Various Debian-specific configuration changes
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. 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. Document all of this. Author: Russ Allbery <rra@debian.org> Forwarded: not-needed Last-Update: 2016-12-26 Patch-Name: debian-config.patch
