Linux Books

I just finished going through the entire book line by line. I am extreemly new to Linux and security, and this book made it all very clear. I only wish I realized that there was a second edition out when I bought this one. Everything in this original edition was still completely correct and appropriate, three years later.

I'm a big fan of the Hacking Exposed style of writing. All offensive theory is backed up by command line examples, followed by defensive countermeasures. Hacking Exposed: Linux, 2nd Ed (HE:L2E) follows this tradition, updating the content of the first edition and adding 200 pages of new content. Although I reviewed the first edition in Sep 01, reading the second edition reminded me of the challenges posed by securely configuring and deploying Linux systems.

The best way to learn while reading HE:L2E is to try the sample commands. I also recommend visiting the links mentioned and installing many of the tools described by the authors. I found programs like raccess, nsat (ch. 3), sslsniff (ch. 7), nstx, and httptunnel (ch. 15) particularly interesting from an attacker's point of view. From a system administration standpoint, coverage of passlogd (ch. 2), lilo and grub (ch. 5), and X (ch. 6) were very helpful.

The authors share many novel ways to abuse Linux systems, but counter those exploits with little-known features or third-party tools. I never knew I could use bash's HISTCONTROL feature to selectively remove entries from shell history files. HE:L2E goes the extra mile to help secure your system, such as including sample C code in ch. 13 to allow one to compile TCP Wrappers support into one's own programs. Other clear, concise defensive measures were introduced in excellent chapters on keeping the kernel and packages current (appendix B) and pro-active security measures (ch. 2). The last appendix gives a short yet powerful description of the damage an intruder can perform, showing how he hid unauthorized programs and how those programs were discovered.

If you use Linux, you'll find HE:L2E indispensable. I even applied many of the tools and techniques to my FreeBSD system, showing that that good security advice can be a cross-platform endeavor.

The Hacking Exposed books have set the bar for this genre of security book. Hacking Linux Exposed - 2nd Edition doesn't fail in meeting that bar as well. If you've read Hacking Exposed - 4th Edition and think this book can't tell you anything you don't already know- think again. For those who administer Linux boxes this book provides an in-depth look at specific hacks and vulnerabilities unique to the Linux operating system and the accompanying fixes and workarounds to protect yourself. The book is overflowing with examples and sample commands that users can immediately put to use to better understand the risks and how to mitigate them. Hacking Exposed is a must-read for security- this book is a must-read for Linux security.

First, this book does _NOT_ have a installation walk through...YES!!!

You will not find another book this comprehensive in the length in HLE has accomplished. i found the book to be on point, and not overdrawn on any specific topic. The authors usage of gender is something of a mystery aswell. For the first 10 chapters or so the cracker is a woman, then in later chapters it becomes a man, then in even later chapters a woman, then back to a man :-).

i found the book to be very well written, it feels like a very good naration. There is only a few plugs of direct humor (1 about using word for the publisher, another about the shortest sentence using all letters) but these few are lightening.

Technically this book is sound. it does very good in keeping the basics of security alive through the book (chattr +i, only use what you need, upgrade, etc...). This is very helpful to a beginer for reinforced learning. The software packages it mentions for firewalls, logging, etc. are very nice and descriptive.

All around great book. BTW, did i mention that is does _NOT_ cover a Linux installation from CD/DVD? That alone should be enough to buy it.

When I first starting using Linux systems and putting them online I had NO idea what sort of grief I was in for. The reason for that grief: I had NO clue how to 'harden' a system or what that term even meant. By not knowing that I put up systems that were quickly exploited by script kiddies and SPAM houses looking for open relays to use for SPAM and for 'zombies' to use in Distributed Denial of Service (DDoS) attacks. I bought this book, read it, and haven't had those problems since. If you are going to do *anything* with Linux on the internet then GET THIS BOOK NOW. Unless, of course, you *want* to have your computers destroyed on a weekly basis...

