== What <u>This Course course is About ==the second in a series of courses about Linux technologies</u>

This course is the second in :* ULI101 taught you to be a Linux ''user''. In OPS235, you will move from being Linux a ''user'' to being a series of courses about Linux technologies:system ''administrator''.

:* ULI101 taught As a system administrator, you to will be Linux ''users''responsible for installing, configuring, adjusting, maintaining, and troubleshooting the operation of computer systems. '''In OPS235This is a lot of responsibility, and with that responsibility comes power. You will be able to change anything on the system, and you will move from being a Linux ''user'' also have the ability to being a Linux damage or destroy the system ''administrator''.'''

:* As a system administrator, In this course you will be responsible for '''installing, configuring, adjusting, maintaining, and troubleshooting use an external SSD drive (USB 3) with the operation of computer systems'''. This is lab computers to set up a lot of responsibility, and with that responsibility comes powerLinux system. You will be able to change anything on the systemalso set up at least four additional Linux systems using "Virtual Machines", and you will also have the ability to damage or destroy the therefore gain experience with different types of systemconfigurations as well as setting up networking between systems.

:* In this course Later courses (OPS335 and OPS435) teach you use a '''removable disk pack with the lab computers''' to set up a administer Linux system. You will also set up '''four additional Linux systems using "Virtual Machines"'''servers (web servers, DNS servers, FTP servers, file sharing servers) -- and therefore gain experience with different types of to use more complex scripting to boost your system configurations as well as setting up networking between systemsadministration efficiency.

<u>Requirements for Success:</u>

:* '''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!'''

= Tips and Suggestions = Wiki Participation ==

* Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI edit these pages! Please feel free to fix typos or with the <code>poweroff</code>, <code>reboot</code>, <code>init</code>, or <code>shutdown</code> commands. Shut down your virtual machines before shutting down your main system.* If you get a message about the gnome-power-manager configuration at the login screen, you may have run out of disk space. Switch to a character-mode virtual terminal (for example, switch to VT2 by pressing Ctrl-Alt-F2). Login and take a look at the available space (with the command: <code>df -h</code>). If the <code>/</code> filesystem is full, delete some files (such as unused VM images in <code>/var/lib/libvirt/images</code>) and then reboot the system.* Fedora 13 Slowdowns: If your system is becoming very slow from time to time, it is probably due add links to a known issue with the Intel video driver, kernel, NICs, storage system, and hardware detection software (!)additional resources.
