Product Description
If you do systems administration work of any kind, you have to deal with the growing complexity of your environment and increasing demands on your time. Automating System Administration with Perl, Second Edition, not only offers you the right tools for your job, but also suggests the best way to approach specific problems and to securely automate recurring tasks.
Updated and expanded to cover the latest operating systems, technologies, and Perl modules, this edition of the "Otter Book" will help you:
- Manage user accounts
- Monitor filesystems and processes
- Work with configuration files in important formats such as XML and YAML
- Administer databases, including MySQL, MS-SQL, and Oracle with DBI
- Work with directory services like LDAP and Active Directory
- Script email protocols and spam control
- Effectively create, handle, and analyze log files
- Administer network name and configuration services, including NIS, DNS and DHCP
- Maintain, monitor, and map network services, using technologies and tools such as SNMP, nmap, libpcap, GraphViz and RRDtool
- Improve filesystem, process, and network security
This edition includes additional appendixes to get you up to speed on technologies such as XML/XPath, LDAP, SNMP, and SQL. With this book in hand and Perl in your toolbox, you can do more with less -- fewer resources, less effort, and far less hassle.

Format:Paperback
If you are someone who is:
* an active system administrator, and
* comfortable with Perl, and
* looking for ways to simplify your live by automating some tasks using Perl, and
* up for learning something new, and having some rather geeky fun while you're about it,
then this book could be right up your street.
You are assumed to be reasonably competent with the language: the
author says "if you know a little Perl, and you need to perform system
administration tasks, this is the book for you", but the code examples
do jump in at a realistic - though very comprehensible - level. The
code is presented with the assumption that the reader is comfortable
with the basics of objects, modules, anonymous hashes/arrays, slices,
use of 'map', regular expressions and references for example.
This book is reassuring from the first time you open it. It feels
reliable and trustworthy. We are told in the Preface that the code
samples are "use strict"-friendly, and the code examples are
comprehensible and thoroughly explained. I found the writing style
both authoritative and accessible. Every chapter ends with a list of
the CPAN modules used in the chapter (with version numbers) and a set
of references for further information, reinforcing the impression that
care has gone into the book.
Further, you get the impression that this guy knows what he is
doing. This is reinforced by the fact that this is a second edition,
and the first was ten years ago; the references to well-respected CPAN
Perl modules and their authors; and the general air of
professionalism.
The book includes a collection of highly useful 'N Minute
Tutorial' Appendices on XML, XPath, LDAP, SQL, RCS, 'VBScript to
Perl', and SNMP.
The final chapter, with its subtext "Remember to play", is a
delightful celebration of why sytem administrators enjoy their
job. Let's make a time-line out of our crontab! Let's geocode the IP
addresses in our server logs! Just because we can! (And, which is the
point of the chapter: let's see what we can learn from it!)
Any active and Perl-literate system administrator should find this
book stimulating and rewarding, and be able to take things from it
that they can apply to their work.

The Otter Book never leaves my side
21 Oct 2009
Format:Paperback|Amazon Verified Purchase
Perl occupies the sweet spot between shell scripting and C programming, with the ability to lean as far as you'd like in either direction. As a sysadmin, Perl is better than a tool -- its the perfect tool for building tools, and this book is at the top of a very short list of texts which help bring to bear the full power of the best language for cutting down complex tasks down to size.
I've read a lot of Perl books and I own most of the O'Reilly books on the topic. The Otter Book, however, is the one which I cart around with me in my laptop bag wherever I go and is the first place I look for hints on how to attack problems that I face at work or home. It's chocked full of working examples and hints and tips on how to customize them, as well as plenty of context as to why these suggestions work the way they do.
The book is very well written and I highly recommend it to anyone, whether they are a professional admin or just want to cut out some of the repetitive tasks of managing their own workstation.

Yes it's all online ... BUT!
11 Aug 2009
Format:Paperback
On times I think that having books on Unix or current computing topics in general is an oddity at best. Isn't all the information we need readily available via Google, some blogs and for Perl CPAN? But then again as I was reviewing the second installment of Davids Otter book I found my self quite often amazed at all the little gotchas and tricks David added in. There are so many tools available today that this book severs as an invaluable guide through the jungle of possibilities in doing efficient System Administration. David does not praise a single solution to all problems. He rather gives detailed advice on succeeding in various scenarios. Yes the book is also about doing sysadmining with perl, but it comes natural and is in no way a language advocacy piece on the finer points of perl programming. It is both wide and deep by providing detailed examples in actual working code. I can highly recommend this book for both seasoned as well aspiring master craftsmen.
