Could you cross-check the debug output of X2Go Server, possibly add some mo= re log message to /usr/bin/x2gostartagent, so that we can narrow down, wher= e the "hang" actually occurs?

Does x2gostartagent get executed at all, or is X2Go Client aready stalling = before executing that command.

Or is x2gostartagent hanging somewhere on the way? (Extra log messages plac= ed in x2gostartagent will be helpful then).

Mike

With some debug= within the x2gostartagent I can tell that it is executing this script and = now seems to be getting past this point. I have turned the logging level of= the server to debug and here is the output I am seeing during a connection= attempt:

Oct 29 08:02:33 oddjob /usr/bin/x2goli= stsessions[12799]: x2golistsessions has been called with no option

I added some more debug messages to x2golistsessions and a= m seeing that this script seems to finish execution (I reach deubg statemen= ts just before closing syslog).
