Question : Scan network for Peer-to-Peer

Hi!
Is there a way to scann an entire netowork for peer-to-peer users?  My network is getting slower and slower and I suspect that some users are using TorrentClient, Emule, ...  on the network
Thanks!

Answer : Scan network for Peer-to-Peer

I assume you are asking about ethereal?
You cannot really filter peer-to-peer traffic, but you can filter types of traffic that is occuring within your LAN. For instance you could have a look at SMTP traffic and say that is fine, then remove it from the capture using filtering. Then look at another service like DNS, and so on until you see an excesive amount of some type of traffic that you feel should not be typical for your network.
