Multicast test bed

I'm trying to learn something about multicasting. I've read up on
IGMP, multicast addressing, etc. but I'd like to _see_ it work. I
know *nothing* about multicast applications.

I'd likle to set up a little test bed with a simple, low-volume,
multicast server and a client or two all on my desk, connected to one
switch with some snooping software. I have access to Linux and XP.
Can someone recommend an application that I can use for my
experimentation?

Isn't NTP a multicast application? Would it make sense for me to set
my Linux box up as an NTP server and set my XP system up as a client?
Is going over to CompUSA and buying a webcam a reasonable approach?
What would I use as a remote client?

TIA.

Chris

You can use Iperf and Ethereal to generate multicast traffic and capture it.

http://www.ethereal.com <---Captures the traffic
http://dast.nlanr.net/Projects/Iperf/ <--Generates the traffic

Tons of mcast tutorials available on the net. Just Google for IGMP or IP
multicast.
