closes: #270399, #428082).
644 - Do not prompt for a passphrase if we fail to open a keyfile, and log
645 the reason why the open failed to debug (closes: #431538).
646 - Prevent sftp from crashing when given a "-" without a command. Also,
647 allow whitespace to follow a "-" (closes: #531561).
648
649 * Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
650 patches apply with offsets.
651 * Include debian/ssh-askpass-gnome.png in the Debian tarball now that
652 we're using a source format that permits this, rather than messing
653 around with uudecode.
654 * Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
655 3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
656 mechanism was removed due to a serious security hole, and since these
657 versions of ssh-krb5 are no longer security-supported by Debian I don't
658 think there's any point keeping client compatibility for them.
659 * Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
660 * Hardcode the location of xauth to /usr/bin/xauth rather than
661 /usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
662 xauth no longer depends on x11-common, so we're no longer guaranteed to
663 have the /usr/bin/X11 symlink available. I was taking advantage of the
664 /usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
665 enough in the past now that it's probably safe to just use /usr/bin.
666 * Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
667 itself non-OOM-killable, and doesn't require configuration to avoid log
668 spam in virtualisation containers (closes: #555625).
669 * Drop Debian-specific removal of OpenSSL version check. Upstream ignores
670 the two patchlevel nybbles now, which is sufficient to address the
671 original reason this change was introduced, and it appears that any
672 change in the major/minor/fix nybbles would involve a new libssl package
673 name. (We'd still lose if the status nybble were ever changed, but that
674 would mean somebody had packaged a development/beta version rather than
675 a proper release, which doesn't appear to be normal practice.)
676 * Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
677 introduced to match the behaviour of non-free SSH, in which -q does not
678 suppress fatal errors, but matching the behaviour of OpenSSH upstream is
679 much more important nowadays. We no longer document that -q does not
680 suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
681 "LogLevel QUIET" in sshd_config on upgrade.
682 * Policy version 3.8.4:
683 - Add a Homepage field.

738 * Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file
739 descriptor passing when running on Linux 2.0. The previous stable

754 - Change the default cipher order to prefer the AES CTR modes and the
755 revised "arcfour256" mode to CBC mode ciphers that are susceptible to
756 CPNI-957037 "Plaintext Recovery Attack Against SSH".
757 - Add countermeasures to mitigate CPNI-957037-style attacks against the
758 SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
759 packet length or Message Authentication Code, ssh/sshd will continue
760 reading up to the maximum supported packet length rather than
761 immediately terminating the connection. This eliminates most of the
762 known differences in behaviour that leaked information about the
763 plaintext of injected data which formed the basis of this attack
764 (closes: #506115, LP: #379329).
765 - ForceCommand directive now accepts commandline arguments for the

769 - Make ssh(1) send the correct channel number for
770 SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
771 avoid triggering 'Non-public channel' error messages on sshd(8) in
772 openssh-5.1.
773 - Avoid printing 'Non-public channel' warnings in sshd(8), since the
774 ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a

860 - packet_disconnect() on padding error, too. Should reduce the success
861 probability for the CPNI-957037 Plaintext Recovery Attack to 2^-18.
862 * Check that /var/run/sshd.pid exists and that the process ID listed there
863 corresponds to sshd before running '/etc/init.d/ssh reload' from if-up
864 script; SIGHUP is racy if called at boot before sshd has a chance to
865 install its signal handler, but fortunately the pid file is written
866 after that which lets us avoid the race (closes: #502444).
867 * While the above is a valuable sanity-check, it turns out that it doesn't
868 really fix the bug (thanks to Kevin Price for testing), so for the
869 meantime we'll just use '/etc/init.d/ssh restart', even though it is

