Recording Industry Association of America (RIAA) is going after Universities for allowing the students to use p2p (kazaa) application to illegally transfer music and videos of artists they represent. At the moment there two schools that have been hit with a lawsuit. The only ways I know to block kazaa are: - Cisco's Protocol Filtering software which runs on their 7000 series routers. $$$$$ - PacketTear which cost around $12,000 dollars - Iptables- Costing only the pc. Discussions on various message boards regarding blocking kazaa has helped me block kazaa at the university I currently work at an save the department the headache the going through a lawsuit. Before blocking kazaa we received at least 3-5 e-mail from riaa and mediaforce starting XXX.XXX.XXX.XXX IP has be illegal sharing copyrighted media. These discussions have helped me and I am sure it has helped other network admin's that faced similar situation. -----Original Message----- From: Bob Keyes [mailto:bob@xxxxxxxxxxxx] Sent: Sunday, May 25, 2003 10:26 PM Cc: netfilter@xxxxxxxxxxxxxxxxxxx Subject: RE: how to filter kazaa All this talk of blocking kazaa seems a bit crazy to me. Don't you think that someone from Kazaa is reading this list? You certainly know they could. Each time you find a way to block kazaa they can work around your blocking. Instead of the arms race, how about a truce? How about detecting Kazaa packets and marking them as 'high throughput', and then using a bandwidth management algorithm to keep kazaa users happy without making the internet unusable for the rest of us. If you are unlucky enough to have to pay by bytes transferred, then I might suggest that you budget usage. I am sure that the average office worker doesn't use more than 300mb of Internet bandwidth a day, which I voracious p2p user certainly would.
