Systems Books

This is THE BIBLE. This is the gold standard for the exposition of the TCP/IP protocol stack. Every other TCP/IP protocol book must be measured by the yardstick of this book. This is simply the most comprehensive book ever written on the TCP/IP protocol stack. It's crystal clear and utterly lucid. Stevens tome leads the reader logically, methodically and effortlessly through all of the layers of the TCP/IP protocol stack: the Link Layer (ethernet frames), IP layer, Transport Layer etc. All nuances of TCP/IP are discussed: Address Resolution Protocol (ARP), RARP, ICMP, IGMP, User Datagram Protocol, Transmission Control Protocol etc. In particular, the 135 page exposition of the transmission control protocol is a masterstroke. Application level protocols such as DNS, NFS, FTP, SMTP are discussed at length. TCP/IP Illustrated is Unix-centric. Given that the roots of TCP/IP are in Unix, every serious appreciation of the protocol requires at least a basic understanding of Unix philosophy. This book is a masterpiece of technical writing in Computer Science. Do not be mislead by the one negative review of this book on the spurious grounds that it is outdated. The TCP/IP protocol has not changed since the publication of this book in 1994. I have two copies of this book and will probably buy a third copy. I very, very highly recommend TCP/IP Illustrated Volume I.

It is a very good book for understanding TCP/IP protocol suite. It has lots of tools explained in detail to explore the different protocols on unix/linux based systems. Most of the protocols are presented well. It is a must have book for learning networking concepts. I highly recommend this book.

Either if you're a pro or a student, this book is a MUST-HAVE. "Buy it NOW, don't waste more time" is the best advice I could give to you.

This book has very well detailed TCP/IP information, unfortunately some of the information is outdated. The book is easy to follow, and would make an even better learning tool if updated. I bought the book since it was required reading for a class, but I would opt out for a younger publishing on this topic if I had a choice.

This is a good book that covers all the fundamentals of TCP/IP networking. Good illustrations. Seperate chapters for each common application protocols.

Thick Oracle book which is intended for developers who might need to understand the Oracle internals and administration parts besides writing SQL. It's useful for them working in other database also as the general database concept is simlar. Developers can now have more DBA knowledges after reading before on-going performing some DBA task.

Gr8 stuff for all the Oracle ppl.

A true masterpiece, and a great way to learn Oracle concepts. No more to say.

I have been an Oracle DBA for about six years and this book is still the one I turn to when looking for deeper insight into tough Oracle problems. The author recently published a new book on 9i and 10g and that one is also quite excellent. When it comes to analysis and clear writing style, no one can beat Tom Kyte for excellence. Highly recommended.

I bought this book on cheap clearance after the original publisher went out of business -- the best $12 I ever invested. Remembering even 10% of this book makes you better than 90% of Oracle developers, modelers and architects. Mr. Kyte's real world experience and reliance on solid examples instead of folklore makes this light-years ahead of any other Oracle book; it's the only Oracle book I re-read regularly. If you can afford only one Oracle book, this is it. And you may not need any other.

Firstly a warning, this is the second edition and covers Windows 2003. There is a third edition that covers the newer OS. I bought this book by mistake and it's too big (postage would be too expensive) to return. So buy with care.

This is a big book in terms of pages but the content is less than stellar. Don't expect to find too much on designing AD in real world situations such as integration with networking topologies and devices. Nor expect to find details on integrating AD with other Microsoft technology such as SharePoint. No this cookbook is really an administrator companion, and I think it does a pretty decent job in that but not more.

Very handy cookbook reference for my office bookshelf. I've used it a number of times, and it's more than paid for itself in expediting regularly-scheduled inquiries of our AD structure here at GEICO HQ.

Excellent reference if you work with AD on a regular basis either as an admin or a developer. Each "how to" offers methods for manually performing a specific task as well as (where possible) how to automate the task using code. Should be on every Windows admin/developer's desk.

Overall, this is a great book for reference.

There are a number of areas where I think the book falls short - all of the scripts are very hard coded scripts that don't tell you how to do some functions that would make their scripts actually useful (like "pull the list of users with attributes from a tab-delimited file and create them" or something similar, this would make mass creation of users actually useful, instead of "create user1, user2, user3, etc..."). I think that the writers expect you to be a VB expert (or at least close to it) if you're going to actually make the vb scripts useful.

