Sorry for the post in German. The password error message is different, I tried that. I am not aware of any other differences to a normal 9.10 apart from the ssh port. The first ssh contact appears to work. I am asked if the ssh host key is not verified.
I deleted the content of.x2go, which did not help.
The individual session logs look like this.
/usr/bin/x2goagent: Zeile 1: -e: Kommando nicht gefunden.

I found the following errors in In /var/log/auth.log

Any other ideas anyone?

Hi Alexander,
please post in English to this list as there are several competent people listening on this list that do not speak German.

Hallo,
"The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server.".
This error occurs indeed if your password is not typed in correctly. I sometimes also get this error (no idea why...), even if I am really sure that I typed my pw in correctly... But this error should not be permanent and it occurs rather rarely.
On your x2goserver system take a look at /var/log/auth.log while you try to login.
As well the client as the x2goserver produces log output in your local and your remote home dir (~/.x2go). Also check output and information there...
Ab und zu sehe ich noch das hier " NXPROXY - Version 3.4.0

Maybe you should clean up the sessions (C-<uid>-<displayno>-<long-alnum-string>) in your remote ~/.x2go dir.
In a nutshell:
watch /var/log/auth.log clear local .x2go dir clear remote .x2go dir look at individual session logs in .x2go (remotely+locally) post your insights
Normal x2goserver-home works out of the box on Ubuntu karmic (my experience). Do you have a firewall running? Any other tweaks / differences from a standard ubuntu desktop?
Greets and good luck, Mike
