Also be aware that there is a bug in ParaView, where if the server
startup command doesn't return for some reason, ssh turns into an orphan
process and will not relinquish the ports it used, preventing any
further use of those ports.
http://www.paraview.org/Bug/view.php?id=10283
I did submit a patch to fix it but it has yet to be applied.

Your command isn't quite right, specifically how you are trying to
specify the compute node.
Take a look at the section here,
http://paraview.org/Wiki/Reverse_connection_and_port_forwarding#Reverse_Connection_Over_an_ssh_Tunnel
It's a little closer to your situation.

Hi,
Thanks for the reply..I did look at the wiki and tried the following..
I set up a server/client reverse connection and trired to connect..
but i coudn't.. this was the command that i gave for the server..
olivegarden is the hostname of my laptop.
ssh -i /home/dagarshali/.ssh/id_rsa [email protected]
<mailto:[email protected]> node083 pvserver
--reverse-connection --server-port=11111 --client-host=olivegarden
here node083 is the node where the pvserver was launched...
so wasn't sure how to give that info in this command.. or am i doing
something wrong.. when you say that start the cient, am i just
creating a server/client and connect in manual mode..?
Regards,
Vishwa

Currently you are not launching the server in reverse
connection mode. To launch the server in reverse connection
mode, you need to give it the arguments -rc (or
--reverse-connection) and --client-host=/laptop.hostname.com/
<http://laptop.hostname.com/>. When given these arguments,
the server will immediately try to make a connection to
/laptop.hostname.com/ <http://laptop.hostname.com/>. Thus,
you first need to have your client running and waiting for the
server to connect. After getting things set up, you should
eventually try to set up your client to automatically start
the server with an ssh call and then wait for the server to
connect back.

Hi,
I would to visualize the data that is being computed on a
hpc by
using pvserver and paraview.
i have come across a many documents saying how to connect
and the
one what i thought might be appropriate in my case would to
be to
run pvserver on the hpc and then connect to it usind
server/client
reverse connection from my desktop..
here is the procedure that i use to connect to the hpc to
submit job.
i log in to the head node via ssh [email protected]
i then submit my job using the the following script via
qsub myscript
*#PBS
-lmem=2Gb,nodes=1:ppn=4,cput=24:00:00,walltime=24:00:00
cd $PBS_O_WORKDIR
cat ${PBS_NODEFILE} > node1
mpirun --machinefile ${PBS_NODEFILE} -np 4 pvserver
--use-offscreen-rendering -\
-server-port=11111 >log1
*
in the node1 file, i get say node083 (and it is repeated 4
times)
I am not sure how to connect to this node say by running
paraview
from my laptop to visualize that.
Any help would be greatly appreciated..
Regards,
vishwa
