Once the SSH server is installed and active it is time to move to the other system. At the other system, log in to the remote system using the following command, which will establish the secure tunnel between the two systems:
ssh -L 5900:localhost:5900 hostname
In the above example, hostname is either the hostname or IP address of the remote system. Log in using your account and password. The secure connection is now established and it is time to launch vncviewer so that it uses the secure tunnel. Leaving the ssh session running in the other terminal window, launch another terminal and enter the following command:
The vncviewer session will prompt for a password if one is required, and then launch the VNC viewer providing secure access to your desktop environment.
