Moving to Linux
Welcome to Linux
• Linux is a clone of UNIX. • It was created by Linus Torvalds in 1991
What is LinuxLinux is a kernel, the brains or control center of a collection of software packages, usually referred to as a Linux distribution.
The GNU GPL
• Linux is distributed under the GNU General Public License.
– in essence, the GPL says that anyone may copy, distribute, and even sell the program, so long as changes to the source are reintroduced back to the community and the terms of the license remain unaltered. Free means that you are free to take Linux, modify it, and create your own version. Free means that you are not at the mercy of a single vendor who forces you into a kind of corporate servitude by making sure that it is extremely costly to convert to another environment. If you are unhappy with your Linux vendor or the support you are getting, you can move to the next vendor without forfeiting your investment in Linux.
– In other words, "free as in speech", or simply "freedom".
What do you gain?
No operating system will ever be perfect, but Linux is getting pretty close. With Linux, you'll gain :
• Better Security• Increased Stability• Power from your OS• Money (saved!)• Freedom from legal hassles
What do you lose?
• Hardware and peripheral support– Some hardware is designed to run exclusively with
Windows (eg: Winmodems). Linux developers continue to work on drivers
• Shrink-wrapped software. – Hot new games or popular packages may not be
available at your local software store. Still, thousands of packages exist for Linux a click away.
• A step into the unknown. Learning curve.– Even moving from 95 to XP will take some retraining.
What about support?
• Corporate support through large vendors like Red Hat, SuSE, Mandrake,HCL, IBM, HP, and others.
• Worldwide community support : IRC chats, Linux User Groups, mailing lists
• Linux Documentation Project– http://www.tldp.org
• HOWTOs, man pages, books etc.• Linux technical support "among the
best"
Getting Linux• encourage you to use free and open
source software, improve it and pass it on.
• Is Linux really FREE?
– TANSTAAFL (Robert A. Heinlein)
– A free download will still cost you connection time on the Internet, disk space, time to burn the CDs, and so on.
– "Free as in speech"– "Free as in beer"– Distributed under the GPL

Getting Linux
Installations
• Modern Linux distributions are even easier to install than Windows.
• Most will repartition your drive automatically or resize it to allow for a Linux/Windows dual-boot system.
• Answer a few questions, click Next a few times and you are running Linux
Disk Partitioning Setup:
• Automatically partition.• Manually partition (with Disk Druid).
By selecting Automatically partitions, you will
not have to use partitioning tools to assign mount points, create partitions, or allocate space for your installation.
Installations
By selecting Manually partition what you haveto do:1.Create “BOOT” partition minimum of 100 MB.
2.Create “SWAP” partition of minimum DoubleSize of your physical RAM.
3.Create “USER” as per need.
4.Create “ROOT” partition as per your Hard disk space.
THAT’s ALL!!!!
Installations
Latest and easiest technique to install Linux:
Just download and install “Wubi” from http://wubi-installer.org/ in your Windows
And the rest thing will be done automatically.
“Wubi is an officially supported Ubuntu installer for Windows users that can bring you to the Linux world with a single click…..”
Installations
Knoppix CDROM
• "Moving to Linux: Kiss the Blue Screen of Death Goodbye!" comes with a customized version of Klaus Knopper's excellent Knoppix distribution.
• Run Linux from the CD without installing it.
But running from the CD is substantially slower than
running from an installed Linux.
“Feel free to copy and redistribute the CD”
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.
The command line• Common environment available in all distributions.• Works about 95% the same in all distributions.
CL Interface is not new !
Windows
The DOS Prompt
Linux
The BASH Shell
Desktop Options
• KDE (K Desktop Environment)– mature, friendly, integrated, and slick– east to use – first choice for new desktop users
• GNOME (GNU Network Object Model Environment)– also very nice with GNOME 2 releases
GNOME Desktop
A Linux graphical user interface
KDE Desktop
A Linux graphical user interface
• Today many business environments are commonly using Linux servers to provide their Networking Services.
• Network Services are all available And most are inbuilt
– Shared network locations for file sharing– Network Printing– Mail – Web– Proxy– DNS – DHCP– FTP – Firewall
NETWORKING
Desktop applications
• Linux also has many applications available and many of them are inbuilt applications.
• Word processing (OpenOffice, Koffice)• Programming (C, C++, Perl, Python, Java, PHP)• Graphics (GIMP)• Web browsers (Mozilla, Konquerer)• Email (Evolution, Mozilla, KMail)• Audio (amarok)• Games (MAME)
– See http://sourceforge.net for lots of opensource software
– All available as opensource applications.
Desktop Customization
• KDE is 3D customizable
– icons, fonts, colors, backgrounds, window decorations, themes, sounds, etc
– desktop can be themed to suit any personal tastes or
toadhere within a corporatelook and feel.
Working with Hardware
• When purchasing hardware in a store, always ask whether it runs with Linux -- even if you already know. It lets retailers know that there is indeed a Linux market out there.
• Use the "kinfocenter" command to check out your system's hardware.
• lspci and lsusb can be used at the command line to identify PCI and USB hardware.
Internet Access
Linux supports pretty much every form ofnetwork access:• Dial-up through Kppp or wvdial.• Cable modem connections through
dhcp.• ADSL • Modern distributions provide wizards
for getting you connected, like Mandrake's Drakconf tool or SuSE's YaST2.
Instant Messaging & Electronic Mail
• Linux Instant Messaging
clients support many
protocols and networks :
Gtalk, Yahoo!, MSN,
Jabber, ICQ, AOL,etc.
• Linux provides different
packages for E-mail like
Kmail, Evolution, Sylpheed,
Mozilla, and more
Updates by Distribution
• Red Hat Linux– up2date
• Mandrake– urpmi / Mandrake Update (or through
drakconf)• SuSE
– Online Update through YaST2• Debian
– apt-get
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
Image Manipulation
The GIMP is an amazingly powerful image manipulation package (similar to Adobe PhotoShop)
Multimedia
Modern Linux distributions offer an impressive selection of programs to satisfy your cravings for the multimedia experience. These include :
• Mixers• Audio players• CD players, rippers, and
burning tools• Video conferencing• Video and DVD players
Playing Music
• For CD's, look at KsCD.
• For MP3 and OGG files, XMMS and NoAtun.
• XMMS and NoAtun are slick, skinnable, and feature many visual and audio plugins.
Watching Movies
Many options including Dragon Player, Mplayer, xine, and Ogle.
• Watch video clips, DVDs, etc.• Mplayerpluginand Kmplayer letsyou integratemplayer into yourbrowser.
Playing Games
There are tons ofgames available forLinux. Several will
beinstalled as part of
yourKDE setup. And
againwith GNOME.
Windows Flavours
Linux ends the monopoly…
Linux Flavours
I hope you've enjoyed this little tour of Linux and the Linux Desktop. With all the power, stability,
security, fun, and flexibility at your command . . .
Linux: The future computing!
