I've been learning scapy, which is an awesome tool. I have a colleague who is doing some research and had a need for a tool that could modify IP packets in arbitrary ways either from a pcap file or on packets in real time. The prototype sets the IP evil bit, recalculates the checksum and forwards the new packet.
