Hello all,

I was wondering how any of you do "accounting" on your networks connected 
to the internet.

For example I have one netbsd gateway to the internet, connected to some 
client machines.

I have been asked previously to give a list of bandwidth consumption for 
each machine (ip address).

Can anyone shed any light on this for me?

I've been using ipaudit, which counts control traffic and doesn't work 
easily for natt'ed addresses (not in pkgsrc?).

Ie. I listen on th eexternal interface, so of course all traffic is coming 
from th eone external ip. I could listen on both interfaces and compare but 
this seems a bit complicated.

I'm using ipfilter and was told it has some native accounting features, but 
does anyone use them?

Ideally would be:

-per day (or per hour)
-incoming.outgoing traffic per ip address, per port

For now I have squid with a small script to parse that and spit out http 
traffic, but I need total (pop3/smtp/chat) traffic.

Thanks in advance for any help!
