Howdy
The topic of accounting RX and TX bytes intrigues me. I’ve been reading a few how to articles and it seems there is a varying opinion of whether or not to just rely upon iptables or something else.

I’ve looked at various tools such as collectd and pmacct and they seem like they’d fit the bill.
Basically if I was an ISP without specialized hardware; just say a Linux box on premises for resell of bandwidth and I wanted to charge the local hotspot provider based upon local devices and TX and RX usage. Why wouldn’t I try to have a script that reads iptables at a fixed interval and reports that out (really want the delta to build the big picture, since I know counters can get reset). I know another option is just do the aggregate on the upstream device; but I want to be difficult ;)
