scapy

Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery tool, and packet sniffer. It can for the moment replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, and more.

In scapy you define a set of packets, then it sends them, receives answers, matches requests with answers and returns a list of packet couples (request, answer) and a list of unmatched packets. This has the big advantage over tools like nmap or hping that an answer is not reduced to (open/closed/filtered), but is the whole packet.

This package contains the Python 3 version of the library and scapy executable.

Scapy operates by allowing users to define a set of packets which it then sends and receives. It matches requests with answers, returning a list of packet couples (request, answer) and unmatched packets. Unlike tools like nmap or hping, Scapy provides the complete packet response rather than simplified states like open/closed/filtered.
