Using a single computer is not enough today, we are in need to use one more of it for testing even for a small modification we make to. Hence virtualization plays a vital role.

In the world of virtualization you may come / came across VNC (Virtual Network Computing). For more info google “VNC”

I am going to show some simple steps to be followed while configuring VNC for debian desktop.

Installation of VNC server is like cutting piece of cake

$ sudo apt-get install vnc4server

You can choose a geometry for viewing,

$ vnc4server -geometry 1024x768 -depth 24

This will prompt us to set a password and will verify once.


Your password will be available at ~/.vnc/passwd


To start a new server that runs on your machine

$ vnc4server 
New 'boss:1 (cot)' desktop is boss:1

Starting applications specified in /home/cot/.vnc/xstartup

Log file is /home/cot/.vnc/boss:1.log

It tells that newer server has been started with respective details for tracing.

To Kill the process (stop VNC server)

$ vnc4server -kill :1

Killing Xvnc4 process ID 16592 

To access remote machine (server) you need to know HOSTNAME of server(machine)

On remote machine enter the below command

$ xvnc4viewer boss:1

After issuing password,

 TXImage: Using default colormap and visual, TrueColor, depth 24.
 CConn: Using pixel format depth 6 (8bpp) rgb222
 CConn: Using ZRLE encoding

A new window will open up by holding the terminal of server (machine), you can’t access any GUI, but it is rather very much helpful for creating, running, debugging new applications.
