• Check the host accessibility by ssh:

  $ ifconfig

  Note IP address of the eth1 interface, e.g. 192.168.56.101 From the host terminal

  $ ssh [email protected]

  Edit /etc/hosts. Add

  192.168.56.101 dirac.cern.ch dirac

• Follow instructions in /home/dirac/Tutorial/README file to prepare the host

Installation of the minimal DIRAC service

• Edit install_minimal.cfg configuration file

• Install minimal set of the DIRAC services with:

  $ ./install_site install_minimal.cfg

  Hint: Populate /opt/dirac/.installCache with files in /home/dirac/Externals
