TCP Reset Injection Detection Utility

  The <NNSquad Network Measurement Agent (NNMA)> tool's available downloads are beta and include a Windows 2000/XP/Vista installer binary and <VC++ 6.0> Windows source code.
  TCP reset injection has been discovered being controversially used by internet service providers, such as <Comcast>, to disrupt torrent and P2P file sharing.
