| Now we need to look out for all those P2P connections. We're going to find these out by looking for a client on the network making lots of connections to high port numbers, which is generally what P2P software does. This isn't foolproof of course: I have seen P2P software start to use port 80, and there could be false negatives, but on the whole it seems to work better than any other solutions out there that I have tried. | Now we need to look out for all those P2P connections.
