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

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

12
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

15
eDirectory (continued)

16
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

17
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

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 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?

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?

24
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

25
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

26
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

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

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

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

32
Traditional Client Access (continued)

33
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

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

35
Native File Access (continued)

36
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

37
Internetworking with Other Operating Systems
  • Novell has adopted LDAP directory standards
  • DirXML Novells tool for integrating eDirectory
    and Windows Active Directory or Windows NT
    domain data
  • Can synchronize Windows and Novell servers
    directories
  • Can configure so that Active Directory or
    eDirectory is authoritative source for directory
    information

38
Internetworking with Other Operating Systems
(continued)
  • Nterprise Linux Services Simplifies NetWare
    access for users running Linux NOS
  • Client tools for accessing eDirectory
  • Development tools for integrating Linux servers
    with DirXML
  • Browser-based file and print services
  • Novell purchased two companies that write and
    distribute Linux software
  • NetWare 7.0 will combine NetWare and Linux
    kernels
  • Full compatibility

39
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

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

41
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

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
