Internet Routing Architectures (2nd Edition)

Amazon.com

Border Gateway Protocol (BGP) does exactly what its name implies--it routes traffic efficiently from its origin on one network to its destination on another. Most typically, it's the protocol that provides a private network with Internet connectivity. Internet Routing Architectures is an authoritative text on BGP in theory and practice, covering everything from good design of BGP-based internetworks to actual implementation of those internetworks on Cisco Systems routers. This second edition includes more information than its predecessor on BGP-4; other improvements are updates rather than major additions or revisions. You will appreciate having this book on hand if your job has to do with optimizing traffic under BGP, or if you're preparing for one of the Cisco certification exams.

Sam Halabi--a respected authority on Cisco routers--discusses addressing schemes and the ways in which routing protocols operate within those schemes. The general information serves mainly to set the stage for BGP, which Halabi explains lucidly in theory before getting into design issues and, finally, implementation via router configuration. The book presents practical situations ("Multihoming to a Single Provider," for example, which is subsequently broken down into sub-scenarios about how the multiple connections are used) and steps through the design decisions associated with them. It's also big on diagrams and uses one on nearly every other page to drive home points. The result: this book earns its cover price as a tutorial and as a reference. --David Wall

Topics covered: Means of connecting one network to another, especially by means of Border Gateway Protocol 4 (BGP-4) on Cisco Systems routers. There's coverage of addressing and routing-protocol generalities, as well as of BGP tuning for routing inside and outside autonomous systems. Design decisions are a big part of this book's scope.

Classic BGP and Internet Architecture.......2007-06-13

This is a really great book on BGP and Internet Architecture. The explanation of BGP at the protocol level is great. More importantly though is its explanation and examples of using eBGP / iBGP with an IGP.

I've heard it criticized as being dated and too Cisco specific. Though it is Cisco specific, it's still very relevant. I would start with this book and read past NANOG presentations on introductory BGP if I wanted to learn how the Internet works.

A great BGP book, but not the first book for the CCIE.......2006-02-01

I have always felt that I am part of the small minority that just does not see the beauty of this book if studying for the CCIE. I have, for years, read other's comments on the how Halabi's "Internet Routing Arch" is a `must have', yet I still have not found a similar reason why. While I do feel that the book does (probably) the best job at explaining BGP and how to implement BGP in a Cisco-centric world, I have not discovered the value for the CCIE. I would much rather spend my time with CiscoPress's "Routing TCP/IP" Volume 2, by Jeff Doyle and Jennifer DeHaven Carroll than this book.

One item of concern, there is a noticable amount of trivial errors in this book that can lead to disaster if implemented incorrectly. For example:

Page 106 - "...any traffic that has an origin OR destination that does not belong to the local AS." This clearly should be an AND, not OR.

Page 315 - "You can also specify a PREFIX list..." - I believe this should be a filter list, not a prefix list.

And then there are places where the book is too opinionated - for example - page 206 "Many operators choose to filter dynamically learned defaults to avoid situations in which traffic ends up where it is not supposed to be." I do not feel this is true, and can think of multiple times when not filtering the advertised default route may just end up being the worst option. In fact, I do not feel either configuration is the right configuration to admit or condone, as the wrong configuration can have disastrous effects.

I still have to give this book 4 stars - simply because of it's utilitarian value and overwhelming sense of loyalty given to this book by others. But I don't reach for this book too often.

I give this book 4 pings out of 5:

Excellent guide to unfold the mysteries of BGP.......2006-01-20

Internet Routing Architectures is considered the BGP4 handbook and rightfully so. I found the overall composition easy to read. Even though the book is aimed at varying levels of expertise, it does not assume any level of knowledge in TCP/IP or routing. It explains all the concepts, from the simplest one right up to the most demanding, in a fluent way. The book works hard not to withhold protocol details and design-oriented information, while at the same time realizing that building general understanding comes first. An in depth look at BGP is supplied here from the theory aspect, if you need actual configurations and commands I suggest also:

Cisco BGP-4 Command and Configuration Handbook : CCIE Professional Development

Configuring BGP-4 on Cisco Devices.......2005-09-02

This is a good book, let there be no doubt about it. But in my opinion it goes beyond the scope of the 682-661 exam for which purpose I bought it. However, every ISP backbone routing engineer should have this book with him and use it as a dictionary in case of.