The Best series of books to learn Network programming from. The BEST in the world. Nothing comes close.

If you are reading this review you probably are looking for a comprehensive text on socket programming. Look no further. This is the One. You can stop reading reviews trying to find the perfect one and go hit the Add To Shopping Cart button with confidence. Detailed, comprehensive and clear. A favorite.

This book consists of "in the trenches" information Mr. Stevens learned over the years by reading source, testing thoroughly, documenting extensively, and assembling carefully all this data into one heck of a book on Unix programming. I feel certain in declaring that many who've developed code on Unix know instantly of Stevens' works. This update to his book appears just as thorough.

I do agree with a previous reviewer who was unhappy with the code samples' dependency on a header file in the back of the book. It's a clumsy technique, but it's difficult to imagine another way to accomplish the goals of including the header.

This book is excellent. I had previously bought "Advanced Programming in the UNIX Environment" by the same author and I loved it so now that I have to do network programming in Linux I got a copy of UNP. The book is well organized and has a lot more information than I expected (Raw sockets, Packet capture, IPv6 etc). Everything is explained clearly and with a lot of examples. It's a shame that the author passed away because I would buy any other book he wrote. Buy this book, it's expensive but It's so professional that is a "must have" for anyone that's going to be programming network applications in UNIX systems.

Thank you, Richard Stevens. Rest in Peace.

The book contains everything that I want to know about the Unix Sockets API. The book is well structured, and the explanations are generally good. I would give it 4½ stars if it was possible.

I do have a few minor gripes though. The text can be a bit dull compared to other books. I bought "Programming with POSIX(R) Threads" by David R. Butenhof at the same time, and this book is much more entertaining while still factual and correct.

I dislike that all the examples in the book uses a special header defined in the Appendix. That makes it impossible to use snippets of code from the examples to make your own applications.

Easily the best book on Linux that I have ever read or bought. Also one of the best computer books overall that I have ever used. That is saying a lot given that I have many computer books on the full range of computer topics and given that I am very picky in what I buy. The other reviews - all but one 5-star - give details on the book. I highly recommend it to anyone who wants to set up a Linux system or who has an interest in learning about Linux.

In regard to Linux in general, it provides a superior platform to the Microsoft platforms. Also the add-on programs that are available - all of the most useful are included in any of the best-known distributions, such as Ubuntu or Red Hat/Fedora - are as good as (in the sense of user-friendly) as the comparable Windows programs and in many cases better.

What is interesting to me is that much of the Linux development occurs outside the USA. It is a great tribute to the huge Linux-oriented developer universe that those developers have developed such outstanding tools that are free of the exorbitant, monopoly-determined prices of Microsoft products. So I hereby thank you all for your fantastic contributions to computer technology. Without your programs we would all be prey to the monopoly pricing and less-than-optimal programs produced by Microsoft. Not to say that there is anything wrong with most Microsoft products, but thank god there are better products available and better yet that most are free of licensing cost and most are changeable because the source code is available.

It's been two years since I've purchased this book, and I still reference it from time to time.

This book covers many common open-source applications used in conjunction with linux (bind,samba,sendmail,etc).

The examples are well-written. It's a great book for someone who is wanting to educate themselves to use linux.

I will note that the book seems to be red-hat/fedora biased. I use fedora, so that was a plus.

Much of what I have done piecing together information from Google is concisely done in this guide. This book got my mail server setup in no time whereas in the past I gave up in frustration (and lack of knowledge).

The mail chapter alone was worth the price but this book is full of solving common system administration tasks for people with some linux experience but not the expertise of being a sysadmin.

I really enjoy the content of the Book. Since my early days using Linux consult the linuxhomenetworking website for tips & howtos.

This is surely a must have book. It's been a while since I see some book with so much content !!!.

