Like any other multi-user system, UNIX requires some care and feeding. Essential System Administration tells you how. This book strips away the myth and confusion surrounding this important topic and provides a compact, manageable introduction to the tasks faced by anyone responsible for a UNIX system. We have organized it so that you can find what you need to know easily, without wading through pages of extraneous information.If you use a stand-alone UNIX system, whether it's a PC or a workstation, you know how much you need this book: on these systems the fine line between a user and an administrator has vanished. Either you're both or you're in trouble. If you routinely provide administrative support for a larger shared system or a network of workstations, you will find this book indispensable. Even if you aren't directly responsible for system administration, you will find that understanding basic administrative functions greatly increases your ability to use UNIX effectively.Topics covered include:
Starting your system and shutting it down.
Organizing and planning filesystems.
Adding new users.
Planning and performing backups.
Restoring lost files from a backup tape.
Setting up mail service.
Setting up a printer and the spooling system.
Setting up the accounting system.
Managing UNIX processes.
Adding new terminals and disk drives.
Covers all of the major versions of UNIX, including SunOS, XENIX, System V.3 and V.4, and AIX.
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects.
The animal featured on the cover of Essential System Administration is an armadillo. This insect-eating mammal is native to South America and has spread through the southern United States. Unlike most insectivores, the armadillo has teeth--rootless pegs set far back in its mouth. These teeth allow it to supplement its diet of termites, scorpions and other insects with snakes, poultry, fruit, and eggs.
The armadillos name, "little armored thing," was given to it by the Spanish when they invaded the New World. This "armor" is an outer layer consisting of numerous bony plates with a horny covering. This shell is hinged at the middle of the back, allowing the front and hind sections freedom of movement. In some species, this covering extends over the face and tail as well as the torso and limbs.
Armadillos range in size from the great armadillo, at 5 feet in length, to the fairy armadillo at 5 inches. The most common of the armadillos, the 9-banded armadillo, is about the size of a house cat.
UNIX and its attendant programs can be unruly beasts. Nutshell Handbooks(R) help you tame them.
Edie Freedman designed this cover and the entire UNIX bestiary that appears on other Nutshell Handbooks. The beasts themselves are adapted from 19th-century engravings from the Dover Pictorial Archive.
