Go Wrapper For Creating IPTables' NFQueue clients in Go

Check the examples/main.go file

	cd $GOPATH/github.com/OneOfOne/go-nfqueue/examples
	go build -race && sudo ./examples

• Open another terminal :

sudo iptables -I INPUT 1 -m conntrack --ctstate NEW -j NFQUEUE --queue-num 0
#or
sudo iptables -I INPUT -i eth0 -m conntrack --ctstate NEW -j NFQUEUE --queue-num 0
curl --head localhost
ping localhost
sudo iptables -D INPUT -m conntrack --ctstate NEW -j NFQUEUE --queue-num 0

Then you can ctrl+c the program to exit.

• If you have recent enough iptables/nfqueue you could also use a balanced (multithreaded queue).
• check the example in examples/mq/multiqueue.go

iptables -I INPUT 1  -m conntrack --ctstate NEW -j NFQUEUE --queue-balance 0:5 --queue-cpu-fanout

You must run the executable as root. This is WIP, but all patches are welcome.
