VNC (Virtual Network Connection) allows you to run graphically intensive applications directly on a remote machine rather than trying to forward an Xsession back to your local host. VNC clients are available for Mac, Windows, and Linux. CGD is using TigerVNC for both the server and clients.

For Apple Mac users, the instllation kit is in Self Service.

Systems available for VNC


Using VNC

On the remote host

Once you've installed a VNC client on your local host, connect to one of our general use servers. For this example we're using

  1. SSH to the server

    ssh -X -Y
  2. Launch the VNC server

  3. Set your vncpasswd if prompted. Make note of the new desktop, it will be something like "" Leave your ssh session running, you'll need it when you're finished.

VNC Step 1

On the local host

Start TigerVNC on your local system and connect to the server.

Enter the full hostname, a colon, and the port number as depicted in item 4 of the image above.

In this case, but your case may vary depending on the server used in item 1 of the image above.

VNC Step 2

Enter your VNC password

Now you have a remote graphical connection to thorodin. Run your application such as Matlab or IDL. The virtual desktop can be resized by dragging the corners.

VNC sessions are killed daily at 2:00am local time. If you need to runs jobs longer, create them as usual with 'screen' or 'nohup'.