This certainly isn't a hand holding introduction to Linux by any means (jump in at the deep end, it works!). However if you're looking for a down to earth, practical guide to a variety of everyday tasks involved in running Linux in a server environment you'll find this book very useful. The subject matter covered is useful, and the explanations are sufficient with plenty of useful examples. Certainly a good introduction although obviously for the finer points of configuration more specialised sources will need to be consulted.

I had been working with Unix and Linux flavors for sometime, and this book has been a blessing for me. I need a book that was willing to detail every aspect of the OpenBSD ( at least the most relevant), kernel, workarounds, etc. And it does its job. Many Thanks,ed

I purchased this book from Amazon on March 4th, 2007. Two months and five days later, after two conversations with Amazon employees who assured me that I would receive the book, they still have not shipped it.

It appears that Amazon simply does not have the book. I phoned the publisher, No Starch Press, and they don't have a copy either. A PDF is available for download, but that's all.

At this writing, the Amazon listing still says that the book "usually" ships in one to two weeks. Amazon is apparently selling a product that it does not have to sell.

If you want this book, you might do better to buy one of the used ones.

So many computer books today are 800 pages of word bloat. Michael not only keeps the writing lively, but in K&R fashion, he gives a lot of information in a succint way. Highly recommended and an easy read. Also note, he gives a complete picture of openbsd from A-Z Not too tedious and not too broad. I have not found a linux book this nice.

I'm no security freak, but I love the OpenBSD concept: security above all. When I took a course in Unix operating systems, I was introduced to OpenBSD, and recommended to purchase this text. Albeit outdated (it covers version 3.2, and OpenBSD is now at 4.0), the book offers an overview of all the basics, including 3 whole chapters on the pf firewall.

Because of its general nature, the author, Lucas, does not solely focus on pf, but instead adds flair to an extremely hostile operating system environment. I don't recall ever working with a more difficult system from scratch. Lucas really helped in getting me through some of the more cryptic areas of installation and configuration. The book itself is quite basic, so if you need something specific, like a korn shell book, look elsewhere. His style also makes the book itself a fun read, I must admit, because of his colorful presentation.

I've had this book for more than a year now.

This may be the most fun textbook-with-no-pictures I've ever read.

Realy I bought the book, I didn't have any OpenBSD contact and I bought the OpenBSD CDs to try it and play, and the book arrived before the OpenBSD's CDs and I begun to read, and learned me how to install OpenBSD, When the CDs arrived realy was very easy to install and get my first steeps in this OS.

The GIMP is a powerful image manipulation package, provided under a free software license. It is very much the PhotoShop of the open source world. This book is an excellent introduction and tutorial to the GIMP's many powerful features. However, it is not intended to be a user manual. There is a separate and complete user manual for the GIMP available on the web. This book is also available on the web, and it is published under an open-source license - although cleverly they don't mention this in the paper copy itself. However useful it is to have the on-line copy, I cannot stress enough the quality and value in having a hard copy of this book.
Each chapter covers a different theme including layers, selections, masks, color spaces and blending, photo touchup and enhancement, compositing, rendering and web-based image production (including animated GIFs and imagemaps). The material is thoughtfully presented as a series of walkthrough examples.
The physical production of the book itself is very good. Every page is in full color and each chapter's start has a color flash at the edge of the page to allow you to easily locate it. The content has been equally well thought out. There is a very comprehensive index. At the end of each chapter is a list of FAQs correcting common misunderstandings about that chapter's subject. All diagrams are very clear and instructive.
My only gripe with the book is that there is no overview of the use of the standard toolbox of tools. I feel a simple explanation of how to use the various painting controls at the start of the book would have set the context for some of the later chapters on the image manipulation facilities of the GIMP, which indeed is the main thrust of the package.
It has been several years since a major book on the GIMP was published. What would be great would be a book that focuses more on programming and on plugins specifically - how to write them and a description of the ones currently in circulation. The next book set to be published on the GIMP, "Beginning GIMP: From Novice to Professional" is due to be released in April 2006. Until its arrival, this is still the only book on the GIMP worth reading.
For those of you interested in the vast amount of GIMP plug-in source code, just type "Koders Search GIMP" into Google. The first link in the resulting list is what you want. From there you can search through the folders and find the source for the many GIMP plug-ins.