909
910 * New upstream release (closes: #474301). Important changes not previously
911 backported to 4.7p1:
912 - 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
913 + Added chroot(2) support for sshd(8), controlled by a new option
914 "ChrootDirectory" (closes: #139047, LP: #24777).
915 + Linked sftp-server(8) into sshd(8). The internal sftp server is used
916 when the command "internal-sftp" is specified in a Subsystem or
917 ForceCommand declaration. When used with ChrootDirectory, the
918 internal sftp server requires no special configuration of files
919 inside the chroot environment.
920 + Added a protocol extension method "posix-rename@openssh.com" for
921 sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
922 prefers this if available (closes: #308561).
923 + Removed the fixed limit of 100 file handles in sftp-server(8).
924 + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
925 keys when in inetd mode and protocol 2 connections are negotiated.
926 This speeds up protocol 2 connections to inetd-mode servers that
927 also allow Protocol 1.
928 + Accept the PermitRootLogin directive in a sshd_config(5) Match
929 block. Allows for, e.g. permitting root only from the local network.
930 + Reworked sftp(1) argument splitting and escaping to be more
931 internally consistent (i.e. between sftp commands) and more
932 consistent with sh(1). Please note that this will change the
933 interpretation of some quoted strings, especially those with
934 embedded backslash escape sequences.
935 + Support "Banner=none" in sshd_config(5) to disable sending of a
936 pre-login banner (e.g. in a Match block).
937 + ssh(1) ProxyCommands are now executed with $SHELL rather than
938 /bin/sh.
939 + ssh(1)'s ConnectTimeout option is now applied to both the TCP
940 connection and the SSH banner exchange (previously it just covered
941 the TCP connection). This allows callers of ssh(1) to better detect
942 and deal with stuck servers that accept a TCP connection but don't
943 progress the protocol, and also makes ConnectTimeout useful for
944 connections via a ProxyCommand.
945 + scp(1) incorrectly reported "stalled" on slow copies (closes:
946 #140828).
947 + scp(1) date underflow for timestamps before epoch.
948 + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
949 instead of the current standard RRSIG.
950 + Correctly drain ACKs when a sftp(1) upload write fails midway,
951 avoids a fatal() exit from what should be a recoverable condition.
952 + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
953 hostname") to not include any IP address in the data to be hashed.
954 + Make ssh(1) skip listening on the IPv6 wildcard address when a
955 binding address of 0.0.0.0 is used against an old SSH server that
956 does not support the RFC4254 syntax for wildcard bind addresses.
957 + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
958 already done for X11/TCP forwarding sockets (closes: #439661).
959 + Fix FD leak that could hang a ssh(1) connection multiplexing master.
960 + Make ssh(1) -q option documentation consistent with reality.
961 + Fixed sshd(8) PAM support not calling pam_session_close(), or
962 failing to call it with root privileges (closes: #372680).
963 + Fix activation of OpenSSL engine support when requested in configure
964 (LP: #119295).
965 + Cache SELinux status earlier so we know if it's enabled after a
966 chroot (LP: #237557).
967 - 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
968 + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
969 and ssh-keygen(1). Visual fingerprint display is controlled by a new
970 ssh_config(5) option "VisualHostKey". The intent is to render SSH
971 host keys in a visual form that is amenable to easy recall and
972 rejection of changed host keys.
973 + sshd_config(5) now supports CIDR address/masklen matching in "Match
974 address" blocks, with a fallback to classic wildcard matching.
975 + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
976 from="..." restrictions, also with a fallback to classic wildcard
977 matching.
978 + Added an extended test mode (-T) to sshd(8) to request that it write
979 its effective configuration to stdout and exit. Extended test mode
980 also supports the specification of connection parameters (username,
981 source address and hostname) to test the application of
982 sshd_config(5) Match rules.
983 + ssh(1) now prints the number of bytes transferred and the overall
984 connection throughput for SSH protocol 2 sessions when in verbose
985 mode (previously these statistics were displayed for protocol 1
986 connections only).
987 + sftp-server(8) now supports extension methods statvfs@openssh.com
988 and fstatvfs@openssh.com that implement statvfs(2)-like operations.
989 + sftp(1) now has a "df" command to the sftp client that uses the
990 statvfs@openssh.com to produce a df(1)-like display of filesystem
991 space and inode utilisation (requires statvfs@openssh.com support on
992 the server).
993 + Added a MaxSessions option to sshd_config(5) to allow control of the
994 number of multiplexed sessions supported over a single TCP
995 connection. This allows increasing the number of allowed sessions
996 above the previous default of 10, disabling connection multiplexing
997 (MaxSessions=1) or disallowing login/shell/subsystem sessions
998 entirely (MaxSessions=0).
999 + Added a no-more-sessions@openssh.com global request extension that
1000 is sent from ssh(1) to sshd(8) when the client knows that it will
1001 never request another session (i.e. when session multiplexing is
1002 disabled). This allows a server to disallow further session requests
1003 and terminate the session in cases where the client has been
1004 hijacked.
1005 + ssh-keygen(1) now supports the use of the -l option in combination
1006 with -F to search for a host in ~/.ssh/known_hosts and display its
1007 fingerprint.
1008 + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
1009 "rsa1" (LP: #129794).
1010 + Added an AllowAgentForwarding option to sshd_config(8) to control
1011 whether authentication agent forwarding is permitted. Note that this
1012 is a loose control, as a client may install their own unofficial
1013 forwarder.
1014 + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
1015 receiving network data, resulting in a ~10% speedup.
1016 + ssh(1) and sshd(8) will now try additional addresses when connecting
1017 to a port forward destination whose DNS name resolves to more than
1018 one address. The previous behaviour was to try the only first
1019 address and give up if that failed.
1020 + ssh(1) and sshd(8) now support signalling that channels are
1021 half-closed for writing, through a channel protocol extension
1022 notification "eow@openssh.com". This allows propagation of closed
1023 file descriptors, so that commands such as "ssh -2 localhost od
1024 /bin/ls | true" do not send unnecessary data over the wire.
1025 + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
1026 from 768 to 1024 bits.
1027 + When ssh(1) has been requested to fork after authentication ("ssh
1028 -f") with ExitOnForwardFailure enabled, delay the fork until after
1029 replies for any -R forwards have been seen. Allows for robust
1030 detection of -R forward failure when using -f.
1031 + "Match group" blocks in sshd_config(5) now support negation of
1032 groups. E.g. "Match group staff,!guests".
1033 + sftp(1) and sftp-server(8) now allow chmod-like operations to set
1034 set[ug]id/sticky bits.
1035 + The MaxAuthTries option is now permitted in sshd_config(5) match
1036 blocks.
1037 + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
1038 that are available to a primary connection.
1039 + ssh(1) connection multiplexing will now fall back to creating a new
1040 connection in most error cases (closes: #352830).
1041 + Make ssh(1) deal more gracefully with channel requests that fail.
1042 Previously it would optimistically assume that requests would always
1043 succeed, which could cause hangs if they did not (e.g. when the
1044 server runs out of file descriptors).
1045 + ssh(1) now reports multiplexing errors via the multiplex slave's
1046 stderr where possible (subject to LogLevel in the mux master).
1047 + Fixed an UMAC alignment problem that manifested on Itanium
1048 platforms.
1049 * Remove our local version of moduli(5) now that there's one upstream.
1050 * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
1051 * Add lintian overrides for empty /usr/share/doc/openssh-client
1052 directories in openssh-server and ssh (necessary due to being symlink
1053 targets).
1054 * Merge from Ubuntu:
1055 - Add 'status' action to openssh-server init script, requiring lsb-base
1056 (>= 3.2-13) (thanks, Dustin Kirkland).
1057 * debconf template translations:

