On my RH-E-WS-3 I would like to use iptables QUEUE. I am therefore looking, unsuccessfully, in /usr/include... for files containing nr_register_hook, and related things as documented on the excellent netfilter web site at: http://www.netfilter.org/documentation/HOWTO//netfilter-hacking-HOWTO-4.html #ss4.6 Thanks in advance for your advice.
