Product Description

Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well.

Customer Reviews:

  • Easy to Read - Real World Experience
    I found many of my questions answered very quickly and in an easy to understand format. Items like "Gad's Maxims" which you would think have nothing to do with network isues - have everything to do with how you will get your job done.

    The real world examples - even the more bizarre ones like the police cruiser crashing a system overnight - sound like Hollywood has some new ways to take over the world. you jsut can't make this stuff up.

    It was worth the time to read.

  • The author can write
    Most technical manuals are written in the driest tone possible. The author has the rare ability to write in away that is understanable and enjoyable. If you a looking for books on networking this book should be included in your library....more info
  • Excellent reference
    Not for the non-techncial or people just starting out. This is an exceptional book/reference to pretty much everything you need to design robust networks and a lot cheaper than the Cisco library!...more info
  • Great book for its target audience
    This book is exactly what it set out to be, "Everything You Need to Know That Wasn't on the CCNA Exam". This book is targeted at junior network engineers and provides for them a strong foundation of skills to build upon. It assumes a little bit of networking knowledge, but not much. This book is also great for server admins that have recently switched roles to the networking side of things or want to know a little bit more.

    Pros: This book is easier to read then other technical books that I have read. Gary seems to put a bit of realism into the technical topics citing problems that he has dealt with in his years of experience. This book covers many topics and gets to what you need to know quickly.

    Cons: One of the pros means that there is also a con. This is NOT a book that will go into great detail on the inner workings of protocols like TCP/BGP. It does brush up on these topics, but entire books have been written on these individual protocols, or high availability technologies, etc.

    Conclusion: This book is what it is advertised to be. It is a great book to form a foundation of networking skills, but it should be followed up with other books that dive deep into detail into a particular topic that is required for your job. I recommend this book to anyone wanting to learn more about networking as a whole, especially junior network engineers or recent college grads. ...more info

  • The best networking book of 2007!!
    Network Warrior by Gary Donahue may just be the best gem of 2007. I purchased this book solely based on Richard Bejtlich's glowing recommendation. To be honest, I'm typically a little weary of these `all-in-one' books, because it is hard to master `all' areas (not to mention to easily discuss `all' areas). Unquestionably, Mr. Donahue has been able to buck this trend by providing a great resource that answers many questions efficiently and quickly.

    To begin with, where does most networking start - layer 2, correct? Concerning NICs and layer 2, most people take auto-negotiation to be (dare I write) plug-n-play. This is the first book I've seen where it discusses `parallel detection'. Donahue is correct on page 20 as stating auto-negotiation is a protocol. He goes on to explain the `why was it built like this' of auto-negotiation. It actually makes sense now. I showed these 2 or 3 pages to a couple of other network engineers, and they both found this information to be both novel and enlightening. Right from the start, I knew I was going to be hooked on this book.

    Another gem in this book, this is the first book where I see Dr. Radia Perlman's `Algorhyme' rhyme printed since Perlman's own book. Again, probably stupid, useless info to most, but Donahue gives the foundation for a lot of the topics discussed. The discussion starting on page 207 for the 6500 backplane, Chapter 18 dedicated to the 3750, the section starting on page 156 discussing GRE tunnels and the pits and perils of recursive routing, Content Switch Modules starting on chapter 28 - all topics that are both helpful and well documented in `Network Warrior'.

    I could go and on about this book. Overall, this is a great book. I've gone back to it at least 5 times a week since I purchase it last month. I can't imagine a better resource.

    I give this book 5 pings out of 5:

