pmacct is a package that contains a number of daemons capable of different things. pmacctd can listen in promiscuous mode (on a switch span/monitor port) or simply capture all traffic which passes through an interface (if the linux box is routing the traffic) and aggregate that traffic according to various rules and write to a sql database or text file. It uses libpcap style rules like tcpdump so it is very flexible. nfacctd and sfacctd take netflow data exported from ciscos and sflow data exported from HP and other devices respectively and give you similar functionality as pmacctd without your linux box having to see the traffic pass it's own interface. You can of course collect traffic data from multiple devices in different parts of your network. Basically none of this is related at all to RADIUS, so I suggest you join the pmacct list if you have any further questions. The only bit that may need to be integrated with radius is the source IP lookup if your users don't have static IP addresses... Cheers Peter On Wed 27 Jun 2007, Liam Farr wrote:
Hi, PMACCT seems interesting, I assume I could setup a Linux router that supports one of those protocols? My ISP just provides me with a single connection with both national and international piped down it.

This information is very unlikely to be available via RADIUS accounting.
Your NAS (or your border routers or core switches) may however support netflow, sflow or jflow though in which case you should look at http://www.pmacct.net/ (An opensource project I am also involved with) or Traffic Sentinel http://www.inmon.com/products/trafficsentinel.php (Not open source but VERY powerfull)
