Chap 1 ~ Introducing LINUX LINUX is a free-stable multi-user operating system that derives from UNIX operating system Benefits: 1) Linux is released under GNU (General Public License) – so its FREE! 2) Access to the source code is unrestricted (can be edited) 3) Multi-user, multi-tasking OS 4) Stable – can be updated on the fly! 5) Many applications such as OpenOffice can run on Linux 6) Security for System Administrator (open source software)

Choosing a LINUX distro Kernel – bunch of compiled code that provides the operating systems its core functionality Distros – bundle the kernel, system level programs, and free user-level programs in a variety of combinations Shell - Special program that allows user to interact by entering certain command from the keyboard Example; Redhat Fedora Novell Suse (KDE & GNOME) PCLinuxOS (KDE) Ubuntu (Gnome) KDE or K Desktop Environment (uses kwin window manager) and GNOME or GNU Network Object Model (metacity) are desktop environment with user friendly GUI that provides convience to the user

Evaluating Hardware suitability In preparing to install Linux Using the Windows XP utilities, run Scan Disk, Check Disk and Disk Defragmenter procedure Hardware ItemMinimum Requirement CPU Speed300Mhz min (1.0Ghz ++ is better) Memory size128Mb (256Mb ++ is better) HD drive capacity5Gb min (10Gb ++ is better)

Making space for Linux Installation 3 possible options; 1) Delete the Windows Partition – only 1 OS 2) Reduce the Windows Partition size – dual boot 3) Add second Hard disk drive – dual boot Benefits (option 3); 1)Windows space is not reduced 2)Lower risk of data loss 3)Maintain windows OS 4)Distinctly separated two OS 5)Any failure, one drive is affected

Chap 2 ~ Installing the OS Download the Novell SUSE ISO Image and burn the boot-CD image on a CD. Change your BIOS setting if it doesn’t boot directly from CD Start the installation process Select KDE as the desktop environment Set the partition and install updated packages Then, set the root/Administrator password

Root Settings root = superuser/Administrator Certain comands only can be executed by root for example ”reboot” sudo sudo command – allows command to be executed as if they were the superuser Change/define root password 1. pwd = print working directory 2. passwd = change password command 3. logname = reveals the logname 4. sudo passwd root = change the root password 5. su -l = switch user to root

Becoming the superuser When a user logs in the working directory is by default a user's home directory When the root /superuser logs in the working directory is the /root directory

Chap 3 ~ Evaluating Hardware Discovering the Control Center : Start -> Control Center

Making A Wireless Connection The KInternet application is bundled in Linux Suse to allow quick and easy connection to the net Double click the KInternet icon -> wireless connection Wireless connection should be configured to use security protocol such as WEP (Wired Equivalent Privacy) It requires an encrypted key before permitting access to the network The Control Center (YAST) also perform the same job as the control center
