1. Chapter Nine NetWare-Based Networking

2. Introduction to NetWare In 1983, Novell introduced its NetWare network operating system Versions 3.1 and 3.1—collectively known as NetWare 3.x—were introduced in the early 1990s Versions 4.0, 4.1, and 4.11—collectively known as NetWare 4.x— were introduced in the mid-1990s NetWare 4.11 is sometimes referred to as IntraNetWare NetWare 4.11 is sometimes referred to as IntraNetWare In 1998, Novell released version 5.0, and since has released versions 5.1 and 5.11—collectively known as NetWare 5.x Today – NetWare 6.5

6. Determining the Optimal Hardware for a Server When considering NetWare, note the number of NetWare loadable modules (NLMs) used by each service NLMs are routines that enable the server to run a range of programs and offer a variety of services NLMs are routines that enable the server to run a range of programs and offer a variety of services Each NLM consumes some of the server’s memory and processor resources (at least temporarily) Each NLM consumes some of the server’s memory and processor resources (at least temporarily)

7. A Closer Look at the NetWare Operating System Multiprocessing In versions 4.x and higher, NetWare supports the use of as many as 32 processors on one server In versions 4.x and higher, NetWare supports the use of as many as 32 processors on one server Takes advantage of symmetric multiprocessing Takes advantage of symmetric multiprocessing To use NetWare 5.x’s multiprocessing capabilities, simply install multiple processors in the server To use NetWare 5.x’s multiprocessing capabilities, simply install multiple processors in the server

8. NetWare’s Memory Model Whereas NetWare 4.x can use only physical memory, NetWare 5.x can work with both virtual memory and physical memory Protected mode Protected mode A manner in which NetWare runs services in a separate memory area from the operating system Caching Caching Process of saving frequently-used data to an area of the physical memory where it will be readily available for future purposes

9. The Kernel and Console Operations Kernel Core of the operating system Core of the operating system Server console Network administrator’s primary interface to a NetWare server Network administrator’s primary interface to a NetWare server 4.x not entirely graphical 4.x not entirely graphical 5.x text or graphics-based system 5.x text or graphics-based systemMonitor NLM that enables the system administrator to view server parameters such as protocols, bindings, system resources, and loaded modules NLM that enables the system administrator to view server parameters such as protocols, bindings, system resources, and loaded modules

11. The NetWare File System NetWare does not allow you to specify the file system types in the same way that Windows 2000 does It does offer its own high-performance file system that supports DOS, Macintosh, UNIX, OS/2, and Windows It does offer its own high-performance file system that supports DOS, Macintosh, UNIX, OS/2, and Windows

12. Compression NetWare 4.x and 5.x both support file compression In both NetWare 4.x and 5.x, unless the network administrator specifically chooses to prevent compression, compression on the server is enabled automatically Compression does increase file access time slightly; for this reason it is not recommended for extremely large files

14. NetWare Directory Services (NDS) Provides a system for managing multiple servers and their resources NDS tree NDS tree The logical representation of resources in a NetWare enterprise Figure 9-3: Simple NDS tree

17. Planning for Installation Where does the server fit in the NDS tree? What name will the server have? How many and what kinds of network adapter cards will the server use? What protocols and network services should the server use? What kind of disk controllers does the server have?

18. Planning for Installation How many, how large, and what kind of volumes will the server require? What additional services will the server support? In a simple installation, the most popular installation options are already chosen In a simple installation, the most popular installation options are already chosen In custom installation, it’s possible to determine which services and programs are installed In custom installation, it’s possible to determine which services and programs are installed What kind of license do I have? How can I remember all of this information?

19. The Installation Process NetWare can be installed from: CD (most popular method) CD (most popular method) Floppy disks (not recommended) Floppy disks (not recommended) Another server on the network Another server on the network This process is called an “over-the-wire” installation

20. The Installation Process After performing a NetWare 5.x installation and restarting the machine, your server should be functional After installing a NetWare server, verify that you can log on to that server as administrator from a Windows 2000 or Windows 9x workstation using the Novell Client for NetWare

21. Using the NetWare Administrator Utility (NWAdmin) To make you server functional, you will need to add users and other objects to the NDS tree After adding objects, you may want to modify their properties or even delete them An important tool in NetWare server management is the NetWare Administrator utility (NWAdmin)

25. Using the NetWare Administrator Utility (NWAdmin) You will find that your most frequent use of NWAdmin consist of: Viewing objects Viewing objects Modifying objects Modifying objects Creating objects Creating objects In short, NWAdmin is your link to managing your NDS tree
