Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal , the project was renamed Wireshark in May 2006 due to trademark issues.

A packet analyzer used for intercepting traffic on wireless networks is known as a wireless analyzer - those designed specifically for Wi-Fi networks are Wi-Fi analyzers. [ a ] While a packet analyzer can also be referred to as a network analyzer or protocol analyzer these terms can also have other meanings.
Using port mirroring (sometimes called Span Port) is a very common way, as well as physically inserting a network tap which duplicates and sends the data stream to an analyzer tool for inspection. Deep Packet Inspection (and filtering) enables advanced network management, user service, and security functions as well as internet data mining ...
Wireshark, or also named Ethereal, is a widely used open-source eavesdropping tool in the real world. Most of the features in Ethereal are packet-oriented and contain a TCP reassembly option for experiments on tracking intrusion attempts.
The Sniffer [1] was a computer network packet and protocol analyzer developed and first sold in 1986 by Network General Corporation [2] of Mountain View, CA. By 1994 the Sniffer had become the market leader [ 3 ] in high-end protocol analyzers.
In promiscuous mode, some software might send responses to frames even though they were addressed to another machine. However, experienced sniffers can prevent this (e.g., using carefully designed firewall settings). An example is sending a ping (ICMP echo request) with the wrong MAC address but the right IP address.
A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel. Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol ( networked or point-to-point ).
