How to build ParaView with multiserver support?

ParaView Support
1

I would like my client to be able to connect to multiple servers. I heard that ParaView has to be built with multiserver option to achieve it. Although I looked at the CMake options with ccmake in the ParaView superbuild, I cannot find which option enables the multiserver build. Could you help me finding it?

Its just a CLI option, --multi-servers

I started pvserver on one of the remote machines after logging in with

ssh -L 11111:localhost:11111 user@machine1

I started pvserver on the other remote machine after logging in with

ssh -L 11112:localhost:11111 user@machine2

I started the ParaView client with the --multi-servers flag and connected to machine2 with the configuration cs://localhost:11112. The connection is established. When I wanted to connect to machine1 with the config cs://localhost:11111, I get the following error on machine1:

channel 3: open failed: connect failed: Connection refused

and on the client:

Can you try without SSH tunelling in the mix ?

I can only access the remote machines via SSH, sorry.

6

you can run pvservers locally.

It works when the servers are launched locally.

Then its something wrong in the SSH server setup, not related to ParaView.
