Comment (by ben@…):
A possible replacement for layer7 matching could be using the iptables
string match module instead. For example, I've used this to match
bittorrent traffic:
{{{
iptables -I p2pblock -m string --string "BitTorrent protocol" --algo bm -m
recent --rdest --set --name P2PBLOCK
iptables -I p2pblock -m string --string "BitTorrent protocol" --algo bm -m
limit --limit 1/minute -j LOG --log-prefix P2PBLOCK-seen-bitbm:
}}}
You could try this approach, porting the strings/patterns from the old
layer7 code.
