= Welcome to OPS235! - ''Introduction to Open System Servers'' ={| width="100%" align="right" cellpadding="10"|- valign="top"| width="55%"|== What This Course is About == <u>This course is the second in a series of courses about Linux technologies</u>
:* ULI101 taught you to be a Linux ''user''. In this courseOPS235, you will move from being Linux a Linux ''user'' to being a Linux system ''administrator''.
== Tips ==:* 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.
Tips and suggestions:* Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI or In this course you use an external SSD drive (USB 3) with the <code>poweroff</code>, <code>reboot</code>, <code>init</code>, or <code>shutdown</code> commands.* If you get lab computers to set up a message about the gnome-power-manager configuration at the login screen, you may have run out of disk spaceLinux system. Take a look You will also set up at the available space (with <code>df -h</code>). If the <code>/</code> filesystem is fullleast four additional Linux systems using "Virtual Machines", delete some files (such as unused VM images in <code>/var/lib/libvirt/images</code>) and then reboot the system.* If your system is becoming very slow periodically, it is probably due to a known issue therefore gain experience with the Intel video driver, kernel, and NICs. See [https://bugzilla.redhat.com/show_bug.cgi?id=523646 Bug 523646] on the Fedora Bugzilla different types of system. Apparently kernels 2.6.32.7-37 and higher (currently in testing) fix this issue -- so use 'yum update' regularly and watch for a new kernel update shortlyconfigurations as well as setting up networking between systems.
== Weekly Schedule ==:* 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.
Weekly topic, lab, and assignment information is available on the [[Winter 2010 OPS235 Weekly Schedule]] page.== Learning by Doing ==
== Supplies Checklist ==Needed immediately: # Fedora 12 Live CD. You can burn this from ISO image on a CD/DVD using Most of the Freedom Toaster (learning in the Open Lab or in the hallway near T1208).
