Unix Systems Administration Handbook: Nemeth, Snyder, Seebass, Hein
Posted by Mark on December 14th, 2005
A coworkers turned me on to this book. He is an old school Unix admin from back when I was still grasping at DOS 3.2, so I tend to give him some credit. And you know what, he was right, this is an awesome book.
It covers Linux, Solaris, HP-UX, and FreeBSD. Topics include basic stuff like startup and shutdown, filesystems, user admin, security, kernel drivers and config, and networking. It also gets into more specific stuff like various servers (httpd, email, news, dns), printing, office politics, working with Windows, and intrusion detection and response.
Not to mention the authors have a great sense of humor, which is sorely lacking from most computer books today.
