Complete!
vi /etc/sysconfig/vncservers
remove everything and add:
# 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
# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.
# 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 800×600 -nolisten tcp -nohttpd -localhost”
VNCSERVERS=”3:oracle”
VNCSERVERARGS[3]=”-geometry 1024×768 -depth 16″
save the file
VNCSERVERS=”3:oracle” – means vncsession for user oracle and port 5903
so in vncviewer you would connect as:
my.host.com:5903
####
su – oracle
crate vncpasswd file:
vncpasswd
Password:
service vncserver start ( as root)
Now you can connect via vncviewer using: my.host.com:5903 and user oracle

  1. I want to set up a vncserver on a generic/clean Centos or RH type Linux. I am working within the AWS EC2 infrastructure but that should not matter I believe.To make this effort succeed there are some prerequisites we need to help us run the vnc session i.e., X Windows.I've installed all the usual packages, facilitated by yum, and followed every bit of advice I can find on the internet. I have tried all the advices and tips on the internet about installing fonts, creating links, renaming x,y and z to no avail. How can I get it to work? what if i want to sync servers with tiger vpn? http://www.bestvpnservice.com/tigervpn/
