iptables has packet/byte counters built into it. If you do "iptables -vL" it
will show you the counts for each chains and rule within the chain. If you do
"iptables -vL -Z" it will zero the counters after displaying them.
I have the following set up as a cron job (make it weekly, daily, whatever):
iptables -vnL -Z | mail "[EMAIL PROTECTED]" -s "Bandwidth Usage"
