Tigervnc global timeout ?

[Patric...@legi.grenoble-inp.fr]

Hi,

I'm new with tigervnc on a RHEL6 large server. This software seams very powerfull and after a few days I begin to seen all that we can for our needs.

However i've some trouble with one concept and I do not find any help on googling:

The users launch vncserver and then connect with vncviewer from their laptop, but... many occurences of unused server are now runing on my computer. I've tryed to set autokill or idletimeout without success.

Is there a way to configure the vncserver to close automaticaly old unused Xvnc sessions ?

Thanks for your advices

Patrick

In which way? Are you using MaxIdleTime?

How are you starting the server? If it's a service then perhaps
something is restarting it when it terminates?

A typical session is:

- the user logon with ssh.
- he launch "vncserver"
- then he close his connection and launch vcnviewer from his PC.

I've nearly 10 users (Phd students) allowed to use this server and the goal is
to use a meshing software to build large meshes for CFD applications and for now
I've not setup this server to be enrolled in a batch scheduler for resources
reservation.
My need is that unused Xvnc sessions (no keyboard/mouse input for may be 12h or
more) lead to ending the session automaticaly.

In that case MaxIdleTime should do exactly what you want. Just start
things like this:

vncserver -MaxIdleTime=43200

Then it will terminate by itself if there has been no user input for 12
hours.

Hi Pierre,

I'm back with this problem. I've tested this -MaxIdleTime when launching
vncserver. It closes the session but it leaves som lock files on the server. So
it is difficult to use it.
Moreover, I've figured out that user sessions can be very long on this server
and that it's not such a good idea to set this limitation.

I think a better idea is to implement a cron checking vncserver sessions and
sending a daily mail to users launching more than one server or when servers are
runing for a long time.

Thanks again for your help and advices.
