What tools or options do I have so that I can edit or tamper with Wireshark/tcpdump captures in any way which I want- be it IP headers, TCP layer, the payload part or raw packets? I have looked at Scapy and libcrafter. Netdude is great as well, but the project is not maintained by the author.
What better options are there?
I found one tool which, although a little slow, nearly fulfills the above said requirements.
It is Power edit pcap
