Hi all, i'm new to netfilter and just started trying some simple things.
I've made a program (simple program) to take a packet and print its metadata.
The output is this:
ID of queued packet: 3413885640
Netfilter mark value: 0
Packet arrival time (seconds): 0
Packet arrival time (+useconds): 0
Netfilter hook we rode in on: 3
Name of incoming interface:
Name of outcoming interface: eth0
Hardware protocol: 0
Hardware type: 0
Hardware address length: (null)
Hardware address:
Length of packet data: 0
Is this result valid? most values are 0

You are enqueing packets in the localout hook.
#define NF_IP_LOCAL_OUT 3

yes, in localout hook the packets are in network layer, so they don't
still know anything about the link layer information, that is, mac
address and folks.
