Network packetsniffer (beta) program for WinXP and Win2000.

Sorce: NGSSoftware
NGSSniff is a network packet capture and analysis program. It requires Windows 2000 or XP, and allows users to capture, save and analyse traffic on their network. The current version of NGSSniff is a BETA test version, and is thus provided free of charge.


  • Clean, simple, fast GUI
  • Packet capture via Windows Sockets raw IP (WSAIoctl)
  • Packet capture via Microsoft Network Monitor drivers
  • Simple packet parsing (ip, tcp, udp, icmp, ethernet, arp)
  • Packet sorting
  • Import from Microsoft Network Monitor .cap files
  • ASCII view
  • Easy cut-and-paste operation
  • No need to install any drivers
  • Realtime packet viewing - no need to stop the capture
I have not tried this program yet but I'll give it a try later when I can find more time for an evaluation.

Hope someone will find this program useful.
