VNC interactive sessions

The following command allows you to access the vizualisation service frontal node :

$ ssh <user>

The « vizalloc » command allows only one session at a time. The active sessions can be listed by the command «  vizqueue ».  To terminate a session, please type the command «  vizcancel ».

By default, a session will last 30 min and the maximum duration can not exceed 6 hours.

The following command will open a session if the resource is available :

$ vizalloc -m vnc

In such a case, the allocated node name is shown as follows :
