Essential System Administration - E-book - Multi-format

Since its first printing in October 1991, Essential System Administration has been the definitive practical guide for Unix and Linux system administrators. The book talks about all the usual administrative tools that Unix and Linux provide-and also shows how to use those tools in smarter and more efficient ways. Author AEleen Frisch expands coverage of networking, electronic mail, security, and kernel configuration-topics of increasing importance to administrators.
It also includes coverage of services such as LDAP, PAM, DHCP, and DNS, and discussions of many important open source tools, including SSH, Cfengine, Amanda, RRDTool, and Cricket. The latest versions of all major Unix platforms, including Red Hat Linux 7.3 and SuSE Linux 8, Solaris 8 and 9, FreeBSD 4.6, AIX 5, HP-UX 11 and 11i, and Tru64 5.1, have been thoroughly reviewed and tested. You will find this book indispensable whether you are responsible for a large, shared computer system or a network of workstations, or you use a standalone Unix or Linux system and have found that the fine line between a user and an administrator has vanished.
And even if you aren't directly or solely responsible for system administration, you'll find that understanding important administrative functions will greatly increase your ability to use Unix effectively.
