SocketSniff allows you to watch the Windows Sockets (WinSock) activity of the selected process.
For each created socket, the following information is displayed: socket handle, socket type, local and remote addresses, local and remote ports, total number of send/receive bytes, and more. You can also watch the content of each send or receive call, in Ascii mode or as Hex Dump.
This utility works on Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7 (32-bit only). Older versions of Windows are not supported.
