Before traveling and always when your notebook is attached to the network:

• login with your acoount with an empty password (possible only in front of the notebook). If this is not possible use the guest account the first time.
• Connect to the network by running the command
  • using cable based interface with: lan start using the wireless interface: wlan start
• Each time a network interface is started, an automated check for avalaible updates is performed in the background. There's nothing to be done but accepting the updates offered.
  • manually: nbctl sync
  • without DESY synchronization: nbctl yum

• if you notice suspicious files or activities please contact uco-zn@desy.de

Recommendations:

• Lock the screen with a special xlock-password for which you will be asked the first time
• Arrange for secure password-less access to the notebook with ssh key authentication
