[Bug 434799] Re: X11 forwarding via SSH does not work after upgrade to karmic
I've been unable to recreate this bug when ssh'ing from an Jaunty system using openssh-client version 1:5.1p1-5ubutu1 to a Karmic system with openssh-server version 1:5.1p1-6ubuntu1. Could you please set the LogLevel to DEBUG on the server and include '/var/log/auth.log' with the failure? Additionally what openssh client are you using? ** Changed in: openssh (Ubuntu) Importance: Undecided = Low ** Changed in: openssh (Ubuntu) Status: New = Incomplete -- 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
[Bug 434799] Re: X11 forwarding via SSH does not work after upgrade to karmic
I unable to reproduce it either, but it was reproducable then. So I suppose this bug is already fixed and/or there was some problem with my config. I set the status to invalid then, if it's OK.

[Bug 434799] Re: X11 forwarding via SSH does not work after upgrade to karmic
Also I am not sure if it's related but if I do X forwarding via SSH _from_ that karmic box, it works, but I got this message too: Warning: No xauth data; using fake authentication data for X11 forwarding. But sine it works anyway it does not matter too much for me, the problem is about starting X apps on this box and have the forwarded X11 output on another machine. -- 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
