2. Who should read this document?
The intended audience of this book is anyone using Ethereal.
This book will explain all the basics and also some of the advanced features that Ethereal provides.
As Ethereal has become a very complex program since the early days, not every feature of Ethereal
might be explained in this book.
This book is not intended to explain network sniffing in general and it will not provide details about
specific network protocols. A lot of useful information regarding these topics can be found at the
Ethereal Wiki at
By reading this book, you will learn how to install Ethereal, how to use the basic elements of the
graphical user interface (like the menu) and what's behind some of the advanced features that are
maybe not that obvious at first sight. It will hopefully guide you around some common problems
that frequently appears for new (and sometimes even advanced) users of Ethereal.
