Creating Logging information of incoming packets

[Thesis]

Hi all,

how can i log the information about the incoming packets to the netfilter.

i am using the mangle table like this

sudo iptables –t mangle –A PREROUTING -p tcp -j NFQUEUE --queue-num 0

and i wouldlike to know how can i look whether all the packets are entering to it or not...

any ideas???

Two ways. You don't need a rule for it if you just watch the chains packet counters: list rules with 'iptables -t raw -nvxL PREROUTING' then sort by packet count or packet number. If you want a rule then add a "-j LOG" one before the one you listed with the options you need (see 'iptables -j LOG --help' or'man iptables').