Most of the scripts are "How to use a script to do the same functions that you can already do in AD with ADUC or another MMC", but I think that the most important thing for me about the book is what it inspires me to think of doing. Things that MS doesn't necessarily expect you to do. I'm still not seeing a way to add sidHistory to an object (MS does it with another applet - there is a way...), but there are so many things in the book that just have me thinking about how you can implement changes to an environment that MS says you can't do. What they really mean is "You can't do that with the GUI tools that we provide you".

I am so glad that this book was recommended to me by a guy I took a class on scripting from. I use this book everyday (almost). I even took it on vacation with me for light reading.

I have very much enjoyed my book on how to read tarot. There is so much valuable infomation and I am learning so much.

I love this tarot book, I have been doing the tarot for years and own a ton of books on said subject, Mrs Bunning is by far the best tarot teacher, I took her on line course and have her site bookmarked and decided to purchase her book, all I can say is I wished I had run across her book and course years ago would have saved me a ton of money on tarot books that try too hard to be mysterious and bogs the reader down with too many technical and confusing terms. her book brought the tarot experience together for me in a way no other book has been able to do. the book simplifies and demystifies the tarot and allows the readers own intuitive powers to kick in. I find myself going back over my tarot journal years ago and saying ahhhhhhh its much clearer now. by far one of the best tarot book on the market also her course is a must for any serious student of the tarot, Mrs Bunning is a true teacher in that she teaches the student to use a common sense approach to allow the cards to tell the story.

I first learned the Tarot in 1976. Now over 30 years later I am finding myself having to re learn them as a result of memory loss due to a brain tumor. I bought several books in hopes of being able to recover some of my memory and learn again. I found this book by Ms. Joan Bunning to be one of the best! The print setting is just right for me making it easy for me to see. I have many decks of cards but wanted to start again on the deck I first learned on, the Rider-Waite Deck. The layout of this book is one that is so simple but yet so very complete and I am enjoying it! Parts are even coming back to me. The "how to" format with 19 lessons in all starts at the very basics of the Tarot and moves on to more advanced concepts. Starting with part one, Elements of the Tarot, it covers the Major Arcana, Minor Arcana, The Spread, Daily Reading and much much more! The card descriptions are very comprehensive and again easy to understand and follow. Ever read something and say to yourself "huh? What did that mean?" well you won't do that here! Also there is over 175 illustrations using the same deck, Waite. There is even a Website for support!! I just love this book and I want to thank Ms. Bunning for bring the Tarot back to light for me!!!

Pay no mind to the "reviewer" behind the curtain who complains about only one layout and no reversal meanings. If you're a beginner, or like me, have tried for years without finding out how to read the cards, this is the only book you should buy, and is the only one you'll really ever need to explain the cards. When you're ready for other layouts and reversals, buy her other books! With Ms. Bunning's guidance, you will learn how to become one with the cards and develop your own style of communicating with them. Most of us try to memorize meanings, then while staring blankly at the cards, our minds lock up on us. What we need to realize is that the cards are the archtypes of humanity, and as we use them to understand their characteristics within ourselves, they actually "speak" to us about where we're been, where we're headed, how we feel, and what we have and haven't learned from our mistakes. They also tell us what we have yet to learn to reach our fullest potential. The focus of these lessons is on finding ourselves in the cards. Once we realize who we are, then we can read for others, as the archtypes that appear in our lives, also guide the lives of those around us. Don't rush. Take your time. Enjoy the adventure. You'll be amazed at how things come together for you. And, if you want a preview of her work, check out her website.

I love this book. It is easy to understand and it certainly helps me interpret the cards when I do my readings. It is very self explanatory.

This is not your typical business networking book. I found that although I call what I am doing "Networking" I wasn't getting results. After applying the items I learned in just the first 6 chapters, I have gone from 2-3 referrals to 8-10 in only the past 4 weeks. I am more than doubling my business and packed with ways to continue this momentum. I would recommend this for anyone who sells a product or offers a service. For an $11 investment, you learn more than a $300 Networking Seminar.

