• NetWare 6.5s key features
• Support for multiple processors, multitasking,
  and SMP
• Flexible use of virtual and physical memory
• eDirectory
• Simple, centralized management of multiple
  clients, resources, and services

• Multiple, integrated Web development and delivery
  services
• Support for multiple modern protocols
• Excellent integration with other NOSs and support
  for many different clients
• Remote client services
• Built-in clustering services
• Provisions for monitoring server performance,
  automatic backups, and resource utilization

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

6
A Closer Look at the NetWare 6.5 Operating
System NetWare Integrated Kernel (continued)

• Load or unload NLMs through servers console
• Enables network administrator to manage disks and
  volumes and modify server parameters
• Monitor text-based menu system
• ConsoleOne graphical menu system
• X Server NetWare 6.5 servers graphical desktop
• Remote Manager access console commands via Web
  browser on another network computer

NetWare File System

• Novell Storage Services (NSS)
• 64-bit interface
• Files or directories up to 8 TB
• A trillion files in single directory
• File compression
• User and directory space restrictions
• Advanced fault-tolerance techniques
• Efficient use of memory
• Browser-based volume management
• Split volumes over multiple storage devices

10
NetWare File System (continued)

• NSS-based system may have up to four partitions
• One must be a DOS partition
• Primary boot partition
• Unlimited volumes on each partition
• Volumes are basis for organizing files and
  directories
• NSS can combine free storage space from multiple
  storage devices into a storage pool
• Provides flexibility
• iManager GUI tool used to manage objects

eDirectory

• NetWare 6.5s directory database
• 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
• eDirectory information stored in database that
  supports LDAP
• Compatible with other NOS and Internet directories

13
eDirectory (continued)

14
eDirectory (continued)

• Schema defined set of object classes and their
  properties
• Base schema simple schema installed by default
  with eDirectory
• Extended schema changes made to base schema
• Trees and OUs
• Hierarchical organization
• Tree can have one root
• Tree Object

15
eDirectory (continued)

• Trees and OUs (continued)
• Below root is an organization object
• Branches out in hierarchical arrangement of OUs
• A user is a leaf object
• Naming Conventions
• Each eDirectory tree object has a context
• Indicates where object belongs in the tree
• Consists of objects OU names, arranged from
  specific to general, plus organization name
• Typeful and typeless contexts

Installing and Configuring a NetWare 6.5 Server
The Installation Process

• Installed from CD or another server on network
• Installation tasks
• Select language
• Select regional settings
• Accept License Agreements
• Choose Default or Manual installation
• Prepare boot partition
• Choose pattern
• Select components to install (Manual
  installation)
• Copy files

21
The Installation Process (continued)

• Tasks to set up server
• Name server
• Enable cryptography
• Specify network protocols for each network
  adapter
• If TCP/IP, specify servers IP addressing
  information
• Enter servers 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

22
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
  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

Client Services

• Several ways for different types of clients to
  access server and its resources
• Traditional client access
• Native file access
• Browser-based access

26
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

27
Traditional Client Access (continued)

28
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

29
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

30
Native File Access (continued)

31
Browser-Based Access

• Users can navigate directories and manage files
  via Novells NetStorage tool
• Only need to have TCP/IP protocols installed and
  configured
• Uses standard Internet application protocols
• Users connect to URL on server
• By default, servers IP address (or host name)
  plus /NetStorage

32
Summary

• With NetWare 6.x, Novell has maintained its NOSs
  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

33
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

34
Summary (continued)

• eDirectory is NetWare 6.xs 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 eDirectorys 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
  users context typeful and typeless

35
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
