Public bug reported: I had a proper configuration on jaunty (sshd_config) so I could ssh into that machine and run X11 applications there with X11 forwarding, so I could use apps fromt here remotely. After upgrade to karmic (same sshd_config on the server, client is not changed) I got this (for example):
xterm Xt error: Can't open display: xterm: DISPLAY is not set I've tried ssh -X, -Y and -X -Y too together with no success. So DISPLAY environment variable is not even set because of some reason, though I found this in /var/log/auth.log: Sep 22 19:56:02 vega sshd[11206]: error: Failed to allocate internet- domain X11 display socket. openssh-server: Installed: 1:5.1p1-6ubuntu1 Candidate: 1:5.1p1-6ubuntu1 Version table: *** 1:5.1p1-6ubuntu1 0 500 http://archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status xauth: Installed: 1:1.0.3-2 Candidate: 1:1.0.3-2 Version table: *** 1:1.0.3-2 0 500 http://archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status sshd_config file: Port 22 ListenAddress 0.0.0.0 Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key UsePrivilegeSeparation yes KeyRegenerationInterval 3600 ServerKeyBits 768 SyslogFacility AUTH LogLevel INFO LoginGraceTime 600 StrictModes yes RSAAuthentication yes PubkeyAuthentication yes IgnoreRhosts yes RhostsRSAAuthentication no HostbasedAuthentication no PermitEmptyPasswords no PasswordAuthentication no X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes Subsystem sftp /usr/lib/openssh/sftp-server UsePAM yes PermitTunnel yes PermitRootLogin forced-commands-only ** Affects: openssh (Ubuntu) Importance: Undecided Status: New -- X11 forwarding via SSH does not work after upgrade to karmic https://bugs.launchpad.net/bugs/434799 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
