Wanna see something scary? Run Aquisition for a while, so you’re established on the network (I suppose LimeWire would work too). You don’t have to do or host anything, just run it. Now install tcpflow, which is like tcpdump, but shows you *everything* passing through your network and run
sudo tcpflow -i en0 -c
Congrats — You’re a porn portal! Or at least the rest of the world is trying to treat you like one. Discovered this by accident when my router lights were going crazy and tcpdump showed so much traffic I thought I was being DOS’d or something. Forgot I had left Aquisition running. tcpflow output tipped me off that something wasn’t right, since there are no brittney or “naked teen” refs on betips.
