Planning for Installation


Poor planning results in more work for installer,
potential downtime for users, and headaches for
whomever supports server after installation


Critical preinstallation decisions:


Where does the server fit in the eDirectory tree?


After server’s 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?

Network+ Guide to Networks, 4e

23

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 server be?


What kind of license do I have?


How can I remember all of this information?

Network+ Guide to Networks, 4e

Enable cryptography


Specify network protocols for each network adapter


If TCP/IP, specify server’s IP addressing information


Enter server’s host and domain name


New eDirectory tree or add server to existing tree?


Enter eDirectory information


Choose an Administrator ID and password


Select login method

Network+ Guide to Networks, 4e

26

Establishing Users and Groups


Need to add objects

including user objects

to
eDirectory tree


Use ConsoleOne, Remote Manager, or iManager


To run ConsoleOne, computer must have
ConsoleOne client installed


Running same protocols as server


To run Remote Manager, point Web browser to IP
address of server management interface


By default, port 8008 on server

Network+ Guide to Networks, 4e

27

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

server and its resources


Traditional client access


Native file access


Browser
-
based access

Network+ Guide to Networks, 4e

31

Traditional Client Access


Clients running Windows, Macintosh, and UNIX
-
type of OSs 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

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

Network+ Guide to Networks, 4e

34

Native File Access (continued)


Client must run same protocols and software
normally used to connect to a server natively
running its file access protocols


NetDrive: When installed on Windows clients,
allows access to directories on NetWare 6.5 server


Uses IPs such as HTTP and FTP

traditional file
-

and print
-
sharing strengths while
adding browser
-
based management tools; popular
open source Web development tools; a fast,
efficient file system; and flexible methods for
managing multiple servers, volumes, and storage
objects


The NetWare Integrated Kernel is responsible for
overseeing all critical NetWare server processes


NLMs are routines that enable the server to run a
range of programs and offer a variety of services

Network+ Guide to Networks, 4e

40

Summary (continued)


Using ConsoleOne, administrators can manage
servers, volumes, disks, and eDirectory objects


iManager is the primary means of managing
eDirectory objects in NetWare 6.5


NSS offers many advantages over traditional file
systems, including faster access, more efficient use
of memory, file compression, support of files or
directories as large as 8 TB, support for sharing a
single application over multiple servers, capability
to limit user directory and volume size, and
browser
-
based management tools

Network+ Guide to Networks, 4e

41

Summary (continued)


eDirectory is NetWare 6.x’s system for organizing
and managing multiple servers and their resources,
including storage devices, users, volumes, groups,
printers, and so on


The word “schema” refers to eDirectory’s defined
set of object classes and their properties


eDirectory follows a tree structure


Each object has a context that indicates where that
object belongs in the eDirectory tree


NetWare recognizes two naming conventions for a
user’s context: typeful and typeless

Network+ Guide to Networks, 4e

42

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
