Using the GUI via X-Forwarding ¶Įven the developers, KitWare, say that X-forwarding is not supported at all by ParaView, as it The recommendation, though, is to use VPN, which makes this extra step Note that you then must instruct your local ParaView client to connect to host For theĮxample IP address from above, this could look like the ssh -f -N -L11111:172.24.140.229:11111 command opens the port 11111 locally and tunnels it via login1 to the pvserver running on Or, when coming via the ZIH login gateway ( ), use an SSH tunnel. You now areĬonnected to the pvserver running on a compute node at ZIH systems and can open files from itsĬonnecting to the compute nodes will only work when you are inside the TU Dresden campus network,īecause otherwise, the private networks 172.24.* will not be routed. Process terminal, and within ParaView's Pipeline Browser (instead of it saying builtin). The final step is to start ParaView locally on your own machine and add the connectionĪ successful connection is displayed by a client connected message displayed on the pvserver The previous SSH command requires that you have already set up your You first have to resolve the name to an IPĪddress on ZIH systems: Suffix the node name with -mn to get the management network (ethernet)Īddress, and pass it to a lookup-tool like host in another SSH session: Use this line as-is for connection with your client. However, since the node names of theĬluster are not present in the public domain name system (only cluster-internally), you cannot just This contains the node name which your job and server runs on. Once the resources are allocated, the pvserver is started in parallel and connection information If the default port 11111 is already in use, an alternative port can be specified via -sp=port.
