you can use iptables connmark extension (from patch -o-matic) to mark all packets from connection, ie:
iptables -t mangle -N detect-abusers
#if string kazaa detected then connection will be marked
iptables -t mangle -A detect-abusers -m string --string 'KaZaA' -j CONNMARK --set-mark 0x1
#check if connection is marked, if not inspect packet
iptables -t mangle -A PREROUTING -m connmark --mark 0x0 -j detect-abusers
#set packet mark with those from connmark
iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark
and now you can use:
tc filter add dev eth0 parent 1:0 protocol ip handle 1 fw classid your_kazaa_class
i don't use string match so i'm not sure if that would work - personally i detect "abusers" by destination port (well known ports http/smtp/pop3 are allowed at full speed)
