[LARTC] Re: Matching with Layer7 vs. IPP2P

[Arik Raffael Funke <arik.funke@gmx.de>]

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,
Arik
