Set up a VNC server

vnc allows you to connect to a remote computer's display over the network. It consists of a client and a server. The client is the viewer, the server provides the display. You can also allow browsers to view the server's desktop.

server

for a web browser

To configure vnc so it can be viewed from a web browser:

Fedora 14

• install and start vncserver

yum install tigervnc-server-applet
vncserver -httpport 80

• install xterm as vncserver will by default try to start xterm. Install nmap to verify vncserver is listening on a network port.

yum install xterm nmap

• verify the server is listening on port 80

# nmap localhost

Starting Nmap 5.21 ( http://nmap.org ) at 2010-11-28 09:57 UTC
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000015s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
5901/tcp open  vnc-1
6001/tcp open  X11:1

• stop the firewall

/etc/init.d/iptables stop
chkconfig iptables off

• point your browser to your server
• you can log in, then you see the same content as when calling vncviewer
