Caldera OpenLinux

Objectives

 Explain the basic knowledge of Linux  Introduce the features of Linux  Identify Linux performance  Focus specifically on Caldera OpenLinux installation

Why Linux is Important

 Most widely install Unix variant

 Linux ’s growth and popularity is due

to:

 Flexibility-the system is freely distributed and modified with source code available to anyone  Reliability- system maintains a very clean separation between user processes and kernel processes  Economy-the initial cost is low because of open source

The Power of Open Source

 Collaborative, networked development

is a new model of software

development made possible by the

internet

 Open source accelerates the

development process between

developers and users

 Allows Linux to be thoroughly

debugged because it is tested by

thousands of programmers world wide

The Essential Applications

 Office Applications  Ex: StarOffice, Koffice, Applixware and Corel Wordperfect  Email Clients  Ex: kmail, spruce, netscape and mozilla  Graphic Editors & Manipulators  Ex: The GNU Image Manipulation Program(GIMP)  Audio, Video and DVD  Video clips compact player-xanim  Mpeg player-gtv, mtv  DVD player-Livid  MP3 player-mpg

 Internet Browsers  Ex: Netscape  Internet Chat  Ex: Xchat  Card Games & Desktop Toys  PySol, minesweeper  Finance Managers  Ex: X-Accountant and Freeside  Web Page Editors  Ex: Amaya  Voice Recognition  Xvoice works on any X11 application  CvoiceControl is used on Linux console

Space Requirements &

Coexistence

 Space Requirement 200 to 500 megs  2megs, but 4 megs of RAM are recommended  Linux could either co-exist with other OS or could be a stand alone OS for installation and use

Linux Installation Overview

I. Collect configuration information on hardware before installing II. Know the vendor and model number for each card in machine III. Rearrange (repartition) disk to run a “dual-boot” system - Linux and Dos or Windows or both IV. For EIDE/ATAPI CDROM I. Check the BIOS settings for your machines capability to boot from CDROM

Linux vs. Windows NT

Common:  Proxy services are available for both platforms  Both server operating systems support Web, Network News Transfer Protocol and FTP services for giving end users access to the Internet  OpenLinux and NT Server support access via HTTP, FTP and Network File System links  For LAN access by Windows clients, both server operating systems support TCP/IP and IPX/SPX

Cont’………..

Linux

 Linux supports numerous TCP/IP applications, including terminal services  Windows clients can get to files sitting on a Linux box via Samba, setting up user access this way is somewhat more difficult than configuring file shares under NT Windows NT  documentation is a bit skimpy, and online help screens can be disjointed and aren't a substitute for training  sophisticated questions about NT problems often go unanswered

Linux vs. NT continued…

Linux  Caldera had a better mixture of supplied documentation  Linux support can be obtained by any of the commercial Linux vendors, such as Caldera, for an extra fee Windows NT  Microsoft's Web server-based Knowledge Base is a good source for fixes to common problems

Installation Methods

 Insert the "Kernel & Installation" CD-ROM into your CD-ROM drive and reboot your computer.  Boot from the Installation floppy diskette  Install directly under Windows
