The ruserok() function is called by Torque for every
submission, but it handles both /etc/hosts.equiv plus
..rhosts files.

Now in most clusters (where -u isn't being used) you
only need to configure /etc/hosts.equiv on the system
running pbs_server and you're done.

However, if you submit as a different user using -u
then /etc/hosts.equiv won't help and the trust
relationship has to be specified in the users .rhosts
file.

The other situation where that would be necessary is
where the user wants to submit from a different system
where his username is different.

cheers!
