Анализатор протоколов - Wireshark is the world's foremost protocol analyzer
[ О приложении ]

Wireshark allows you to examine protocol data stored in files.
It supports dozens of protocol capture file formats and understands more than a thousand protocols.

It has many powerful features including a rich display filter language and the ability to reassemble multiple protocol packets in order to, for example, view a complete TCP stream, save the contents of a file which was transferred over HTTP or CIFS, or play back an RTP audio stream.

NOTE: This version of Wireshark does not support capturing data.
