Re: [Paraview] error when connecting to pvserver

2015-05-20 Thread Utkarsh Ayachit
The client and server processes both print out a message with the
handshake strings they compared with. Mind posting both of them?

Thanks

 Hi,

 I am trying to connect Paraview server (pvserver) to test the Paraview
 Catalyst example codes from GitHub account. So, i installed Paraview from
 source (under Centos 7.0) without any problem and then test code. The
 problem is that i am getting following error messages when i try to run
 the example,

 ERROR: In
 /opt/progs/paraview-4.3.1/src/ParaViewCore/ClientServerCore/Core/vtkTCPNetworkAccessManager.cxx,
 line 424
 vtkTCPNetworkAccessManager (0x1063f00):
 **
 Connection failed during handshake. This can happen for the following
 reasons:
  1. Connection dropped during the handshake.
  2. vtkSocketCommunicator::GetVersion() returns different values on the
 two connecting processes (Current value: 100).
  3. ParaView handshake strings are different on the two connecting
 processes (Current value: paraview.4.3).
 **

 In this case, both server and client are using same Paraview installation
 and i disabled both firewall and selinux to eliminate the possible error
 sources that might cause the problem. The server is also started using
 following command,

 [turuncu@epsilon-lnx CFullExample2]$ pvserver --server-port=2
 Waiting for client...
 Connection URL: cs://epsilon-lnx:2
 Accepting connection(s): epsilon-lnx:2

 and the client code is running as follows,

 [turuncu@epsilon-lnx CFullExample2]$ ./CFullExample2
 SampleScripts/feslicescript.py

 I enabled live visualization by setting it True and proper server address
 and the port in the Python coprocessor code. I also tried to connect
 server from another machine directly using Paraview and it is working. At
 this point, i just need help to find the problem.
 Best Regards,

2015-04-13 Thread Schlottke, Michael
Hi Utkarsh,

It is the same installed version that I use both for the client and the server. 
As you correctly pointed out, MPI is enabled.

However, I somewhat narrowed down the scope of the problem. Apparently, if I 
use X forwarding via ssh, everything works correctly. Only if I run the 
ParaView client from within a VNC session the observed problems occur. Any idea 
where I might look for a possible solution? Using ParaView via X forwarding is 
unbearably slow in my current setup…

Which vnc server are you using? Seems to me your VNC server is missing
some X extensions (or something like that). We do use VNC servers here
for running tests, so it's known to work.

Re: [Paraview] Error when connecting to pvserver (pv 4.3.1)

2015-04-13 Thread Schlottke, Michael
Thanks for the hint, this seems to resolve my issue: I use 
tightvnc-1.3.9-110.1.x86_64 on the machine where it does not work, but on a 
different machine (with tightvnc-1.3.10-14.2.1.x86_64 installed) it works.

Might not be just the vnc server version but maybe a related package, but it 
was definitely a fault with our site setup. Thanks for helping me to track this 
down!