Best BGP Book!!!.......2005-08-15

This is the best BGP-4 book out there in preparation for the CCIE. Do not waste your money on others this is the one that you need. It takes you from the beginnings of the Internet to the current uses of the protocol. This book is a must have.

Book Description

Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly.

That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right.

Thoroughly revised and expanded, Cisco IOS Cookbook, 2nd Edition, adds sections on MPLS, Security, IPv6, and IP Mobility, and presents solutions to the most common configuration problems, including:

Configuring interfaces of many types, from serial to ATM and Frame Relay
Configuring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP)
Configuring authentication
Configuring other services, including DHCP and NTP
Setting up backup links, and using HSRP to configure backup routers
Managing the router, including SNMP and other solutions
Using access lists to control the traffic through the router

If you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced--if you've just been given responsibility for managing a network with Cisco routers--this book could be a job-saver.

Great book for Cisco router admins.......2007-05-08

This book should be on every Cisco & network admin's shelf! If you manage several Cisco routers, this book is packed with loads of time-saving tips, tricks, scripts, and real world solutions to make router management easy and take the pain out of repetitive daily processes. Some Perl & Unix knowledge is helpful as well as some basic "CCNA level" understanding of Cisco IOS. Troubleshooting and configuration commands are taken to the next level beyond most boring and dry CCNA and Cisco Intro books.

cisco ios cook book its great book.......2007-05-06

always when i forget some of command i find in book, this is cool book..

Cover most of the topics.......2007-03-07

This book is indeed the best book for day to day management of Cisco networks. Although it covers most of the topics. However, there are some topics such as DMVPN, IPSEC VTI etc. are missing from the configuration examples.

The "CISCO IOS in a nutshell" covers DMVPN but misses on IPsec VTI. However, I still feel this is the best book written for cisco router configuration.

Wish I had this months ago.......2007-01-12

The first thing I noticed when I got this book was how much larger it was than the first edition. Next was that it covered quite a bit more. HSRP, Security, IPv6, MPLS just to name a few. It's straight forward, too the point. Not a ton of explanation so if you want to know WHY something works, this isn't for you. If you want to MAKE it work then pick this one.

This all-encompassing TCP/IP text defines completeness with its 1,000-plus pages and hundreds of configuration screens, exercises, charts, tables, and references. Though initially overwhelming, such thoroughness is what's demanded of those who ultimately pass the Cisco Certified Internetwork Expert (CCIE) exam, the bruising test for which Routing TCP/IP, Volume 1 serves as preparatory material.

Such a goal is evidenced in much of the three-part book's design. For example, nearly every chapter includes some combination of recommended readings, review questions, configuration and troubleshooting exercises, case studies, and summaries. In addition, there are numerous appendices devoted to answers to questions and exercise solutions as well as one that outlines exam preparation tips.

Jeff Doyle begins this volume with a review of several basic topics, including a chapter that outlines the parameters of TCP/IP itself. Though some may already be familiar with that material, the sections on dynamic and static routing serve as valuable review material for readers of all levels. The second part deals with TCP/IP interior routing protocols, such as Routing Information Protocol (RIP), Interior Gateway Routing Protocol (IGRP), and Open Shortest Path First (OSPF). The book ends on a challenging note with explanations of route redistribution, route filtering, and the like. Routing TCP/IP is required reading for those readers with the ambitious goal to both understand the protocol and excel on the CCIE exam. --Sarah L. Roberts-Witt

Book Description

A detailed examination of interior routing protocols

Learn the IP interior routing protocols with this approachable, practical presentation
Explore configuration and troubleshooting of IP routing with Cisco routers through case studies
Test and validate your understanding with practical, comprehensive review questions, configuration exercises, and troubleshooting exercises
Further your CCIE preparation while mastering the essential TCP/IP protocols

CCIE Professional Development: Routing TCP/IP, Volume I, takes readers from a basic understanding of routers and routing protocols through a detailed examination of each of the IP interior routing protocols: RIP, RIP2, IGRP, EIGRP, OSPF, and IS-IS. In addition to specific protocols, important general topics such as redistribution, default routes and on-demand routing, route filtering, and route maps are covered. The book emphasizes techniques for designing networks that efficiently utilize and integrate the IP routing protocols. You will gain a deep understanding of IP routing protocols and learn best-practice techniques for implementing these protocols using Cisco routers. As well, this book will help you master the skills necessary to become an effective CCIE.

