15.3.3. Connecting to VNC Server Using SSH

VNC is a clear text network protocol with no security against possible attacks on the communication. To make the communication secure, you can encrypt your server-client connection by using the -via option. This will create an SSH tunnel between the VNC server and the client.

The format of the command to encrypt a VNC server-client connection is as follows:

vncviewer -via user@host:display_number