I have read through a lot of this book and it has helped me tremendously in understanding the basic concepts and techniques for creating and manipulating digital images and graphics using the GIMP. Although it does not cover plug-ins in any great detail, it does lay a solid foundation for learning and using them in the future. Aside from that, almost every other conceivable topic is covered.

After I finish reading this book, I am confident that I will be able to read through (and understand) the many GIMP tutorials available online without difficulty. If you are looking for a good introduction to image manipulation and the GIMP, this book does not fail to deliver in any regard.

I have referenced the on-line version of this book several times and found several useful ideas and techniques out of it---especially those dealing with color correction and enhancement. However, there is no comparison to actually haveing physical pages to flip through and seeing the photos "in person". After reading through this book, several other Photoshop tutorials available make much more sense as well. My only complaint is that there is not much attention paid to any use of plugins or "advanced" clone tool techniques for repairing marred photographs without destroying the natural film grain etc. Also, some of the keybinding shortcust appear to have changed, and his examples using Layer masks did not always work for me as described in the book. Overall, though, purchasing this book is a great way to support open-source projects and learn a good deal about the Gimp as well.

I have searched high and low for a decent book on the Gimp. There are a several, good references ("Learning the Gimp in 24 Hours", "Essential Gimp for Web Developers", etc.) though many are out dated due to the rapid progress progress the developers. The Gimp, an excellent example of what open source cooperation produces, is well represented in this book. The author illustrates the use of the Gimp with clear diagrams, concise descriptions, and excellent examples of the Gimp's functionality. Apart from the official Gimp documentation, this book has served me well.

Exelent introduction to a complex subject. Still up-to-date as the fundementals apparently have not changed in 7 years. A few menus have changed slightly but I found this not a problem. This book appears to be out of print but you can download the HTML version and read it on your computer. You'll be trying out all the techniques while you read, so you just need an extra window for the text. I found the writing concise, the organization logical, and the examples helpful. You will find that the GIMP user manual also covers this material but does not really teach you what to do with it. It's not easy to learn--I've been doing photography for years so I thought I'd pick it up just fooling around with the software. It's not so easy!

This book is easy on Beginners. Load Linux to your machine and work on the examples. You will become good at it.

The format is good and you eat one bite at a time.

I found this book has some useful tricks that compensates for the chapters that maybe useless to someone who been using UNIX for sometime. This book made my life easier since I needed a book where I can get some of the useful Unix commands yet a little description with it to help me get by

I like easy to read book and I also assumed that learning UNIX is not necessarily has to a struggle. This book stood up to my expectations almost perfectly: it is very well written and clearly expressed work. It does not overwhelm with technical details and does not press too much. I followed an advise in some review and purchased Linux and UNIX for a beginner training suite, 4DVDs + 2CDs includes 4 Unix Academy Certifications ed.2008. These two nicely complement one another. You watch it and you read it. If you didn't catch it from the first try you watch it again and read it again. In two months I found myself confident to that extend that gave advises to our system administrator and he accepted them because there were subjects that he wasn't completely sure. It is a way to start.
I can't overstate how much I have learned from them. Don't be naive, though. You will have to learn and memorize many things. The fact of owning neither book nor DVD will not make you knowledgeable, but if you will work it trough, trust me, you will surprise many people around!

The book is a real help when you struggle with new operating system's commands and horrible command line syntax. I paired this book with "UNIX Essentials" DVD and can't be happier! Book shows conception the DVD shows complete workflow! WOW! That is really smooth learning.
The book is very well logically organized and easy to navigate and it is free from stupid repetitions that many other books have!

The book is easy to use and understand, good choice for beginners, but might be a bit wordy for advanced users.

