Blocking Kazaa 2.0?

coder_ asks: "Has anyone had success blocking the latest versions of this annoying P2P application in a network-wide context? Previously, people have been told to block a specific port, etc, yet as expected, Kazaa has found an easy solution to this. Apparently, when a connection via default port is not available, Kazaa makes encrypted http requests through port 80, making it rather difficult to now block. If anyone has had success in doing so, I would love to hear from you."

Just upgrade you packeteer packetshaper to version 5.3.0. This image has new code to specifically handle KaZaA 2.0.

More information needed

Could you possibly be more general? Seriously, you are going to need to give people a better idea of your network setup unless you only want general answers on this, most of which will be moot in you environment.

That said, there are *plenty* of approaches to the problem of killing KaZaA (and KaZaA Lite), but they rather depend on the network infrastructure. You certainly need to filter the standard ports used by the program, and forcing all port 80 traffic through a filtering proxy server nay be of use. Also, P2P in general seems to need a fair amount of UDP traffic - depending on your setup it might be possible to restrict that to just those ports you require.
