VNC server on Linux

Setup VNC server on a Linux machine

Login with the user for which you want to allow remote desktop and enable vncserver startup from System ->Administration->Server Settings->Service configuration

Add the following lines to /etc/sysconfig/vncservers

VNCSERVERS="1:#username#”

VNCSERVERARGS[1]="-geometry 1024x768 -depth 16"

where #username# is the name of the user for which you want to allow remote desktop.

Start and stop VNC server to create the VNC startup file /home/ciuser/.vnc/xstartup

vncserver :1

vncserver -kill :1

The of /home/#username#/.vnc/xstartup must be as follows

#!/bin/sh

vncconfig -iconic &

# Uncomment the following two lines for normal desktop:

 unset SESSION_MANAGER

 exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid grey

xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

Copy & Paste the lines above into /home/#username#/.vnc/xstartup where #username# is the name of the user for which you want to allow remote desktop.

 vncserver uses the ports 5901 for display :1, 5902 for display :2, and so on.

The sessions are available on ports 5901 for “regular” VNC viewers (equivalent to VNC display 1) and on port 5801 for Web browsers. 

For example, in the browser you can access a machine with VNC server running:

http://machineName:5801 

which is equal to using a VNC desktop client, on this one you will use

machineName:5901
