[root@dhcppc1 ~]# su -jackiebui

Password:******
verify:******
[jackiebui@dhcppc1 ~]# ls .vnc/

5. Edit VNC Configuration File:

[root@dhcppc1 ~]# vi /etc/sysconfig/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 this URL:
# http://kbase.redhat.com/faq/docs/DOC-7028

# Use “-nolisten tcp” to prevent X connections to your VNC server via TCP.

# 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:jackiebui”
VNCSERVERARGS[2]=”-geometry 800×600 -nolisten tcp -localhost”

6. Start VNC Server:

[root@dhcppc1 ~]# vncserver
[root@dhcppc1 ~]# chkconfig vncserver on

8. Type your VNC password:
