I doubt you can ssh from the client node to 'host3.cern.ch' (FQDN is
important). This might be due to the fact that your 'ssh_known_hosts'
file does not contain an entry for the FQDN.
You probably also want to examine the use of the '$usecp' flag in
pbs_mom's config file in case your homedirectories are mounted with NFS
throughout the whole cluster.