Its structure is very similar to a reference book, runs along the UNIX commands in 17 chapters, and provides enough information and examples to their usage. It contains three appendices summarizing the UNIX files and directories, the UNIX commands and their flags. It contains no theoretic essays at all, so if you are interested in the inner working or philosophy of UNIX, this book is not for you.

I liked that it uses a color (red) to distinguish the commands and flags from the output. I was glad to find links to the related topics inside the book, but missed a bibliography. And I missed one or more full chapters paying attention to the most popular implementations such as Solaris, AIX.

I am a systems administrator professionally, but I have a need to know the inner workings of UNIX that only seems to be covered in programming books. Specifically relating to certain system calls and interprocess communication methods.

This author has forgotten more about UNIX than I will ever grasp. While this book is dedicated to programming applications in UNIX and understanding the operating system's function calls, I am finding it to be a very handy reference for advanced system administration as well. The book is worth the price just for the chapters on process communication, in my opinion.

I really like the author's writing style. He gets down to business and covers the material without adding a lot of needless fluff or by making the chapters overly wordy.

The book is designed to server as a reference and is well-indexed, which is refreshing to find these days. It's very easy to find a topic you need as not everyone will need the amount of depth covered by each chapter in full.

I wish there were more UNIX books out there like this one.

The book is good for beginners. All you need to know to get started with Unix/Linux programming.

I bought this book in order to get an overview on what primitives I have available on a unix system for doing system programming. I found the book to be very useful for that purpose.

I use it occasionally.

I also found my peers lending it from me again and again.

To summarize: useful.

What's more to say, the title say's it all... Buy it!

This is an exceptional introduction to Unix features that most people won't see in every-day programming. The feature that Rochkind starts with may be the most problematic: portability. There have historically been dozens of Unices (sp?), all slightly different from each other. Even today, there are a number of different implementations in use, with small but maddening incompatibilities between them. Rochkind not only addresses the more common ones, he shows the standards-based ways of dealing with their differences.

After that, Rochkind goes over read/write/open/close/ioctl again, dealing with [a]synchronous subtleties that can mean a 100x difference in performance, backed by code samples and timing measurements. The rest of the book deals with multi-process applications, including communication and distributed processing issues. That includes process groups, interprocess communication (with all its system-dependent weirdness), sockets, and signals.

This isn't for the beginner or for the kernel developer, but never meant to be for either. It is a good, readable introduction to protentially tricky parts of the Unix API. I recommend it strongly to anyone building their own library of Unix references.

This is the first of the O'Reilly books I have been disappointed in. I bought the book for one reason-- to find out how to restore a / and /usr file system off a remote tape drive. Unfortunately the book does not answer this question, all of its examples assume the server has a local tape drive attached. The authors spend their time touting freebie utilities at the expense of a thourough discussion of the backup and restore capabilities that come with the operating system.

This book is important for System Administrators and DBAs. The book is well-written and have discussed all the major UNIX flavors back and recovery. The author went further by discussing the Backup and Recovery of major databases on these UNIX operating systems.
I give 5 stars.

As a former Unix system administrator, this book proved invaluable to me. Backups are a dreaded responsibility for most as they are not glamorous, but when a backup is needed, the administrator can become a hero or out of a job very quickly depending on thier backups. The author provides some deep insight into the art of backups, drawing upon real world examples that provide insight into the recommendations. The authors quips on real world backup stories is worth the price alone as there is great knowledge to be gained from someone else's mistakes and failures. Truly a gem that should be on EVERY system administrators bookshelf.

Even though I was still very new to Linux/UNIX, this book was able to help me create a fully automated backup routine as well as how to restore from those backups. I found the book very easy to read and not at all dry.

This is *THE* Computer System backup book. It contains all the basics of why you want to backup computer systems, plus many of the real world experience details. It is written from a Unix perspective, but is still applicable to Windows and other non-Unix environments.

I've been using this book as a general guide for several years now. It was a book I watched work it's way through the O'Reilly system from first announcement to general release. I bought it when it first came out. I have not been disappointed in it.

