bind callback is not work about python-netfilterqueue HOT 2 CLOSED

You need to accept the packet after you print it and you need to call run on nfqueue.

from netfilterqueue import NetfilterQueue

def print_and_accept(pkt):
    print(pkt)
    pkt.accept()


nfqueue = NetfilterQueue()
nfqueue.bind(0, print_and_accept)
nfqueue.run()

You also need to insert a rule in to iptables to queue the packets.

sudo iptables -I INPUT 1 -j NFQUEUE --queue-num 0

Remove the rule after with

sudo iptables -D INPUT 1
