Command-line sniffer (packet capture tool) for Windows®

It is not a joke:

TCPDUMP for Windows® is a clone of TCPDUMP, the most used network sniffer/analyzer for UNIX, compiled with the original tcpdump code (tcpdump.org), and our own packet capture technology Microolap Packet Sniffer SDK (no libpcap/WinPcap/npcap).

What is under the hood?

How much?

But if you're going to use it for business purposes, welcome to order Commercial license — TCPDUMP for Windows® will save for you tons of your nerves and time if you are working in Unix/Windows heterogeneous environment.

What does it look like?


Nothing unusual: it looks the same as on Unix-like operating systems.