1230 * Patch from Red Hat / Fedora:
1231 - CVE-2008-1483: Don't use X11 forwarding port which can't be bound on
1232 all address families, preventing hijacking of X11 forwarding by
1233 unprivileged users when both IPv4 and IPv6 are configured (closes:
1234 #463011).

1236 openssh-server.preinst.

1238 - Update Finnish (thanks, Esko Arajärvi; closes: #468563).

1290 * New upstream release (closes: #453367).
1291 - CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
1292 creation of an untrusted cookie fails; found and fixed by Jan Pechanec
1293 (closes: #444738).
1294 - sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
1295 installations are unchanged.
1296 - The SSH channel window size has been increased, and both ssh(1)
1297 sshd(8) now send window updates more aggressively. These improves
1298 performance on high-BDP (Bandwidth Delay Product) networks.
1299 - ssh(1) and sshd(8) now preserve MAC contexts between packets, which
1300 saves 2 hash calls per packet and results in 12-16% speedup for
1301 arcfour256/hmac-md5.
1302 - A new MAC algorithm has been added, UMAC-64 (RFC4418) as
1303 "umac-64@openssh.com". UMAC-64 has been measured to be approximately
1304 20% faster than HMAC-MD5.
1305 - Failure to establish a ssh(1) TunnelForward is now treated as a fatal
1306 error when the ExitOnForwardFailure option is set.
1307 - ssh(1) returns a sensible exit status if the control master goes away
1308 without passing the full exit status.
1309 - When using a ProxyCommand in ssh(1), set the outgoing hostname with
1310 gethostname(2), allowing hostbased authentication to work.
1311 - Make scp(1) skip FIFOs rather than hanging (closes: #246774).
1312 - Encode non-printing characters in scp(1) filenames. These could cause
1313 copies to be aborted with a "protocol error".
1314 - Handle SIGINT in sshd(8) privilege separation child process to ensure
1315 that wtmp and lastlog records are correctly updated.
1316 - Report GSSAPI mechanism in errors, for libraries that support multiple
1317 mechanisms.
1318 - Improve documentation for ssh-add(1)'s -d option.
1319 - Rearrange and tidy GSSAPI code, removing server-only code being linked
1320 into the client.
1321 - Delay execution of ssh(1)'s LocalCommand until after all forwardings
1322 have been established.
1323 - In scp(1), do not truncate non-regular files.
1324 - Improve exit message from ControlMaster clients.
1325 - Prevent sftp-server(8) from reading until it runs out of buffer space,
1326 whereupon it would exit with a fatal error (closes: #365541).
1327 - pam_end() was not being called if authentication failed
1328 (closes: #405041).
1329 - Manual page datestamps updated (closes: #433181).
1330 * Install the OpenSSH FAQ in /usr/share/doc/openssh-client.
1331 - Includes documentation on copying files with colons using scp
1332 (closes: #303453).

