Bug#323: x2go server refuses client with 'Error: Wrong version or invalid session authentication cookie.'
Package: x2goserver Version: 4.0.1 x86_64, CentOS 6.4, kernel 2.6.32-358.18.1.el6.centos.plus.x86_64
(also x2go version 4.0.1.6 (self-compiled) on the same platform)
Problem: After a server OS lockup and reboot, the previously working x2goserver would not allow client connections from Mac, Linux, Windows. After re-installing x2gserver (x2goserver-4.0.1.6-1.1.x86_64) and x2goagent (x2goagent-3.5.0.20-4.1.x86_64), it refused to connect with the client-side message:
=== Session: Starting session at 'Fri Oct 11 18:11:36 2013'. Info: Connecting to remote host 'localhost:31030'. Info: Connection to remote proxy 'localhost:31030' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Fri Oct 11 18:11:37 2013'. Session: Session terminated at 'Fri Oct 11 18:11:37 2013'.
(dont know if this is complete since the popup only lasts 2s.) This error has been cited multiple times in various fora and lists, but no one seems to have been able to solve it.
I can passwordlessly ssh to both servers just fine from other Linux clients.
If I don't use the ssh keys, I can enter my password and the result is the same.
The server seems to be initializing the session since if I try to log in multiple times, there are new sessions listed, but I'm not allowed to connect to them. I can only terminate or suspend them.
Terminating them does appear to work since they are not listed on following sessions if I do.
The problem does seem to be related to authentication or authorization; we use ldap-based auth on the server and it's working fine otherwise, except for x2go.
Thanks for your work!

ok... so there was a server crash. Of course, X2Go Server should
handle crashes in most occasions, but sometimes the X2Go session DB
indeed can become corrupt.
Please try
$ sudo rm -f /var/lib/x2go/x2go_sessions $ sudo x2godbadmin --createdb
Does that solve your problems?

Is every user affected??? Can you test with a fresh user account on
the server??? We need to pin down, whether something on the server is
broken system wide or if the issue is a user profile problem.
Thanks for your work!
