Implementing a network

A Vizioneer Studios Production

 You Will Learn:
 Network Options
 Network Requirement
 Installing A Network Server

 1. Practice active management.
 2. Use managed wireless products.
 3. Prioritize usage.
 4. Develop a guest policy carefully.
 5. Build security from the start.

 One Of The First Duty Would Be Installing A
Network
 After All
 If Zare Ez No Network
 Zare Ez No Needz For You

 Installing A Network Includes:
 Choosing The Right Type Of Network (i.e. Linux, Microsoft)
 Choosing Between Peer To Peer and Client/Server n/w
 Purchasing:
 Software Hardware
 The Server NOS
 Client Desktop System

 By Now You Should Know The Difference Between
A P2P Network and A Server Based Network
 You Should Be Able To Choose Which Type Is
Better Keeping Their Advantages And
Disadvantages In Mind

 With Peer To Peer Networks:
 The advantage Is That You Don’t Need To Purchase
Servers Hardware And The Network OS
 On The Down Side However, The Network Is
Limited To Ten Computers Max

 With Server Based Networks:
 You Can Use A Larger Amount Of Computers On
The Network
 However There Is The Cost For The Server And It’s
OS
 Also You’d Need To Purchase A Client Access
License

 A Client Access License Is Needed To Allow Your
Clients To Connect To The NWOS
 Note Though, A CAL Is Needed For Each Client
That Is Connected To The Network

 MS Networking
 When It Comes TO Networking, MS Networks
Have A Big Market Share.
 The Most Popular Server Being MS Server `03
 But MS Server `08 Is The Latest.

 MS Networking
 When installing A MS Server You Have A Number
Of Choices To Make. Such As:
 Installing It As A Stand Alone Server
 Installing It As A Domain Controller
 Installing It As A Member Server

 A Standalone Server Is One That Has A Local Secure
Accounts Manager database (SAM database) Similar
To That Of A WinXP System.
 The SAM Database Is A Database Of Accounts That
Resides On The Local System.
 Its Used To Access Resources Only On The Local
System

 A Domain Controller (DC) Is A Server That Has Active
Directory (MS Directory Service) Installed.
 The Active Directory Database Allows You To Access
Resources Across The Network.
 Along With Dc Are 3 Terms That Must Be Known:
 Domain
 Tree
 Forest

 A Domain Is A Logical Grouping Of Computers And
Resources.
 Its A Security Boundary And A Replication Boundary.

 Trees Are A Hierarchy Of Domains That Have A
Contiguous DNS Namespace.
 Example A Domain May Have A Child Domain For
Certain Areas That Connects To It
CCGDT
Public
Library
College
Library

 A Forest Is Just A Collection Of One Or More Trees.
CCGDT
Public
Library
College
Library
Lime
Public
Library
College
Library

 A Member Server Is A Machine That Is Part Of A
Domain, Or A Member Of The Domain While Being A
Resource To Other Computers.

 Novell’s Directory Service Is Currently Called
“Edirectory” Is Similar To Active Directory In That It Is
A Database Of Network Accounts That Is
Automatically Synchronized With Other Servers.
 One Or More Netware Servers Sharing The Same
Edirectory Database Is Called An Edirectory Tree.

 One Major Benefits Of Edirectory Is That You Are Not
Limited To Installing It On Netware Servers.
 It Can Be Installed On Netware Servers, Windows
Servers And Unix & Linux Servers!
 The Updated Version Netware 6.5 Includes Dirxml
Drivers Which Gives You The Freedom Of
Synchronizing User Information With Any Other Type
Of Directory Service

 But Novell Had Been On The Constant Move In Terms
Of Progress.
 As A Result Of Their Progress, They’ve Changed Their
Names A Few Times.

 The First Name Was Bindery.
 Bindery Was Bout During Netware 2.X And
 With Bindery, The Network Account Database Is
Stored On Each Server
 The Down Side However Was That It Was Not
Synchronized With Any Other Servers

 Next Came Novell Directory Services.
 NDS Came About For NetWare 4.x and 5.x
 This Update Repair The synchronization between
servers Deficiency.

 Finally There Is eDirectory.
 NDS Lacked Sufficient Storage And eD Gave Them
That Storage.
 eD supports efficient storage of billions of objects
 As A Result almost every aspect of Novell environment
configurations is stored in eDirectory.

 Linux Is Starting To Command A Lot Of Attention In The
IT Industry Because Of Its Reliability And Its Secure
Architecture
 Linux (And UNIX) Environments Can Store User Account
Information In Files
 For Example: /Etc/Passwd Holds User Account
Information
 /Etc/Shadow Holds Encrypted User
 Passwords,
 And /Etc/Group Holds Group Membership Information)

 The First Thing That You Will Need Is Hardware.
 In Each Of The Systems Or Hosts That Will Participate
On The Network A Network Interface Card Is
Mandatory.

 You Will Also Need To Have:
 A Hub Or A Switch (This Act As A Central Connection
Point For All The Systems.)
 Router (This Aids In Sending Data To Another
Network)
 More Than 1GB RAM
 Multiple CPUs On The Motherboard (Optional)

 It Is Extremely Important To Understand What The
Network’s Software Requirements Are.
 There Are Four Software Components You Will
Certainly Need Somewhere On The Network.

 Service
 A Service Is Typically The Reason For The Network
 It Is What Is Being Provided To Clients On The
Network
 For Example, File And Printer Sharing Services,
 Even Web Services

 Client
 A Client Is A Piece Of Software That Connects To The
Service And Makes The Network Request.
 For Example A Web Browser (Client) Makes
 Requests To A Web Server (Service) For Different Web
Pages On The Web Server.

