I'm still having a couple of issues...

If I connect with "startup type: manual" after starting pvserver on
the remote machine, everything is working fine. If I connect with
"startup type: command" and put "pvserver" as the command, it says

"The startup command failed to start ... check your PATH and file
permissions " - even though I assured pvserver is on my path on the
remote machine ('which pvserver' returns the correct path')

If I put "/home/doriad/bin/ParaView3/bin/pvserver" as the command, it says

ERROR: In /home/doriad/src/ParaView3/VTK/Common/vtkClientSocket.cxx, line 54
vtkClientSocket (0xe7009f0): Failed to connect to server
sgi6110.ecse.rpi.edu:11111

ERROR: In /home/doriad/src/ParaView3/Servers/Common/vtkProcessModuleConnectionManager.cxx,
line 289
vtkProcessModuleConnectionManager (0xe096790): Connect timeout.

I can password-less ssh (using rsa keys) both ways.

Does anyone know what would cause this behavior?

Thanks,

David
