A Closer Look at the NetWare 6.5 Operating System:
NetWare Integrated Kernel
Core of NetWare 6.5 OS
Oversees all critical server processes
Started by server.exe, which runs from servers DOS partition
Takes advantage of SMP
Up to 32 processors
NetWare loadable modules (NLMs): Enable server to run variety of
programs and services Each consumes some of servers memory and processor resources

System for organizing and managing multiple servers and their
resources
Similar to Active Directory in Windows Server 2003
Treat every networked resource as separate object with distinct attributes
Objects belong to classes

Planning for Installation
Poor planning results in more work for installer, potential downtimefor users, and headaches for whomever supports server afterinstallation
Critical preinstallation decisions:
Where does the server fit in the eDirectory tree?
After servers context established, cannot change it
What name will the server have?
How many and what kinds of NICs will the server use?
What protocols and network services should the server use?

Planning for Installation (continued)
Critical preinstallation decisions (continued):
What will the Administrator password be?
What kind of disk controllers does the server have?
How many, how large, and what kind of volumes will the server require?
Initially all free space on hard disk assigned to default volume, SYS
What server pattern, or type, will the serverbe?
What kind of license do I have?
How can I remember all of this information?

Establishing Users and Groups
Need to add objectsincluding user objectsto eDirectory tree
Use ConsoleOne, Remote Manager, or iManager
To run ConsoleOne, computer must have ConsoleOne clientinstalled
Running same protocols as server
To run Remote Manager, point Webbrowser to IP address of server
management interface By default, port 8008 on server

Establishing Users and Groups (continued)
To start iManager, point browser to /nps/imanager.html page on
server
After eDirectory objects created, may want to change properties
Home directory: directory in which user can store files
By default, users have full access privileges to files and subdirectories
within their home directories

Traditional Client Access
Clients running Windows, Macintosh, and UNIX-type ofOSs
traditionally connected via a Novell client specifically designed for
that client
Client must have appropriate protocol suite installed
May require additional client software
Novell provides utilities to automatically install client software (and
updates) on all clients

Native File Access
NetWare capable of providing clients with direct access to NSS
using clients native file access protocols
Users can browse folders and directories as if connected to server
running same file access protocols
All file access protocols installed by default
Network administrator must set up network share for each protocol
Via iManager

Summary
With NetWare 6.x, Novell has maintained its NOSs traditional file-and print-sharing strengths while adding browser-basedmanagement tools; popular open source Web development tools; afast, efficient file system; and flexible methods for managing multipleservers, volumes, and storage objects
The NetWare Integrated Kernel is responsible for overseeing allcritical NetWare server processes
NLMs are routines that enable the server to run a range of programsand offer a variety of services

Summary (continued)
Using ConsoleOne, administrators can manage servers, volumes,disks, and eDirectory objects
iManager is the primary means of managing eDirectory objects inNetWare 6.5
NSS offers many advantages over traditional file systems, includingfaster access, more efficient use of memory, file compression,support of files or directories as large as 8 TB, support for sharing asingle application over multiple servers, capability to limit userdirectory and volume size, and browser-based management tools

Summary (continued)
eDirectory is NetWare 6.xs system for organizing and managingmultiple servers and their resources, including storage devices,users, volumes, groups, printers, and so on
The word schema refers to eDirectorys defined set of objectclasses and their properties
eDirectory follows a tree structure
Each object has a context that indicates where that object belongs inthe eDirectory tree
NetWare recognizes two naming conventions for a users context:typeful and typeless

Summary (continued)
User and Group objects can be created through ConsoleOne,
Remote Manager, or iManager
Clients can connect to a NetWare 6.5 server, browse directories,
and manage files in one of several different ways
NetWare 6.5 uses the DirXML tool to share data between eDirectory
and Active Directory or Windows NT domains
Nterprise Linux Services integrates NetWare and Linux clients and
servers