Each protocol-specific chapter opens with thorough and lucid coverage of the protocol's capabilities and characteristics. Following sections contain configuration and troubleshooting case studies that cover Cisco specific configuration of the protocol and all commands available for it on the most recent Cisco IOS Software version. Finally, review questions and configuration and troubleshooting exercises on each protocol provide an opportunity to practice for the CCIE exam.

The Cisco effort to facilitate the creation of competent network operations center (NOC) and information systems (IS) staff is exemplified in its CCIE program. To support these efforts, Cisco Press is working closely with CCIE program management to create information products that help build the knowledge and expertise of NOC and IS professionals, as well as provide up-to-date, accurate information on technologies addressed in the CCIE program.

The CCIE Professional Development Series volumes are based on CCIE program guidelines from Cisco. This series is a set of technology-specific volumes designed to meet the needs of CCIE candidates.

This book is part of the Cisco CCIE Professional Development Series from Cisco Press, which offers expert-level instruction on network design, deployment, and support methodologies to help networking professionals manage complex networks and prepare for CCIE exams.

Routing TCP/IP Volume I Still Awesome and relevant!!!.......2006-08-10

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!

The best way to understand the world of IGPs.......2006-02-01

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:

A Bible for the Interior Routing Protocols engineers and designers.......2005-10-26

Great book for understanding IGP in details.

A Masterful Book on Routing in the Cisco Environment.......2005-03-24

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.

An Indispensible Tome.......2004-06-11

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.

Book Description

Reliable, flexible, and configurable enough to solve the mail routing needs of any web site, sendmail has withstood the test of time, but has become no less daunting in its complexity. Even the most experienced system administrators have found it challenging to configure and difficult to understand. For help in unraveling its intricacies, sendmail administrators have turned unanimously to one reliable source--the bat book, or sendmail by Bryan Costales and the creator of sendmail, Eric Allman. Now in its third edition, this best-selling reference will help you master the most demanding version of sendmail yet. The new edition of sendmail has been completely revised to cover sendmail 8.12--a version with more features and fundamental changes than any previous version of the Unix-based email routing program. Because the latest version of sendmail differs so significantly from earlier versions, a massive rewrite of this best-selling reference was called for. The book begins by guiding you through the building and installation of sendmail and its companion programs, such as vacation and makemap. These additional programs are pivotal to sendmail's daily operation. Next, you'll cover the day-to-day administration of sendmail. This section includes two entirely new chapters, "Performance Tuning" to help you make mail delivery as efficient as possible, and "Handling Spam" to deal with sendmail's rich anti-spam features. The next section of the book tackles the sendmail configuration file and debugging. And finally, the book wraps up with five appendices that provide more detail about sendmail than you may ever need. Altogether, versions 8.10 through 8.12 include dozens of new features, options, and macros, and this greatly expanded edition thoroughly addresses each, and provides and advance look at sendmail version 8.13 (expected to be released in 2003). With sendmail, Third Edition in hand, you will be able to configure this challenging but necessary utility for whatever needs your system requires. This much anticipated revision is essential reading for sendmail administrators.

This is more like a reference manual.......2006-03-02

This book probably covers most information regarding Sendmail but is not meant for someone trying to learn how to configure sendmail. Most chapters have a small introduction and then go on to explain each feature/aspect in detail. For a beginner, it is difficult to connect the dots (features) and understand how to configure / run sendmail.

Mandatory.......2005-08-08

If you take care of Sendmail servers, you should have this book. I've been using this application for almost 10 years, and I still learn new things all the time, and this book is primarily where I get my answers. Highly recommended.

There has to be better..........2005-04-18

I admire O'Reilly books for their uncanny ability to hook me into a lot of advance technologies. I desperately need to get a handle on sendmail for basic configuration, so naturally I come to O'Reilly.

I investigated this book several times, and though it looks like a great awesome and essential reference, it simply does nothing for those trying to get off the ground. I think it is only for advanced and seasoned sendmail administrators, but for those trying to get a handle on sendmail, this is not the book.

In contrast, I have books on postfix and exim mail systems by O'Reilly and these books are decent in getting you started. I am saddened that this is mainly a reference and not like other O'Reilly books. The book could have been called "send mail, the definitive reference".

Don't limit yourself.......2003-09-20

This is a great book if you are seasoned Sendmail admin with good C programming skills. I give 3 starts because it is so hard to understand.

I've been using sendmail for 3 years and I just tried Qmail and Postfix. I have chosen Postfix because it's so darn efficiant and configurable.

