What is Novell NetWare?
• NetWare was developed by Novell to connect, manage, and
maintain network and its services.
• A NetWare network uses the NetWare software to enable
devices to communicate and allow resources to be shared.
• NetWare is a suite of software components run only on the
NetWare
server.
Some
components
run
only
on
workstations.
• Most administrative tasks are performed from workstations.

History of NetWare
1983:
1985:
1987:
1991:
1993:
NetWare X and NetWare S
NetWare 2.0
NetWare 2.11
NetWare 3.11 (Final Bindery-based operating system)
NetWare 4.0. Introduction of the LDAP-based Novell
Directory Services. Allowed management of an
organization’s network across WAN links. Novell had 85%
of the LAN market.
1998: Netware 5.0. Market share had declined steadily since the
release of Windows NT 4 in 1995. NetWare shifted from
IPX/SPX to TCP/IP as primary LAN protocol.
2004: NetWare 6.5
After 2004: integration with Linux.

The Resources
• A network resource is something you use, such as
a network printer or a volume on a disk drive.
• A network service is the system or method for
providing a resource.
• Most network resources and services provided by
NetWare servers can be used simultaneously by
multiple clients.
5
The Services
• Novell Directory Services (NDS): After network
communications Novell Directory Services is the most
fundamental network service NetWare provides.
 NDS provides the following functions:
1)
2)
3)
4)
5)
Maintain a database of information on resources
Process client requests for network resources.
Locate the resource on the network
Verifies the client.
Connects the client with the resource.
6
NDS/eDirectory
• Novell Directory Services is now known as eDirectory.
• Users authenticate to the network. Once authenticated, user can be
granted rights to access any resource on the network.
• A directory tree is a graphical representation in eDirectory of the
organization of network resources.
• Generally, resources are grouped by location.
• Security can be applied to each grouping
separately.
• Database can be partitioned for multiple
locations.
• eDirectory can run on Windows, Linux, and Solaris.
7
The Services (Cont.)
• Security: The network services in NetWare have
their own types of NetWare security.
• Each service provides methods for you to regulate
access to network resources.
• The primary component of network security is
your account which identifies:
– who you are and
– what you are allowed to do on this network.
8
NetWare Server
Communications
• Protocols (IP and IPX)
• NetWare has traditional used IPX and its protocols
for network communication.
• NetWare 5 allows a choice of running networks
with IPX, with both IP and IPX, or with pure IP
• IP comprises a set of publicly available protocols
that provides the means by which computers
communicate on the Internet.
• IPX comprises a set of protocols that facilitate
communications between computers on NW

