Ms. Chappell is a member of the High Technology Crime Investigation Association (HTCIA) and an Associate Member of the Institute for Electrical and Electronic Engineers (IEEE) since 1989.

5.0 out of 5 stars Great Foundational Course of Instruction
Reviewed in the United States on February 17, 2012

I have used Wireshark several times in my work in software testing and even though I was able to use the tool to accomplish my test objectives, I always felt I could get much more out of Wireshark. I came across this book while studying for my CCNA and it looked like just what I was looking for to learn how to use Wireshark more effectively. The book provides a solid foundational level of instruction on how to use Wireshark to conduct packet analysis at the data link, network, transport, and application protocol layers. Using many examples, the book demonstrates how to use the various Wireshark capabilities to quickly identify correct, and diagnose incorrect, network behavior. The book provides a basic, sound, introduction to ARP, IPv4, TCP, UDP, ICMP and several common application layer protocols like FTP, POP3, SMTP, SIP, and wireless. The chapters on IO graphs and how to use Wireshark's statistics and graphing capabilities to conduct performance analysis and to detect network scanning were especially enlightening.

Each chapter ends with several practical exercises using packet files you can download from the book's website that help to exercise the key learning objectives in the chapter. Unfortunately, this is also the main deficiency of the book. None of the practical exercises come with a "text book answer" and the reader may be left wondering if they came to the correct solution. However, I found that if you carefully read the questions in the practical exercises and then re-read the main the points and examples in the chapter, the answers to the exercises were fairly straight forward.

Of course, the bottom line for any certification study guide is does it adequately prepare you to take the certification exam. In this regard, the study guide is right on target. Using this book and the companion exam prep guide, I easily passed the WCNA exam. Like other IT certification tracks, there is a lot of potential here for more advanced courses of instruction in network analysis. I hope to see these in the future.

4.0 out of 5 stars Like the Missing Manual Series
Reviewed in the United States on March 16, 2012

David Pogue should have granted Laura the money for this book and published it cheaper, because they both think alike in some ways. I'm going to bet they've either met before, and am sure they are aware of each other. This book is a bit pricey (drawing back one star), but you have to grasp the expertise involved. Laura has been in the "sniffing" business for quite some time. You will never meet another person so enthusiastic about Network Sniffing and such as Laura.

With that said, Wireshark is free. The competition is VERY expensive. What you get here is a way to appreciate the full benefits of such a powerful, but free piece of software. For the price of this book, you get the most out of Wireshark, and that's still amazingly inexpensive, should you consider the price of OmniPeek, NAI (Sniffer Pro), or even the super-incredibly, ridiculously, ludicrously, bloated-ly, and absurdly high priced OPNET Ace Analyst!

So, after having gone through this book, to some, it may seem fairly basic. I disagree to an extent. It's basic if you "believe" you are an expert, and if you've resolved a lot of common issues with sniffers. However, buried in this text are a few key gems that can easily be overlooked, but could save you time and sweat, trying to troubleshoot a nasty network issue, only to find out 3 hours later, it wasn't a network issue at all. Laura's tips and tricks are quite valuable. Pick them out and put them to use. You'll see!

Also, if you are looking to be certified, this is a VERY good start, and the money you can make troubleshooting tricky networked issues will pay for it. Or you will have a nice feather-in-your-cap resume' knowing you can dissect issues quickly and within minutes.

As far as readability, it's easy to follow. I don't believe I came across any real text (other than a minor typo or two) that mislead me, or confused me. It's well written, and if you keep to the outline, you will see just how it fits a good learning ethic.

5.0 out of 5 stars excellent resource

As a Network Forensic Analyst I spend all day sniffing packets, isolating and correcting network issues. I grabbed this book immediately because even though I've used other sniffers, and am sniffer certified, I use wireshark all the time. This book has been an EXCELLENT resource! It's divided up by protocol making it very easy to follow with Great Case Studies which provide insight into problems you might also be having. Because of how it's written, it's great for beginning sniffers, (as long as you have a good handle on the TCP/IP OSI model), and for experts as a resource to look up methods and technical info.
Bonus, if you read the notes at the bottom of the pages, and sometimes in the main text, you will find subtle humor which has made me laugh a few times. This is a fresh approach to an otherwise tedious task in writing a technical type manual. I've also attended Lauras webinars, which are also enlightening as Laura is a really enthusiastic and fun teacher.

Laura, GREAT JOB!!!

So I purchased this updated 2010 book after I'd gone through the 2008 CBT training by the same author. Laura Chappell's material is very consistent and detailed, with numerous elements which were not present in the CBT. This book is also a great reference for every day network analysis, in addition to being a great study guide for the Wireshark Certified Network Analyst exam. I really don't think you can go wrong with this book; I personally felt it was worth every bit of the retail value. Thanks Laura!

Very nice and dettailed wireshark guide.

The book is not only an introduction on wireshark, is a realy guide for network analysis with practical examples.

I never find a so detailed book on this topic.

It was exactly what I expected from this book.

The only negative astect is that the book is realy big and impractical to read (eg. in bed;-), it may be an idea to produce two books or better a ebook version!

Als TCSM Spezialist ist dieses Buch seit der Einführung von VoIP eine wertvolle Hilfe für mich geworden. Das Wireshark Computer Programm wird zur Beurteilung von VoIP Verbindungen benützt. Das Buch gibt tiefgreifende Einblicke sowohl in dieses Programm als auch wertvolle Hinweise. Als Anwender habe ich erst die wichtigsten Kapitel überflogen und mir danach jene Stellen gesucht, in welche eine vertiefende und mehrfache Betrachtung notwendig war. Obwohl das Buch einfach geschrieben und logisch aufgebaut ist, ist ein Basiswissen erforderlich.

This is one the best book I ever read about networking and if you want to become 'serious' about network traffic analysis you definitely will find this book extremely valuable.
Despite the fact that you are interested in the certification or not this book will give you a lot of information about the analysis of the most common protocols you can find in a network environment and how to analyse and interpreter them.
The exposition is clear and full of examples. You can download some additional material: more than 100Mb of captures and practice with it.
The section about how to use the graph and how to spot the most common problems and attack you can experience in a network environment is very interesting: after reading it I was able to prove to our IT department why our internet was so slow a suggest a possible fix.
I highly recommend this book! Enjoy :-)
