Hi Pradeep,
vtkClientSocket (0x7fc9ae108cb0): Socket error in call to connect.
Permission denied.
Your connection is being blocked somewhere in between your compute node
and workstation. there are various configuration setting on either/both
client and server that could cause it. Fortunately we do not need to
change any of these settings , many of which require root access and
potentially open security vulnerabilities. Instead, you will use an ssh
tunnel and a server config (pvsc) tailored to your situation to automate
the process.
I'm attaching a minimal pvsc that illustrates how one might configure a
reverse connection to a server with graphics hardware. This pvsc is for
illustration only, don't use in a production setting! There are number
of liberties I've taken, for example I assume that X11 is already
running, and I use "xhost +"(very very bad) to enable pvserver to access
gpu's. Normally I would put all of the server side stuff in a shell
script. I didn't do that here to keep things simple for you. I hope you
can use this to understand how PV works.
1) I connect to the CentOS machine using "ssh -X machinename".
Don't do that. With -X forwarding you won't be taking advantage of your
cluster's graphics hardware.
Hope this helps

Doesn't look like your client machine can connect to the server

ping 83.shin.fluid.cse.nagoya-u.ac.jp
telnet 83.shin.fluid.cse.nagoya-u.ac.jp 11111

Hello,
I have installed Paraview 3.98 on my Desktop (Mac OSX 10.8) and a remote
machine running CentOS 5.4. The CentOS machine has rendering hardware so I
havent installed PV with OSMesa support.
I can login to the CentOS from my Mac using SSH and vice versa.
Here is how I am trying to connect:
1) I connect to the CentOS machine using "ssh -X machinename". When I start
the "pvserver" on the CentOS the output is:
-------------------------------------------------------------------
[pradeep@83 ~]$pvserver
Waiting for client...
Connection URL: cs://83.shin.fluid.cse.nagoya-u.ac.jp:11111
Accepting connection(s): 83.shin.fluid.cse.nagoya-u.ac.jp:11111
-------------------------------------------------------------------
2) Then I add this information in the paraview I am running on my Mac as
shown in the attached image file.
3) I click on connect.
I get the following error:
------------------------------------------------------------------------
ERROR: In /Users/pradeep/softwares/ParaView/VTK/Common/System/vtkSocket.cxx,
line 481
vtkClientSocket (0x7fc9ae108cb0): Socket error in call to connect.
Permission denied.
-----------------------------------------------------------------------
I dont have any expertise in networking and so I dont know much about
firewalls of my systems here nor do any my colleagues do.
Thanks in advance,
Pradeep
