[Paraview] How to run ParaView on a cluster without X server

[Randall Hand]

oh, sorry.. I misunderstood your problem..

You're saying that your backend nodes have no external visibility? (eg, they
can't see the client).  We have that same situation here.  There's a few
options that I know of, other folks here may know more:
1) Make sure that Process 0 of your pvserver is running on the Head-Node.
Only Process-0 needs to communicate with the client.
2) Talk to your admins & get NAT setup on the cluster.

In short, you need to be able to get traffic between Process 0 and your
client.. If you can't access the nodes, and they can't access you, then
you're hosed.
