[Paraview] Error when starting ssh session on PV5.5

Fri Apr 13 11:31:49 EDT 2018

Hi Cory,

Indeed I’m using an SSH tunnel from my client to connect to the server, specifically with the following command:

```
ssh <user>@<remotehost> DISPLAY=:0.0 /path/to/mpiexec -np 4 /path/to/pvserver" --server-port=11111 --client-host=<clienthost> --force-offscreen-rendering
```

How would I start the pvserver remotely without SSH? Both client and remote are on the same VPN network.

Met vriendlijke groet,

Chris, are you using an SSH tunnel to connect the client to the server?

As a reference point, I was able to connect from a Windows client to a linux server using the binaries from paraview.org/download<https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fparaview.org%2Fdownload&data=02%7C01%7Cc.coutinho%40redstack.nl%7Cfd02b381c49b4dc2038908d5a152cd4d%7Ceea7d51815bf4e07834271208871a965%7C0%7C1%7C636592299370036781&sdata=Mpp3d5x99WLUssJx8Iak1GvELn1ztU9Q1zGJct%2F%2FJaw%3D&reserved=0> with no SSH tunnel.

Thanks,
Cory

Thanks for the reply to my questions David, that solves two out of the three.

I’m still curious about the SSH problem with 5.5, though. For now I’ll stick with 5.4.1

I have not seen the windows 5.5 no ssh problem yet so I can't comment.

Other replies:

 Specifically I tried both the ParaView
downloads with and without MPI, but neither solved the problem. Btw,
what's the difference between those two? I see only one option for Linux
(with MPI).

For linux and mac we can bundle MPI. For windows it is easier to depend upon the user to install microsoft's mpi (it is free and works well). However the mpi-enabled version relies on the availability of microsoft MPI, this we also publish an MPI free version.

Also a side question: On the client, ParaView doesn't keep multiple
servers.pvsc files for each version of `paraview` installed on the
client (in %APPDATA%\Roaming\ParaView\), although it does keep separate
.ini files.  Is this expected?

Yes.

hope that helps. Hopefully others can continue on the track of the ssh problem.
