Problems we have found before: 1) There is already a version of the ParaView client running. ps -ef 2)There aren't enough server nodes to run your job. You didn't ask for too many nodes, did you? Did you ask for the correct node? 3) The client machine cannot be seen from the server. From the server node, ping the client machine. Ping it's IP address. Ping it by name. 4) The client machine cannot be seen from the server. Start ParaView client in reverse connection mode, then try to telnet to this port. (Normally "telnet machine port"). It should just sit there. If you get a connection refused, client is not listening or port is blocked. 5) Once again, check that the ports aren't blocked. Try "netstat -a | egrep 11111"
There are just a few ideas...

I am trying to run pvserver on a single extra computer (so a total of mine + 1 = 2 machines) with the same architecture, same OS, same OpenMPI, same Paraview. I have been talking with the OpenMPI people and running "hello world" tests that are showing that everything is setup correctly and talking to each other with no problems. Both firewalls are off. Password-less ssh works both ways. pvserver is on both machine's PATH. I have compiled Paraview with PARAVIEW_USE_MPI set to ON in both cases. I have explicitly added the path to the openmpi libraries to LD_LIBRARY_PATH on both machines - that is, put the following in .bashrc on both machines: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib I am starting the server with a paraview command like this: mpirun -machinefile /home/doriad/Desktop/paraview_benchmarks/local_1+cloud_1.txt pvserver where local_1+cloud_1.txt is: 10.1.2.126 10.1.2.122 my machine is 126. I tell Paraview to connect to 10.1.2.126 on 11111. When I try to connect, I get the following in the paraview Output Messages. Any thoughts on what I have missed? Listen on port: 11111 Waiting for client... ERROR: In /home/doriad/src/ParaView3/Servers/Common/vtkServerConnection.cxx, line 67 vtkServerConnection (0x8d23600): Server Connection Closed!
