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.

Really disappointed

Reviewed in the United States on October 27, 2011

Frankly, this is one of the biggest disappoints I've purchased in a while.

First, let me say, I have not finished the book yet, so I'll update this later if anything changes...In fact I am writing this review as a warning to anyone thinking of buying this book. Unless you are an absolute beginner, I promise , you will be thoroughly disappointed , especially considering the price tag!!!

My Complaints:
1) The chapters that describe networking are downright careless with the use of the term "packet". As any network engineer worth their weight in salt knows, frame->packet->segment (i.e layer 2 MAC fram, Layer 3 source & dest IP packet, and Layer 4 source & dest Port). This author carelessly jumbles all this up in various places generically calling it a packet. okay, you say, well this is not a intro networking book and the author discloses that and provides good references....well in my opinion, this author should either remove the first few chapters or rewrite them correctly.

2) All of the case studies I have read so far(btw: I heard they were "really good", and are the primary reason I bought the book) are poorly explained...The author explains the symptom, then says they used wireshark to fix the problem. Huh? Well that's just great, what the heck did you do, I want screenshots, and step-by-step details. Otherwise it's just some worthless story.

3)chapters 2-4+ repeatedly reference free online material...like user guide stuff. These chapters talk about stuff like menus and user interface stuff... why is it even in the book if it's free online....Some might think it is necessary, but to me it is just filler.

Currently, I'm on chapter 14...
Sorry, at this point I cannot recommend any good alternatives...I'll keep looking.

Honestly, I've learned more about wireshark looking at free online videos and reading the online documentation.
That's it for now, I'll be back

One of the best networking books I've read

Reviewed in the United States on November 7, 2010

Verified Purchase

The first time I saw Laura Chappell was at the first Sharkfest conference. Her class instruction on protocols and analysis was outstanding, and this book provides the same down-to-earth / enjoyable experience in understanding not just Wireshark as a troubleshooting tool, but also how common protocols function as well as approaching different troubleshooting scenarios to find the source(s) of networking problems. I've been using Wireshark since it was called Ethereal years ago and this book still filled in quite a few knowledge gaps.

There are many networking books on the market, including your usual vendor-specific certification titles. Wireshark Network Analysis provides a practical way to dive into the sometimes-mysterious world of packets, headers, and communication patterns which other books don't cover. Many engineers know which buttons to push for device configuration, but lack a strong understanding of how protocols work. This book starts you on that journey with plenty of foundation material and then some.

I didn't give the book five stars due to the occasional grammar and technical errors that numbered a little too frequently for my taste (which are corrected in the errata), but overall I think it's very close. I got my WCNA certification shortly after going through this book.

WRITTEN FOR CERTIFICATION - NOT A REFERENCE BOOK

Reviewed in the United States on April 16, 2012

Verified Purchase

I read so many positive reviews that I thought it worth the 90.00 bucks. This book is written for anyone who is interested in becoming Wireshark certified in 2010 and not a Wireshark reference.

Wireshark is great program and tries to keep current with emerging technologies. The book doesn't, NEEDS UPDATING. It would be nice to have download addendum for registered book owners. "This is not on the test, but it is a gotcha." Checked web site, didn't find update.

I rated the book on the content and this is an observation. This would be helpful for newbies, it is hard to read a chapter on colors if the material is black and white.

Fantastic & extremely valuable book (despite of the certification)

Reviewed in the United Kingdom on November 20, 2011

Verified Purchase

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 :-)

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.
