[Paraview] Connect GUI to pvserver on Jaguar

[Stéphane Backaert]

Dear all,

I am trying to connect my GUI to a pvserver running on compute nodes on the Cray Jaguar.
I connect to a login node with a remote port forwrding: ssh -R 11111:localhost:11111 jaguarpf-ext3, where jaguarpf-ext3 is the name of a particular login node.
Then, I launch the pvserver with the option -rc --client-host= jaguarpf_ext3 but that does not work:
---------------------------------------------------------------------
ERROR: In /tmp/proj/ard013/pv_compil/ParaView-icarus-3.14.1/VTK/Common/vtkSocket.cxx, line 430
vtkClientSocket (0xe0aa50): Unknown host: jaguarpf-ext3

ERROR: In /tmp/proj/ard013/pv_compil/ParaView-icarus-3.14.1/VTK/Common/vtkClientSocket.cxx, line 53
vtkClientSocket (0xe0aa50): Failed to connect to server jaguarpf-ext3:11111
---------------------------------------------------------------------


There are two interfaces on jaguarpf-ext3: I identified which is for the outside and I suppose that the other one is for the internal cray network (both ethernet if)
Thus, I changed the options to -rc --client-host=172.30.215.69, but still not work, even if the message is slightly different.

I tried with the other interface. No more success...

Does anyone know what kind of port forwarding I must used to go through the login node on Jaguar?
Should I create a "tunnel" between" the two interfaces? How?

Best regards,
