There's a nifty new toy out there called 'napster' that's used for downloading/sharing MP3 files. It uses a WIDE variety of ports, and kind of like AOL IM it tries port after port after port until it finds one that'll connect. The default for it is 6699, but I've seen it use 6666 as well. This little toy is quite the bandwidth consumer. I've seen users peg t-1's for hours with it. (I've pegged t1's for hours with it being sucked into a pseudo mp3 addiction). I've requested a white paper from the program's creators describing it's port usage and protocols, but as of yet haven't gotten a response. The good news is, the program doesn't work for inbound connections to NAT'd client machines for (more or less) obvious reasons. But NAT'd clients can still connect to thousands of mp3 sharing computers out there and download gigs of mp3's. /*-----------------------------------*/ /* I live with FEAR every day. */ /* But, sometimes, she lets me RACE. */ /*-----------------------------------*/ KT Morgan Network Engineer Checkpoint Firewall-1 CCSA/CCSE Microsoft MCP Software Systems Group, Inc the compaq support website, crib notes version: "you cant do that."

All, I am looking at a bunch of machines that are running port 6666. I have validated that it is NOT IRC, but cannot figure out what is there. Is there a management protocol or something else that uses 6666? Phil
