Enable VNC service in a Redhat Linux Machine

If we want to get the graphical user interface of a linux PC from remote machine, then we have to enable the VNC service on that linux machine. We can enable the vnc by following ways in Redhat linux machine:

1. Login to a particular linux machine with a remote login utility like putty.

1. Check the vnc service whether it is enabled or not with this command: vncserver.

1. If the vnc service is disabled then go to the sysconfig directory. #cd /etc/sysconfig and open the file vncservers with the command, vi vncservers.

Uncomment and edit the following lines as follows:
VNCSERVERS=”1:root”
VNCSERVERARGS[1]=”-geometry 800×600″


1. Set vnc password using #vncpasswd.
1. Go to directory #/root/.vnc/ and edit xstartup file using # vi xstartup as like just uncomment first two line.
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc


1. Stop ,run and restart vnc service using #service vncserver stop/start/restart
