This is a q regarding networking rather than broadband, but i couldn't find a better place to put this

I'm running a network with 5 puters behind a adsl routermodem(Cisco 677i) via a 10mbit HUB.

What i would like to do, is monitor how much BW each user is using on the network .... The Cisco router only gives me the totals being sendt over the network... packages etc.

As all the users(lying bastards) complain on slow response on web and claim they hardly leech, and i would like to pin out the one stealing all our precoius bw

Does anyone know a way(if there is one without getting any new hardware) i could do this it would be appreciated

cheers ......
