Re: Matching with Layer7 vs. IPP2P

Linux Advanced Routing and Traffic Control

L7 compiled fine on Fedora Core 4 with kernel 2.6.12.6 with following procedure:
1. patched kernel sources with ipp2p using patch-o-matic-ng
2. patched kernel with the patch file from l7
3. patched iptables-1.3.5 with l7
4. make/install iptables
5. make/install kernel

I had to adjust the destination directories for iptables to fit Fedora's convention.

Best regards,

I was just about to post the same post,

I currently use ipp2p and it works pretty well, It just doesnt seem to track morpheous(fasttrack) protocols, otherwise it works pretty well. I have quite alot of connections and havent seen any performance issues. My next step is to add L7 as well with ipp2p to completely block/shape p2p.

However I find L7 bit more tricky than ipp2p to compile
Cannot comment on L7

Hi,

can anybody comment on the cost of matching with IPP2P vs. Layer7.

Also, does a iptables rule with more complicated matching mechanism also slow down processing if all the packets are matched before they reach the rule. I.e. is the mere existence of a potentially costly rule already slowing down processing or only if packets are actually processed by it?

Thanks very much in advance.

Best regards,
Arik
