1 Presented by: Heber Martinez - Background Fernando Navarro - KDE Jane Wong - Corel Linux Gary Yasuda - Init Levels Danny Corona - System Admin. Mark Cheng - Multimedia LINUX

2 LINUX (LIH- nuks )  Unix  Originally developed at AT&T as a multitasking system for minicomputers and mainframes in the 1970’s.  Linux  Developed primarily be Linus Torval.  Inspired by Minix.  Kernel uses no code from AT&T or any other proprietary source.  Developed by a group of volunteers, primarily in the Internet, who exchange code, report bugs and fix problems.

3 What is so special about Linux.  Linux is said to be:  Reliable.  Simple.  Free!  Runs on a variety of platforms.  considered the most important free software achievement.  Able to turn any or better PC into a workstation.

4 LINUX  Features:  Complete multitasking, multiuser OS.  Compatible with Unix standards.  Supports virtual consoles.  Supports various file systems for storing data.  Provides complete implementation of TCP/IP networking software.  Include device drivers for many Ethernet cards.

5 LINUX  Features (cont.)  Kernel  is developed to use protected-mode features of Intel and better processors.  supports demand-paged and loaded executables.  supports copy-on-write pages.  Linux can coexist with other OS on the same machine.

6 GNU/Linux K Desktop Environment  KDE is a powerful GUI desktop environment for Unix workstations.  Provides ease of use, contemporary functionality, and the technological superiority of the Linux OS.  KDE is an internet project that is "Open" in every sense.  All KDE sources are open to everyone and may be distributed by anyone subject to the well know GNU licenses.  KDE is a mature desktop suite.  Visit for further information.WWW.KDE.ORG

7 The GNU Project  Launched in 1984 to develop a completely Free Unix- like operating system: The GNU System. Many flavors of the GNU system are currently in use, i.e. Caldera, Redhat, Corel, etc.  These GNU Systems use the Linux Kernel, these systems are incorrectly called "Linux", they should be called GNU/Linux systems.  GNU is "Copylefted". Copyleft uses copyright law in reverse. It allows software to be used, modified, and distribute modified versions. Modified versions may not add restrictions of their own.  Visit for more information.www.gnu.org

8 Current KDE Distribution Includes the following packages:  KDE-Libs: Various Run-time libraries  KDE-Base: The base components  KDE Graphics: e.g. Kpaint, Kfax, Kghostview  KDE Utilities: Kedit, KCalc, Knotes  KDE-Multimedia: KMidi, Kmodplayer, Kmixer, KSCD  KDE-Games: Kasteroids, Kpat, Ktetris  KDE-Admin: Various rools to aid system administration

9 Current KDE Distribution Includes the following packages:  KDE-Network: Kppp, Krn, Kmail  Most current distributions of Linux Use a modified version of KDE. Corel calls its version Enhanced KDE.  Visit Linux.Corel.com, Linux.com, Linuxworld.com for more information.  Demonstration.

10 The Value of Linux Application  Linux is a complete multitasking, multi-user operating system. It supports various file system and applications.  Linux is much more compact and runs similar applications much faster than Windows.

11 Lower Cost  Most of Linux software and applications are inexpensive, which you can purchase in diskette or CD-ROM format. E.g. CorelDraw, WordPerfect 8, Domino R5, games, etc….  Linux is free and easily downloaded from the internet, or can be purchased at a much lower cost than Windows software.

12 Ease of Operation  Corel Linux has an Update wizard which can install more recent versions automatically.  Use Corel update to remove applications that you no longer want to use.  Reinstall deleted applications at any time.

13 Init Runlevels  0 -- Halt level  1 -- Single user mode  2 -- Multiuser mode (with no shared resources)  3 -- Full Multiuser mode  4 -- Not used  5 -- Full Multiuser mode (with X-based login screen)  6 -- Reboot

14 Init Program’s Main Roles  It creates processes, which has the effect of bringing the system up to the default run level.  It controls transitions between run states by re-reading the inittab file.

15 Inittab File Defines  The system’s default run level  What actions to be taken when the system enters a new run level  What processes to start, monitor, and restart if they die

16 Run Control Scripts  The scripts for starting and stopping system services are located in the rcR.d directories, where R is the run- level.  Files that start with S are used to start processes.  Files that start with K are used to kill processes.

17 Init.d Directory  The start and kill files in the rc#.d directories are hard linked to scripts in the init.d directory. This is done to facilitate booting.  An important advantage of having the actual run control files in the init.d directory is that you can start and stop individual processes from a single location without changing run levels.

18 Managing Corel Linux Systems  Corel Linux and the role of the System Administrator  System Administration Utilities  Hands on demonstration

19 Corel Linux and the role of the system administrator  System administrator’s role  Unlimited privileges  No restrictions to functions performed on OS  Caution must be used at system level

20 System Administration utilities  Root user  User manager  Event viewer  Control center

21 Hands-on presentation  user manager  task manager  process manager  mime editor  font manager  file manager  event viewer

23 LINUX Multimedia  Mark’s Linux Application List - Multimedia Well, Linux is a multitasking OS, so it's a perfect OS for multimedia. AuMixer Console-mixer tool. For: Does everything that you've expected! Against: Nothing Get it NOW at: Related:http://jpj.net/~trevor/aumix.html B-play Sound player, pretty good. For: Small Against: Nothing Get it NOW at: ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Related:ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Cthugha This is a Linux port of the Dos program CTHUGHA (well, funny name, indeed). It's an entertaining application that will grab sound (from for example a CD) and display visual effects on the screen. While playing the audio. Not so useful, but, cool :). For: Amazing Against: I want more and smoother colors in the effects Get it NOW at: Related: ftp://sunsite.unc.edu/pub/Linux/apps/sound/lightshow/http://www.afn.org/~cthugha/ftp://sunsite.unc.edu/pub/Linux/apps/sound/lightshow/

24  Cont. Funktracker Gold The only Tracker (MOD-maker) for Linux...until Maube (look under) will be released. But it's not as good as (for example) FastTracker II. I hope they will update it... For: The only alternative (yet) Against: Ugly, disabilities Get it NOW at: ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/ Related: MikMOD Regular MOD player, plays most of the MOD-file types - in the way YOU wish. You can also get a X- Interface (haven't tested). For: Good MOD player Against: Nothing to say Get it NOW at: Related:ftp://sunsite.unc.edu/pub/Linux/apps/sound/players/http://www.tohs.abacom.com/mikmod/ MiXViews Oh! A full futured sound recording / editing program. Does everything and more. You have many effects and so on. I only find some disabilities: bugs (a few), no "dyncamic" recording, not so many file formats, ugly GUI. For: Fast, great (!) Against: Ugly GUI (!)
