Client Server Mode - unsupported

MIT Engaging cluster ParaView client server mode documentation.

Client server mode appears broken. When setting up SSH tunnel, as shown, you get this on the client side:

Connection failed during handshake.
 returns different values on the two connecting processes
 (Current value: 100).

At least one site does not support client-server anymore (due to issues like this one from the RWTH HPC IT Center help page).

PvPython and PvBatch

PvPython and PvBatch work and are available. Suggest reviewing the ParaView PvPython and PvBatch wiki and using only the PvBatch part of ParaView:

[arnoldg@dt-login02 ~]$ cd paraview_pvbatch/
[arnoldg@dt-login02 paraview_pvbatch]$ vi  # sample from URL above for pvpython
[arnoldg@dt-login02 paraview_pvbatch]$ pvpython
[arnoldg@dt-login02 paraview_pvbatch]$ ls  greenSphereScreenshot.png
