Students need to know more than just what command to type to become a successful system administrator. This unique book discusses the fundamentals of the craft, and how to think about the problems that are posed. Through real-world examples the authors discuss the models that experienced system and network administrators use, but rarely document. From a series of philosophical and practical points, the authors, in mentor-like fashion, build a set of larger guides and teach how to think like an experienced system administrator. The "What To Do When" section is of immense utility when students grapple with the many-sided issues faced in system and network administration. Students gain an understanding of the role and responsibilities of the profession and learn the technical skills that are critical to the success of a system and network administrator.
