Lesson 14 – Novell NetWare 6.06
Novell’s Network Objects
NDS (Novell Directory Services) is a global database of network objects and users.
NDS uses a tree structure to organize all network objects.
There are three major objects contained in the NDS database:– Root objects– Container objects– Leaf objects
Lesson 14 – Novell NetWare 6.07
The Root Object
The root object is the beginning of the NDS tree.
All NDS objects exist in the root. Each NDS tree can have only one root.
Lesson 14 – Novell NetWare 6.08
The Container Object
Container objects organize the NDS tree. There are four main types of container objects:
– Organization objects– Organizational Unit objects– Country objects– Locality objects
Lesson 14 – Novell NetWare 6.09
The Leaf Object
Leaf objects hold information about network resources, such as servers and printers.
The system creates two leaf objects during installation:– The NetWare Server object– The Admin user object
Lesson 14 – Novell NetWare 6.010
Novell ConsoleOne
ConsoleOne is an administrative utility that provides a single point of administration for network resources.
ConsoleOne requires a 200 MHz or faster processor, 128MB of RAM, and 37MB of disk space.
Lesson 14 – Novell NetWare 6.011
Disk Management
The main components of the NetWare file system are– Volumes– Directories– Files
Lesson 14 – Novell NetWare 6.012
Volumes
Volumes are used to organize the network space that is allocated for storing programs and files for access by the network.
The system can use volumes to allocate disk space in three ways:– One volume per disk drive– Multiple volumes per disk drive– One volume spanning multiple disk drives (up to 32)
Lesson 14 – Novell NetWare 6.013
Data Storage
Data is stored in volumes in units called blocks. A block is the amount of data read to or written
from a volume at a time. Suballocation allows data from multiple files to
be stored on the same block.
Lesson 14 – Novell NetWare 6.014
Guidelines for Using Volumes
Up to 64 volumes are definable on one NetWare Server. The following rules apply to volumes:– Volume names must be from 2 to 15 characters
long.– Each volume on the server must have a
different name.– Spaces, commas, backslashes, and periods are
invalid characters in volume names.
Lesson 14 – Novell NetWare 6.015
Suggested Guidelines for Using Volumes
Always reserve the SYS volume for operating system files. Create one or more volumes for applications and data
files. If fault tolerance is vital, create only one volume per disk
drive. If disk performance is vital, span volumes over multiple
disk drives. If both performance and fault tolerance are important,
mirror the disk drives
Lesson 14 – Novell NetWare 6.016
Directories
Directories organize files and restrict the amount of space that certain users or applications can use on a volume.
The operating system stores required files and utilities in three directories on the SYS volume:– Login directory– Public directory– System directory
Lesson 14 – Novell NetWare 6.017
Guidelines for Creating Directories
As a network administrator, you are responsible for creating directories necessary for the company to meet its needs.
There are four directory types suggested by Novell:– Application directories– Shared directories– DOS directories– User Home directories
Lesson 14 – Novell NetWare 6.018
Files
Files are used to store data on the network. At the beginning of each volume, NetWare
stores the filename, location, owner, creation/access dates, and attributes in an area called the directory entry table (DET).
Lesson 14 – Novell NetWare 6.019
File and Folder Security
The type of file system used on the drive determines the level of security that can be set.
With NTFS, owners and administrators can set file and folder security.
Lesson 14 – Novell NetWare 6.020
Creating Users
Before creating user and group objects, the container object must be created that will hold these users and groups.
Properties can be assigned to each user to control their access to the network.
To make the creation of many users with common restrictions easier, it is possible to create user templates.
Single users and user templates are created using the ConsoleOne utility.
Lesson 14 – Novell NetWare 6.021
Creating Groups
Groups are created to provide two or more users access to shared resources, rather than repeating the same access rights for multiple users.
Groups are created using the ConsoleOne utility.
Lesson 14 – Novell NetWare 6.022
The Netware Security Model
Login Security—Used to ensure that only authorized users have access to the network.
NDS Security—Used to control users’ abilities to view, access, create, or modify objects and their associated properties.
Lesson 14 – Novell NetWare 6.023
Login Security
User account restrictions can be set up to make sure that the user logging onto the network is authorized to do so.
Intruder detection works at the container level by setting a limit on the number of incorrect login attempts that can be made by a user within the container.
Lesson 14 – Novell NetWare 6.024
NDS Security
All objects have a property called the Access Control List (ACL). This contains the names of users, groups, or containers that have been given access rights to that object.
There are two categories of user rights:– Object rights– Property rights
Lesson 14 – Novell NetWare 6.025
Object Rights
Right Ability
Supervisor Grants all access privileges
Browse Grants the right to see objects in the directory tree
Create Grants the right to create objects in the directory tree; only for container objects
Delete Grants the right to delete an object from the directory tree
Rename Grants the right to rename an object in the directory tree
Lesson 14 – Novell NetWare 6.026
Property Rights
Right Ability
Supervisor Grants all rights to the property
Read Grants the right to view the stored values in the properties field
Compare A special type of Read property that allows the user to compare the value of a property to a fixed value returning the value of True or False without revealing the contents of the property
Write Grants users the right to add themselves as a value of the property
Add Self Grants users the right to add themselves as a value of the property
Lesson 14 – Novell NetWare 6.027
Summary
Novell has a global database of network objects and users called NDS to which all servers on the network have access.
The NDS database contains three major objects: the root object, container objects, and leaf objects.
ConsoleOne is the NetWare administrative tool that provides a single point of administration.
The main components of the NetWare file system are volumes, directories, and files.
Lesson 14 – Novell NetWare 6.028
Summary (continued)
To establish security in a network environment, every user needs to have a unique logon name.
Because some of the user object properties are common to many users, you can create User Templates within each container object to make creating user objects simpler. Rather than repeating the same access rights for multiple users, you can create a group with access rights.
A NetWare administrator must ensure that the network is properly secured, including limiting users of the network to the resources they need to accomplish their daily tasks.
Lesson 14 – Novell NetWare 6.029
Summary (continued)
NDS Security allows users to view, access, create, or modify objects and their properties. All objects have an ACL property which contains the names of users, groups, or containers that have been given access rights to that object.
Rights are divided into object rights and property rights.
Effective rights are the actual rights a user has to an object; they declare what actions a user can perform with NDS objects.
