[LARTC] How to fight with encrypted p2p

2007-11-11 Thread sAwAr


Hi

I believe that whole question is in topic. 
Is there any way to recognize ( and then shape ) p2p traffic which is encrypted?
Modern p2p clients have this ability moreover some of them have this enabled by 
default. 
Now I'm using ipp2p for iptables but as I know this doesn't recognize encrypted 
traffic.

Thanks in advance.

Pozdrawiam

Have not tried this. An idea. P2P initiations are not encrypted AFAIK. 
Thus connections can be marked and related traffic shaped. If initiation 
is also encrypted, then I think we have a serious problem.

Some clients P2P clients are nice about there encryption and negotiate  
encryption ahead of time using plain communication. I.E. Limewire,  
Azureus.  However, some just start TLS and that is all you can see.


Looking at ipp2ps signatures, I don't see anything that leads me to  
believe they track that kind of info.
