Hello,
I am unable to create the connection on Paraview on a remote machine. The error is the following:
"
Error: in /opt/glr/paraview/paraview-ci/build/superbuild/paraview/src/VTK/Common/System/vtkClientSocket.cxx,line 51vtkClientSocket (0x6000001ebscb00):Failed to connect to server localhost:11111
"
Here is the description of the steps that I followed:
-
Connect to the remote machine, allocate a node, verify that the node is running using “squeue”, then ssh to that node.
-
Setup a tunnel between my computer and that node using:
ssh -N -L 11111:nodename:11111 email_adresse_of_the_remote_machine -
Verify that the tunnel is running:
local_machine> ps aux | grep ssh -
Go back to the remote machine and type:
/path_to_paraview/paraview/bin/mpiexec -n 20 /path_to_paraview/paraview/bin/pvserver
It returns:
"waiting for client…
Connection URL: cs//node_name:11111
Accepting connection(s): node_name:11111
"
- I open the same version of Paraview than the one that I have installed on the remote machine, which is 5.10.1
File > Connect > Add Server >
Name: add name
Server Type: Client /Server
Host: localhost
Port: 11111
Save > Connect
After 1min, it gave me the following error:
Error: in /opt/glr/paraview/paraview-ci/build/superbuild/paraview/src/VTK/Common/System/vtkClientSocket.cxx,line 51vtkClientSocket (0x6000001ebscb00):Failed to connect to server localhost:11111
I just want to mention that I also tried working with Paraview-5.9.1 both on remote machine and local machine, and I did had the same error.
I also tried different port 11511, 11611, instead of 11111, it does not help!
Another extra information, when I uninstall paraview and reinstall it again, it does keep in memory the connection that I tried before. I am wondering if there is something wrong with my setup!
PS: I also tried different remote machines, and still always the same problem.
Please feel free to share any suggestions that could be helpful!
I do appreciate your help!
Thank you,
Best,
