I would recommend iptraf, ntop or ipac. Try http://www.topology.org/comms/netmon.html for some ideas. If you really want to do it with netfilter, try some rules like this: iptables -A POSTROUTING -t mangle -d a.b.c.d iptables -A PREROUTING -t mangle -s a.b.c.d Repeat for every machine on your network, changing a.b.c.d in each pair of rules to match the IP address of that machine. Note there is no target for these rules - this is deliberate (and correct). When you want to know how many bytes have gone to & come from each machine: iptables -L -t mangle -nvx When you want to reset the counters to zero (midnight on 1st of each month?): iptables -Z Regards, Antony. -- Ramdisk is not an installation procedure. Please reply to the list; please don't CC me.
