<u>This course is the second in a series of courses about Linux technologies.* ULI101 taught you to be Linux ''user''.* In OPS235, you will move from being a Linux ''user'' to being a Linux system ''administrator''.* Later courses (OPS335 and OPS435) teach you to administer Linux servers and to use scripting to boost your system administration efficiency.</u>

As a system administrator, :* ULI101 taught you will to 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 powerLinux ''user''. You will be able to change anything on the systemIn OPS235, and you will also have the ability move from being Linux a ''user'' to damage or destroy the being a Linux system''administrator''.

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 == Learning by your time and ambition. You are encouraged to experiment and question liberally.Doing ==

Needed by the second class: # '''Fedora 13 Live CD''' (x86_64). You can burn this from ISO image on a CD or a DVD using the Freedom Toaster (in the Open Lab) -- however, this machine has problems with some types of DVDs. * The image is also available from:#* http://belmont.senecac.on.ca/fedora/releases/13/Live/x86_64/Fedora-13-x86_64-Live.iso - Seneca's mirror of the Fedora project. This is very fast, but is only accessible from within Seneca's network (notes that you can't access this from home). You can burn this disc on make during the machines in the Open Lab.#* http://get.fedoraproject.org - Accessible from any Internet connection.# '''SATA Hard disk in removable drive tray''' (at least 160GB). Please buy the tray from ACS or the bookstore as not all trays labs and assignments are compatible.# '''USB flash drive''' (64MB or more - 2GB or larger recommended. Warning: anything on this flash drive will be erased!)# '''[http://zenit.senecac.on.ca/~chris.tyler/ops235/2011-1/ops235_2011-1_lab_log_book.pdf Lab log book (PDF)]'''.

Needed for week 2: * 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!

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.* 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 to a known issue with the Intel video driver, kernel, NICs, storage system, and hardware detection software (!). See [https://bugzilla.redhat.com/show_bug.cgi?id=523646 Bug 523646] on the Fedora Bugzilla system. A fix for this problem is apparently in the works -- update your system regularly so that you get the fix as soon as it is available.** '''Workaround:''' Type this command as root (be patient, it will take a minute or two for the system to return to normal speed): <code>killall hald devkit-disks-daemon</code> = This is a Wiki! = You can edit these pages!
