	5:mk_nfque.lua    creating start_nfque.sh
	6:start_nfque.sh  nfqueue start_script
	7:stop_nfque.lua  nfqueue stop_script

Requirement)
	1:libnfnetlink,libnetfilter_queue (netfilter netlink library)
	2:glib2 (GNOME library version 2)

	5:Penlight (Lua Library) 
	6:lfs (Lua Library)

	install)
	  sudo yum install glib2 glib2-devel

		           libnetfilter_queue libnetfilter_queue-devel

	Lua library	
	 A)Penlight
	  ex)

Config)
	1:blackdb.conf  Batabase config
	2:nfqueue.conf  NFQUEUE config

	4:log.conf      zlog config

Install)
  tar xvf iptips-0.5.tar.gz
  cd iptips-0.5

1:make

2:edit passwd in your blackdb.conf.

3:edit nfqueue-number in your nfqueue.conf.
  if kernel >= 2.6.31 and iptables >= 1.4.5
  num = 1:2 
   ==>  -j NFQUEUE --queue-balance 1:2

4:mk_nfque.lua
  mk_nfque.lua ../conf/nfqueue.conf
   ==> start_nfque.sh

5:sudo make install
  default-target /var/lib/iptips

6:edit start,stop commands in your iptables-script.
  iptips.sh start
  iptips.sh stop
  ex)
    cat start_nfque.sh
    iptables -t raw -I PREROUTING -i eth0 -p tcp -j NFQUEUE --queue-bypass --queue-balance 1:2

7:register ipaddresses with the database.
  blackip -r 127.0.0.1 -p 123456 -a /home/proj/IptFW/Blacklists/blacklist.txt
  blackip -r 127.0.0.1 -p 123456 -c 5.5.5.5
  blackip -r 127.0.0.1 -p 123456 --list 5 -f /home/proj/IptFW/Blacklists/blackip_5.txt