1336 * Refactor debian/rules configure and make invocations to make development
1337 easier.

1339 * Update moduli(5) to revision 1.11 from OpenBSD CVS.
1340 * Document the non-default options we set as standard in ssh_config(5) and

1440
1441 * New upstream release (closes: #395507, #397961, #420035). Important
1442 changes not previously backported to 4.3p2:
1443 - 4.4/4.4p1 (http://www.openssh.org/txt/release-4.4):
1444 + On portable OpenSSH, fix a GSSAPI authentication abort that could be
1445 used to determine the validity of usernames on some platforms.
1446 + Implemented conditional configuration in sshd_config(5) using the
1447 "Match" directive. This allows some configuration options to be
1448 selectively overridden if specific criteria (based on user, group,
1449 hostname and/or address) are met. So far a useful subset of
1450 post-authentication options are supported and more are expected to
1451 be added in future releases.
1452 + Add support for Diffie-Hellman group exchange key agreement with a
1453 final hash of SHA256.
1454 + Added a "ForceCommand" directive to sshd_config(5). Similar to the
1455 command="..." option accepted in ~/.ssh/authorized_keys, this forces
1456 the execution of the specified command regardless of what the user
1457 requested. This is very useful in conjunction with the new "Match"
1458 option.
1459 + Add a "PermitOpen" directive to sshd_config(5). This mirrors the
1460 permitopen="..." authorized_keys option, allowing fine-grained
1461 control over the port-forwardings that a user is allowed to
1462 establish.
1463 + Add optional logging of transactions to sftp-server(8).
1464 + ssh(1) will now record port numbers for hosts stored in
1465 ~/.ssh/known_hosts when a non-standard port has been requested
1466 (closes: #50612).
1467 + Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
1468 non-zero exit code) when requested port forwardings could not be
1469 established.
1470 + Extend sshd_config(5) "SubSystem" declarations to allow the
1471 specification of command-line arguments.
1472 + Replacement of all integer overflow susceptible invocations of
1473 malloc(3) and realloc(3) with overflow-checking equivalents.
1474 + Many manpage fixes and improvements.
1475 + Add optional support for OpenSSL hardware accelerators (engines),
1476 enabled using the --with-ssl-engine configure option.
1477 + Tokens in configuration files may be double-quoted in order to
1478 contain spaces (closes: #319639).
1479 + Move a debug() call out of a SIGCHLD handler, fixing a hang when the
1480 session exits very quickly (closes: #307890).
1481 + Fix some incorrect buffer allocation calculations (closes: #410599).
1482 + ssh-add doesn't ask for a passphrase if key file permissions are too
1483 liberal (closes: #103677).
1484 + Likewise, ssh doesn't ask either (closes: #99675).
1485 - 4.6/4.6p1 (http://www.openssh.org/txt/release-4.6):
1486 + sshd now allows the enabling and disabling of authentication methods
1487 on a per user, group, host and network basis via the Match directive
1488 in sshd_config.
1489 + Fixed an inconsistent check for a terminal when displaying scp
1490 progress meter (closes: #257524).
1491 + Fix "hang on exit" when background processes are running at the time
1492 of exit on a ttyful/login session (closes: #88337).
1493 * Update to current GSSAPI patch from
1494 http://www.sxw.org.uk/computing/patches/openssh-4.6p1-gsskex-20070312.patch;
1495 install ChangeLog.gssapi.
1496 * Build the .deb --with-ssl-engine (closes: #408027, LP: #119295).
1497 * Use LSB functions in init scripts, and add an LSB-style header (partly
1498 from Ubuntu and partly thanks to Christian Perrier; closes: #389038).
1499 * Move init script start links to S16, move rc1 stop link to K84, and
1500 remove rc0 and rc6 stop links altogether (the last part from Ubuntu;
1501 closes: #122188).
1502 * Emit a slightly more informative message from the init script if
1503 /dev/null has somehow become not a character device (closes: #369964).
1504 * Belatedly build-depend on zlib1g-dev (>= 1:1.2.3-1) (closes: #333447).
1505 * Merge from Ubuntu:
1506 - Build position-independent executables (only for debs, not for udebs)
1507 to take advantage of address space layout randomisation.
1508 - If building on Ubuntu, add /sbin, /usr/sbin, and /usr/local/sbin to
1509 the default path.
1510 * Use ${binary:Version} rather than ${Source-Version} in openssh-server ->
1511 openssh-client dependency.

