Whether you use a standalone Unix system, routinely provide administrative support for a larger shared system, or just want an understanding of basic administrative functions, Essential System Administration is for you. This comprehensive and invaluable book combines the author's years of practical experience with technical expertise to help you manage Unix systems as productively and painlessly as possible.

This pocket reference brings together all the important Unix and Linux system administration information in a single compact volume. Not only are all of the important administrative commands covered, but this reference also includes the locations and formats of important configuration files (including both general system databases like the password and group files as well as the configuration files for major subsystems like DNS, DHCP and sendmail).

In addition, variations in command usage and file formats are included for the most important UNIX versions. When you get a new system running a different Unix operating system, all the information you need will already be at your fingertips. The book covers these Unix versions:

• Red Hat Linux 8.0 and SUSE Linux 8.1
• Solaris 8 and 9
• Free BSD 4.7
• AIX 5
• HP-UX 11