Many people think of computer system backups as a dry old musty topic of interest to nobody in particular. But 9/11 showed how important good disaster recovery planning and procedures could be to a business.

Some of the specifics are now a little out of date, but not by leaps and bounds. It is still very good for its core reason for being - Backups. It is very much less out of date than other computer books on the market today.

I have been dealing with large-scale computer system backups and disaster recovery for large employers for years... and I still consult this book regularly to make sure have not missed anything important. It covers all the topics you need.

This is the best OS book i have evern seen, really deserve 5+ starts. It gives many design issues/ideas of real exist OSes which helped me greatly. If you are really interested in OS or do some creative design job, this book is a must see. It seems next edition of this book will be unleashed next February. But what i concern is next editon may be delayed, because there are really too much new things these years, Linux 2.6 ... And I hope next edition will have some introduction to Windows Kernel. I am a UNIX fan, but you see, Windows conquer the PC's desktop, it surely has some shining points. GREAT JOB, URESH VAHALIA. :)

If you need to learn different flavours of UNIX, this is an excellent book. This book is worth reading cover to cover.

I found this book to be extremely helpful in studying for my OS PhD prelims. It really lays out the issues and presents solutions taken by SVR4, BSD, Mach, and Solaris in a clear fashion. Excellent detail. The Mach stuff is great, but it looks like it was almost cut and paste from the research papers. This book isnt for novices. I recommend using the BSD4.4 book as well. Both books dont look at Windows at all (for obvious reasons), so a look at the Dinosaur book (Operating System Concepts) is helpful as well for the case studies. You should have a
clear understanding of OS after finishing this book.

A certain small and select set of books can be found in any serious programmer's library. "UNIX Internals" is one of those books.

I originally encountered "UNIX Internals" in my undergraduate operating systems class. At the time, I liked it, but I didn't really appreciate its full beauty until I re-read it with a few years of operating systems experience under my belt. I work as an operating systems programmer for a living, and whenever my knowledge needs brushing up, I go back to this book.

Uresh Vahalia does an excellent job of comparing and analyzing the approaches taken by different operating systems, rather than merely describing them. His deep understanding of the topic is what really sets this book apart. In addition, it is well written, conveniently organized, and thoroughly indexed. If you really want to understand operating systems, this is the perfect book for you.

As others have noted, this book is not for the beginner. You should probably have a minimum of three years of computer science experience before picking this book up.

A must have book for the serious about Unix Internals. The author tried hard to cover the common features among the different Unix flavors. This book is very suitable for someone who likes to read textbooks. It needs lots of concentration. However, it's an excellent book to read, and a good reference. The author follows more or less an academic approach.

If you are coming from mainframe DB2, this is the book for you. Phil Gunning does a great job of explaining the many parameters and settings that make up DB2 UDB. Explanations are clear and straight to the point. It helped me to understand the DB2 UDB architecture and to get up to speed quick.

This book has helped my get started on monitoring and tuning my databases. Coming from Sybase, I had no idea where to start. I picked up this book and it guided me through all the monitoring setups and provided a monitoring and tuning methodology -- along with recommendations. This stays on my desk and is very handy.

This book is really well organized. The section on logical and physical design was a good review for me. It reminded me how important a good design is to a successful database implementation. The SQL Tuning, Buffer pool tuning, and DB and DBM CFG tuning chapters have helped me take care of my problem databases and suboptimal SQL.

I found this book to be very useful in tuning SQL and bufferpools. I liked the chapter on Problem determination and the utilities section. All v8 utility enhancements are provided.

The chapters on Type-2 indexes and MDC really helped me better understand how type-2 indexes improve performance now I understand what a dimension is and how to identify good candidate dimensions. The chapter on buffer pool tuning and Sort along with the DBM and DB CFG tuning tips have helped get my boss off my back!This is a great book by a DB2 Consultant.
