I have tried the l7-filter pattern, with no luck. Apparently, the big problem is that Skype traffic is encrypted, and so it is not possible to match it using fixed patterns. In some cases, it is possible to block Skype, as the existing pattern seems to match an important, but not yet encrypted packet. Shaping is however not possible, as the matched packet makes up very little of the traffic. -justin Andreas Klauer wrote: > On Monday 25 April 2005 15:08, Gary Smith wrote: > >>I need to detect Skype traffic using (I think it can be done) IP2P. > > > What's IP2P? > > I only know IPP2P, and I can't find anything about Skype on the official > homepage (www.ipp2p.org).
