title: How can I edit and tamper packets at will?
body: <p>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 <a href="https://www.secdev.org/projects/scapy/" rel="nofollow">Scapy</a> and <a href="http://code.google.com/p/libcrafter/" rel="nofollow">libcrafter</a>. <a href="http://netdude.sourceforge.net/" rel="nofollow">Netdude</a> is great as well, but the project is not maintained by the author.</p>
  
  <p>What better options are there? </p>