Viktor Duchovni, is a great help on the online community and the online docs are just as detaild as this sendmail book.

If you are stuck on sendmail then get this book.

But try Qmail and Postfix if you can...

BTW... RedHat lets you choose between Postfix or Sendmail. That means a lot to me.

the sendmail bible.......2003-09-18

If you are a mail admin and don't use this book, you are either doing it wrong or are a genius.

Anyone who is serious about sendmail administration and configuration must use this book.

Book Description

Written for TCP/IP network administrators, protocol designers, and network application developers, this book gives the most complete and practical view ever into the inner workings of Internet routing. The book focuses on OSPF (Open Shortest Path First), a common TCP/IP routing protocol that provides robust and efficient routing support in the most demanding Internet environments. A methodical and detailed description of the protocol is offered and OSPF's role within the wider context of a TCP/IP network is demonstrated.

Practical throughout, the book provides not only a theoretical description of Internet routing, but also a real-world look into how theory translates into practice. It shows how algorithms are implemented, and how the routing protocols function in a working network where transmission lines and routers routinely break down.

You will find clear explanations of such routing fundamentals as how a router forwards packets, IP addressing, CIDR (Classless Inter-Domain Routing), the routing table, Internet routing architecture, and the two main routing technologies: Distance Vector and link-state algorithms. OSPF is discussed in depth, with an examination of the rationale behind OSPF's design decisions and how it has evolved to keep pace with the rapidly changing Internet environment. OSPF topics covered by the book include the following: OSPF areas and virtual links NBMA (Nonbroadcast multi-access) and Point-to-MultiPoint network segments OSPF configuration and management Interaction with other routing protocols OSPF cryptographic authentication OSPF protocol extensions, including the Demand Circuit extensions and the multicast extensions to OSPF (MOSPF) An OSPF FAQ

IP multicast and multicast routing are also discussed. Methods for debugging routing problems are explained, including a catalog of available debugging tools. The book also offers side-by-side comparisons of all the unicast and multicast routing protocols currently in use in the Internet.

You will come away from this book with a sophisticated understanding of Internet routing and of the OSPF protocol in particular. Moreover, the book's practical focus will enable you to put this deeper understanding to work in your network environment.

Customer Reviews:

Great book on OSPF theory.......2007-07-24

I enjoyed reading this book.
The book was written by the author of the OSPF protocol.
There are lots of insights into why the protocol was written and the reasoning behing many of its features.
It was very nice to gain insight from one of the engineers who in my opinion helped to pioneer the internet.

A most readable technical book.......2002-02-07

The author has a conversational, almost tongue-in-cheek style for a highly technical book - makes reading much more pleasant. The history of the protocol development is most interesting (and maybe just a teensy bit biased). The contents are very thorough and concepts are explained clearly. Would rank right up there with Internet Routing Architectures by Halabi for informational value.

Good Introduction to Intradomain routing.......2001-10-10

If you are a technical guy with interest in understanding
what happens behind the scene of your IP network this is a good book. The only drawback is that in some point you have the feeling things are non fully explained (details left to the reader); it's possible Jhon Moy had some interest in selling the second detailed book on OSPF (The complete implementation ..").
Nice to compare what Moy says about OSPF vs. IS-IS with Perlman idea.

Ospf Anatomy of An Internet Routing Protocol.......2001-08-25

A clear and concise description of the protocol for the novice and experienced veteran. Good study and reference to keep while implementing the protocol for any developer.

Standards-based explanation of OSPF.......2001-04-08

I'm biased against proprietary protocols, so understand where I come from when I say that I wouldn't run any other IGP than OSPF. ISIS has a few strange things but thats not the point here.

This book gives the networking world a great explanation of how OSPF is designed to work as a standard, not how Cisco implements it (which, by the way, I think they do very well). Not only does Moy explain how OSPF works, but he tells us WHY he decided it should work that way. He also gives a brief history of the early OSPF vs ISIS conflict and OSPF's development process, including what was wrong with OSPF ver1. This book helps spare you from scouring the 1000 or so RFC pages that describe OSPF.

This book is a little pricey, and probably isn't necessary to get OSPF running (read Doyle), but it will deepen your understanding of the protocol and is written in clear, old-fashioned English.

Book Description

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances. The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:

Delivering and forwarding mail
Relaying
Masquerading
Routing mail
Controlling spam
Strong authentication
Securing the mail transport
Managing the queue
Securing sendmail

sendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread.

