Monitoring Traffic From Tap

view story

http://www.linuxquestions.org – Hi All, I am creating a hardware tap as shown here: http://www.instructables.com/id/Make...p6/Third-jack/ And I want some advise as to what I can use to monitor how much data each IP address is using per day/week/month/year. And also be able to see the current throughput rate and maybe even by which protocols? Perhaps use ipfire or smoothwall and somehow route to a virtual interface which is /dev/null? Has anyone any ideas or know of any OpenSource software which can easily do this? (HowTos)