1585 GSSAPICleanupCredentials. Mark GSSUseSessionCCache and
1586 GSSAPIUseSessionCredCache as known-but-unsupported options, and migrate
1587 away from them on upgrade.
1588 * It turns out that the people who told me that removing a conffile in the
1589 preinst was sufficient to have dpkg replace it without prompting when
1590 moving a conffile between packages were very much mistaken. As far as I
1591 can tell, the only way to do this reliably is to write out the desired
1592 new text of the conffile in the preinst. This is gross, and requires
1593 shipping the text of all conffiles in the preinst too, but there's
1594 nothing for it. Fortunately this nonsense is only required for smooth

1661 time expired (closes: #389995).

1663 signal handler was vulnerable to a race condition that could be
1664 exploited to perform a pre-authentication denial of service. On
1665 portable OpenSSH, this vulnerability could theoretically lead to

1711 * New upstream release (closes: #361032).
1712 - CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
1713 subshell to perform local to local, and remote to remote copy
1714 operations. This subshell exposed filenames to shell expansion twice;
1715 allowing a local attacker to create filenames containing shell
1716 metacharacters that, if matched by a wildcard, could lead to execution
1717 of attacker-specified commands with the privilege of the user running
1718 scp (closes: #349645).
1719 - Add support for tunneling arbitrary network packets over a connection
1720 between an OpenSSH client and server via tun(4) virtual network
1721 interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
1722 between the client and server providing real network connectivity at
1723 layer 2 or 3. This feature is experimental.
1724 - Reduce default key length for new DSA keys generated by ssh-keygen
1725 back to 1024 bits. DSA is not specified for longer lengths and does
1726 not fully benefit from simply making keys longer. As per FIPS 186-2
1727 Change Notice 1, ssh-keygen will refuse to generate a new DSA key
1728 smaller or larger than 1024 bits.
1729 - Fixed X forwarding failing to start when the X11 client is executed in
1730 background at the time of session exit.
1731 - Change ssh-keygen to generate a protocol 2 RSA key when invoked
1732 without arguments (closes: #114894).
1733 - Fix timing variance for valid vs. invalid accounts when attempting
1734 Kerberos authentication.
1735 - Ensure that ssh always returns code 255 on internal error
1736 (closes: #259865).
1737 - Cleanup wtmp files on SIGTERM when not using privsep.
1738 - Set SO_REUSEADDR on X11 listeners to avoid problems caused by
1739 lingering sockets from previous session (X11 applications can
1740 sometimes not connect to 127.0.0.1:60xx) (closes:
1741 https://launchpad.net/bugs/25528).
1742 - Ensure that fds 0, 1 and 2 are always attached in all programs, by
1743 duping /dev/null to them if necessary.
1744 - Xauth list invocation had bogus "." argument.
1745 - Remove internal assumptions on key exchange hash algorithm and output
1746 length, preparing OpenSSH for KEX methods with alternate hashes.
1747 - Ignore junk sent by a server before it sends the "SSH-" banner.
1748 - Many manual page improvements.
1749 - Lots of cleanups, including fixes to memory leaks on error paths and
1750 possible crashes.
1751 * Update to current GSSAPI patch from
1752 http://www.sxw.org.uk/computing/patches/openssh-4.3p2-gsskex-20060223.patch
1753 (closes: #352042).
1754 * debian/rules: Resynchronise CFLAGS with that generated by configure.
1755 * Restore pam_nologin to /etc/pam.d/ssh; sshd no longer checks this itself
1756 when PAM is enabled, but relies on PAM to do it.
1757 * Rename KeepAlive to TCPKeepAlive in default sshd_config
1758 (closes: #349896).
1759 * Rephrase ssh/new_config and ssh/encrypted_host_key_but_no_keygen debconf
1760 templates to make boolean short descriptions end with a question mark
1761 and to avoid use of the first person.