If you read one book on networking, this is the one to read. Burg's system focuses on how to network correctly, thus enabling you to build a pipeline of qualified, A-list prospects for your business. This book is a must-buy for anyone striving to build business referrals that will continue the gift of giving in the long haul. The questions Burg outlines in Chapter two are a key component of how one should begin to network from this day forward. In addition, he shares the one question that will change your networking process forever. It's a question so few know to ask. And if you use this question at your next networking event, you will immediately establish yourself as an expert who knows how to deliver value to your prospects and your customers -- and to the networking process itself. This book is extremely thorough in outlining a proven system for networking anywhere any time. Most important, Burg shows you how to enjoy the process. This book is a seminal part of my professional library. I use it daily as a reference to build my business.

Cannot imagine how I have made it this far in business without this book. Bob Burg's advise is priceless.

If you're looking to sharpen up your sales skills or expanding your contact base, this is a great resource and offers a ton of tips that can be easily implemented. It's more than just a networking book, although that's one of the main components, it's about getting to know people, forming relationships by genuinely caring about people. Everything in life is based on forming and building relationships and the people that have figured out how to get along with people, are usually more successful and just plain happier people. It doesn't matter what you sell or what company you represent, ultimately, you are the product. If you're wondering how to meet more people, get more leads, earn more business ... you'll learn these and more in this book.

This book has excellent and well developed ideas. Only criticism is the author gets a bit full of himself at times.

This book is well written and you don't need to use your imagination that often. T.J. Parsell goes into explicit detail of his life experiences. I highly recommend this book to anyone who has questions about young people in prison.

As soon as I finished reading this book, I went back to the beginning and read it again. I was blown away by Parsell's experiences and his courage to come forth and tell the truth. He made me realize how ignorant I was about life in prison. I learned a lot and thoroughly enjoyed his writing. Highly recommended!

I suppose my title is strange for a book about this subject---but it was really wonderful and I see everyone else liked it too. This is going to be a book I KEEP on my shelves, usually I get rid of the book after I read it. I couldn't wait to pick it up again. Most autobiographies I don't like, they don't tell the whole story, but T.J. Parsell really, really bares his soul to us and I thank him. And he's really come so far in life since his prison days.

There was just about every emotion and feeling there can be in this book. Love, hate, tenderness, violence, understanding, friendship, rage, openness, awareness, brutality, isolation, confusion, sadness and maybe even a little bit of joy.

What a book!! I'm going to write T. J. I'm so glad he turned out alright. The letters at the end made me cry.

I finished this book about a year and a half ago, it was so intense a read for me at the time, that I gave it away as soon as I finished it, I didn't even want it sitting on my shelf. It's one of the most depressing things I've ever read, ironically making it a great story, one of the best I've read. Really changed my perspective on things, I'm heterosexual and used to be fairly closed-minded about those who were otherwise, but now I'm not so quick to judge a homosexual person. Also, it is a real eye-opener for many I'm sure on the topic of male-rapes inside prison, and the injustices with this system in general. He got, what, $50 for robbing some photoshop with a toy gun? Ok so I can see giving him a month in the county jail, not 4 years in prison, get real. We need to demand for a reform in this country as far as this "corrections" system goes, even the horrors at Abu Ghraib are NOTHING compared to what goes on daily inside American prisons. I highly recommend this book, and "Inside by Michael G. Santos", as two very-worthy books on what life is like inside of walls and fences. This book will haunt.

I read a great review of this book on a writer's blog & couldn't wait to read it! It truly is a courageous story and I admire Parsell for sharing such difficult memories. Bravo!

I would love to detail all of the specifics of what I found interesting and helpful from the books and DVDs in this system, but that would surely take up more time and room than this space allows, lol. Suffice it to say that those Reiki recipients whom I have been working with for some time have commented that they notice an increase in Reiki power -- and they didn't know that I had been doing further study with Steve Murray's Usui Reiki system products; they simply knew something was different. As a newly-signed author myself, I love his writing style; Steve is straight to the point without unnecessary wording --- I like and appreciate that.
Steve Murray's books and DVDs and absolutely priceless and will remain in my personal library as invaluable reference materials in the years to come. I do and will recommend them to anyone that I believe would be interested. I also see that his new book and DVD will be released soon. I plan to purchase and study those also ;)
Namaste,
Raine

While many books, DVDs, etc. SAY that they will reveal the secrets of Reiki, the series written by Steve Murray really delivers.

Here you will learn all the Reiki symbols, the attunements for 1st level, second level, and Reiki master, and much, much, more.