 Protocol
 A Protocol Is The Networking Language That A
System Uses To Send The Request From The Client To
The Service.
 If You Want Two Systems To Communicate, They Will
Obviously Need To Speak The Same Language
(Protocol),

 Network Card Driver
 Without The Network Card Driver, The NC Is Just A Thing
Sitting In Your Motherboard
 In Order For All Of This To Work, You Will Need To Make
 Sure That The Network Card Driver Has Been Installed On
The System
 This Is The Only Way That That The System Can Send And
Receive Data

 Server Name
 You Will Need To Decide What The Name Of The
Server Will Be Because Clients Will Connect To The
Server By Name When Accessing Folders And Printers.

 Domain Name
 If Your Server Will Be Joining A Domain, You Will
Need To Type In The Name Of The Domain.
 Also If You Are Joining A Domain, You Will Also Need
To Know The Username And Password Of The
Administrator Account That Has Permission To Add
Servers To The Domain.

 Server As Domain Controller
 You Will Need To Know Before You Start The
Installation Whether Or Not The Server Will Be A
Domain Controller.
 If The Server Is To Be A Domain Controller, You Will
Need To Install It As A Standalone Server And Then
Run dcpromo.exe To Promote It To A Domain
Controller

 Hardware Support
 Make Sure That Your Server Hardware (Network Card,
Video Card, And What’s Now) Will Work With The
Server Operating System By Checking Out The
Windows Server Catalog.
 The Link Is Usually

 Partition Setup
 Plan Your Partition Strategy Before The Installation So
That You Are Prepared.
 During The Installation, You Will Have The
Opportunity To Create And Delete The Partitions On
The Hard Disk Of The Server.
 Plan Carefully

 File System
 After Partitioning The Disk, You Will Need To Format
The Partition With A File System Such As FAT32 (File
Allocation Table) Or NTFS (New Tech File System).
 For The Best Security It Is Advised That You Should
Always Go With The NTFS File System On Microsoft
Servers

 Licensing
 When Installing A Windows Server, You Will Have To
Choose Either Per Seat Or Per Server Licensing.
 With Per Server Licensing, You Obtain
 A Client Access License (CAL) For Each Connection To
The Server.
 With Per Seat Licensing, You Purchase A License For
 Each Individual Client That Will Access The Server

 With Installation There Are Two Phases To The
Installation Process:
 The First Is The Text-mode Portion Of The
Installation, Where You Partition The Disk And
Format The Partition. Then The Setup Files Are
Copied From The CD-ROM To The Hard Drive.

 The Second Is The GUI-mode Portion Of The
Installation Will Ask For Information Such As Your
Product Key Computer Name, And Administrator
 Password.

 Wi-fi Networks Don’t Stay In Top Condition On Their
Own.
 The Inevitable Moving, Additions And Changes Of
People, Furniture And Everything Else Within An
Organization Will Cause The Network To Degrade
Over Time.
 As A Result Providing Less-than-optimum Service To
Users.

 Wi-fi Networks Are Amazingly Fault-tolerant.
 They Can Survive The Loss Of Access Points And The
Addition Of Interference Without Registering
Significantly Perceptible Effects.

 That Being Said Though, Problems Might Go
Unnoticed Without Active Monitoring.
 Good Network Management Practices, Including The
Regular Scanning Of Logs And The Active Monitoring
Of Devices And Usage.

 Airespace, Aruba and Trapeze developed technology
that treated the entire wireless network as a single
entity, rather than as a series of individual APs (Access
Points)
 Thus was born the fully managed wireless solution.

 The Technology Today Can Handle Issues Such As:
 Mobility,
 Keeping An IP Address And Connection Alive While A
User On A VoIP Call Walks Between Rooms, Floors And
Even Buildings.

 It Is Important Though That The Network Team
Should Be Careful To Distinguish Between Fully
Managed Solutions And Those That Only Offer
Configuration Control And Log Collection.
 Simply Capturing The Configurations Of Each Ap And
Pushing Changes To Them Uniformly Is Not True
Wireless Management.

 In The First Few Days After A Network Is Turned On,
The Smartphones Of At Least 10 To 20 Percent Of The
People In The Building Will Connect Automatically.
 These Devices Will Consume Bandwidth Even When
No One Is Using Them.

 If The Building Is On A High School Or College
Campus, That Figure Will Be Closer To 80 To 90
Percent.
 In Other Words, A Wireless Network Can Reach Near
Capacity Even When No One Is Actively Using It.

 The Solution Isn’t To Prohibit Casual Use, But Simply
To Make Sure That Mission-critical Applications
 By Using Management Configuration, Firewalls Or
Wi-Fi Multimedia (WMM), It’s Possible To Throttle
Bandwidth.

 Accommodating Guest Access To Wireless Networks Is
Generally Considered A Requirement For Enterprise
Wireless Installations.
 Guests Commonly Have A Legitimate Need To
Connect To The Internet While Visiting An
Organization

 Therefore Guest Policy Must Balance Its Requirements
For Accountability And Prevention Of “Drive-by”
Connections.
 The Entire Goal Should Be To Make Guest
Connections Simple And Quick.

 Security Managers Tend To Be Fairly Suspicious Of
Wireless Networks.
 If User Credentials Are All That Is Required To
Connect, Then Confidential Info Would Only Be A
Stolen Set Of Credentials Away

 While Many Techniques Exist To Increase Overall
Security For Wireless Users, It Pays To Have The
Organization’s Security Teams Involved From The
Beginning.
 Doing So Will Make It Possible To Incorporate Their
Requirements Into The Architecture Design And
Product Selection Phases Of The Project.
