+From a433d9baa031d7136a8cf3e3807ebff83a3a8634 Mon Sep 17 00:00:00 2001
+From: Colin Watson <cjwatson@debian.org>
+Date: Sun, 9 Feb 2014 16:10:18 +0000
+Subject: 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.
