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.

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 DirxmlDrivers 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)

Networking Hardware

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

The Theory Before You Install

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.
