As an educational tool, TcpCatcher will help understanding any tcp based protocol. Fully multithreaded and 100% java based, it is portable, fast and reliable and it has many useful extra features like sorting, filtering, built-in search engine, dec/hex packet editor to help you analyze captured traffic.

TcpCatcher can be run as well as a desktop application as a background process launched from the command line or from its api.

Get TcpCatcher and take it for a spin to see what it can do for you!
