Appendix B. Scripts and Utilities
This appendix contains a collection of scripts and utilities that I find useful when administering distributed systems. Many of the scripts are described, or at least mentioned, in this book. Each contains a brief description of its function. Although I have tested these scripts and utilities and use them on a regular basis, platforms and configurations differ, so be sure to test them in your own environment. These scripts and utilities are also available at the O’Reilly web site; see the Preface for details.