networks
Manage Network Access
for Users
• NetWare Administrator: NetWare Administrator
is Windows-based utility that lets you easily create
and modify objects in the NDS tree.
• ConsoleOne: is a Java-based utility that enables
you to create user objects through a browser.
• UIMPORT: is DOS based and enables you to
import users from a database application to NDS.
10
Manage Network Access for
Users (Cont.)
Z.E.N.works (Zero Effort Networks): it includes Novell Application
Launcher (NAL) and Workstation Manager to facilitate centralizing
software distribution and desktop management. It also do the
following:
1.Distribute and maintain application on workstation
2.Launch applications automatically for users
3.Import object information into NDS eDirectory
4. Centralize the location and administration of user profile
5.View & update client configuration.
11
Novell Distributed Print Services
(NDPS)
• NetWare allows all workstations to use the same
printers.
• These networked printers can be attached to NetWare
servers, workstations, or the network cable.
• NDPS simplifies network print services administration
by providing automatic printer discovery and
configuration of printing resources.
12
Novell Storage Services (NSS)
• NSS supports systems with large files and volumes
• NSS allows up to 8 TB file size, and holds up to 8
trillion files in an NSS volume.
• With NSS, hard disk space can be fully utilized.
• NSS and the traditional NetWare file system run
side-by-side.
13
What NetWare 5 Delivers
To Network Server In General
The most advanced directory-based management
system on the network using the following:
– Z.E.N.works
– Novell Directory Service (NDS)
– ConsoleOne
– Novell Distributed Print Services (NDPS)
14
What NetWare 5 Delivers
To Network Server In General
• Strategic
platform
delivering
scalable
network services using :
– Open standards-Pure IP
– Dynamic Host Configuration Protocol (DHCP)
– Domain Name Services (DNS)
15
What NetWare 5 Delivers To Network
Server In General
• Scalable application support
– Java server Software Development Kit (SDK)
– Multi-Processing Kernel (MPK)
– Oracle 8
• High level reliability, scalability, performance, and
security:
– Novell Storage Services (NSS), NDS
16
NetWare Client
• NetWare client software runs on the operating system.
• Allow the computer to access the Novell network as
though it were a physical extension of the computer itself.
17
NetWare Client
• The client automatically locates network services,
having them appear transparently to the user of
the operating system.
• Client software can be configured to use a
particular server for authentication and particular
service locations.
18
BorderManager
• Protects LAN from intrusion from unauthorized external hosts.
• Allows administrator to monitor users Internet usage.
• Border Manager includes:
1.
Network Address Translation Server. Allows clients on LAN to share single
public IP address.
2.
Proxy Server. Reduces web traffic costs by caching regularly
accessed sites.
3.
Virtual Private Networking. Allows remote clients to connect to LAN over
encrypted tunnel.
4.
Content Filtering Server. Allows content to be filtered, restricting LAN users
from accessing dangerous of forbidden information.
19
GroupWise
• GroupWise is collaboration software that
allows users to:
1.
2.
3.
4.
5.
Send and receive e-mail
Schedule meetings
Define tasks
Manage To Do lists
Store/retrieve documents.
• GroupWise is a competitor of Microsoft
Exchange
Server
and
has
similar
functionality.
20
ZenWorks
• ZenWorks gives the administrator the ability to control the
look and feel of desktop computers through the use of
policies.
• Policies are sets of rules that can be applied to user
accounts, group accounts, or computers.
• ZenWorks can provide:
1. Remote control services, similar to Remote Desktop
on Windows.
2. Deploy applications over the network and hard disks.
3. Perform hardware and or software inventory of all
computers on the LAN.
21
Remote Administration Tools
• iManager is a Web-based administration tool that
can perform day-to-day tasks such as:
• Adding users
• Changing passwords
• Managing DHCP and DNS servers.
• To perform a task using iManager, a user must be a
member of a pre-defined administrative group that is
responsible for performing that task.
• iManager can be used on any standards compatible
Web browser.
22
Remote Administration Tools
•ConsoleOne
• Java-based utility.
• Because it is written in Java, it can run on any of
the platforms that support NetWare.
• Snap-ins can be used to manage ZenWorks or
GroupWise using ConsoleOne.
• ConsoleOne can not be used to administer
printers, DHCP, and DNS servers.
23
Sharing Files and Printers
• A benefit of NetWare is that it provides a simple and
consistent
interface for file sharing across multiple
operating systems, such as Linux, Macintosh, and
Windows.
• NetWare handles all of the messy differences in the way
permissions are allocated, so that files and folders can be
easily shared across the LAN.
24
Sharing Files and Printers
•There are two types of shared printers in NetWare 6.5:
• Controlled access printers
• iPrint.
1. Controlled access printers
• Objects within eDirectory.
• Access to these can be restricted on the basis of user and
group accounts.
2. iPrint
• uses Internet Printing Protocol (IPP) standard.
• This allows printing across any TCP/IP-based
network, including the Internet.
25
Summary
• Novell NetWare is a popular network operating system that once
held approximately 85% of the LAN market.
• Novell NetWare uses eDirectory, an LDAP-based directory service, to
store information about the network.
• Objects in eDirectory are usually sorted on the basis of location.
• BorderManager is an add-on to NetWare that can be used to provide
firewall, NAT, content filtering, and proxy services.
• ZenWorks is an add-on to NetWare that can be used to manage
network clients.
• iManager is a Web-based administration tool that can be used to
perform any NetWare administrative task.
• ConsoleOne is a Java-based administrative tool that can perform
26
most, but not all NetWare administrative tasks.