1859 port forwardings when no listen address was explicitly specified
1860 (closes: #326065).

1862 credentials. This code is only built in openssh-krb5, not openssh, but
1863 I mention the CVE reference here anyway for completeness.
1864 - Add a new compression method ("Compression delayed") that delays zlib
1865 compression until after authentication, eliminating the risk of zlib
1866 vulnerabilities being exploited by unauthenticated users. Note that
1867 users of OpenSSH versions earlier than 3.5 will need to disable
1868 compression on the client or set "Compression yes" (losing this

2000 - ssh and ssh-keyscan now support hashing of known_hosts files for
2001 improved privacy (CAN-2005-2666). ssh-keygen has new options for
2002 managing known_hosts files, which understand hashing.
2003 - sftp supports command history and editing support using libedit
2004 (closes: #287013).
2005 - Have scp and sftp wait for the spawned ssh to exit before they exit
2006 themselves, allowing ssh to restore terminal modes (closes: #257130).
2007 - Improved the handling of bad data in authorized_keys files,
2008 eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
2009 in keys only produce errors in auth.log now (closes: #220726).
2010 - Add "command mode" to ssh connection multiplexing (closes: #303452).
2011 - Mention $HOME/.hushlogin in sshd(8) FILES section (closes: #163933).
2012 * Make gnome-ssh-askpass stay above other windows (thanks, Liyang HU;

2014 * Remove obsolete and unnecessary ssh/forward_warning debconf note.
2015 * Hurd build fixes (although sshd still doesn't work):
2016 - Restore X forwarding fix from #102991, lost somewhere along the way.
2017 - Link with -lcrypt.
2018 - Link with -lpthread rather than -pthread.
2019 - Don't build ssh-askpass-gnome on the Hurd, until GNOME is available to
2020 satisfy build-dependencies.
2021 * Drop workaround for #242462 on amd64; it's been fixed properly upstream.
2022 * Enable HashKnownHosts by default. This only affects new entries; use
2023 'ssh-keygen -H' to convert an entire known_hosts file to hashed format.
2024 * Note in ssh_config(5) that the SetupTimeOut option is Debian-specific
2025 (closes: #307069).

2134 * Split the ssh binary package into openssh-client and openssh-server
2135 (closes: #39741). openssh-server depends on openssh-client for some
2136 common functionality; it didn't seem worth creating yet another package
2137 for this. openssh-client is priority standard, openssh-server optional.
2138 * New transitional ssh package, priority optional, depending on
2139 openssh-client and openssh-server. May be removed once nothing depends
2140 on it.
2141 * When upgrading from ssh to openssh-{client,server}, it's very difficult
2142 for the maintainer scripts to find out what version we're upgrading from
2143 without dodgy dpkg hackery. I've therefore taken the opportunity to move
2144 a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
2145 and ssh/user_environment_tell.
2146 * Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
2147 happens even though we don't know what version we're upgrading from.
2148 * Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
2149 (until sarge+2) it's still honoured to avoid breaking existing
2150 configurations, but the right approach is now to remove the
2151 openssh-server package if you don't want to run the server. Add a NEWS

2321 - New PAM implementation based on that in FreeBSD. This runs PAM session
2322 modules before dropping privileges (closes: #132681, #150968).
2323 - Since PAM session modules are run as root, we can turn pam_limits back
2324 on by default, and it no longer spits out "Operation not permitted" to
2325 syslog (closes: #171673).
2326 - Password expiry works again (closes: #153235).
2327 - 'ssh -q' suppresses login banner (closes: #134589).
2328 - sshd doesn't lie to PAM about invalid usernames (closes: #157078).
2329 - ssh-add prints key comment on each prompt (closes: #181869).
2330 - Punctuation formatting fixed in man pages (closes: #191131).
2331 - EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
2332 * Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
2333 than this, to maintain the standard Debian sshd configuration.
2334 * Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
2335 sshd_config on upgrade. Neither option is supported any more.
2336 * Privilege separation and PAM are now properly supported together, so
2337 remove both debconf questions related to them and simply set it
2338 unconditionally in newly generated sshd_config files (closes: #228838).
2339 * ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
2340 compatibility alias. The semantics differ slightly, though; see
2341 ssh_config(5) for details.
2342 * Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
2343 documented in ssh_config(5), it's not as good as the SSH2 version.
2344 * Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and
2345 -D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary.
2346 * Update config.guess and config.sub from autotools-dev 20040105.1.

