| |
Intended for administrators proficient in Unix environments, this course helps administrators transition their Unix skills to the Linux environment. This accelerated fast track course concentrates on the popular Red Hat Enterprise Linux distribution, and covers subjects ranging from initial installation of Linux to day-to-day administrative tasks such as management of user accounts and disk space.
Also covered is setup and maintenance of many of the most popular network services available for Linux, including servers for DNS, SMB, e-mail servers, FTP, web, and caching proxy. Special attention is paid to the concepts needed to implement these services securely, and to the trouble-shooting skills which will be necessary for real-world administration of network and system services.
This course is intended to be taught as a five day 40 hour course. However the content supplied could span more than seven days in length. To keep the course within a targeted 40 hour time frame a consensus between the student and instructor must be made on which topics and labs not to cover. The remaining topics not targeted for exclusion should be covered at an accelerated pace. |
