Hi Anders,

Thank you for your prompt reply.

As a note of interest, /usr/libexec/x2go is the correct directory it seems:

However, there are also files in /usr/lib64/x2go/

-rw-r--r--.  1 root root  1834 May 19 01:02 x2gologlevel.pm
[root@local ~]#

I think this is where things are getting interesting.

On my systems it returns /usr/lib/x2go, which is where x2gologlevel.pm is located. /usr/sbin/x2gocleansessions uses "x2gopath libexec" to get which paths it needs to search for the needed perl modules. Why x2gopath returns that path on your system is beyond me - I generally only run Ubuntu on my systems :)
It is really quite weird, as /usr/bin/x2gopath (at least on my systems) doesn't even seem capable of returning a path like the one you are getting. A workaround would probably be to make /usr/libexec/x2go a symlink to /usr/lib64/x2go. I do however think it would be a good idea to find out why this is happening, as other CentOS users might run into the same problem, and it might be preventable in the code.

Hi Jan,

Can you post the output of: "x2gopath libexec"?

Hi Anders,

Thank you for your reply.  Sorry for not getting back to you earlier.

I definitely do not have an SSH proxy configured in the x2goclient.

If you have any other suggestions or things I might try, please let me know. 
Kindest regards,

Hi Jan,

The output from x2goclient indicates that it is trying to use an SSH proxy. Can you double check that your x2go session doesn't have SSH proxying enabled? (Go to Session Preferences and make sure that "Use Proxy server for SSH connection" isn't chosen)

Hello!

After not getting freenx working properly on a clean install of CentOS 6.4, someone advised me to install x2go server.  I was surprised by the ease of installation, using the RHEL6 repository.  Using an x2go client on Ubuntu 12.04 to connect, things worked fantastic out of the box.

However, after a reboot of the CentOS 6.4 machine, the client can no longer connect.  I've presented this issue to #x2go on Freenode, where sunweaver was gracious enough to provide some useful information.  He advised me to post about my issue on this mailing list.

After an unsuccessful connection attempt, this is in /var/log/syslog with debug log level:  http://pastebin.com/L3e4xP6g  The x2go client says:  http://pastebin.com/CiGatMeS  When I connect, I get those errors. When I re-connect it shows an active session, but I can't resume it.  I can start a new one, but then the same thing happens as the first time.  The error message shows up and next time there's 2 sessions in the session popup during login.

Per sunweaver's suggestions, I've tried   rm -f /var/lib/x2go/x2go_sessions  and  x2godbadmin --createdb   but that didn't solve the problem.  There is also no process x2gocleansessions running.  There is nothing actually running with x2go in the name (ps aux | grep x2go returns nothing).  When starting x2gocleansessions manually, I get:  http://pastebin.com/fExxSJ5p

Another suggestion was to create a brand new user account, but there I get the same error as with the other user account.  I've tried a fresh account on both server and client.

About the not locating x2gologlevel.pm bit (the x2gocleansessions error)... seems like it's include path is insufficient.  The file is in /usr/lib64/x2go/x2gologlevel.pm.  Not sure how to fix that and if it's indication of bigger problems.  Also interesting... in the sudoers file there's a reference to /usr/bin/x2gopgwrapper, but this executable does not exist.

If you have any suggestions on things which I could try that might shed further light on this, please let me know.

Also, the machine that's plagued with this issue is a fresh installation, with nothing sensitive, critical or even mildly important running there yet.  I could provide you with ssh access to this machine so you can have a look around and/or attempt to connect.  If that helps, please find me on irc.freenode.net in #x2go under nickname Hyperbyte, so we can work something out.

Kindest regards,
Jan Middelkoop
