  • Transcript

    • 1. Introduction To GNU/Linux GLOSS Vikas Mishra ( THE CYBERNAZI ) Viswanathan Karthik
    • 2. Welcome to Linux
      • Linux is a clone of UNIX.
      • It was created by Linus Torvalds in 1991
      • The PC existed but it was commonly running the Microsoft operating systems and used the Intel chip which did not support commonly unix.
            • DOS was available but didn’t meet his needs
            • Because Linus had used minix at Uni
            • Miniux was a small very basic UNIX-like system which was compatible with the Intel platform, being used in the universities for teaching.
            • And wanted same features at home but could not afford the cost of proprietary hardware on which to run a UNIX system.
            • So he started to create one based on the minux sourcecode – with many contributions from other people over the internet.
      • 1991 – Linus Torvalds created the linux kernel.
    • 3. What is unix
      • unix is an operating system
        • There are many different types of unix.
        • But they all came from a common background.
      • The Internet was built on UNIX.
        • TCP/IP is a native UNIX protocol.
        • Today 80% of the worlds Internet Web servers are using Linux.
      • unix has commonly been used for the past 30 years .
        • It was created in 1969 - long before Microsoft existed.
        • It was the 1st worldwide commercial operating system.
      • Unix has always commonly been used on mainframes.
      • Today as “linux” it is also commonly being used on PC’s as servers & desktops
    • 4. 1991 - Creation of Linux
      • Linus Torvalds did not write an entire operating system
      • He wrote a full complete version of a kernel.
        • Which he called Linux.
          • He chose a Penguin to represent his kernel
        • It’s main advantage is it’s - Compatibility for Intel systems.
      • This meant it could be run on any generic PC computer systems .
        • The Linux Kernel is written and distributed as an opensource product.
      • Linus Torvals is part of the opensource community
        • And as he believes in their opensource philosophy
        • The linux kernel was created with the input from many other developers around the world.
      • Opensource community believe in collaboration for the open development of products and distribution of all sourcecode .
      Linux Penguin
    • 5. Idea of the Opensource came from The Free Software Foundation
      • Richard Stallman started the …
      • Free Software Foundation
      • FSF is a non profit organization designed to protect and promote:
      • freedom for both the user and the IT industry.
        • The term free software, refers to S/W freedom, not price.
        • FREEDOM of Distribution NOT Free price
      • Basic Philosophy :
      • People who put their software under the GPL believe in ‘Free Distribution’
      • Meaning that they believe that the source code for the software cannot be withheld.
      • It does not mean that they or companies cannot charge for it.
    • 6. Open Source Software (FLOSS)
      • This type of software uses a GPL or opensource licences.
      • What it gives you?
        • Freedom to use
        • Freedom to examine
        • Freedom to redistribute
        • Freedom to modify
      • What it doesn’t let you do?
        • Deny these freedoms to anyone else
    • 7. GNU/Linux
      • 1990 Richard Stallman
      • One of the people who started this “open” philosophy.
      • Has nearly completed his new GNU operating system based on the UNIX system.
        • He had most of the modules but was still missing the main part !
        • The kernel.
      • 1991 Linus Torvalds creates the kernel then releases it out on an internet FTP server for everyone else’s opinion & help.
        • When complete Linux kernel was released under the GPL license.
        • Slowly but steadily news of Linux spread and work continued.
      • 1992 The Linux kernel is combined with the already created GNU modules & utilities and now becomes a fully useable operating system
        • Distributions of Linux start appearing.
      • There are now about 1000 Linux Users
      • Footnote: These figure are based on the OS Revolution movie
    • 8. The 1990’s
      • 1993 Internet explosion starts and there’s also an ISP explosion which
      • cause’s the 1st viable Linux commercial application.
        • The Apache Web Server .
      • There are now about 500,000 Linux Users
      • 1997 Eric Raymond writes a paper called the ‘ Catheral & Baazar ’ in which he
      • analyzes the development & differences of the
      • ‘ proprietary’ software model verse the ‘opensource’ software models.
        • The article takes the IT industry by storm.
        • Eric Raymond becomes a front man for the new opensource movement.
        • Netscape director reads the article and in direct response freely releases the source code of the Navigator software.
          • Netscape is the 1 st large company to go opensource.
      • There are now about 800,000 Linux Users
    • 9. Many Linux Distributions Appear
    • 10. There are many Linux Distributions
    • 11. Lates 1990’s
      • 1998
        • Linus, Linux & the opensource movement starts becoming commonly known. And gaining momentum.

          • RHEL - their enterprise/business version with which you purchase support
          • Fedora – their home version with no support
      • 2003
        • Novell buys SuSE Linux for $210 million
        • IBM is now the most powerful backer of Linux.
          • To counterbalance the world of Linux they make a 50 million dollar investment in Novell.
          • SuSE becomes the major enterprize competitor to Red Hat.
          • SLES - their enterprise/business version with which you purchase support
          • opensuse – their home version with no support
    • 13. Using Linux
      • Original Linux Kernel uses Command Line Interface
      • CLI ( Command Line Interface )
        • Universal Interface ( Administrative tool )
        • Hard to learn
      • GUI ( Graphical User Interface )
        • Looks different on each version of linux
        • All are great customizable desktop’s with good looking desktop
        • Easy to adopt and control by users
        • Easy controls and applicable tools
        • Easy use of Multimedia contents
        • Great opensource GUI applications available
    • 14. The command line
      • Common environment available in all distributions.
      • Works about 95% the same in all distributions.
    • 15. CL Interface is not new ! Windows The DOS Prompt Linux The BASH Shell
    • 16. Linux GUI Environments
      • Most distributions ship with a GUI
      • But they can be very different from each other.
      • There are competing GUI environments in Linux:
        • GNU Object Model Environment (GNOME)
        • Kommon Desktop Environment (KDE)
      • But the Core component of a linux GUI is called X Windows
        • XWindows is the just the engine on which a desktop manager runs and supplies the GUI desktop.
      • The GUI environment is created by X Windows in combination with a window manager and desktop environment
    • 17. August 18, 2009 suse
    • 18. GNOME Desktop A Linux graphical user interface
    • 19. KDE Desktop
    • 20. KDE Desktop
    • 21. GNOME Web Site Http://www.gnome.org
    • 22. Today many b usiness environments are commonly using Linux servers to provide their Networking Services
      • Network Services are all available
      • And most are inbuilt
        • Roaming user profiles
        • Shared network locations for file sharing

      • Email (Evolution, Mozilla, KMail)
      • Audio (amarok)
      • Games (MAME)
        • See http://sourceforge.net for lots of opensource software
        • All available as opensource applications.
    • 24. Openoffice
      • Many companies are now using linux on their desktops as their Office productivity suite:
      • Openoffice supplies the following inbuilt applications
          • Writer = word processing
          • Calc = spreadsheets
          • Impress = slide show’s
          • Base = database
