+- Very often SISSA staff has to upgrade linux workstations due to SECURITY PROBLEMS. These operations are executed remotely, so all the linux workstations have to be connected to the network;\\
+- other users can have their files on your linux workstation local **/scratch** area and they could need to use them, so do not unplug the network cable or switch off your linux workstation.

-  * **inside its room** ... the frame of a workstation have to remain on a table or on another kind of furniture and NEVER NEAR TO A BLACKBOARD, because dust of the floor and chalk damage the hardware. For example, the fans will ruin and then make noise.\\

 ==== Why you have not to use other workstations without the authorization of the main authorized user ====
 Users are generally provided by one personal workstation in his/her office.
-If you wish to run (in "remote" mode using ssh not in "local" mode) your computations on a workstation of another user (your room-mate for example) you HAVE TO ASK him/her for permission before doing. You should not run more than one production job at a time on its and always run your executable at the lowest priority.
