Hi Mike,

I did some more digging. 

The start up script, /etc/init.d/x2gocleansessions, has what it needs to create the directory /tmp/.X11-unix.  However, that script does not seem to be run during system startup on my very minimal CentOS v6.4 servers.

Running "chkconfig --list | grep x2go" does not come up with anything.  Chkconfig does not see it, so /etc/init.d/x2gocleansessions does not run even though it is in the correct directory.

I had to add it manually to chkconfig so it would run on system start up;

# chkconfig --add x2gocleansessions

Now chkconfig sees it as a script to run on system start up;

# chkconfig --list | grep x2go
x2gocleansessions    0:off    1:off    2:off    3:on    4:off    5:on    6:off

Now the start up script /etc/init.d/x2gocleansessions runs on system start up and creates /tmp/.X11-unix.

I looked at other application heavy CentOS v6 servers that we have x2go "working" on.  They work because it seems that some other application creates /tmp/.X11-unix during system start up.  These "working" machines also did not have x2gocleansessions running upon system start up.  I ran "chkconfig --add x2gocleansessions" on them as well.

If I have figured out the problem, it looks like the x2goserver installation script on CentOS v6 may need to have "chkconfig --add x2gocleansessions" run in it.

Thanks,
Frank

can you take a look at issue #332 in X2Go BTS. Obviously, you should add
something to the RPM package's init script of X2Go Server that resembles this

The init script is already whatever was in debian/x2goserver.init.



I have this in /etc/rc.d/rc.local on CentOS v6.4 64bit, so that after a reboot, x2goclient can still connect to the server;

/bin/mkdir -m 1777 /tmp/.X11-unix


As Jan stated, there should be an init script for X2Go Server. The script launches /usr/sbin/x2gocleansessions. It also should handled the /tmp/.X11-unix directory. Can you please check if that script is in place? Can you also check, why it does not work on your system? Thanks.
