NSE: Getting IP address from a captured packet

[Nick Nikolaou <nikolasnikolaou1 () gmail com>]

Hey everyone,

I'm working a script that sniffs packets on the network and adds the IP
addresses to newtargets. (
https://secwiki.org/w/Nmap_Script_Ideas#targets-sniffer)
Using pcap_receive() I'm able to capture packets but I'm not really sure
what Layer 3 data pcap_receive() returns and I'm having trouble getting the
IP addresses from the packets.

Can anyone shed some light on this?


Thanks
Nick
