Solaris 8 Advanced System Administrator's Guide, Third Edition is the perfect hands-on tutorial and quick reference for experienced Solaris 8 system administration. World-renowned Solaris expert Janice Winsor provides indispensable tips, advice, and quick-reference tables for these essential aspects of system administration: mail services, NIS+, Automounter services, the Service Access Facility, software installation and removal, shell programming, system security, and volume management. Thoroughly revised to reflect the latest Solaris 8 features, this book targets the tasks experienced system administrators find most challenging. Winsor begins by introducing Solaris mail services: their components and behavior, and how to plan and customize sendmail. Next, she introduces the NIS+ nameservice environment, showing how to configure both NIS+ Servers and Clients. The book includes a completely new chapter on WebNFS: how it works, and how to configure and utilize it. You'll learn how to set up new Service Access Facility services for terminals, modems, and printers; how to administer and patch software; and much more.
The book also includes in-depth coverage of security, including Authentication, the Automated Security Enhancement Tool (ASET), and Role-Based Access Control (RBAC), which allows administrators to assign partial superuser privileges to users as needed.
