<u>This course is the second in a series of courses about Linux technologies:</u>

:* ULI101 taught you to be a Linux ''user''. '''In OPS235, you will move from being Linux a ''user'' to being a Linux system ''administrator''.'''

:* As a system administrator, you will be responsible for '''installing, configuring, adjusting, maintaining, and troubleshooting the operation of computer systems'''. This is a lot of responsibility, and with that responsibility comes power. You will be able to change anything on the system, and you will also have the ability to damage or destroy the system.

:* In this course you use a '''removable disk tray an external SSD drive (USB 3) with the lab computers''' to set up a Linux system. You will also set up '''at least four additional Linux systems using "Virtual Machines"''', and therefore gain experience with different types of system configurations as well as setting up networking between systems.

:* Later courses (OPS335 and OPS435) teach you to administer Linux servers (web servers, DNS servers, FTP servers, file sharing servers) -- and to use more complex scripting to boost your system administration efficiency.

<u>Requirements for Success: :* '''It is very important to stay up-to-date with the coursework''', and to practice until you have confidently mastered each task. :* '''All of the software used in this course is ''open source'' software, so you are free to use, modify, and redistribute it'''. This means that you can install it as many times as you want on as many different computers as you would like. It also means that you can tinker with it -- you can take it apart, see how it works, and put it back together in the same or a different way, limited only by your time and ambition. '''You are encouraged to experiment and question liberally'''. :* '''The notes that you make during the labs and assignments are your reference material for the quizzes, tests, and assignments'''. Take really good notes, and if you have questions, experiment and consult with your professor. :* '''Carefully read ALL lab instructions and check your work regularly'''. The labs have been designed with backup safeguards to prevent the student from losing their work. On the other hand, '''students may lose their work if they fail to follow lab instructions or accidentally forget their removable hard disks in the workstation's hard disk bay drive!'''</u>
