There is vnc-server-version.rpm on your installation cd.
Navigate to a directory when it resides and execute
rpm -ivh vnc-server-.rpm

of course you can complit the line with tab after vnc-server....

Yes, only vnc client is installed by default. You have it in the internet tools.
You can download from vnc site installs for the server either.

Hello Fadia,

you can get the original VNC from

http://www.realvnc.com/

It seems a pretty good intro how to setup VNC can be found at

Hi all

Thanks to you all , but i want to know how to instal the VNC from the CD and which on of them .

Re: VNC

Alexander Chuzhoy — Thu, 11 Mar 2004 04:51:09 GMT

mount the third (3) installation cd.

mount /mnt/cdrom

then issue this command
rpm -Uvh /mnt/cdrom/RedHat/RPMS/vnc-server-.rpm

where version is the version or of the package.It's simpler to press after vnc-server

on linux issue this command

vncserver
it'll prompt you for password

specify it (new one for clients)

then issue this command
vncserver :1

after that on windows machine start the vncviewer and
type in the window
Linux's IP:1

it'll prompt for a password , enter the same as you gave in the linux

Best regards

alexendra is right but lemme correct few things :

FOR LINUX
##################
[root]# vncpasswd
Password:
Verify:
[root]# vncserver

New 'X' desktop is hostname:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/hostname:1.log

##### its showing vnc is started on :1

now vncserver is started on ur linux
u can verify this by nmap -sS

NOW ON WINDOWS
- install VNC
- start>program> vnc > vncviewer
- it will show u a windows ..put IP of linux machine(eg. 192.168.0.1:1) , push ok and type password...there ya go..

You could also use a browser to connect to your vncserver.

http://hostname:580x

where x=the number of the display created when you started the vncserver.

Re: VNC

Peeyush — Fri, 12 Mar 2004 17:47:39 GMT

i bet it will work
http://hostname:580x
if u have "enable java enable"

Re: VNC

Fadia Almarei — Sat, 13 Mar 2004 05:29:04 GMT

but please i want to know what is the mean of the number 580

Re: VNC

Mark Grant — Sat, 13 Mar 2004 05:50:59 GMT

THe 580x is the port number that the software is ussing to communicate.

Can I just go back to your original question a moment and tell you that you don't need VNC to open your linux server from your PC. The linux GUI is "network aware" and it doesn't really care where your actual screen is. All you need, is to be running an X server on your PC. There are lots of these available for Windows. Then, all you need to do is tell your PC software where your linux box is and, in theory, your Linux GUI login will appear on your PC instead of on it's own console.

And everybody keeps saying how they don't like X!!!

if i want the windows console to work as a terminal for the linux server (like using X-manager in the HP servers system),is the VNC provide this utility or is it just as a pcanywhere , and if is it used as a pcanywhere what is the security hole in it and how can i protect my servers from these holes. Regards, fadia

Mark Grant — Tue, 16 Mar 2004 04:36:59 GMT

It is the same as PC anywhere.

This is why I'd suggest you look at something like Exceed or Reflections which will allow your PC to be a screen on the linux box and the performance will be almost the same as if you were on the linux box.

you can protect your vnc-server from unwanted connection configuring the iptables firewall on the server machine and/or you network firewall (protect the port 590x).
If you want to protect the communication between your clients and the server (the vnc protocol isn't crypted) you can run the vnc sessions through a secure ssh-tunnel. This is quite easy if the client machine is a linux box, but I don't know what to do with a Windows machine. I remember that the vnc documentation explains how to do this.
