Leave Use VNC server as gateway unchecked.Enter the name of the login node under Host.Under Gateway (SSH server or UltraVNC repeater):.From within TurboVNC it is straightforward to make a tunneled connection: The Java TurboVNC Viewer, which is available on Windows, macOS and Linux, has builtin support for SSH tunneling. The native version is also scheduled to be deprecated starting with TurboVNC version 3. The native (Windows) version does not offer the builtin tunneling option. This section only applies to the Java version of the TurboVNC viewer. In the command prompt, navigate to the location where you saved plink.exe, use the command line you got when you started the server but use plink.exe instead of ssh as the command. Next, start a command prompt (Windows-button + r, type cmd, press enter). An alternative is to install TurboVNC and use its Java-based viewer, which comes with builtin SSH tunnelling, see below. At you can find the download link to plink.exe. Microsoft Windows does not have built-in SSH capabilities, the best option is to first download the Plink tool (which is part of the PuTTY software). The VNC viewer will then ask for your user/password to connect to the VNC server, after which the connection to the remote desktop will be complete. With the tunnel created we can now use a VNC viewer to connect to localhost:1, which is the local endpoint of the SSH tunnel (VNC display :1 will get translated into port 5901).
Leave the terminal window with the tunnel command open, as closing it will also close the SSH tunnel. In most cases TCP port 5901 needs to be tunneled, which corresponds to VNC display :1 (port 5902 would correspond to display :2, etc).Īfter executing the command above the SSH tunnel will have been set up and you will be logged into one of the login nodes. Workstation$ ssh -L 5901:r34n4:5901 uses the ssh command to set up an encrypted tunnel that forwards TCP port 5901 on your local machine to port 5901 on the GPU node r34n4 on Lisa, using the interactive visualization node as access point.
