VNC

The Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.

The recommended clients are TightVNC or TigerVNC (free, open source, available for almost any platform).

Create VNC Password

!!! note Local VNC password should be set before the first login. Do use a strong password.

[username@login2 ~]$ vncpasswd

Start Vncserver

!!! note To access VNC a local vncserver must be started first and also a tunnel using SSH port forwarding must be established.

See below for the details on SSH tunnels. In this example we use port 61.

You can find ports which are already occupied. Here you can see that ports " /usr/bin/Xvnc :79" and " /usr/bin/Xvnc :60" are occupied.
