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!

Of course, X2Go Server should handle crashes in most occasions, but sometimes the X2Go session DB indeed can become corrupt.

All packages coming from the ppa:x2go/stable I tried this: 1/ sudo rm -f /var/lib/x2go/x2go_sessions sudo x2godbadmin --createdb 2/ creating a new ssh user on the server, and trying to connect with this new one. x2go detected the /home/my_new_user folder was missing, and when I created it, x2go refused to connect any longer. 3/ editing / renaming ~/.ssh/known_hosts from the client side (according to http://john.wesorick.com/2011/11/issues-installing-x2go.html I also commented the "HostKey /etc/ssh/ssh_host_ecdsa_key" in my sshd_config on the server) none of them worked. I also renamed the ~/.x2go/ ~/.x2goclient/ folders in my home I can barely copy the output from the error window ( it hides itself too quickly and can't find a way to get it from elsewhere) : Starting session at 'Fri Nov 1 13:28:55 2013'. Info: Connecting to remote host 'localhost:31004'. Info: Connection to remote proxy 'localhost:31004' 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 Nov 1 13:28:56 2013'. Session: Session terminated at 'Fri Nov 1 13:28:56 2013'. (I don't understand why it tries to connect to localhost) My log in ~/.x2go/S-mylogin-50-1383308923_stDLXDE_dp24/sessions says: Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. x2go worked perfectly before, I can't trace when it stopped working but it's probably after some package updates.

Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. I solved it in my case. The reason was a wrong writing permission in the appropriate directory where the client logged in. This is certainly not a bug but a mistake, - and a trace to look at for the the one or other case with this error.

The /tmp folder was in read write access for everyone but it complained it was needed to set the /tmp/.X11-unix/ folder to 1777, which I did, and now it's working again. The error message from the client was not really helpfull. I noticed the problem when trying to start x2goagent from the commandline on the server: _XSERVTransmkdir: ERROR: Mode of /tmp/.X11-unix must be set to 1777 _XSERVTransSocketUNIXCreateListener: mkdir(/tmp/.X11-unix) failed, errno = 9 _XSERVTransMakeAllCOTSServerListeners: failed to create listener for local So there is a process on my computer which is changing the rights on my /tmp folder but I don't know which one at the moment...
