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.
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!!!
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
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.
The book starts off with understanding the WireShark application and how you can customize the application to make it easier to find out what you are looking for. After that the book jumps into basic analysis and what features Wireshark has (Follow TCP Stream, Expert Systems, Graphs, etc) then dives into the nuts and bolts of popular protocols like HTTP/FTP/DNS/ARP, and the second edition include IPv6 which is great book. This is a great example of a company keeping up with technology.
I will say however, this book is not for the faint the topics are pretty advanced and the case studies go over certain scenarios however. There is also over a GB of extra information such as packet captures to compliment the book. So if you put in enough dedication you'll be able to master Wireshark.
