 +==== About the network cables ====
 +- 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.
