Subject: x2goserver update to 4.0.1.16 breaks x2go

Date: Thu, 2 Oct 2014 10:49:13 +0200

Package: x2goserver
Version: 4.0.1.16-0~935~ubuntu14.04.1

After the apt update to x2goserver 4.0.1.16 it is not possible to create new connections to the x2goserver. It must be connected to the modifications in the location of the session directories.
There was no server restart after the update (and can also not be executed), there were suspended and active sessions from the old x2goserver.
Any try to create a new connection ends up with the client status hang during "Starting" followed up by a time out error after a while.
The syslog is filled with messages like this:
Oct  2 08:28:12 ikkatrinsrv1 /usr/sbin/x2gocleansessions[12589]: neumann-77-1411537406_stRxfce4-terminal_dp32: state file for this session does not exists: /tmp/.x2go-neumann/C-neumann-77-1411537406_stRxfce4-terminal_dp32/state (this can be ignored during session startups)

The system is an Ubuntu 14.04.1 LTS on the most recent state. These other x2goserver related packages (x2goserver-extensions, x2goserver-fmbindings, x2goserver-printing, x2goserver-xsession) are also installed and at version 4.0.1.16. The remaining server configuration is complex using LDAP users and tmpreaper to regularly clean up tmp - but these directories are protected from clean-up '/tmp/.X11-unix /tmp/.x2go*'. It always worked with 4.0.1.15 and I truly liked the functionality of the x2go software.

This is a severe issue. I though this to be fixed [1], but just now  
found two other places (in x2golistsessions and x2golistsessions_root)  
where the X2Go Server can break running (non-state-file) sessions.

Are you able to and available for build(ing)+install(ing) x2goserver  
4.0.1.17-pre from Git for a test run (things cannot get worse for  
you...)?

Please grab these to files from Git:

/usr/sbin/x2golistsessions_root:
http://code.x2go.org/gitweb?p=x2goserver.git;a=blob_plain;f=x2goserver/sbin/x2golistsessions_root;h=d562fa3140ef9fc523f9e5283f183f9e36639026;hb=a13accdd301d8096f95431dfc778cbb3e01d1926

/usr/bin/x2golistsessions:
http://code.x2go.org/gitweb?p=x2goserver.git;a=blob_plain;f=x2goserver/bin/x2golistsessions;h=dc78ec349e49063f0a97bcd3a3fb8817ae3e87e7;hb=a13accdd301d8096f95431dfc778cbb3e01d1926

Replace those two files on your system with the version currently in  
Git (release/4.0.1.x branch) and report back if that fixes session  
startup for you.

Thanks,
Mike

Date: Thu, 2 Oct 2014 12:21:56 +0200

Hello Mike,

I agree it is a severe problem. Please notice that the effect was vice versa to your comment: Old sessions continued running with no effect but it was not possible to start new sessions. I have no idea how the running session and in-memory binaries and libraries might have contributed to the effect (maybe a system restart would have helped, a restart of /etc/init.d/x2goserver did NOT help).
I am sorry I cannot help further with beta-experiments. It is a productive remote system for science with 20+ active users. To resolve the issue asap I turned to the Baikal LTS ppa and installed the x2goserver 4.0.0.11. It resolved all issues immediately.

Kind regards,
Martin
