Jason Eckert, "Linux+ 2005 In Depth" (repost)

Complete with extensive end-of-chapter review questions, hands-on projects and exercises, "Linux+ 2005 In Depth" serves as a practical guide that maps completely to CompTIA's 2005 Linux+ certification objectives and is designed to prepare you to successfully pass the exam. The topics introduced in this book - and covered in the certification exam -are geared toward systems administration; however, they are also ideal if you plan to use or develop programs for Linux systems.
