Steve,
I observed ports 8875, & 1456, but I believe Napster has the ability to
use port 80, so port blocking won't help. We're doing a simple IP block
here, at the router. That will stop most users. There's a proxy function
within Napster, so there may be a small amount of people who will
Well... I ran Napster through Sniffer Pro. I logged on, searched for a song,
and then began a download. Here were my findings. The source port is

the source port switches to that of the machine that you are d

You'll need to block the servers themselves.

Another way of blocking napster is to deny any traffic destined for the
napster.com domain (208.184.216.230) I found that even by blocking those
ports napster was able to get out on other well known ports..
Hope that helps

RE: NapsterNapster uses whatever port it can find that will work. It scans
for a working port during installation. So blocking just one or two ports
will probably do no good. Most any user knowledgable enough to download,

I found my documentation and of course my memory had failed me. The ports
for napster are ,6699,,9009. I think blocking these will disable

I think the key is to allow outbound packets to the Napster servers and
other PCs on the Internet, but not allowing external PCs to establish a
connection to your users' PCs. Find out the ports that a PC running Napster
is listening on, and then block those at the FW. A PIX should do this by

Good luck.

Suggestions:
1. Contact Napster re:development tool, though I think that it is irrelevent
(development tools are a personal preference, any number of tools could get
you there with the goal clearly defined)
2. Do a few sniffer traces of the application in action in a test lab
environment. Yo
go download openNap and look at the source-code, that should pretty much
explain 99% of your questions.
