The base port for VNC is 5900, add your display number :1 (that can be found in the above code segment) and we get 5901.

After running the paraview-vnc the GUI you will need to set up tunnel. The steps on how to do this will are shown below for the PuTTY SSH client and Linux/Mac Terminals.

Open PuTTY In addition to your standard connection PuTTY settings you will need to set up the tunnel settings. The image below shows you how this in done in PuTTY. The tunnel setting are found under the Category Connection –> SSH –> Tunnels

After you add this setting to your session you can save them or just open the session. You will have to leave this session open and open a VNC Client software to start the ParaView GUI on your system.

Open a new terminal session on your local machine. Set up a SSH Tunnel using the below ssh command. The base port for VNC is 5900, add your display number :1 and we get 5901.

$ ssh -L 5901:localhost:5901 mkyle@farber.hpc.udel.edu

With that SSH tunnel active, my MacBook port 5901 is logically mirroring port 5901 on farber. Now you can open a VNC client on your local machine that views the Paraview VNC display (e.g. command-K in the Finder, use URL "vnc://localhost:5901").