Thoughtfully written, you will find everything you want in this series of books and I highly recommend purchasing them. They are a must for any Reiki healer's library.

I have always known that I had healing energy but in 2004 I began to read Steve Murray's books and receiving his attunements by DVD. It works. Beginning with - Reiki The Ultimate Guide, he teaches his students about the Reiki sacred symbols & attunements and becoming a Reiki Healer. I received my attunement for 1st Level Reiki from Steve's DVD. After that I went on and received attunements for the 2nd Level & read his books - Reiki Ultimate Guides 2 & 3. Steve Murray's method of explaining the sacred symbols and attunements makes it easy to understand and he hides nothing from his students. His book Reiki False Beliefs Exposed For All shows how honest he is with his students. I have bought his DVD and received the attunement to become a Reiki Master, but waited until I felt ready. First I bought the DVD's Reiki 1st Aura and Chakra Attunement and Reiki Healing Attunement - Heal Emotional - Mental - Physical - Spiritual Issues and received these attunements. Afterwards I felt ready, and received the Master Attunement by Steve's DVD program. Steve's program is thorough and easy to understand, and his unique way of teaching is effective. The knowledge and attunements have been very helpful for me while on my own spiritual journey. I would recommend Steve Murray's program for anyone that is interested in becoming a Reiki Healer or in expanding their own knowledge and intensifying their own abilities as an energy healer. Steve Murray leaves no stone unturned, and will leave you feeling enlightened, and stronger as an energy healer.

After being attuned to the 3 Reiki DVD's, I tried it out on 1 of my massage clients. He was more than willing to be my Guniea pig. I asked him not to tell me if anything was wrong, I wanted to see if I could figure it out on my own. While i was performing the session, i felt tingling going all over my hands & going up my arms. I wasn't sure if it was the Reiki or if my hands were falling asleep from holding them up for so long. They tingled all over his body. When our breif session (maybe about 15 minutes) was over, I asked him if he was sore all over. He responded, "Yes! How did you know?" I told him, "I just knew." Still not sure if it was the Reiki, his wife, who is a dear friend, reinforced it for me. She said, "He said he NEVER felt anything like it in his life. He never felt such heat generated from something that wasn't touching his body." I believe this is proof that the Reiki Steve's teachings and attunements work.

His books are so helpful in answering questions that he didn't have time for on the DVD's. So far, my favorite is the "False Beliefs" book. I started out with that book. The others reiterate it & therefore, I believe make the Reiki stronger because you can understand it better. Steve is a wonderful teacher and is so helpful in answering your questions. There is no doubt in my mind that he is an even better teacher in person. If I had the money to visit him in California, I would. He is a very special person. BDB

This is a great way to learn Reiki. I took a lesson for one and two attunments. But I get more out of Steve Murray's information. I have all of his books, DVD's, CD's. I can go back at anytime to study the information. This way I learn it even better and grow with it. I can't go back to a class unless I pay BIG DOLLARS!!! This is well worth it, it teaches you the same thing a class does. When I did the first attunment I truly felt something, more than I did at a class. It give me more consentration being by myself so I get the real feeling. It's amazing. I now have my Master through this wonderful program.

My alumnae group read this book to 3rd graders at an inner-city school and the kids loved it! We had a map and games to go with it and the program was a big success. I highly recommend this book for teachers.

My daughter told me that my young grandchildren love this book and the humorous way it was written. I found it through the reviews in here and wholeheartedly agree with the good ones and thank everyone for posting them. I haven't gotten to read it myself, as they are in another state...but I can assure you, it is a book to include in your little one's library! :D

This is a fun book and is a good way to get familiar with the States. My son enjoys reading it.

A hilariously told and illustrated story heart about appreciating where you are from and what you have. 'Scambled is a unique take on being in a state of discontent . Each State has its own (harmlessly and comically stereotyped) characteristics-- Wisconsin loves cheese, Texas hollers "YEEEHA!" The illustrations playfully keep your eye moving (the spreads are FULL of tiny side jokes) and the story keeps the pages turning. Lost along the way (and maybe why it's so successful) is that the reader will have learned some geography along the way. What an entertaining, engaging way to present fact and nonfiction to a child! A perfect companion to kids who are starting to learn about our country.

