Figure1.1, “Wireshark captures packets and lets you examine their contents.” shows Wireshark having captured some packets and waiting for you to examine them.
Wireshark can capture traffic from many different network media types - and despite its name - including wireless LAN as well.
Wireshark is one of those programs that many network managers would love to be able to use, but they are often prevented from getting what they would like from Wireshark because of the lack of documentation.
This document is part of an effort by the Wireshark team to improve the usability of Wireshark.
We hope that you find it useful and look forward to your comments.
The intended audience of this book is anyone using Wireshark.
Wireshark is perhaps one of the best open source packet analyzers available today.
However, to really appreciate its power you have to start using it.
However, with the advent of Wireshark, all that has changed.Wireshark is an open source software project, and is released under the GNU General Public License (GPL).You can freely use Wireshark on any number of computers you like, without worrying about license keys or fees or such.Although Wireshark captures packets using a separate process the main interface is single-threaded and won’t benefit much from multi-core systems.Older versions of Windows which are outside Microsoft’s extended lifecycle support window are no longer supported.
Which media types are supported, depends on many things like the operating system you are using.
