This text takes an in-depth look at the fundamentals of Unix system administration in a real-world, heterogeneous environment. Whether you are a beginner or an experienced administrator, you should quickly be able to apply its principles and advice to your everyday problems. The book approaches Unix system administration from the perspective of your job - the routine tasks and troubleshooting that make up your day. Whether you're dealing with frustrated users, convincing an uncomprehending management that you need new hardware, rebuilding the kernel, or simply adding new users, you should find this book helpful. It covers back up and restore and how to set up printers, secure your system, and perform many other system administration tasks. This second edition has been updated for all major Unix platforms, including SunOS 4.1, Solaris 2.4, AIX 4.1, Linux 1.1, Digital Unix, OSF/1, SCO Unix Version 3, HP/UX Versions 9 and 10, and IRIX Version 6. The book has been thoroughly reviewed and tested on all of the platforms covered. In addition, networking, electronic mail, security, and kernel configuration topics have been expanded substantially.
Topics covered include: starting up and shutting down your system; adding new users; managing processes; system security; organizing and planning file systems; planning and performing backups; setting up pointers; TCP/IP networking; setting up email; adding terminals and disk drives; and setting up and using the accounting system.
