How to configure VNC Server

1) Login as root on Redhat Linux Server
2) First we need to check the VNC packages installation.
rpm –qa | grep vnc
$ rpm –qa | grep vnc
Vnc-server-4.0-8.1
Vnc-4.0-8.1
The vnc package is installed as shown above. If not then install vnc package.
3) To start the VNC on system boot time,
# chkconfig –level 345 vncserver on
4) Uncomment the following lines and add all the VNC sessions required to start at the startup time in the /etc/sysconfig/vncservers file.
VNCSERVERS=”1:root 2:oracle”
VNCSERVERARGS[1]=”-geometry 800×600”
# vi /etc/sysconfig/vncservers
5) Login as the user for whom you want to configure VNC or use this command to login.
# su – oracle
6) Run the vncserver command to configure the VNC-based X session.’
Note: The vncserver :1 will create the $HOME/.vnc> directory for the user and will ask for a VNC password. This password will be requested by the VNC viewer program when connecting from a remote machine.
7) If the user wants to change the VNC password, in future the following command will be used:
$ vncpasswd
Password:
Verify:
$ HOME
Cd .vnc
Vi xstartup
