* Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI 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.== Wiki Participation ==* 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 SlowdownsNote: If your system is becoming very slow from time You can edit these pages!

== What This Course is About ==
This course teaches the maintenance and administration of a UNIX server using Linux. Students will learn to install configure, customize, test and maintain common services available on Linux servers.
This course is the third in a series of courses about Linux technologies.
* ULI101 taught you to be a Linux user.
* OPS235 taught you to move from being a Linux user to being a Linux system administrator.
* '''OPS335 will teach you to ''administer'' Linux ''servers'' (web servers, DNS servers, FTP serversfirewalls, file sharing servers).'''
As a system administrator, you will be responsible for installing, configuring, adjusting, maintaining, and troubleshooting the operation of computer systemsLinux network services. You will potentially have several hundreds (or thousands) of people depending on the machines that you manage. 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 pack with the lab computers to set up a Linux system. You will also set up four several additional Linux systems using "Virtual Machines"virtual machines, and therefore gain experience with different types of system configurations as well as setting up networking between systems.
== Learning by Doing ==
Most of the learning in this course occurs through the hands-on problem solving that takes place in the ten labs and two assignments. Therefore, it's 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.
