Summary


The Conversations window lists information pertaining to communication between two hosts.

The Endpoints dialog lists details pertaining to the devices connected to the network.

Wireshark Summary is an informational feature, which offers a granular form of data, filters, and the trace file.

The Protocol Hierarchy window lists information in a tabular format pertaining to distribution of protocols used by the network endpoints.

Use the Follow TCP Stream option in Wireshark to read the plain text data from captured packets. There are different viewing options available such as ASCII, and Hex.

A command-line tool gets installed when you install Wireshark. The most common tool used is Tshark, which works in a similar way to Wireshark and tcpdump. It uses the pcap library that is used by other major protocol analyzers.

With Tshark, you can listen to live networks or work with an already saved capture file.
