Usage of FOSS and GNU/Linux installation session given for 4th n 2nd sem students of CS, GECH.

1. Usage of FOSS
and
GNU/Linux installation

2. FOSS
FOSS stands for Free and Open Source software.
Satisfy 4 degrees of freedom as stated by FSF-
• Freedom to run the program for any purpose
• Freedom to study how the program works, change it to
make it to do what you wish.
• Freedom to redistribute copies to help others.
• Freedom to distribute copies of your modified versions
to others.
http://www.gnu.org/philosophy/free-sw.html

3. Why use FOSS?
• The availability of the source code.
• The right of code modification,
improvement and redistribution.
• Large base of developers and users.
• Have an alternative.
• Free marketing and support.

4. Why FOSS is not yet popular?
• General lack of awareness about the Free
Software and its existence.
• Hardware vendors usually bundle
Windows with their systems and do not
offer choice to the customer!
• False thinking of less user friendliness in
FOSS.

5. Benefits of Using FOSS
• Reducing total cost of Ownership.
• Security
• Reliability/Stability
• Piracy, IPR

36. Installing Packages/Software
Two ways for RedHat based systems-
• RPM(RedHat Package Manager)
• YUM(Yellowdog Updater, Modified)

37. Using RPM
• Know about your kernel and architecture
type. (Use “uname – a” command)
• Download the required rpm file from
internet(rpm.pbone.net , rpmfind.net)
• Install using command-
$su – c “rpm –ivh filename.rpm”
• Press Enter and give your root password and
wait until the prompt returns.
• Sometimes this may result in dependency
problems if they’re not resolved.

38. Installing freeglut-devel using rpm

39. Using YUM
• More easier way to install any
software/package.
• No need to worry about type of kernel and
architecture.
• But you need internet connection during
installation.
• Command is-
# yum install pkgname

40. Installing freeglut-devel using YUM

41. Installing VLC player in Fedora
Use the following commands-
$ su –
# rpm –ivh
http://download1.rpmfusion.org/free/fedora/rp
mfusion-free-release-stable.noarch.rpm
# yum install vlc

42. Virtualization

43. Virtualization
You can use virtualization software to install an
Operating system inside an existing Operating
System!
Limitations: Some devices are not detected and
there must be minimum of 2Gb RAM.
Available virtualization software are-
• Virtual Box
• VMware Player

44. Virtual Box
Installing Virtual Box is as simple as installing any simple
software.
But while installing Operating system inside Virtual box, be
sure to save your virtual drive outside host machine drive.
You can install as many Operating systems as you wish
unless you run out of memory.!
Only .iso image of the OS is enough to install it and no need
of external cd/dvd while installing in virtual box.

45. Creating new virtual machine in VB:
Click on “New” in the main window.

46. Select your OS from top down menu and
give some name to the virtual machine.

47. Set the RAM size for your VM

48. Simply click “Next”

49. Again “Next”..

50. Once again “Next”..!!

51. Here you can set the VM size and
click on folder icon.

52. Store your VM outside Host machine drive.

53. Its done, click on Create to create your VM

54. Now start your VM from Virtual Box main
window to get this first run wizard.

55. Select installation media or browse to your
iso media file by clicking on folder icon.

56. After selecting installation media,
you can start your VM.
From here on, the normal installation of fedora begins.

57. When things go wrong.

58. File system check error
Give root password for maintenance (or type
Ctrl D to Reboot)

59. Enter root password to get the prompt
#
Now simply type “fsck” and press Enter
# fsck
Press y when it asks-
fix errors<y>?
Type “reboot” when the prompt returns
# reboot
Now fedora boots normally if the errors are fixed by
fsck.

60. Rescue the lost Fedora
• This works only if the partition of Fedora is
not formatted or deleted while installing
Windows.
• Need original type of fedora media to
rescue.
• Boot your media to get the following
screen and select “Rescue installed
system”.

61. Select “Rescue installed system”
and press Enter

62. Select continue and press Enter

63. • Start the Grub shell with the grub command:
# grub
• This will show the grub shell like this-
grub>
• Use the find command to locate the partition
containing the boot files by searching
for /boot/grub/grub.conf . Grub will report
the partition using its own syntax:
grub> find /grub/grub.conf
(hd0,0)

64. • Use the root command to configure the
partition from which the boot files are to be
loaded (use the partition ID from last step):
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
• Use the setup command with this drive ID to
install the Grub bootloader code:
grub> setup (hd0)
• Quit the Grub shell with quit:
grub> quit
#

65. • Type reboot to get back your Fedora-
# reboot
• Now fedora boots along side with
Windows like it was before.
