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 NetWare1983: NetWare X and NetWare S1985: NetWare 2.01987: NetWare 2.11 1991: NetWare 3.11 (Final Bindery-based operating system)1993: 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 6.5After 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) Maintain a database of information on resources

2) Process client requests for network resources.

3) Locate the resource on the network

4) Verifies the client.

5) 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 9

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 DeliversTo 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 DeliversTo 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. Send and receive e-mail2. Schedule meetings3. Define tasks4. Manage To Do lists5. 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 most, but not all NetWare administrative tasks.