Just what I needed.......2005-08-08

Great book, exactly what I needed. I'm pretty good with Sendmail, but there is nothing like just looking up an issue and following through a solution. I would recommend this to anyone who works with Sendmail!

This book has something about sendmail for everyone.......2005-01-20

This book has something about sendmail for everyone.
I know sendmail very well, and have used it for years.

But even I and sendmail gurus I work with learned a lot.

this is a great book.

A must have for anyone who administers sendmail.......2004-08-27

Working with sendmail can be very challenging at times; while the documentation for it is very complete, finding real-life use-cases can be tough and messing up a configuration is very easy. Fortunately the sendmail authors and community adopted the m4 language to help make building and managing sendmail configurations less painful (I remember having bad dreams about sendmail configuration language when I started learning it). Even with m4, understanding what goes where when and why in a sendmail configuration file can be a real challenge.

O'Reilly helped we mere mortals out tremendously with the publication of "Sendmail: The Definitive Guide," a book that helped demystify and clarify many of sendmail's inner-workings and configuration options. Even with this book, it was still hard to answer real-life use case questions, like how to enable SMTP AUTH for sendmail, how do I use LDAP with sendmail, how do I use sendmail to accept email for multiple domains in a virtual hosting environment, how do I use blackhole list services?

Enter "Sendmail Cookbook." This clear, easy to read, well-indexed book contains a wealth of useful recipies that make previously difficult to figure out tasks quite easy. The book is organized in typical Cookbook fashion; each chapter or section stands on it's own, and if it does require knowledge of other sendmail configuration topics, the section includes cross-references to other relevant recipies and references to appropriate sections in the "Sendmail: The Definitive Guide" book, which is a nice additional feature.

This cookbook starts with recipies that step the reader through building and installing sendmail, with sections on configuring the build so that sendmail compiles with SSL/STARTTLS support, LDAP support, and SASL support. Chapters that follow deal with everything from enabling and configuring SMTP AUTH, to securing sendmail itself, to controlling spam. Recipies use m4 whenever possible and only dip into the sendmail configuration language when necessary, another feature I found very impressive.

I own quite a few O'Reilly books; this is one of a small number that I enjoy just picking up and flipping to a random page and reading; I always find something that I either didn't know or had forgotten. I wish I had this book seven years ago when I was struggling to learn the basics of sendmail configuration and administration; I might have more hair left if I had! I highly recommend this book to anyone who works with sendmail, be that daily administration or occassional troubleshooting.

Not for amatuers.......2004-04-30

This is definitely a book for systems administrators. You won't learn the basics about sendmail, or get an introduction. This book is for folks who generally know sendmail, but are having specific issues with it.

The first chapter has a lot of very specific fixes for a bunch of operating system specific issues. After that the solutions become a bit more general.

The two standout chapters are chapter four, on relaying, and chapter six on spam filtering. Both of these have great introductions and in-depth techincal descriptions, with effective graphics, covering the topics.

I recommend this book for systems administrators and for people actively using with sendmail.

A Much Easier Way to Handle Sendmail.......2003-12-31

The first killer application of the Internet was email. For over twenty years, the most common program used to handle this was sendmail, written by Eric Allman. Over this time, sendmail has become a fully fledged language, with a very inelegant syntax. To learn how this, you need the book "Sendmail" by Costales and Allman.

The basic problem is that twenty years of ever increasing complexity in mail handling has created concomitant complexity in sendmail. For system adminstrators, the sendmail configuration files are probably the most complicated things they have to understand and maintain.

The rub is that most sysadmins have many duties, and little time to thoroughly read the above book. What is needed is a crib sheet, that lets you quickly solve very common sendmail configuration issues. Wherein the need for this book. Hunt takes a pragmatic approach. He tells you enough to handle these common issues. Sometimes, this comes at a slight cost. For example, he never really fully explains the the sendmail class notation. For a rigorous explanation, you still need Allman's book. But as a practical matter, you probably not that curious about the notation anyway. Hunt's approach may solve your problems quicker!

An interesting aspect of this Cookbook is that it shows the recent evolution of sendmail, as seen in the subtitle at the top of the cover, "Spam-Fighting". Sysadmins who dealt with sendmail from 5 years ago or earlier will recall nothing pertaining to antispam techniques.

