Hi everyone, I just compiled the OSMesa version of paraview 5.4.1 on Tianhe-2 supercomputer. My trouble is to connect the pvserver running on computing nodes while I am on login node with ssh tunnelling (-L).
Here is what I did My computer (win7 64 bit) ---ssh -L15801:localhost:15801 through VPN---> LN31 (login node, RHEL maybe, using slurm) > srun -n 24 pvserver -sp=15801 --mesa --use-offscreen-rendering --disable-xdisplay-test ---ssh -N -f -L15801:localhost:15801 though internal connection--> CNxxxx (computing node) And here is the error: ``` Waiting for client... Connection URL: cs://cn10687:15801 ERROR: In /HOME/pp569/soft/ParaView-v5.4.1/VTK/Common/System/vtkSocket.cxx, line 206 vtkServerSocket (0x20e9c20): Socket error in call to bind. Address already in use. ERROR: In /HOME/pp569/soft/ParaView-v5.4.1/ParaViewCore/ClientServerCore/Core/vtkTCPNetworkAccessManager.cxx, line 349 vtkTCPNetworkAccessManager (0x14ad080): Failed to set up server socket. Exiting... ``` It seems not working. I am pretty sure that the PC -- ssh -L through VPN --> LN works well. What happend in LN -- ssh -L --> CNxxx link? I have searched the internet for something, I found that LLNL did some work on it [ https://hpc.llnl.gov/data-vis/vis-software/paraview/running-paraview-in-client-server-mode ]. They used `ssh -R` to map from LN to CN, rather than `ssh -L` and run paraview in RC mode, does it make any sense? However, in Tianhe-2, the `ssh -R` is forbidden. So I cannot use this method.
