Wireshark

Capturing and analyzing raw network traffic is made simple with Wireshark. This tool can automatically identify thousands of different protocols and structure the raw data in a way that aligns with the layers of the OSI model. Seeing the packets updating in the software during a live capture can seem daunting at first, but by utilizing the powerful filtering it is possible to work with large data sets. VoIP telephone calls and any other TCP stream can easily be reconstructed.
