Kurzbeschreibung
Automating UNIX and Linux Administration will focus on automating the tedious daily tasks of system administration. It will provide real-world examples and explore the existing tools that will help with this task. Although the book will provide brief overviews of tools and technologies that are covered, the author will assume the reader knows how to edit a configuration file or mount a file system. The book will focus on putting these tools to use in the real world, such as how to use a set of Perl scripts to manage your user accounts across 1000 machines. It will not show you how to write a basic "Hello World" program in Perl nor contain a Perl function reference or summary. The techniques, methods and tools covered in this book will help on a single system, but will be much more useful across multiple systems. Whether you are managing 2 or 5,000 systems, whether they are desktops, servers, or a Beowulf cluster, you will benefit from this type of automation. Although some of the book will be Linux-specific, most of it will apply to any UNIX system. The book will also focus on automating tasks across multiple variants of UNIX.7Covers tasks the administrator will most want to automate7Provides multiple solutions to each task7Focuses on reliability, efficiency, and security7In-depth coverage of numerous automation tools and analyzes the efficiency of each depending on the task at hand
Synopsis
Wouldn't you like to automate the tedious daily tasks of system administration? Automating UNIX and Linux Administration will show you how, by exploring existing tools and offering real-world examples. Although some of the book is Linux-specific, most of the information applies to any UNIX system, including material on automating tasks across multiple variants of UNIX. Author Kirk Bauer briefly overviews tools and technologies--and assumes preliminary knowledge about editing a configuration file or mounting a file system. The techniques, methods, and tools in this book will help you manage a single system--but will prove especially powerful across multiple systems. No matter if the systems are desktops, servers, or Beowulf clusters--all of them will benefit from this automation. And managing five to five thousand systems will become a simpler task!

Another must-have reference for unix admins!
26. September 2003
Format:Taschenbuch|Von Amazon bestätigter Kauf
Hot off the presses: I just received this book from Amazon yesterday. So far I've only read the introduction and the chapter on ssh and skimmed through the rest and it's fantastic! I'm not sure how much new stuff I expected when I ordered it, but it's already exceeding my expectations. I'm already finding out things I didn't never realized about ssh, and the side commentary on different ways of using ssh within scripts to administer across multiple machines is just sublime.
The author looks way beyond just slapping together some scripts to automate routine tasks, and presents some professional and robust approaches for automation, covering single machine administration, multiple machine and cluster administration, push/pull approaches, automation script propagation, automation dependencies, automated error state identification and correction, installation configuration, automating backup and recovery, and security. (Lots of discussion on security throughout -- it's clearly written for the real world.) Throughout, the author demonstrates nuances to each of these problems that show real thoughtfulness and mastery and teaches how to approach these issues equally thoughtfully and professionally yourself, rather than just offering a cookbook of scripts on different topics.
It's got me thinking about all the routine crud I do in totally new ways already. I already know I need to go back and re-read it slower to process it (and in front of a keyboard to try stuff out). This is definitely a book that will be on my "ready reference" shelf for a long time to come.

Automation for larger networks
12. Dezember 2004
Format:Taschenbuch
I see that most of the reviewers didn't like this as much as I did. That may be because they are home users or have small networks - I think this is very useful for the admins of larger systems (though it may not be useful for VERY large systems).
Or it may be that the subject matter is too dry. Sure, this can be a boring subject, but isn't that the point? System administration is often boring, and particularly so if you haven't automated it. Making global changes isn't exciting, but it is something some of us have to do now and then.
I'm surprised that it averages two stars - I think it is better than that. When I first get a technical book, I flip to a few random pages - I'm looking to see if I find things I didn't already know and if things are well explained. I found a LOT of things I was not previously aware of and I thought the coverage was thorough.
I agree that it has a strong Linux slant, but I don't see that as a problem - most of what this book suggests could be translated to any system.

Average tech book for the Linux crowd - not Unix crowd
17. Mai 2004
Format:Taschenbuch
If what you want is a bok that's a cross platform as the title suggests, this might not be a book worth buying. Examples in this book make horrible assumptions, along the lines of removing all native commands and replacing them with GNU commands. In a Linux only environment, this may not be a problem. In many other environments where enterprise level support isn't a concern, this may also be acceptable. But the place where automation is needed the most is the larget enterprise production environments. While ideas and basic tennets outlined in this book are what you ultimately need, the scope of the examples have problems scaling beyond 20-100 systems, let alone 5,000+. As for the basic tennets, you can cheat and be reminded what they are: common configurations, keep good documentation as to the differences, and manage systems, in a secure manner, in a common fashion that relies on the common configuration and documented differences.
The errors and ommissions in this book should be easily caught by any technical senior administrator of the OSes in question. For me, that's Solaris and Linux.
For a Linux only environment, it is a solid book. The writing style is drier than most of the manuals I read from various Unix/Linux vendors, and truly is the first tech publication since I supported PBX systems to put me to sleep.
As for the "subjective" analysis of various tools to assist in automation, I was highly disappointed. On various occasions, only 2 or 3 tools were discussed in an attempt to make the assesments fair. In each case, I came up with twice as many tools that I use on a regular basis, that were also F/OSS (as was usually the criteria the author used to talk about a product) that perform similar, if not identical, tasks much better. And those tools aren't that new: most predate the tools he refers to. Plus, most Linux distributions come with them installed and configured by default!
Since all I got out of the book were the above tennets that I already have known for the past 10+ years, I was VERY disappointed. Just make sure you know who you're letting borrow your copy, and what is expected that they'll take away, otherwise you'll end up with junior admins scripting their way into destroying your enterprise.
