[X2Go-User] How to purge zombie sessions after a user is deleted

[Walid MOGHRABI]

Just  go on the X2Go server and do x2goterminate-session <session id>

For exmple, in  your case : 

x2goterminate-session trainer1-51-1502204631_stDXFCE_dp32

Objet: [X2Go-User] How to purge zombie sessions after a user is deleted 


I am not sure if this is a bug, but it looks like x2gocleansessions keeps trying to open some previously saved session created by a deleted user. This leaves a log like the following in the /var/log/auth.log and this log continues to add in an infinite loop 


Aug 22 18:17:32 taote su[6146]: - ??? root:trainer7 
Aug 22 18:17:32 taote su[6147]: No passwd entry for user 'trainer7' 
Aug 22 18:17:32 taote su[6147]: FAILED su for trainer7 by root 


if I kill the x2gocleansessions process, the log stops. 


if I run 



sudo /usr/sbin/x2golistsessions_root 


I can see the two zombie sessions

but could not find a way to purge then. Those two user accounts (trainer1 and trainer7) were created for an event previously, but after the event, both accounts have been deleted. 


A reboot does not solve the issue. As long as you run "sudo service x2goserver restart", the error log comes back and keeps repeating itself. 


Can someone suggest a way to purge these zombie sessions so that I don't see the error logs again? 


thanks
