Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery tool, and packet sniffer. Note that Scapy is a very low-level tool—you interact with it using the Python programming language. It provides classes to interactively create packets or sets of packets, manipulate them, send them over the wire, sniff other packets from the wire, match answers and replies, and more. For downloads and more information, visit the Scapy homepage.

I love Scapy, Python on IP steriods. Worth every penny I would have paid if it were an expensive product.

Wow .. just wow. This is so great. I always dreamt of a tool like that, but never thought I'd get it. Brings out the little kid at christmas eve in me. Truly outstanding. Indispensable tool for everyone dealing with TCP/IP-based networks.

the most useful tool for networking at the packet level. It can help you build exactly the packets you want,manipulate packets in a way that makes sense... an more. Please take time to learn this application and of course Python programming is a prerequisite.

Ever since I was introduced to Scapy I have been amazed why it is not as popular yet it is the most useful tool for networking at the packet level. This can manipulate packets in a way that firewalls may not know what hit them!