But just as email was the first killer application, the second killer application was the browser, starting in 1992-3. The third killer application was spam, often viewed via the second application. In the last 5 years, spam has grown amazingly. So much so that it has been debated on the floors of the US Parliament! It has gotten to the point that some alarmists are even claiming that this third killer app might be crippling the first app!

Well, this Cookbook has several sections, including an entire chapter, focussed on various antispam techniques, like procmail parsing, or hooking up to Real Time Block Lists like spamhaus.org. The efficacy of such methods may vary widely, but you do get a choice. Though none of these currently appear to offer a truly effective countermeasure. You are still getting tons of spam, aren't you?

Don't expect handholding in Cisco Routers for IP Routing as it explains the Internet Protocol (IP) suite and how to implement it with Cisco hardware and software. The key components needed to keep a network online are presented--addressing, subnetting, bridging, and routing--but this book assumes readers are generally familiar with the Cisco Internetwork Operating System (IOS) command-line environment, so it doesn't spend much time on the early familiarization process.

The bulk of each chapter contains practical information for setting up systems and solving problems, including lots of procedures and plenty of illustrative router output, plus insights on good design and administration practice. Readers will also find conceptual, hands-off material explaining what the various protocols do and how they do it.

Cisco Routers for IP Routing is rich in prose and presents complex topics with some fine conceptual diagrams. However, it explains only enough to help you understand the practical material that follows. For a really thorough understanding of IP concepts, supplement this manual with Thomas A. Maufer's more in-depth IP Fundamentals: What Everyone Needs to Know About Addressing & Routing. --David Wall

Book Description

Provides a complete systematic approach to network design, implementation, and troubleshooting with Cisco routers. Key technologies covered include Cisco Network Layer (OSI/RM), IP, IPX, Distance Vector Routing Protocols, Link State Routing Protocols, Multicast IP, and much more. Provides complete coverage of Cisco-specific troubleshooting tools including Cisco debug commands, traceroute, ping, and scripts.

Invaluable quick reference.......2002-12-22

I have read all the theory and lengthy samples from the CiscoPress books, now I need a quick reference to perform my day-to-day task as a Network Consultant. This book provided the quickest way to know the stuff in configuring Cisco Routers. This is a valuable book for those who plan to tackle the CCIE Lab exam.

Good enough to keep it as a reference........2002-11-21

The author did a great job of presenting the relatively basic information on IP routing as it applies to Cisco routers. You will find quite a few useful IOS commands discussed in the book that will want to keep it as a handy reference. I would also suggest looking into getting "Cisco IOS for IP Routing" by Andrew Colton. That book would take you deeper into mechanics of modern routing protocols (EIGRP, OSPF, IS-IS, BGP), along with a discussion of Cisco IOS commands.

Great For Filling In The Gaps, CCIE Prep.......2000-08-23

This book does an excellent job of calling small details to your attention that sometimes slide right by you when using larger books. Between this and Jeff Doyle's TCP/IP book, you'll be covered for the written exam and have a firm foundation for the lab. A must for your library and my compliments to the author!

Just Great.......2000-03-20

Why did this kind of book took so long to be published? The content is just what is missing in the Cisco Press publications, even better, this book is the first that offer a metodology for studying the Cisco stuff, generalizes the commands and make them easy to get along with them. The price is very reasonable and gives you better material in 474 pages than other with more than 500. If you are thinking about having a better understanding of the "Dark side of Cisco" take look at this an uncover them, they are unbelievably easy to understand with Rudenko.

Dont miss this book!.......1999-12-02

Ok. So you've got all the Cisco Press Books. And you think what good is one little black book going to make. This is one of the most practical books on Cisco so far. The other one written from a practical approach was a title by McGraw-Hill.

This book is a winner. The author literally packs so much information in so few pages! unbelievable.

This book covers almost everything : Bridging, Routing protocols, Frame-Relay, Redistribution etc.

Readers interested in achieving mastery of the Internet Protocol (IP) addressing system and its related protocols should consult the superior information provided in IP Fundamentals.

Author Thomas A. Maufer begins with a discussion of the IP numbering system, including excellent coverage of subnetting, supernetting, and the differences between IPv4 and IPv6. The author reveals the intricacies of variable-length subnet masking (VLSM) and classless inter-domain routing (CIDR) before addressing how IP operates in various infrastructures, including Ethernet, Point-to-Point Protocol (PPP), Token Ring, and Frame Relay. In his discussion of IP routing, the author shows how the two versions of Routing Information Protocol (RIPv1 and RIPv2) and Open Shortest Path First (OSPF) work, both independently and in heterogeneous routing environments.