This book was fantastic for my 2nd grader to learn the names of the states. We started each state lesson by doing the Melissa & Doug USA Map 51-Piece Floor Puzzle. Then we would read "The Scrambled States of America" while the puzzle was made, so we could check where each state is located that the book mentions. After a day or two, my son loved to put together the Melissa and Doug USA puzzle, because it wasn't just pieces. Each state had a personality. So instead of just putting together a puzzle piece, the pieces would talk to each other. Nevada would be in one hand, and Mississippi would be in the other. "I love you", "And I love you". "I'll write to you every day. Bye" "Bye". Then he would put Nevada and Mississippi in their respective places. I should make a video of my kids doing the puzzle. It is hilarious. Even my four year old would get into it and talk about how Nevada and Mississippi were in love, and Arizona did not like the ocean ruining her hairdo.

This is thought provoking and great for stimulating thought about the way you want to present information at your next meeting.....great read, great ideas and will be using it as a reference book!

In the foreword, Guy Kawasaki said "So open your wallet. And buy it. Then open your mind. And read it. Then open your heart. And do it". I think you should do that with this book, and maybe before that check the presentation of the author at google:

http://www.youtube.com/watch?v=DZ2vtQCESpk

just to have a taste of the book.

Within half a day after receiving this book I included some of the principles it describes into my presentation. The results are truly remarkable, my thoughts come across much more powerful. Also people smiled after my presentation saying where did you learn to present like this, fun, entertaining and meaningful !

For years I've been urging my clients (I'm an Executive Speech Coach) to visually simplify the message... and now I have the perfect book to backup my request - Presentation Zen! Garr Reynolds is a master at presentation design - his ability to distill the message and reduce the visual slide noise is invaluable. A must read for every speaker who wants to learn to create a visually impactful presentation.

I am a scientist, and I have given hundreds of presentations. I was hoping that this book would be applicable, but it is not. Somehow, the "professional stock photos" suggested cannot convey scientific data. There were no substantive suggestions or guidelines in this book.

Perhaps if you are a motivational speaker "I live in a van by the river" this would be useful.

If you are required to give presentations that convey data (experimental results, financial data) skip this book.

Sorry I wasted my money,
Teresa

I recently purchased this book based on the rave reviews even with an updated second edition off the press. I can honestly say that this book is Awesome in detail and explanation and is still extremely relevant to understanding the how too's and processes involved in routing tcp/ip. The most amazing feature about this book is how well explained and the book makes topics that would normally seem dificult or confusing easily understood, in other words grandma could learn how routing tcp/ip works from reading this book!

Great book for understanding IGP in details.

If any book was ever considered as the MUST HAVE BIBLE for Interior Routing Protocols - then Jeff Doyle's first effort on IGPs is THE book (how many cliché's do you want in one sentence)!! The book goes through at a very even pace - dissecting and describing the majority of both open-standard IGPs (OSPF, RIP and a little on ISIS) and Cisco-proprietary IGPs (IGRP and it's beefier brother - EIGRP). The book also includes some invaluable appendixes - including tutorials on working with Binary and hex.

But let's focus on the book's main reason for being - explaining IGPs. Take for instance OSPF - one of the most popular and widely implemented routing protocols in use today. On page 416-417, the book correctly discusses virtual links as a type of network type. The OSPF chapter typically employs 5-8 routers (and shows the required configs). Such a daunting exercise may at first seem like overkill, but Doyle is able to show how (and why) the all these router configs are necessary (to show, for instance, how they interact with or whether a DR or BDR). The book does have it's typos though, as the table on page 484 incorrectly documents stub networks as allowing type 5 and 7 LSAs (not so - thus a stub!)

I cannot imagine there are many CCIEs out there that do not have this book on their bookshelf.

I give this book 5 pings out of 5:
!!!!!

I am reviewing Routing TCP/IP Volume 1 (ISBN 1578700418), part of the CCIE Professional Development Series from Cisco Press. This book is widely regarded as part of the "Holy Trinity" of CCIE preparatory books. In addition to CCIE prep, it is also highly valued as an essential desk reference for anyone pursuing a career as a senior-level routing engineer. The author, Jeff Doyle, having written the two most recognized tomes on IP Routing, is a respected authority on the topic. His writing style is very clear and not at all difficult to read, which sets him apart from a lot of the authors in the "high-end routing book" category.

