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'.
