Add a few IPFW "count" rules to count the bytes and packets. Then,

SNMP (which isn't secure). A little bit of code in your favorite
scripting language will do it. And of course you can output to a
graphing package, though for me a simple histogram using asterisks
has sufficient precision in most cases.

Just curious.....but where is he going to run ipfw? I seriously doubt his router can run it, and what good is it going to do him to run it on a machine on the network if the network is switched? It's not going to be able to see any of the traffic other than what that specific machine is sending/receiving.


run ipfw in layer 2 after turning on promiscuous mode and attaching it to a hub.

I do it all the time.
