4.0 out of 5 stars A very good book with a few mistakes
I've over 14 yrs. Linux sys-admin experience and decided to take the exam. So, bought this book to prepare for RHSCA/RHCE exam and found it's very good as study material and also as reference. It seems to be a must-have one for the RHSCA/RHCE candidate, even for a experienced one. However, the included PDF version is bit different form the original book for a few...

This review is from: RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press) (Paperback)
Just so you know where I'm coming from, RHEL4/5 admin with 5 years experience and plenty of prior experience across other OS's, not a sysadmin God, but not too shabby, looking to fill a few blanks like selinux that just haven't come up in the working world.

Bought this to help fill in a few blanks before the exam, but unfortunately found it rather rambling and unclear, inaccurate in places, and frankly feels like it has been rushed to market without proper editing or proof reading. For example, the chapter 'The Boot Process' is not the place I'd expect to find details of ifconfig, network configuration and ntp. It frequently doesn't expand on acronyms (pretty standard practice in any technical documentation in my experience the first time you mention something), for instance 'MLS' (Multi Level Security) in relation to SELINUX is not expanded at any point, leading to frequent visits to the web to clarify points.

It lacks any insight into what is happening under the bonnet, which as an engineer I find unhelpful. How can such a clearly defined subject not have clearly defined chapters and some fundamental principles covered?

In short, it's too vague to be a reference, and too rambling to allow for study and I am now in need of something more focused.

I've over 14 yrs. Linux sys-admin experience and decided to take the exam. So, bought this book to prepare for RHSCA/RHCE exam and found it's very good as study material and also as reference. It seems to be a must-have one for the RHSCA/RHCE candidate, even for a experienced one. However, the included PDF version is bit different form the original book for a few chapters, and there quite a few serious ones. I haven't finished reading the book yet but beware of page 51, 06-ch06.pdf, where it describes how to auto-mount an encrypted LUKS filesystem - if you do that you'll end up with a non-bootable system. After adding the "/etc/fstab" entry (and of course before [re]booting), you need to put this in to the "/etc/crypttab":

< encrypted block device > < path/to/the/actual/device > < password OR none > [list of options]

So, if "/dev/mapper/test-crypt" is the name of the resulting encrypted block device and "/dev/sdb1" is the path to the actual device, the entry should be:

test-crypt /dev/sdb1 none

It'll ask for the LUKS password during boot. For the password less booting, you need to put the password in a file like this:

# touch /root/luks.key && chmod 600 /root/luks.key
# cryptsetup luksAddKey /dev/sdb1 /root/luks.key
# echo "test-crypt /dev/sdb1 /root/luks.key" > /etc/crypttab

(The path and the name of the key file could be anything of your choice but should be matched in every entry).
The "/etc/crypttab" is actually mentioned in the book, page 381, but with some what misleading information. "<directory name w/o slash>" is wrong interpretation, according to the man page.

2.0 out of 5 stars Confusing presentation, and some bits are just wrong, 3 Mar 2013
Verified Purchase(What is this?)
This review is from: RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press) (Paperback)
You need to read chapters One and Two at the same time to figure out what the lab system 'baseline' starting point is. It would help if there was an appendix that said 'Just build this, you will learn more about what it actually is later'.

Got to Chapter 3 and choked on this bit;
"
ln
Linked files allow users to edit the same file from different directories. When linked
files are devices, they may represent more common names, such as /dev/dvd. Linked
files can be hard or soft.
Hard links include a copy of the file.

As long as the hard link is made within the same partition, the inode numbers are identical.
You could delete a hard-linked file in one directory, and it would still exist in the other directory."

The above is just plain wrong!

A file is an entry in a directory that contains the name, and the inode number of the actual file.
Using the 'ln' command to make a hard link just creates a new entry in a directory pointing to the same inode as the file you are linking to. As each file system has a private set of inode numbers, you cannot hard link from one filesystem to another, but you
can use a symbolic link (-s) to achieve the same effect.

So a link is not just for editing, it is not a 'copy'. A hard link is where an entry in a directory points to the same inode as another entry in some other (or the same) directory, and you cannot have hardlinks from one filesystem to another (nothing to do with partitions!) as inodes are only unique within a file system.
When you delete a file, the actual function in the kernel is 'unlink'. When the number of hard links to a file is down to zero, the file is actually removed.

Looking for alternative source of training materials for RHCE exams...

3.0 out of 5 stars good exercise book, 13 Feb 2014
Verified Purchase(What is this?)
This review is from: RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press) (Paperback)
The book is good to practice for the exam and build a small lab, it is quite useful to get experience before the exam. The fact that the chapters are available as pdf is good because you can read things beforehand (bus, train) and then practice when you have time. The instructions sometimes are not quite detailed and can be a bit confusing to read sometimes. Perhaps it is target for beginners, I found the order of things too confusing sometimes. On the other hand, instructions weren't precise enough and, in this particular, actually targeting more experienced users. I haven't tried the last chapters for the RHCE.

A essential read to someone that is pursuing the rscsa or rhce certification .
Also even if you do not get the certification there are always good things to learn here .

3.0 out of 5 stars could be alot lighter if it stuck to the point, 18 Aug 2014

This review is from: RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press) (Paperback)
Although Michael Jangs book is well known for being the book to buy when doing your RHCE, I found it went over and over and over the same statements like a stuck record.
this book could be half its size (pages wise) if it just stuck to the subject matter and stopped going of on a mission.
I passed my rhcsa and rhce, but I cant say this book helped much. The redhat course books were far more useful.

2.0 out of 5 stars I also didn't like the style, 26 Nov 2013
Verified Purchase(What is this?)
This review is from: RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press) (Paperback)
On the plus side, the book includes practice exams, and a brief summary of the key skills/tasks expected early on. However, it's very long, can be confusing, contains a lot of superfluous or anecdotal comments and is at times inaccurate (nothing dangerous, but I would advise against using this book as your only point of reference).
If your looking for an introduction to Linux, which will get you through the RHCSA/RHCE qualifications, this is too short. If you are an experienced professional who just needs to fill a few gaps in your knowledge then it's far too long.
I also didn't like the style. It's quite a chatty book, with section headings like "Wow, look at all that software", which some people might like, but I didn't. It's also interspersed with slightly pointless and annoying 'factoids' (LILO hasn't been supported by RedHat for years, for example), and little detail about how each section actually relates to the exam.
The PDF copy is Ok, but it's just PDF - there isn't a HTML, ePub or mobi copy too.

The book is a must for those taking the RHCSA / RHCE exams but is a useful source of information even if you don't plan to take the exams.

I have read through the first 2 chapters of this book to get the baseline system set up and would say it is confusing to say the least. As one reader suggested there is a lot of "rambling" and not actually getting to the point. Not recommended.

I bought this book for the soul reason of studying for the exam, I am getting through chapter 2 at the moment as you do need a 64bit machine for this exam. It is very clear but it is not the best book to start with if you have not got previous experience in Linux or prior knowledge of networking.
