public class MulticastChat
extends Object

Simple chat application based on UDP multicast. Requires JDK 1.7+ When you run MulticastChat application, the first thing you might want to know is network interfaces' names available on your system (command #6), so type:

'$ 6'

and press enter to see the interfaces and check if they support multicasting. On my system I see:

 "
 $6
 wlan0 support-multicast=true
 eth0 support-multicast=true
 lo support-multicast=false
 "
 

which means I can use wlan0 and eth0 interfaces to test multicasting. So now I have to join the multicasting group

 "
 $2 228.5.6.7 eth0
 "
 

The output would be like:

 "
 Tue Sep 11 16:09:42 CEST 2012 /10.163.25.1:8888: joined the group /228.5.6.7
 "
 

Run MulticastChat application on different machine (it's better to use local network, cause multicasting might be blocked by routers), run the same/similar commands, so both clients join the same multicast group. To send message to the multicast group use the command like:

 "
 $1 228.5.6.7 hello
 "
