VNC
Description
Virtual Network Computing
Through the use of software VNC, acronym for virtual network computing,
makes it possible to interact with a computer from any computer or mobile
device on the Internet. VNC software provides cross-platform support
allowing remote control between different types of computers. To use VNC
you must have a network TCP/IP connection, a VNC server and a VNC viewer to
connect to the computer running the VNC server.
System Requirements Any system with video support, vncserver installed
(comes standard with all Linux distributions), network connectivity and a
client machine (like a laptop or desktop workstation) with VNC Viewer
installed.
Hardware Requirements
On your server none
On your client it helps to have more ram for cache
Software Requirements
Linux OS
· ALL Distributions
Co-requisite Software
Make a script (example below) and name it xstartup
Installation and Operation Details
Estimated Duration
5 min
Installation Steps (show ALL commands used. e.g. even mount/unmount)
Step 1: Workstation Preparation
install vnc viewer on your local windows machine ie laptop or workstation
Step 2: Server Preparation
Create xstartup file on remote machine
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
if [ -r /etc/redhat-release ]
then
/usr/bin/gnome-session
exit 0
fi
if [ -r /etc/SuSE-release ]
then
startkde
exit 0
fi
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
exit 0
Step 3: Install Software
After you have loaded your os, set up the network on your remote machine,
and you have created your xstartup file fallow the commands below
mkdir /root/.vnc
cp xstartup /root/.vnc
service vncserver restart
· On your server type
vncserver :33
· The :33 sets it to port 33 this can set this to any port just
substitute you favorite # where 33 is.
· There can be multiple sessions open on a machine you just have to
open more ports by typing vncserver :<any number you want>
Step 4: Verify Installation
To verify from you work station open your vnc viewer type in your remote
system IP address with your port # fallowing (i.e. 9.44.64.106:33)
When prompted type in your password and hit enter the video from your
remote machine should come up on your client.

After doing the VNCSERVER am I supposed to logoff? If so how do I do it?
Also we are connecting from another session but all they see is a gray
screen.
Do I have to do anything to the xstartup file? It is pointing to an init
file. Thanks all.
Bob
Stay COOL ! Happy Summer !

Thanks for the tip, Kevin...the memory stick that is.
I have bought and downloaded the newest version of RealVNC for my
Linux box but haven't installed it yet. I was told by their tech
support that will allow me to attach to the server and view the
current session, instead of creating a new session on the server.
Can you verify this is true??
Thanks.
Liz
PS My condolences to all Londoners on your tragic losses...what a
shock that was to hear about it on the news as we drove to work. I
have an uncle, aunt and cousins living in Maidenhead...getting a
little too close to home.

Good Day All. I have been asked to install VNC first on my PC
and then the production server. I am a real Linux newbie. Can
someone point me to a good site to down load it from or is it
an RPM in Red Hat v9? Also is it part of RH E3? Thanks for any
help the group can give me.
Good, VNC is absolutely brilliant and a godsend for remote support.
We use tightvnc (www.tightvnc.com), the RPM just installed on ES3
and it works a charm. If you only want to use your pc as a client
then there's no install required. Just download vncviewer and run
it! Personally I have putty and vncviewer on a memory stick which
give me full access to the servers.
