[olug] Bandwidth Metering

[Charles Bird]

I was trying to use smoothwall but it was becoming a pain to get the thing to pass packets to the servers.

Now I am using slackware10.2 without alot of extras, its only using 38MB RAM :)
I have 385MB installed.

I am doing ipforward.
so here we go with my attempt of a text diagram....

[internet]<-->[cable modem]<-->[slackwarertr1]<-->[prolianthell]
Where slackwarertr has eth0 and eth1
Where proliant hell has a range of 16, perhaps soon 32+ IPs from cox. :)
I just want to make sure that someone isnt using 200GB upload a month on my 1Mb upload line.
I dont want to limit...I want to charge extra if they really need to do more.
