LPI Linux Certification in a Nutshell (In a Nutshell (O'Reilly)) Review

LPI Linux Certification in a Nutshell (In a Nutshell (O'Reilly))

The first thing I want to say about reading this book is : I passed! Certification books serve four purposes: first, they serve as a way to prepare for computerized certification exams. Second, they provide a 'training plan' for learning the objectives in the certification. Third, can a book explain system administration concepts while limiting a reader's exposure to difficult, elusive topics until later? Fourth, can a book like this still be useful post-certification?
Part One (covering the 101 test) contained generous amounts of examples for text-processing commands and a really top notch discussion of permissions, ownership, booting and documentation. Helpfully, 'need to know' boxes are scattered throughout the book to indicate how important a topic is on the test. Frequently, the author will point out that although he explained a certain topic in depth, it won't be covered in depth on the test. I really appreciated that, although I found that the actual test covered certain topics (such as X Windows) in much more depth than Dean leads us to believe. One thing, by the way, to remember, is that often the book gives only the 5 or 6 most popular switches for each command. If you learned about these commands only from this book, you might be overlooking some important switches. I found this especially to be true when Dean discussed user management. I consider usermod 'g and usermod 'G to be really important commands, but this book didn't even mention them. On the other hand, Dean gave an explanation of regular expressions which was quite adequate for the purposes of this book. Although omitting some switches proved exasperating at times, the simplified view of the commands can be helpful for linux newbies.
Part Two (covering 102 test) covered a lot more ground: Apache, sendmail, nfs, dns, tcp-ip; heck, books have been written on each of those topics. The book covered well these topics in particular: compiling a kernel, troubleshooting tcp-ip and using rpm's. I found his discussion of Debian package management to be hard to follow, although that may be because I've never used it before in real life (but watch out! The test covers this in depth!). The book's discussion of network services (nfs, sendmail, apache, samba) was shallow at best, but I doubt anyone would rely on such a book for maintaining a web server, for example. But it provided some of the basics at least. The section on X Window was succinct and helpful. Also, some of the information presented is outdated, at least on Red Hat's latest distribution. Red Hat, for example, no longer uses inetd for startup, and some of the directory paths have since changed. These are minor quibbles, and one of the challenge of passing a certification like this is asking yourself: should I be learning things for the exam that are no longer accurate or relevant in current distributions? Certifications test the knowledge available at the time of test creation, when in reality new applications are being added and processes streamlined every day.
The book contains lots of sample multiple choice items, review questions and exercises. The multiple choice items didn't really add much to the book, but I frequently referred to the review questions. (Remember, the LPI exam has fill-in-the-blanks questions). Don't overlook the excellent 'highlighter's index' at the back of the book.
Two minor quibbles. First, the cover is not very strong and is bent, torn and curled over. The other is that the LPI exam objectives are not located at the front or back of the book. Rather, the table of objectives for 101 are in the front, and objectives for 102 are in the middle. I referred to this table constantly to see the amount of weight LPI was giving to a particular topic. Also, because the table of contents follow the LPI learning objectives (probably a smart thing), it is often difficult to find documentation about a certain command. For that I might recommend Linux in a Nutshell , 3rd Edition, which serves as a comprehensive index of commands and system utilities. It is excellent. Also, General Linux I Exam Prep (Exam: 101) by Dee Ann LeBlanc (published in 2000), is an extremely helpful book (and available for significantly reduced price used). Although it was one of the first to market and didn't address the LPI objectives explicitly, the exercises and presentation of material are every bit as good as Dean's book. Keep in mind also that LPI Linux Certification is not sufficient in and of itself. You will probably end up referring to other books such as Matt Welsh's Running Linux, Olaf Kirch's Linux Network Administrator's Guide or the unbelievably good Rute User's Tutorial and Exposition .

CompTIA Linux+ Complete Study Guide: Exams LX0-101 and LX0-102 Review

CompTIA Linux+ Complete Study Guide: Exams LX0-101 and LX0-102

I bought this book on Amazon when it came out a few months ago. I have the older Linux+ book (for the previous version of the Linux+ exam) but that version of CompTIA Linux+ is ending as of Oct 31 2010 (it consisted of a single 90 question exam - equiv of 6 months of Linux experience). So I was undecided on what exactly I should do: A.) Push it and take the existing test before Oct 31 2010 or B.) Just take the new Linux+ exam (actually two tests) powered by LPI. Since I had heard that the LPI version is much more comprehensive, I figured I'd go that route. Well let me tell you this book and from what I can surmise the new exam as well, is no joke. This book is way more in-depth and detailed than the previous Linux+ books. It is now recommended by CompTIA that you first achieve your A+ and your Network+ certification, as well as have 1 year of Linux admin level experience before attempting Linux+. If you want a taste of what this study book is like the very first chapter starts out with listing commands and explaining regular expressions. I've been working with Linux for some time so this was not a problem for me but if you haven't used Linux before you might want to brush up on your basics before you consider this one... The older books started out explaining what Linux was and what GNU licensing was about, etc (intro type stuff).
I have not taken the exams yet but I will report on how well I do after..
