Hein, Ben Whaley, Dan Mackin, 2017-09-14 “As an author, editor, and publisher, I never paid much attention to the competition—except in a few cases. This is one of those cases. The UNIX System Administration Handbook is one of the few books we ever measured ourselves against.” —Tim O’Reilly, founder of O’Reilly Media “This edition is for those whose systems live in the cloud or in virtualized data centers; those whose administrative work largely takes the form of automation and configuration source code; those who collaborate closely with developers, network engineers, compliance officers, and all the other worker bees who inhabit the modern hive.” —Paul Vixie, Internet Hall of Fame-recognized innovator and founder of ISC and Farsight Security “This book is fun and functional as a desktop reference. If you use UNIX and Linux systems, you need this book in your short-reach library. It covers a bit of the systems’ history but doesn’t bloviate. It’s just straight-forward information delivered in a colorful and memorable fashion.” —Jason A.

  unix system administration guide: The Linux System Administrator's Guide Lars Wirzenius, Joanna Oja, Stephen Stafford, Alex Weeks, 2007-06-03 The Linux System Administrator's Guide describes the system administration aspects of using Linux. It is intended for people who know next to nothing about system administration (those saying ``what is it?''), but who have already mastered at least the basics of normal usage. This manual doesn't tell you how to install Linux; that is described in the Installation and Getting Started document. See below for more information about Linux manuals. System administration covers all the things that you have to do to keep a computer system in usable order. It includes things like backing up files (and restoring them if necessary), installing new programs, creating accounts for users (and deleting them when no longer needed), making certain that the file system is not corrupted, and so on. The structure of this manual is such that many of the chapters should be usable independently, so if you need information about backups, for example, you can read just that chapter.

  unix system administration guide: Perl for System Administration David N. Blank-Edelman, 2000 Some people plan to become administrators. The rest of us are thrust into it: we are webmasters, hobbyists, or just the default technical people on staff who are expected to keep things running. After some stumbling around repeating the same steps over and over again (and occasionally paying the price when we forget one), we realize that we must automate these tasks, or suffer endless frustration. Thus enters Perl.The Perl programming language is ideal for writing quick yet powerful scripts that automate many administrative tasks. It's modular, it's powerful, and it's perfect for managing systems and services on many platforms.Perl for System Administration is designed for all levels of administrators--from hobbyists to card-carrying SAGE members--sysadmins on multi-platform sites. Written for several different platforms (Unix, Windows NT, and Mac OS), it's a guide to the pockets of administration where Perl can be most useful for sites large and small, including: Filesystem management User administration with a dash of XML DNS and other network name services Database administration using DBI and ODBC Directory services and frameworks like LDAP and ADSI Using email for system administration Working with log files of all kinds Each chapter concentrates on a single administrative area, discusses the possible pitfalls, and then shows how Perl comes to the rescue. Along the way we encounter interesting Perl features and tricks, with many extended examples and complete programs. The scripts included in the book can simply be used as written or with minimal adaptation. But it's likely that readers will also get a taste of what Perl can do, and start extending those scripts for tasks that we haven't dreamed of.Perl for System Adminstration doesn't attempt to teach the Perl language, but it is an excellent introduction to the power and flexibility of Perl, and it whets the appetite to learn more. It's for anyone who needs to use Perl for system administration and needs to hit the ground running.