2390 * Update config.guess and config.sub from autotools-dev 20031007.1
2391 (closes: #217696).
2392 * Implement New World Order for PAM configuration, including
2393 /etc/pam.d/common-* from /etc/pam.d/ssh (closes: #212959).
2394 - To backport this release to woody, you need to set DEB_BUILD_SSH_WOODY
2395 in your environment. See README.Debian.
2396 * Add more commentary to /etc/pam.d/ssh.

2517 the whole thing, and remove the directory if that leaves it empty
2518 (closes: #176679).
2519 * ssh has depended on debconf for some time now with no complaints, so:
2520 - Simplify the postinst by relying on debconf being present. (The absent
2521 case was buggy anyway.)
2522 - Get rid of "if you have not installed debconf" text in README.Debian,
2523 and generally update the "/usr/bin/ssh not SUID" entry.
2524 * More README.Debian work:
2525 - Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
2526 make it easier for people to find the former. The upgrade issues
2527 should probably be sorted by version somehow.
2528 - Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).

2548 of other merged bugs).
2549 - ssh-copy-id prints usage when run without arguments (closes: #71376).

2551 - sshd writes to utmp's ut_addr_v6 field in IPv6 mode (closes: #167867).

2564 nice, but that belongs to another package. Without a defined API to
2565 retrieve its settings, parsing it is off-limits.

2576 previously it was completely wrong anyway.
2577 * Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
2578 question's default using that information, rather than using debconf as
2579 a registry. Other solutions may be better in the long run, but this is
2580 at least correct (thanks, Matthew Woodcraft; closes: #84725).
2581 * Stop using pam_lastlog, as it doesn't currently work well as a session
2582 module when privilege separation is enabled; it can usually read
2583 /var/log/lastlog but can't write to it. Instead, just use sshd's
2584 built-in support, already enabled by default (closes: #151297, #169938).

2587 installation (part of #110094).
2588 * When restarting via the init script, check for sshd_not_to_be_run after
2589 stopping sshd (idea from Tomas Pospisek; closes: #149850).

2643 sshd_config.
2644 - ssh-agent is installed setgid to prevent ptrace() attacks. The group
2645 actually doesn't matter, as it drops privileges immediately, but to
2646 avoid confusion the postinst creates a new 'ssh' group for it.
2647 * Obsolete patches:

3442 -> ssh-nonfree -> openssh. Without these, debconf remembered
3443 the old answer, config didn't force asking it, and preinst always
3444 aborted (closes: #56596, #57782)

3446 where preinst would abort. This means no double question to most
3447 users, people who currently suffer from "can't upgrade" may need
3448 to run apt-get install ssh twice. Did not do the same for

10The Debian-specific parts of the package were initially derived from the
11original ssh package, which has since been renamed as ssh-nonfree.
12
13The Debian patch is distributed under the terms of the GPL, which you
14can find in /usr/share/common-licenses/GPL-2.
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
22modify this file, you may extend this exception to your version of the
23file, but you are not obligated to do so. If you do not wish to do
24so, delete this exception statement from your version.

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
31credited in /usr/share/doc/ssh/README.

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.

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.
189
190
191<p>
192Businesses have trade secrets, patent applications in preparation,
193pricing information, subcontractor information, client data, personnel
194data, financial information, etc. Currently, anyone with access to
195the network (any machine on the network) can listen to anything that
196goes in the network, without any regard to normal access restrictions.
197
198
199<p>
200Many companies are not aware that information can so easily be
201recovered from the network. They trust that their data is safe
202since nobody is supposed to know that there is sensitive information
203in the network, or because so much other data is transferred in the
204network. This is not a safe policy.