Maufer strikes a commendable balance between thoroughness and practicality. He makes sure--through liberal use of examples--that you understand everything necessary to complete your job. But he also goes to extraordinary lengths to bolster your grasp of the IP suite; his chapters conclude with fact-rich endnotes, plus references to journal articles and standards documents. In this way, IP Fundamentals helps you surpass mere technical competence to become an IP addressing and routing expert. --David Wall

This will make it easier to understand the IP World........2001-06-10

I have passed several exam involving IP, Routing and Switching. I though I had a very good understanding of the concepts. After reading this book I found that what I knew only scratched the surface.

From the beginning of the book you get topics like IP and IP routing foundations, addressing, subnetting, VLSM, detailed breakdown of the first three layers of the OSI model, Ethernet technologies, token ring and FDDI, PPP and Frame Relay.

The author breaks down routing with RIP and OSPF very well and makes the concepts comprehensible for even the beginner level technician. Also he handles ICMP, 802.1q & p as well as first-rate coverage of DHCP.

The book seems very complete and the author makes sure to include the RFCs that correspond to the different section for the reference purposes. Overall this is one of the best books for IP subject matter.

Very good explanation of concepts. however poor editing.......2001-03-20

This otherwise excellent book is marred and riddled by moderate to serious typos. At times the typos almost makes the text incomprehensible.

If the reader is ready to put in the extra effort and patience to understand these troubled portions of the book, then what he gets is surely worth all the trouble.

The book is one of the best book on IP that I have ever read. It explains in very great details and with amazing simplicity the most cryptic details about CIDR, VLSM and other highly complex topics.

The Chapters are arranged very logically and it almost feels like a continous text. I have decided to give the book 4 stars although it deserves more than 5 stars. I would really advise the publishers to spend some more time on a book to ensure its correctness, before the send the book out to the press.

One last think which I feel is that this book does assumes certain previous knowledge of concepts like ARP and other basic concepts of IP, hence this book should be much more fun and usefull after a reading a primary book on TCP/IP like Douglas Comer or W.R. Stevens.

Ultimate Subnetting.......2001-02-01

This book is amazing. I purchased it to get a firm grasp on subnetting, and it did for me what no other resource was able to do. The informative chapters followed by real world exercises really made me understand the underlying reasons as to why sunbetting was necessary and how it could be applied in real world scenerios. I only gave this book a 4 because at some points the writing does get a bit wordy, reading more like a technical manual. But other than that, this book is a keeper!

Just what the title says..........2000-11-15

This book will definately show you everything you need to know about IP. It has been a truly valuable resource. If you are new to IP and Routing, however, you may want to read something a little more basic first. Without a basic understanding of IP concepts, this book may seem a little too complex. Excellent book to keep on the shelf though...you'll go back to it again and again.

What every Administrator Should know about IP.......2000-11-11

This book is what is says Fundamental. IF you work with IP or want to work with IP you should know what is in this book. I found the chapter on subnetting wonderfully enlightening. This book answered many of my questions I had about IP. I highly recommend this book.

Make use of your commute time.......2000-09-09

If you are like me, then you have a significant commute in addition to your normal work day. If you also happen to be studying for the CCNA test, then you should definitely get yourself a copy of this set of audio tapes, and listen to them in the car while you ride to work and back. These tapes (4 of them, lasting about 4 hours) cover all of the main points on the test. Topics parallel the CCNA Exam Cram book, and cross-references are offered when useful. The last tape of the set has a short topic review followed by 60 or so questions and answers that are typical of the CCNA 640-507 test.

Please note: do not expect this set of tapes to be the only material that you will need to pass the test. Cisco tests are significantly more difficult than any Novell or Microsoft test that you may have taken in the past. You will need to read and understand all of the material in the Interconnecting Cisco Network Devices (ICND) book, as well as all of the material in the Internetworking Technology Handbook to have any hope of passing. Think of this set of tapes as a good use of otherwise wasted time that you will spend in the car commuting to work. Used properly, these tapes are a valuable addition to your other study material.

Excellent companion to Exam Cram CCNA Book.......2000-03-27

This is a must have if your studying for the CCNA exam and work long hours. Great to use in the car or working out. The information helps reinforce what you already have learned and helps to tie in certain subjects that are vague. Great learning tool.
