===== AFS Setup on Linux PCs =====

You may install a SLC6 form CERN (linuxsoft.cern.ch/cern/slc6X) and activate  the CERN features in the setup, which include also AFS software.

You need a valid CERN account.


Step by step procedure:

  * install the AFS software

      yum install \
        openafs \
        openafs-client

  * create a short and clean cellserv config

  cp /usr/vice/etc/CellServDB /usr/vice/etc/CellServDB.original

  > cern.ch                   #European Laboratory for Particle Physics,
  137.138.128.148             #afsdb1.cern.ch
  137.138.246.50              #afsdb3.cern.ch
  137.138.246.51              #afsdb2.cern.ch

  * set default cell to cern

  echo "cern.ch" > /usr/vice/etc/ThisCell

  * make sure kerberos is configured

  /etc/krb5.conf should contain

[realms]
CERN.CH = {
        kdc = cerndc.cern.ch
        default_domain = cern.ch
}

[domain_realm]
.cern.ch = CERN.CH



  * verify kerberos with your username at CERN and get ticket

  kinit thoffman@CERN.CH

  * as SLC6 (cern specific openafs package) fix /etc/sysconfig/afs      

  ENABLE_AFSDB=on
  ENABLE_DYNROOT=on
  CACHESIZE=100000


  * start afs

  service afs start

  ls /afs/cern.ch/

  * finally add to boot

  chkconfig --add afs
