The composition of this booklet was originally started because the Computer Science department at Widener University was in desperate need of documentation describing the capabilities of this ``great new Internet link'' we obtained. It's since grown into an effort to acquaint the reader with much of what's currently available over the Internet. Aimed at the novice user, it attempts to remain operating system ``neutral''---little information herein is specific to Unix, VMS, or any other environment. This booklet will, hopefully, be usable by nearly anyone. The purpose of this booklet is two-fold: first, it's intended to serve as a reference piece, which someone can easily grab on the fly and look something up. Also, it forms a foundation from which people can explore the vast expanse of the Internet. Zen and the Art of the Internet doesn't spend a significant amount of time on any one point; rather, it provides enough for people to learn the specifics of what his or her local system offers. One warning is perhaps in order---this territory we are entering can become a fantastic time-sink. Hours can slip by, people can come and go, and you'll be locked into Cyberspace. Remember to do your work!

Whether you need a network of ten Linux PCs and a server or a datacenter with a few thousand Unix nodes, you need to know how to automate much of the installation, configuration, and standard system administration. Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer.Automating Linux and Unix System Administration, Second Editionis unique in its focus on how to make the system administrator's job easier and more efficient: instead of just managing the system administrator's time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully. Both new and seasoned professionals will profit from industry–leading insights into the automation process. System administrators will attain a thorough grasp of cfengine, kickstart, and shell scripting for automation. After reading all chapters and following all exercises in this book, the reader will be able to set up anything from a Linux datacenter to a small office network. What you'll learn See how to make changes on many UNIX and Linux hosts at once in a reliable and repeatable manner. Learn how to automate things correctly so you only have to do it once, by leveraging the authors' experience in setting up small, medium, and large networks. Set up a Linux datacenter or a network correctly. Explore handling real–world environments where not all hosts are configured alike via a case study of a fictional new datacenter buildout. Examine real–world examples for core infrastructure services (DNS, mail, monitoring, log analysis, security, cfengine, imaging) to build on in your environment. Understand core system administration best practices, which are a key part of how cfengine and automations deployments are outlined in the book. Learn how to make changes reversible, repeatable, and correct the first time through interaction with product/application stakeholders (programmers, product managers, customers, etc.). Who this book is for This book is for Linux system administrators who want to learn about the software and methodology to automate repetitive tasks-regardless of network or datacenter size-in one place. System managers will also find it much easier to think about network technology and automation projects if they read this book.

I run FreeBSD on my computers. A lot of my friends run Linux, or at least one of the distributions of it. Naturally, then, we agree that a Unix-style operating system is the right choice, but we disagree on which to use. It's been my impression that the BSD communit{y,ies}, in general, understand Linux far better than the Linux communit{y,ies} understand BSD. I have a few theories on why that is, but that's not really relevant. I think a lot of Linux people get turned off BSD because they don't really understand how and why it's put together. Thus, this rant; as a BSD person, I want to try to explain how BSD works in a way that Linux people can absorb. While there's overwhelming similarity between the operating systems in most cases, there are also a lot of differences. As you probe more into the differences, you find that they emerge from deep-seated disagreements. Some are disagreements over development methodology, some over deployment and usage, some about what's important, some about who's important, and some about which flavor of ice cream is superior. Just comparing the surface differences doesn't tell you anything; it's the deeper differences that both explain and justify why each group does things the way they do.

This book is about using Python to get jobs done on Windows. We hope by now you have heard of Python, the exciting object-oriented scripting language that is rapidly entering the programming mainstream. Although Python is perhaps better known on the Unix platform, it offers a superb degree of integration with the Windows environment. One of us, Mark Hammond, is responsible for many of Python's Windows extensions and has coauthored the Python COM support, both of which are major topics of this book. This book can thus be considered the definitive reference to date for Python on the Windows platform.

If you're one of the many Unix developers drawn to Mac OS X for its Unix core, you'll find yourself in surprisingly unfamiliar territory. Unix and Mac OS X are kissing cousins, but there are enough pitfalls and minefields in going from one to another that even a Unix guru can stumble, and most guides to Mac OS X are written for Mac aficionados. For a Unix developer, approaching Tiger from the Mac side is a bit like learning Russian by reading the Russian side of a Russian-English dictionary. Fortunately, O'Reilly has been the Unix authority for over 25 years, and in Mac OS X Tiger for Unix Geeks, that depth of understanding shows. This is the book for Mac command-line fans. Completely revised and updated to cover Mac OS X Tiger, this new edition helps you quickly and painlessly get acclimated with Tiger's familiar-yet foreign-Unix environment.
