Linux Enterprise Cluster: Build a Highly Available Cluster with Commodity Hardware and Free Software

Overview

Since operating systems are constantly changing to newer versions and various Service Packs are being released, practically every book has one common drawback—once it has been written, changes can only be made in the new edition (revised and corrected). While writing this book, I faced some difficult conditions—with respect to beta versions and Release Candidates of the Windows XP Professional and Home Edition operating systems.

This is my favorite site.

• http://www.registrysecrets.com/ This site focuses solely on the Windows NT registry. If you're an experienced Windows NT user, then you're probably familiar with the book "1001 Secrets for Windows NT Registry" by Tim Daniels (in my humble opinion, it's the same as a translator's dictionary for the administrator). You can always find reliable and up-to-date information concerning Windows NT registry at this site.

• http://www.microsoft.com/ This site is certainly well known to everyone, and it remains among the most reliable and informative sources of information concerning all Microsoft products, including, of course, Windows XP. Search the Knowledge Base, and perhaps you'll find the answers to your questions.

They bridge the gap between native disaster recovery tools, which have limited functionality, and full network backups, which can take hours to retrieve and restore. These utilities are not shareware, but you can download trial versions.

• http://www.radium.ncsc.mil/tpep/library/rainbow/ This is the "Rainbow Series". In my modest opinion, it doesn't require any comments.
