[Paraview] server configuration with two factor authentication?

[Vanmoer, Mark W]

This great, thanks for sharing, guys. Using xterm would have never occurred to me.

Are you setting the pvserver –client-host somehow? My old pvsc from Forge sent over the client’s hostname to the script. I tried that on Blue Waters and it works, but do I not need to actually do that? Also, are either of you setting –server-port in the launch script?

I liked this bit too as the windows version 'xterm -e ssh &'.

<Command exec="cmd.exe" delay="10">
<Arguments>
<Argument value="/C"/>
<Argument value="start"/>
<Argument value="cmd.exe"/>
<Argument value="/C"/>
<Argument value="$SSH_EXEquot;/>

Since windows isn't my first language, that took more hunting than I'ld like to admit. :)

Howdy Mark,

Adding to what Burlen said.

You can grab pvsc examples for ORNL, ANL and NERSC via
paraview->File->Connect… Fetch servers.
//File->Conenct…FetchServers->Edit Sources replace with pvsc http://www.paraview.org/files/pvscWindows Kitware Inc. on windows.
Mac requires XQuartz, windows requires putty.

Let me know when you get it working, with your permission I'ld love to add NCSA (and everywhere else) there so that users get it by default.

Hi Mark,

This works without anything special if you launch in an xterm. We did this at NICS which requires both ssh authentication and rsa secure id token. Here is an example<https://github.com/burlen/pvserver-configs/blob/master/pvsc/edison-unix.pvsc>

Hi, is there a way to set up the server XML so that it works with two factor authentication, as in a token generator? This is for the Blue Waters machine at NCSA. What I mean is, something like how VisIt acts, which when doing the connection will prompt for the password and token.

In the past, on machines without two factor auth, I’ve used

http://www.paraview.org/Wiki/ParaView:Server_Configuration#Case_Eleven:_Launch_pvserver_on_a_cluster_using_PBS_-_use_reverse_connection_to_client

but that requires having ssh keys set up.

Thanks,
Mark
