Absolute FreeBSD The Complete Guide to FreeBSD 2nd Edition
Michael W. LucasWelcome to Absolute FreeBSD! This book is
a one-stop shop for system administrators
who want to build, configure, and manage
FreeBSD servers. It will also be useful for those folks
who want to run FreeBSD on their desktops, servers,
diskless system farms, and so on. By the time you finish
this book, you should be able to use FreeBSD to provide network services.
You should also understand how to manage, patch, and maintain your
FreeBSD systems and have a basic understanding of networking, system
security, and software management. We’ll discuss FreeBSD version 7, which
is the version recommended for production use at the time this book is
being released; however, most of this book applies to earlier and later
versions as well.