The book is part of a set of two books. TCP/IP Volume 1 contains coverage of the major interior routing protocols (RIP, IGRP, EIGRP, OSPF & ISIS) and follows it with coverage of route redistribution, filtering and mapping. TCP/IP Volume 2 covers the BGP exterior gateway protocol and follows it with coverage of advanced IP routing issues. As someone who's come up through the CCNA-to-CCNP-to-CCIE-candidate path, I recognized all of the topics from the BSCI curriculum. All this book really does is takes them to another level of depth. I highly recommend this path of coming at the CCIE, because unless you've done it all and seen it all, there's way too much information to take in during a single reading. Reading the BSCI book first gets you familiar with all of the topics, so that you're not overwhelmed when reading the Doyle books.

While many pan this book as being outdated since it was written in 1998, my contention is that all of the covered topics are still fair game for the CCIE qualifying written exam and the book still retains all of its original value. There are a lot of topics which are on the test which are not in Doyle's books, but if you look at the CCIE blueprint, the topics covered in the books map exactly to the topics in the IP Routing & IP Multicast sections of the blueprint. You can't treat any book as being a one stop shop for CCIE preparation. That's impossible. The book would be the size of my desk. I would actually contend that, on the next rewrite, they should break the 2 volume set into 3 volumes, one for the interior protocols, one for BGP by itself, and one for all of the advanced routing issues and multicast. This would make the volumes a bit less daunting and also somewhat easier to carry.

But, carry-ability issues aside, this is a very good book. It takes all of the topics to the degree of depth which you would expect for a CCIE-level book and explains things in a way that doesn't lose the reader. I had to work to keep the examples straight in my head, but no one said becoming a CCIE was easy. On the downside, the book contains no disc. This is unfortunate, because I always like to have the book on PDF. Also, it would be nice to have the review questions and answers put into a question bank. The book is also missing the "Do I Know This Already" section for each chapter, which is present in all of Cisco Press' certification guides. I realize that this is probably due to the fact that this is more of a desk reference / learning book than an official certification guide. However, as someone who's studying for an exam, I always like as many free practice questions as I can get.

I give Routing TCP/IP Volume 1 a 5 on my 5 ping rating scale and look forward to reading Volume 2.
!!!!!

Routing TCP/IP Volume 1 by Jeff Doyle (ISBN 1578700418) is an advanced level book on the theory and practice of routing and its implementation in Cisco routers. The 1026-page book (with a 50+ page index - always an important part of any technical book) is packed with useful information, example network architectures, and sample commands and their corresponding outputs to help the reader get a thorough grasp of real-life application of the theory.

The book is meant for working professionals in the network and routing field. Part I presents some basic routing theory along with the routing types - static and dynamic. This section, as in other books, is meant as a review for those seasoned engineers who have been working in the field for some time. It also helps to bring up to speed the other readers who may lack the necessary background. Part II contains the real substance of the book. It covers the interior routing protocols in detail including RIP 1 & 2, IGRP, EIGRP, OSPF, and IS-IS. The material presented in these chapters is definitely solid enough to give a detailed understanding of the subject matter and provide the necessary knowledge to allow one to troubleshoot the problems that creep up in maintaining networks running these routing protocols. Part III presents the issue relating to the optimization of networks running these routing protocols such as filtering and redistribution. Part IV consists of the appendices.

The most useful part of the book in my opinion is the examples and sample outputs. These really help the reader to understand the details on implementing the concepts presented in the book. Jeff presents a sample network architecture and uses that architecture to explain various aspects of the topic being discussed. For example, to illustrate various aspects of EIGRP routing and load balancing, a 5-router mesh architecture is presented followed by a detailed discussion of concepts such as succession, load sharing, route transitions and updates, etc. This approach really helps in understanding all aspects of a particular topic with concrete examples to relate to.

I took hold of this book not to help in preparing for the CCIE but to assist in the understanding of routing protocols that I use in my work life. As such, I can not comment on the applicability of this book to preparing for the CCIE exam but as for its application to real world scenarios, this book far exceeds any other on the topic of routing in the Cisco environment.

I am really impressed with the material presented in this book. The book is thorough and detailed in its coverage of interior routing protocols. Jeff Doyle is an expert in his field and this book proves it. On a scale of 1 to 5 with 5 being the highest, I give an enthusiastic 5 to Routing TCP/IP Volume 1 by Jeff Doyle. I can't wait to get my hands on Volume II.
