Figure 1 - Enter the hostname in the configuration windowThis document makes a few assumptions. Pieces of information marked like <this> are meant to be replaced with your specific information. For example: you would replace <HOSTNAME> with the appropriate host name depending on which host you have been assigned to use. The same goes for <USERNAME> and <VNC Session Number>.
The first step is to launch PuTTY. The PuTTY Configuration will open. Enter <HOSTNAME> in the "Hostname (or IP Address)" field. Also, select the "SSH" radio button. See figure 1.

Your VNC session should be two digits for this purpose. As we see in figure 3: if your VNC session number is 1 you would enter 5901 for both Local and Remote port.
When you have finished: click the "Ok" button. The new session window will update to reflect your changes. It should appear similar to figure 6.

Click the "Ok" button to complete the addition of the new session. To use the session you have created: double-click the session name. Authenticate as usual.
The last step is to start your VNC client. When prompted for hostname: use localhost:<VNC Session Number> (see figure 6)rather than <HOSTNAME>:<VNC Session Number>.
