Internet traffic

Share

I estimate (badly, I might add) that I currently use about 200gb of Internet traffic on my DSL link a month. If I’m going to move back to Australia sometime, that’s going to become a killer. Unfortunately, because my ISP doesn’t bill for traffic here in the US, they don’t appear to track my use at all. I think it might be time for me to do some tracking myself.

So, one of life’s little questions. Do I use pcap to snarf traffic on the DSL, or use iptable’s conntrack stuff in /proc? Just one more thing to ponder.
