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
