What Did Linux Contribute

to the Movie “Titanic”?

• Simulation and Rendering Processing
• 3.5 times faster than SGI systems
• Running 24 hours a day, never stopped for 3 months to finish the special effects in the film.
• Linux’s commercial potential catches attention!

UNIX

• First developed in 1969 by Ken Thompson and Dennis Ritchie at Bell Labs.
• 1977 SCO Unix
• 1983 Sun OS
• 1986 IBM AIX
• 1991 Linux

Linux’s Strengths

• Multi-platform
  • Intel
  • Sparc
  • Alpha
  • Mac/Power PC
• Multi-user
• Multi-tasking
• Built on Open Standards
• Reliable

Linux’s Strengths (cont.)

• Lowers cost of both desktop and server compared to traditional Unix and Microsoft OS. - Low resource requirements - Intel 386 compatible or better - 2MB Ram - 10MB hard disk space - No licensing headache
• Compare for yourself

Distributions of Linux

• There are various distributors of Linux.
• A few major Distributors are:
  • Caldera Linux www.calderasystems.com
  • Corel Linux  www.linux.corel.com
  • Mandrake Linux www.linux-mandrake.com
  • RedHat Linux www.redhat.com
  • SuSE Linux  www.suse.com
  • TurboLinux  www.turbolinux.com

Caldera Linux

• Caldera OpenLinux is a multi-tasking, multi- user operating system that gives you the
• power and reliability of UNIX.
• OpenLinux is Caldera's "distribution"
• OpenLinux is ideal for small, medium, and large companies needs to optimize how much they want to spent on existing systems, hardware, & training

Mandrake Linux

• An enhanced version of RedHat Linux
• It has a powerful Graphical Desktop
• Comes with Apache Web Server, Netscape Communicator, and various other software

RedHat Linux

• Made for ease of use and installation.
• Configures TCP/IP for you.
• The new packaging system is made to allow upgrading to new Red Hat releases without reinstalling your system.
• No partitioning or backing up all your files needed for upgrading.

TurboLinux

• Very popular in Asia
• Geared towards corporate needs as well as the home desktop.
• Available in English, Japanese, and Chinese
• Contains powerful desktop applications such as StarOffice and Netscape.

• Created in 1991 by Andrew Tridgell of Australian National University by reverse engineering the SMB protocol.
• Is an open source software suite available for use to anyone under the GNU General Public License.
• Facilitates UNIX file system and printer sharing with Windows and LAN Manager clients

• Samba enables interoperability between Linux/Unix and Windows.
• Samba runs on:
  • Linux
  • Solaris
  • IRIX
    • The main o/s for Silicon Graphics workstations and servers. It incorporates Unix System V functionality.
  • HPUX
  • Almost all other versions of Unix
• Accessing files from Linux/Unix looks exactly like you are accessing an NT server.

Samba and Windows

• Windows NT OS uses a layered architecture with partitioned user and kernel modes similar to those of UNIX.
• NETBIOS – over – TCP/IP (NetBT) is used by Samba to share UNIX resources with Windows clients
• SMB AND CIFS are NetBT based protocols. Samba is an implementation of CIFS version 1.
• Windows 2000 uses Kerberos 5.0 for network authentication.
