[torqueusers] PBS and Globus gatekeeper node

Try adding the machine to /etc/hosts.equiv on the PBS server.  That helped
me even though I'm using ssh.  I was getting the same error.

NB: We've never tried this, no idea if it can work or not..

A few thoughts:

1) Is anything logged about rejection on the destination machine ?   Could
be that it's not permitted to queue jobs to that PBS server, or some DNS vs
local hostname issues ?

2) Does the following command work from your gatekeeper ?

 qstat -q @anothermachine.mydomain.com

3) Can you submit a test job to that remote system without using a routing
queue ?  For example:

 echo hostname | qsub -l walltime=0:1:0 -q queue at anothermachine.mydomain.com

This works here between machines (which suprised me!).

4) Do you see anything on the wire if you run a packet sniffer ?
