Hello,
I was happily using x2go between my Debian server and my Debian desktop since a few months when things stopped suddenly working after an update of both Debian yesterday (I haven't updated them since beginning of october).
Debian server is with Debian stable (x2goserver) and Debian desktop is on Debian testing (x2goclient).
Here are the version installed: x2goclient: 3.99.3.0-0~x2go1+squeeze~main~321~build1 x2goserver: 3.1.1.6-0~x2go1+squeeze~main~610~build1
Here are the logs I am getting on Debian server: sshd[11491]: error: connect_to localhost port 30001: failed. sshd[11491]: error: connect_to localhost port 30001: failed. sshd[11491]: error: channel 0: protocol error: close rcvd twice sshd[12040]: Accepted publickey for user from 92.226.X.X port 55500 ssh2 sshd[12040]: pam_unix(sshd:session): session opened for user user by (uid=0) sshd[12079]: error: bind: Address already in use sshd[12079]: error: channel_setup_fwd_listener: cannot listen to port: 30002 sshd[12079]: Received disconnect from 92.226.X.X: 11: Bye Bye sshd[12040]: pam_unix(sshd:session): session closed for user user sshd[11491]: channel_by_id: 0: bad id: channel free sshd[11491]: Disconnecting: Received ieof for nonexistent channel 0. sshd[11483]: pam_unix(sshd:session): session closed for user user
And here are the logs I am getting on Debian desktop: 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.
I have checked that nothing is running on Debian server on port 30001 and I have restarted the SSH server, the x2go server and deleted .x2go directory on both Debian but errors are still the same.
Can someone help me debug this ?
Thanks
It could be a port conflict issue.
Are you using X2Go Client to simultaneously connect to several servers from the same client?
Are you using X2Go Client on the server to connect to another server?
Cheers, Daniel

Hello Daniel,
No my setup is quite simple: I have only one server and one client (and of course the server is on a different machine than the client) The client only connect to the server and the server has only one client. And I also got only one session.
Thanks !

On the server, please kill all x2goagent processes and check the all
x2goruncommand processes vanish soon after you have killed all
x2goagent instances.
If there is no x2goagent instance running... Hmmm...
Just in case: also restart sshd on the server.

Hello,
I have no x2goagent running on the server: ps af | grep x2 26924 pts/0 S 0:00 /usr/bin/perl /usr/sbin/x2gocleansessions
I tried stopping x2goserver and sshd and restarting them: same errors.
Is there any way I can have more meaningful messages to debug this ? I don't understand why the port 30001 seems to be occupied. I have nothing running behind that port.
Thanks for your help !
Hi, You could try a: netstat -anp | grep 30001
to see which process that is currently using the port.

Unless there are some firewalls involved it should work. Try uninstallinng X2Go on both client and server, example:
sudo apt-get -y remove --purge x2goserver x2goclient sudo apt-get -y autoremove --purge rm -rf ~/.nx/ ~/.x2go/ ~/.x2goclient/
Then install X2Go again and cross your fingers.
If it still doesn't work, try editing /usr/bin/x2gostartagent on the server and change SSH_PORT to 30500 and see if it changes anything.
I have the exact same setup (Wheezy client connecting to Squeeze server) and haven't had any similar problems.

Things are working perfectly as before. Wondering what was the problem ?

After an Update to the actual version on an OpenSUSE 12.1 box there is this error above. The client connection was fine befor. No multiple connections are using, nor a server to server connection. The previous version was: 3.1.1.2-2.1
x2goserver current: Version: 4.0.0.0-5.1 obs://build.opensuse.org/X11
Any suggestions for updates to other packages that depend to this or other?
PS: x2go is a very nice work! Thanks! It's fun to use it, if it works properly... ;-D
