ADD ONE USER FOR VNCSERVER (For security purpose don't use root user)
[root@proxy2 ~]# useradd vncserver

GO TO VNCSERVER USER (ALSO YOU CAN CREATE PASSWORD FOR LOCAL USERLOGIN BY USING "PASSWD USERNAME" COMMAND)
[root@proxy2 ~]# su -l vncserver

CREATE VNC SERVER PASSWORD FOR CREATED USER (this password is must required for remote login)
[vncserver@proxy2 root]$ vncpasswd
Password:
Verify:
[vncserver@proxy2 root]$

ALLOW CREATED USER TO VNCSERVER (Uncomment last 2 lines & give user session , like 1st user '1:myuser')
[root@proxy2 ~]# cd /etc/sysconfig/
[root@proxy2 sysconfig]# ls -ltr |grep vncser
-rw-r--r-- 1 root root   847 Jan 15 2007 vncservers
[root@proxy2 sysconfig]# cp vncservers vncservers.org

[root@proxy2 sysconfig]# vi vncservers
# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see
# .
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-nohttpd" to prevent web-based VNC clients connecting.
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel. See the "-via" option in the
# `man vncviewer' manual page.
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
VNCSERVERS="1:vncserver" ------------------------------------------------------> ADD CREATED USER HERE
VNCSERVERARGS[1]="-geometry 1600x1200" ----------------------------------------> GIVE REQUIRED RESULATION TO VIEW
