Red Hat Enterprise Linux 5 Administration Unleashed Review

Red Hat Enterprise Linux 5 Administration Unleashed
Average Reviews:

(More customer reviews)
I have read about 3/4th of this book so far,most of it is mainly just review for me since the RHEL 5 release. I have noticed so far a few issues mainly with grammar, spelling, and multiple misguided instructions such as the PXE installation method, LDAP setup, and a few other minor things. Overall the book is my favorite linux related book since it gets right to the point and doesnt have all the boring history lessons about 15 years ago when service such and such was developed and how it is completely different etc etc. Any one who's read a linux related book knows what im talking about.
In regards to the misguided instructions, for instance the PXE setup. I have gone through the chapter about 5 times now and slowly stepped through the documentation as it explains but still have yet to be able to get the correct outcome.(a working PXE installation). I have previous experience with PXE so I was able to figure this out on my own with no issue but worry that some new admins to RHEL will have a hard time getting this particular method of installation setup. I'm unfortunetly human so I still may have gotten the steps down wrong and other may find that the instructions are infact correct. If so ... cool. :)

RHCE Red Hat Certified Engineer Linux Study Guide (Exam RH302) (Certification Press) Review

RHCE Red Hat Certified Engineer Linux Study Guide (Exam RH302) (Certification Press)

The Red Hat Certified Engineer is one of the most respected of the Linux certifications. Part of the reason is because of the difficulty of the exam. "Red Hat Certified Engineer Linux Study Guide, 4th Edition" covers all the points of the exam very well and includes the information you need to work with Red Hat in the real world. In addition to all the information you need to pass the exam, the book contains over 50 lab exercises and two complete RHCE exams and the entire book on CD. If you plan on taking the exam do the labs, don't just read over them.
Michael Jang has consistently produced high quality books and this is one of his best. The book is strongly slanted toward passing the exam, which is okay since that is exactly what it purports to be. Throughout the book there are short comments marked off from the rest of the test which points to tips for real world items (called "on the job") and tips for the exam (called "exam watch"). Each chapter ends with a short summary, a "two-minute drill", self-test questions, and lab questions. The "two-minute drill" is great for exam preparation the day of the exam since it is pretty much the type of thing that you would put on note cards for a quick review anyway.
This is real-life advice and is full or tips and troubleshooting problems. In the installation section it covers disk partitioning, swap space, bios limits, multiple controllers, and RAID. Some good solid advice and information about things like problems with a computer with both a SCSI drive controller and IDE drive controller in the same system. The installation troubleshooting section includes boot loaders, RAID, logical volumes, kickstart automated installation and pretty much everything you might run across. It even includes how to boot up into single user mode, a very important ability for some administrative tasks and gaining root level access (full access to everything) to the system. For some reason, although this is used in real-life for a lot of reasons, it seems to be left out of most books. They will tell you to switch to single user mode to fix a problem or gain root access, but don't tell you how to do it. This book tells you everything you need to know. It includes not only the graphical and utility methods to do things but also includes the information for how it changes the configuration. The information is so detailed that you can hand add the lines and/or configuration files and do it all by hand if you would prefer. This way you understand exactly what each item does and it is much easier to troubleshoot problems.
The authors have included everything you need to know to install, troubleshoot, and administer a real-world server - shell configuration, kernel information, automation, X Windows installation and configuration, GNOME and KDE desktops, Apache server including security and virtual hosts, Squid proxy server configuration, secure FTP server, mail services including SMTP, sendmail, postfix, POP, and IMAP, Samba installation and configuration, printing services, DNS, BIND, DHCP, LDAP client configuration, firewall policies, network address translation, and the Linux rescue environment are examples of the breadth of coverage.
It even includes how to work with the automounter, another item that is left out of most other books. The only error I found was on page 11, Table 1-2, where it has "First IDE drive = /dev/had" when it should be "/dev/hda". For that to be the only problem I found in a book of this size shows the care with which it was edited.
This is simply the best book I have seen if you want to become a general Linux "guru". Not only does it have everything you need to pass the exam, it has everything you need to install and administer a Linux network. There are better books available on specific areas of Linux, for example a single chapter on Apache obviously cannot compete with a 600 page book on Apache server. Then again, this the best book around if you want an understanding of Linux that is general enough to provide a complete overview of how Linux works in the real world and is also detailed enough to provide everything you need to get everything you want up and running. "Red Hat Certified Engineer Linux Study Guide, 4th Edition" gets the highest recommendation I can give.
