Hi Mark,
Yes to both. The way this could work on a simple cluster is: from the
user's system which is assumed to be remote, the pvsc creates an ssh
tunnel inside the xterm and calls the launch script on the compute
system login node. the launch script submits the batch job. pvserver,
when run in the batch script, connects back to the ssh tunnel on the
login node. "client host" is the login node host name. "server port" is
specified by the user in the pvsc.
There's a slight complication with some Cray systems that means we need
to involve a special node called the "mom" node in the tunnel.
This will be clear if you see a complete example, for instance the
following 3 scripts are used with NERSC's Cray Edison:pvsc
<https://github.com/burlen/pvserver-configs/blob/master/pvsc/edison-unix.pvsc>,
launch script
<https://github.com/burlen/pvserver-configs/blob/master/servers/edison/4.3.1/start_pvserver.sh>,
batch script
<https://github.com/burlen/pvserver-configs/blob/master/servers/edison/4.3.1/start_pvserver.qsub>.

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

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

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
