Remote Desktop Connection via Putty SSH Tunnel

This helpsheet will show you how to use the PuTTY SSH client to setup an SSH tunnel to allow you to connect to your Windows Desktop on the Kettering University network via Remote Desktop Connection.

Note: This requires that you have and know both your Windows Domain login and password and your Unix/Nova login and password.

1. Start “putty.exe” downloaded from For more information about Putty please see

I suggest saving putty.exe to the Desktop or some folder that you will remember which is easy to get to. There is no install process for putty.exe, you just download it and run it from wherever you saved it.

When you first start putty, go to the “Session” in the Category tree and in the “Host Name (or IP address)” box type

2. Click to expand the Category tree to get to the “Tunnels” section (Connection->SSH->Tunnels). For “Source port” put “3400” for “Destination” type the name of your machine and then a colon and the port number 3389, example “” and Click “Add”.

Note: The use of port 3400 is arbitrary and could probably be any port above 1024.

3. You should now see something like the picture below with “L3400” in the “Forwarded ports” box.

4. Click back on the “Session” category and type something meaningful in for “Saved Sessions” such as “RemoteDesktop”. Click “Save” and then click “Open”.

Note:When you run putty again you will be able to to skip most of the steps above by just selecting the “RemoteDesktop” Saved Session, clicking “Load” and then “Open”.

5. A terminal window should pop up prompting you to “login as”, this is your Unix/Nova login and password. When you press enter you will be promted to enter you Unix/Nova password. This has created the tunnel that you can then use for the Remote Desktop connection.

6. Start Remote Desktop Connection, one way to get to this is to search for “remote desktop” through the Windows logo menu search field and the select “Remote Desktop Connection”.


7. In the Remote Desktop Connection for “Computer” type “localhost:3400”, you may also have to fillout the user name field with your Kettering domain user name “KETTERING\username” and then click “Connect” and you should then have your Remote Desktop Session.

Note: You may receive a warning message but you can safely ignore this.

8. When finished with your Remote Desktop Session, type “exit” in the terminal window to close the tunnel.

Note: Make sure that you have logged out or disconnected from your remote desktop session before terminating the tunnel, as terminating the tunnel will also terminate your remote desktop connection.
