Connecting to a VNC Server through a SSH Tunnel

For security and privacy, VNC connection should be done through a SSH tunnel. Here, I am using Putty to set up a SSH Tunnel. First, type in the host name:


Putty_Setup_1003

Next, type in the user name:


Putty_Setup_1010

Check the following options. Also, move Blowfish up for speed:


Putty_Setup_1018

Set up a SSH tunnel. The Source port will be the local port through which the VNC viewer will connect. The destination port is the remote port whereby the VNC server listens. Click Add button:


Putty_Setup_1027

Save the Putty session.


Putty_Setup_1034

Now that you set up a SSH tunnel, you can use a VNC viewer like TightVNC to connect through the SSH tunnel to the remote VNC server. For example, specify localhost::5900 as the server host to TightVNC.
