4. NetWare 6 Features • There are a broad range of features. • Many features are not available in other NOSs. Lesson 7—Networking BASICS

5. Storage Management • Server storage is divided into logical volumes. • A volume may be one or more hard drives, CD-ROMs, DVDs, or SANs. • A storage volume can contain eight terabytes. Lesson 7—Networking BASICS

6. Storage Management Lesson 7—Networking BASICS

7. Storage Management • NetWare supports storage virtualization. • Storage pools can be from 1 to 254 volumes. • Storage pools can exceed the physical storage currently available. Lesson 7—Networking BASICS

8. Deployment • No additional client software is required to connect to a NetWare server. • NetWare automatically recognizes and supports protocols from different client operating systems. • NetWare 6 can be installed incrementally to existing networks. Lesson 7—Networking BASICS

9. iPrint • Any LAN printer can be accessible through the Internet. • iPrint can create a facility floor plan that shows the physical location of printers. • Users click on the printer icon to select the printer to use. • Printer drivers are automatically downloaded and installed. Lesson 7—Networking BASICS

10. iPrint Lesson 7—Networking BASICS

11. iFolder • Provides remote users a simple means of accessing files on a NetWare server. • Files and directories are accessed by special software or a Web browser. • Transmitted files are encrypted. • iFolder provides synchronization. Lesson 7—Networking BASICS

12. eDirectory • eDirectory is Novell NetWare’s directory service. • It can manage users running different NOSs. • It can create dynamic groups. • Persistent search can take action whenever change occurs. Lesson 7—Networking BASICS

13. User Accounts • Performed at ConsoleOne • Name • Surname • Password Lesson 7—Networking BASICS

14. Add Users to Groups • Performed at ConsoleOne • Group name (Organizational Unit) Lesson 7—Networking BASICS

15. Linux • Linux was introduced in 1994. • It was designed to be freely distributed across the Internet. • It is supported by a wide variety of users and companies. Lesson 7—Networking BASICS

16. Distribution • Linux is freeware. • Copies are freely available to download from the Internet. • The unique “flavors” of Linux are known as distributions. • Linux source code is also freely distributed. Lesson 7—Networking BASICS

17. Portability • Most standard NOSs only run on a limited number of hardware platforms. • Linux functions on a wide variety of hardware. • This includes Apple Macintosh, Intel, Sun, and IBM mainframes. Lesson 7—Networking BASICS

18. User Interface • The original version of Linux used a command line interface. • Users can choose a variety of different shells. • It also supports graphical user interfaces that are highly customizable. Lesson 7—Networking BASICS

19. User Interface Lesson 7—Networking BASICS

20. User Accounts • The client must be a Superuser. • Linux creates a default home directory. • Information is stored in /etc/passwd file. Lesson 7—Networking BASICS

21. Managing Files • The client must be a Superuser. • There are three types of users. • There are three file permissions. • Permissions are changed using chmod. Lesson 7—Networking BASICS

22. Summary • Novell NetWare 6 was once the most widely used network operating system for LANs. Although its popularity has dimin-ished in recent years, Net Ware still has a loyal following based on its reliability and advanced features. The current version of NetWare, version 6, was released in late 2001. Unlike Microsoft Windows NOSs, which are available in several different sizes, NetWare is available in only one single version. NetWare 6 is built around a concept that Novell calls One Net. Using the Internet, One Net is designed to provide instant access to net-work services through any device at any time from any location using standard protocols and open industry standards. Lesson 7—Networking BASICS

23. Summary (continued) • NetWare 6 provides several advanced features. NetWare allows storage pools to be created. Storage pools can be made up of 1 to 254 volumes. Each volume can be defined as any size, even if that size is beyond its current storage capacity. This enables a storage pool to be set up that exceeds the physical storage currently available on the network. Installation of NetWare is generally considered to be easier than several other NOSs. On the local client computer, no additional software is required to connect to a NetWare server because everything is done at the server level. NetWare also automatically recognizes and sup-ports the protocols that these different operating systems use for storing and sending files. Lesson 7—Networking BASICS

24. Summary (continued) • Two of the primary uses of a LAN are to permit users to access data files and to print using high-speed printers. Novell NetWare provides two enhanced features that make printing and data access very easy to use. NetWare has expanded the capabili-ties of network printing by a service known as iPrint. NetWare’s iPrint service can make any LAN printer accessible through the Internet. Another NetWare service known as iFolder gives remote users a simple means of accessing and synchronizing data files on a NetWare server. As with iPrint, iFolder also makes use of the Internet. Files and directories can be accessed remotely by using special iFolder software or a standard Web browser. Lesson 7—Networking BASICS

25. Summary (continued) • The network operating system that has attracted a large amount of attention in a relatively short period of time is Linux. Copies are freely available to download from the Internet. Linux also encourages users to modify the source code. This free access to Linux source code lets programmers from around the world add new features and tweak Linux to improve its performance and reliability. These new features are then incorporated into future versions of Linux or made available as patches to the current version. Linux, because it is “open,” is constantly being improved and updated at a rate faster than proprietary network operating systems. Linux functions on a wide variety of hardware platforms using different CPUs. Lesson 7—Networking BASICS

26. Summary (continued) • The original versions of Linux used a command line interface, which required the user to type commands using the keyboard. The command line interface sends the request to the shell, which interprets the commands. Linux offers a variety of differ-ent shells from which the user can choose to install. Linux also supports graphical user interfaces (GUI), which use a mouse to manipulate icons on a screen. The X Window System (or X) is the foundation of a Linux GUI. A feature of X is its ability to run different window manager programs. X allows users to select which window manager they want to use. Each of these window managers are totally customizable; users can change any part of the desktop, such as creating different borders, adding buttons and menu items, and deleting scroll bars.
