Wireshark Tutorial offline
Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets
and tries to display that packet data as detailed as possible.
You could think of a network packet analyzer as a measuring device used to examine what’s going
on inside a network cable, just like a voltmeter is used by an electrician to examine what’s going on
inside an electric cable (but at a higher level, of course).
In the past, such tools were either very expensive, proprietary, or both. However, with the advent of
Wireshark, all that has changed.
Wireshark is perhaps one of the best open source packet analyzers available today.