240<h2><a name= "1.4">1.4 - What about copyrights, usage and patents?</a></h2>
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">

296 </td>
297 </tr>
298</table>
299</blockquote>
300
301<p>
302Or you can specify this option on the command line, using the <b>-o</b>
303option to
304<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssh&amp;sektion=1">ssh(1)</a> command.
305

312 </tr>
313</table>
314</blockquote>
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>.
353
354

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>.
376
377
378<blockquote>

388<h2><a name= "2.5">2.5 - Old versions of commercial SSH encrypt host keys with IDEA.</a></h2>
389
390<p>
391The old versions of SSH used a patented algorithm to encrypt their

393<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&amp;sektion=8">sshd(8)</a>

415Commercial SSH's
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").
427
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>:
434
435<blockquote>

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.
474

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'':

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">

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.

657<h2><a name= "2.14">2.14 - Why does OpenSSH report its version to clients?</a></h2>
658
659<p>
660OpenSSH, like most SSH implementations, reports its name and version to clients
661when they connect, e.g.
662</p>
663
664<blockquote>
665SSH-2.0-OpenSSH_3.9
666</blockquote>
667
668<p>
669This information is used by clients and servers to enable protocol
670compatibility tweaks to work around changed, buggy or missing features in
671the implementation they are talking to. This protocol feature checking is
672still required at present because versions with incompatibilities are still
673in wide use.

677
678<h2><a name= "3.1">3.1 - Spurious PAM authentication messages in logfiles.</a></h2>
679
680<p>
681The portable version of OpenSSH will generate spurious authentication
682failures at every login, similar to:
683
684
685<blockquote>
686<table border=0 width="800">
687 <tr>
688 <td nowrap bgcolor="#EEEEEE">
689&quot;<b>authentication failure; (uid=0) -&gt; root for sshd service</b>&quot;
690 </td>
691 </tr>
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">
715 <tr>
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
733users access to the account regardless of the policy specified by
734<b>PermitEmptyPasswords</b>. For this reason, it is recommended that you
735do not add the <b>nullok</b> directive to your PAM configuration file
736unless you specifically wish to allow empty passwords.

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

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

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">

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.

1150<a name= "3.15fn1">[1]</a> Some vendors, notably Redhat/Fedora, have
1151backported the PasswordAuthentication from 3.9p1 to their 3.8x based
1152packages. If you're using a vendor-supplied package then consult their
1153documentation.
1154
1155<p>
1156OpenSSH Portable's PAM interface still has problems with a few modules,
1157however we hope that this number will reduce in the future. As at the
11583.9p1 release, the known problems are:
1159
1160<ul>
1161 <li>Modules relying on module-private data (eg pam_dhkeys, pam_krb5, AFS)
1162 may fail to correctly establish credentials (bug <a
1163 href="http://bugzilla.mindrot.org/show_bug.cgi?id=688">#688</a>) when
1164 authenticating via <b>ChallengeResponseAuthentication</b>.
1165 <b>PasswordAuthentication</b> with 3.9p1 and above should work.
1166</ul>
1167
1168You can also check <a
1169href="http://bugzilla.mindrot.org/buglist.cgi?product=Portable+OpenSSH&amp;bug_status=RESOLVED&amp;bug_status=NEW&amp;bug_status=ACCEPTED&amp;component=PAM+support"

1172<h2><a name= "3.16">3.16 - Why doesn't "w" or "who" on AIX 5.x show users
1173logged in via ssh?</a></h2>
1174
1175Between AIX 4.3.3 and AIX 5.x, the format of the wtmp struct changed. This
1176means that sshd binaries built on AIX 4.x will not correctly write wtmp
1177entries when run on AIX 5.x. This can be fixed by simply recompiling
1178sshd on an AIX 5.x system and using that.

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
50.B x11\-ssh\-askpass
51by Philip Hands.

4Subject: Various Debian-specific configuration changes
5
6ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause
7fewer problems with existing setups (http://bugs.debian.org/237021).
8
9ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024).
10
11ssh: Enable HashKnownHosts by default to try to limit the spread of ssh
12worms.
13
14ssh: Enable GSSAPIAuthentication and disable GSSAPIDelegateCredentials by
15default.
16
17sshd: Refer to /usr/share/doc/openssh-server/README.Debian.gz alongside
18PermitRootLogin default.

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

4Subject: Various keepalive extensions
5
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.
12
13Adjust documentation to match and to give some more advice on use of
14keepalives.

4Subject: Fix picky lintian errors about slogin symlinks

6Apparently this breaks some SVR4 packaging systems, so upstream can't win
7either way and opted to keep the status quo. We need this patch anyway.

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.

7I (Colin Watson) agree with Vincent and think it does.

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

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.

41.Sh DESCRIPTION
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.

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.
