ulogipac is a powerful IP traffic accounting tool for linux routers and hosts. You can use the power of iptables rules to specify which traffic you want to account and which not. The size of IP packets sent to ulogipac through iptables is counted and buffered. After a configurable timeperiod you can submit the traffic information to your database servers (currently only MySQL is supported). You can specify 1 to N servers to send traffic information to.
