 Monitoring Net Traffic with OpenBSD's Packet Filte

Sys Admin Magazine tells us how to use OpenBSD's Packet Filter.

"Because the bandwidth costs me actual dollars for usage and over-usage, I needed to monitor how much is used, and by whom. This would be easy to solve if I controlled the upstream router for the box, but I don't. However, as I was setting up tighter security on my OpenBSD machine, I noticed that the Packet Filtering firewall software could give me statistics on named rules. By naming the rules that pass traffic, I could query the pf subsystem frequently and get traffic data. Problem solved!"
