COSC operating system LINUX INSTRUCTOR: Professor Mort Anvari Student Name: Fan Chang Student ID: Date:06/10/2000

Introduction n n LINUX is a free, from scratch operating system based heavily on the POSIX and UNIX APIs. n n LINUX itself is not UNIX, although many people call it that and you would be very hard pushed to tell the difference. n n This is because the UNIX trademark has a cost and is specific to systems that meet a complex set of X/Open standards. n n Kind of OS: open source UNIX

n n UNIX is a trademark that was transferred by NOVELL UNIXWARE. n n Microsoft's Windows NT Server Vs. UNIX — is, strangely enough, being upstaged by a Johnny- come-lately called LINUX. n n UNIX-clone LINUX’S emerging popularity gives small businesses another attractive alternative when plotting their network operating system (NOS) strategies, it also adds confusion to an already muddled issue

HARDWARE SUPPORT

Kernel: LINUX n The LINUX kernel was originally written by LINUS Torvalds(hence the name “LINUX” n The LUINUX kernel maintained by a team of developers. n The kernel itself is released under the GPL(GNU Public License).

RED HAT n n Red Hat routinely tests systems and peripherals to determine whether they operate correctly with Red Hat LINUX. n n The Red Hat Service Organization keeps these Hardware Compatibility lists up to date for all supported versions of Red Hat LINUX, which include i386, SPARC, and Alpha architectures 6.2,6.1,6.0,5.2.

Red Hat n n Red Hat believes that the hardware on these lists operates correctly with Red Hat Linux n n but because there are an infinite variety of computer system configurations and the manufacturing specifications and components of hardware change, Red Hat cannot guarantee compatibility with any hardware

RED HATE READY n n The Red Hat Ready Program is a useful tool for Independent Hardware Vendors. n n A vendor may submit its hardware (including peripherals and systems) to undergo a rigorous certification process performed by highly qualified in-house Red Hat Technicians. n n Certification earns the vendor the right to display the Red Hat Ready logo.

RED HAT READY n n The advantages of having your hardware certified under the Red Hat Ready Program are: n n Verification that your hardware is fully compatible with the current version of Red Hat LINUX. n n Use of the Red Hat Ready logo on approved products. n n Your customers will recognize the Red Hat Ready logo and know that your hardware can be trusted to perform when they run Red Hat LINUX.

LINUX---X WINDOW

Red hat linux 6.1 n Red hat linux6.1 features: n includes a new graphical installation process in addition to the more traditional character-cell installation mode. n Some new features are tools or applications that you can use, others are new versions of the kernel or desktop environments.

System Configuration With Linuxconf n Linuxconf is a utility that allows you to configure and control various aspects of your system, and is capable of handling a wide range of programs and tasks. n More information on Linuxconf, including its status, most recent release, and more can be found at the Linuxconf Project homepage: n /

Three menu interface linuxconf comes complete with a tree menu interface n 3-1 Linuxconf Entry Screen

3-2 filter control screen

3-3 users accounts screen

conclusion n thanks a lot for your concentration.