  • A good book, but weak on routing.
    I like this book, but I found it was weak on the contents of routing, it seems that the author's knowledge limited for routing, the reader will be easily confused for this part. I recommend "routing tcp/ip" for routing....more info
  • Well worth purchasing!
    I don't normally write reviews, so that in itself should mean something. This book is great for anyone who wants to get an overview of many aspects of networking, or for the current professional who wants an easy to understand refresher. The details given are just enough to keep you interested and learning, but not too much that it will leave you bored and confused. This book covers a lot more than a CCNA level person would know, so I consider it a great step if you're working on a CCNP, or just interested in deciding what topic you should master next. It also covers a lot of real-world material, which is usually not in most other Cisco books. This book is definitely worth the read!...more info
  • Absolutely a must have for network admins
    This book is definitive++ when it comes to network adminstration. Gary Donahue covers nearly all aspects of network administration focusing considerable time on the administration of the appliances themselves. Each topic covered starts with the theory behind the topic. This includes diagrams and picture representations that help clarify the topic. Then the chapter moves into more specific explanations concerning real world implementation. Finally actual adminstration is show by display the command typed into the routers themselves and the responses recieved from the command. The author also talks about various misconfiguration issues and the consequences that result. The organization is clear throughout as this theme of starting with the general and moving towards very detailed examples is kept for each topic in the book. Network admins will love the attention to detail and the careful coverage of each topic. One of the best chapters is actually an extra one at the end that talks about the behavior and personalities of computer admins in general. This was quite entertaining and in my opinion quite true. The most informative chapter would be difficult to call because so many issues are covered. Personally I was helped by the spanning tree chapter and the multiple chapters covering the VLANs. This book had the clearest explanations I have seen to date. Put this tool in the network toolbox....more info
  • Excellent practical info for all network admins and designers
    I don't know why the title page on this book says "Everything that wasn't on the CCNA Exam", because that might mislead some people to believe that this book is extremely Cisco-specific or is for network admins that are just starting out. Neither is true. Instead, this book is a very good survey of the various skills, network equipment, and technology that you need to know about in the year 2007 to be a successful network administrator and for that matter, successful network designer. This book is Cisco-centric in that mentions problems and algorithms specific to Cisco equipment, but it should be useful to anyone involved in network administration and design. Also, if you are a student taking a course in computer networking, this book is full of accessible explanations that you might not find in your typical textbook.

  • Maybe the best book I will read in 2007
    Network Warrior is the best network administration book I've ever read. I spend most of my reading time on security books, but because I lean towards network security I like reading complementary sources on protocols and infrastructure. Gary Donahue has written a wonderful book that I highly recommend for anyone who administers, supports, or interacts with networks. Network Warrior may be the best book I will read in 2007.

    Why is Network Warrior so great? I think the key is the author's willingness to share personal recommendations. There are plenty of books about technology and syntax. I've read and reviewed many, most of which I liked for what they offered. However, it's rare to read a network book that says "here's how you should implement this," rather than just list options. I'm at the point in my career where I know what I might do; now I want to know what a real expert would do. Donahue provides that wisdom in many sections, but especially in Part VIII on network design.

    A second reason I really enjoyed Network Warrior was its coverage of a variety of Cisco features. Sure, I had read of many of these elsewhere, but I thought Donahue made many of them clear, especially in comparison to each other. There are better references for ACLs, like Cisco Router Firewall Security by Richard Deal, but when ACLs are described next to route maps or VLAN maps, Ciscoland becomes a little easier to understand. Donahue's explanations of EtherChannel, switching algorithms, and autonegotiation are other good examples. I even admit that the author corrected my misunderstanding of QoS, as he says "QoS does not limit bandwidth, it guarantees it, which is not the same thing" (p 429). Elsewhere he says "When there is no congestion, any protocol can use any amount of available bandwidth it needs" (p 428) and "while scheduling of packets always takes places, the limits set are really only enforced during congestion" (p 427).

    The third reason I like Network Warrior is the attention paid to understanding the fundamentals of certain technologies and products. The author ensures the reader gets a real grounding in telecom terms and technology, like T-1 lines. For products, I liked chapters on the 6500 series switch, content switches, and layer 3 switches.

    Finally, the writing is exceptionally clear. The diagrams are excellent and make their point very well. The author's suggestions for being a better administrator apply to any technical operator. I liked Donahue's repeated suggestion to "never assume anything" and to start troubleshooting at layer 1.

    Although I rated Network Warrior five stars, in a second edition I would like to see more on layer two fundamentals. I would also like to read about 802.1X and perhaps even Cisco NAC, since it seems to be becoming popular. Overall, however, you should buy and read Network Warrior right now. I loved it and will recommend it to anyone who wants to be a better network administrator....more info
