You have to upgrade to the DV supported version (SL4). Please contact uco-zn@desy.de

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
