1Description: Various Debian-specific configuration changes
2 ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause
3 fewer problems with existing setups (http://bugs.debian.org/237021).
4 .
5 ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024).
6 .
7 ssh: Enable HashKnownHosts by default to try to limit the spread of ssh
8 worms.
9 .
10 ssh: Enable GSSAPIAuthentication and disable GSSAPIDelegateCredentials by
11 default.
12 .
13 sshd: Refer to /usr/share/doc/openssh-server/README.Debian.gz alongside
14 PermitRootLogin default.
15 .
16 Document all of this, along with several sshd defaults set in
17 debian/openssh-server.postinst.
