I'm trying to identify applications which generate those traffic on our border routers. I use sampled netflow as data source and some flow-tools as analizer.
You will find that quite a few generators of network traffic (p2p apps, worms, at least some messenger clients) use more than one port - or in several cases, use completely random ports. Also - a whole lot of ports that are commonly used by p2p and messenger clients (before they fall back to random ports) are not listed in "well known ports" RFCs, or in /etc/services --srs -- Suresh Ramasubramanian (ops.lists@gmail.com)
