iftop

So I'm reading TaoSecurity blog, and he's got a cool little entry about hooking into a hotel's wireless network. In the entry, he talks about iftop, which is a simple application that does for network traffic that top does for CPU usage.

So I install the port and run it, and of course now I'm freaking out. Probably a case of too much information, with too little knowledge, but there's all kinds of ports (446, 2460, 2490) that have some (a very little) traffic on them that I just don't know what they are doing. Perhaps just pings to see if there is anything interesting on my machine, but still, worrisome.

My weekend project - install a firewall!
