2020-10-18Various Debian-specific configuration changesColin Watson
ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause fewer problems with existing setups (http://bugs.debian.org/237021). ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024). ssh: Enable HashKnownHosts by default to try to limit the spread of ssh worms. ssh: Enable GSSAPIAuthentication by default. ssh: Include /etc/ssh/ssh_config.d/*.conf. sshd: Enable PAM, disable ChallengeResponseAuthentication, and disable PrintMotd. sshd: Enable X11Forwarding. sshd: Set 'AcceptEnv LANG LC_*' by default. sshd: Change sftp subsystem path to /usr/lib/openssh/sftp-server. sshd: Include /etc/ssh/sshd_config.d/*.conf. Document all of this. Author: Russ Allbery <rra@debian.org> Forwarded: not-needed Last-Update: 2020-10-18 Patch-Name: debian-config.patch
2020-10-18GSSAPI key exchange supportSimon Wilkinson
This patch has been rejected upstream: "None of the OpenSSH developers are in favour of adding this, and this situation has not changed for several years. This is not a slight on Simon's patch, which is of fine quality, but just that a) we don't trust GSSAPI implementations that much and b) we don't like adding new KEX since they are pre-auth attack surface. This one is particularly scary, since it requires hooks out to typically root-owned system resources." However, quite a lot of people rely on this in Debian, and it's better to have it merged into the main openssh package rather than having separate -krb5 packages (as we used to have). It seems to have a generally good security history.

[ssh_config sshconnect2.c packet.c readconf.h readconf.c clientloop.c ssh_config.5 packet.h] Add an optional second argument to RekeyLimit in the client to allow rekeying based on elapsed time in addition to amount of traffic. with djm@ jmc@, ok djm
2010-01-12 - dtucker@cvs.openbsd.org 2010/01/11 01:39:46Darren Tucker
[ssh_config channels.c ssh.1 channels.h ssh.c] Add a 'netcat mode' (ssh -W). This connects stdio on the client to a single port forward on the server. This allows, for example, using ssh as a ProxyCommand to route connections via intermediate servers. bz #1618, man page help from jmc@, ok markus@

[auth-options.c auth-options.h channels.c channels.h clientloop.c] [misc.c misc.h readconf.c readconf.h scp.c servconf.c servconf.h] [serverloop.c sftp.c ssh.1 ssh.c ssh_config ssh_config.5 sshconnect.c] [sshconnect.h sshd.8 sshd_config sshd_config.5] Add support for tun(4) forwarding over OpenSSH, based on an idea and initial channel code bits by markus@. This is a simple and easy way to use OpenSSH for ad hoc virtual private network connections, e.g. administrative tunnels or secure wireless access. It's based on a new ssh channel and works similar to the existing TCP forwarding support, except that it depends on the tun(4) network interface on both ends of the connection for layer 2 or layer 3 tunneling. This diff also adds support for LocalCommand in the ssh(1) client. ok djm@, markus@, jmc@ (manpages), tested and discussed with others
