Hi Jee,
at first you need to
modprobe ip_queue
and then you need to add a rule like this:
iptables -A INPUT -j QUEUE
to queue packets to userspace. But take care to at first run the sample program or modify the above rule to not queue every paket (e.g. only tcp dest port 80), otherwise your box will completely lose network connectivity because every packet would be queued to userspace but due to the lack of a program processing it in userspace never be returned...

Hi all,
I try to run the example code on libipq man page. Unfortunately, the program stops at
status = ipq_read(h,buf,BUFFERSIZE,0);
It seems the program is waiting for packets input into the buffer, but packets never go in. Can anybody help me? Thank you in advance!
Jee
