What is a Microsoft Internet What is a Microsoft Internet Information Server? Information Server?

It is Microsoft’s Web server that allows for the management of Web-related applications, files and data.

What is a Web Server?What is a Web Server?

A Web server is a specialized program that uses the client/server model and the World Wide Web's Hypertext Transfer Protocol (HTTP) to present files in the form of Web pages to the users.

Example of the Use of a Web Example of the Use of a Web Server Server

When we type in: www.calstatela.edu/ats/cbt.htm, we are directed to the web server with the domain name www.calstatela.edu.

The web server then finds the ats directory and the cbt.htm file. It then forwards the file directly back to us.

IIS Installation ProcessIIS Installation Process There are a number of ways to install IIS 4.0. You can download the Windows

NT Option Pack from the Internet, or your can install it from CD.

To download the Option Pack from the Internet, you use the URL shown here: http://backoffice.microsoft.com/downtrial/optionpack.asp

To install the Option Pack from the CD, you insert the CD in the drive and run the appropriate setup.exe.

• The minimum installation program is designed to conserve disk space on your system.

• The typical installation installs all the components of IIS included in the minimum installation. In addition, it installs the rest of the optional IIS components. Included in the typical installation is the FTP service, the Internet Service Manager (HTML), and help on server administration, content management, and content development.

• The custom installation allows you to choose which IIS components you want on the computer, apart from the components that are required and selected by default.

• Let’s choose the Custom installation, which allows you to select any combination of components in addition to the IIS component that is required to run the IIS server.

•If you are using IIS on an intranet, you can copy the unattend.txt file from the Option Pack CD to a folder on the local computer (The unattend.txt file is located on the CD in the CPU_Type/inetsrv/directory, where CPU_Type is the processor on the computer where IIS will be installed.) This file allows you to perform unattended installations from that folder. This is useful for performing installations without having to remain at the computer and step through the installation options.

• To start the unattended setup, you either place the CD in the CD drive, or make a network connection to the CD drive containing the Option Pack CD. You then copy unattend.txt to your local hard disk and make any necessary changes to install the appropriate components.

• At a command prompt, you change to the folder on the CD containing setup.exe, then enter the following path: setup/u:<full path to Unattend.txt>. For example, if the file located in the temp directory on the C drive, you type: setup/u:c:\temp\unattend.exe

By Ben Lee 57

-a Lists the remote computer's name table given its host name.

-A Lists the remote computer's name table given its IP address

specified in dotted decimal notation.

-c Lists the contents of the NetBIOS name cache, with the

IP address of each name.

-n Lists local NetBIOS names. In this listing, "Registered"

indicates that the name has been registered on this network

node, either by b-node broadcast or by a WINS server.

By Ben Lee 58

-R Reloads the LMHOSTS file after purging all names from

the NetBIOS name cache.

-r Lists name resolution statistics for Windows networking.

On a computer configured to use WINS, this option returns the

number of names resolved and registered broadcast or WINS.

-S Displays both workstation and server sessions, listing

the remote hosts by IP address only.

-s Displays both workstation and server sessions.

It attempts to convert the remote host IP address to a name

using the HOSTS file.

By Ben Lee 59

NbtstatNbtstat

When adding more than 25 dialout devices under Windows NT 4.0 RAS, the NBTSTAT command will return the following message: – Unable to access NBT driver; Unknown Error

This problem is because NBTSTAT is not reading the entire contents of a registry key.

By Ben Lee 60

ARPARP

ARP (Address Resolution Protocol) is a protocol for mapping an Internet Protocol address (IP Address) to a physical machine address that is recognized in the local network.

The most common level of IP in use today, an address is 32 bits long.

By Ben Lee 61

How ARP WorksHow ARP Works

When an incoming packet destined for a host machine on a particular local area network arrives at a gateway, the gateway asks the ARP program to find a physical host or MAC address that matches the IP address.

By Ben Lee 62

RouteRoute

The route table controls any routing decisions made by the hosts on a network

You can display the route table using the Route Print command.

RouteRoute

TracertTracert

Examine the route between two nodes on a network

Determines the route by sending the first echo packet with a TTL of 1 and incrementing the TTL by 1 on each subsequent transmission until the target responds or the maximum TTL is reached.

NslookupNslookup

Lets an Internet server administrator or user enter a host name and find out the corresponding Internet Address. It will also do reverse name lookup and find the host name for an IP address you specify.

By Ben Lee 71

NslookupNslookup

For example, if you entered "whatis.com", you would receive as a response our IP address, which happens to be :

199.45.146.176Or if you entered "199.45.146.176", it

would return "whatis.com".

Introduction Introduction

Internet Information Server can be used for interactive applications and scripts for your website.

IIS can be used for CGI Scripts and ISAPI Applications.

CGICGIWhat is CGI?

By Javier Ek 77

CGICGI

By Javier Ek 78

CGICGI

CGI script conforms to CGI standards. Scripts or programs can be written in any language

for applications to be executed on a system. These languages can be C++, PERL, Visual Basic,

and NT Batch Files. Programs such as VB and C++ need to be

compiled in order to work. Scripts do not need to be compiled and are much more portable.

By Javier Ek 79

CGI – Security IssuesCGI – Security Issues There are several security issues in regards to

CGI. Intruders and hackers can manipulate CGI script

to access sensitive information such as passwords and registry files.

They can also use CGI script to run system commands. This risk can be reduced by having experts write the scripts and keeping them in one single directory with only an administrator access.

By Javier Ek 80

CGI - RequirementsCGI - Requirements

To write CGI Scripts a working knowledge of HTML and HTTP protocol is needed.

By Javier Ek 81

ISAPI ISAPI What is ISAPI(Internet Server Application

Program Interface)?

By Javier Ek 82

ISAPIISAPIApplications that use ISAPI have

executable code that reside in NT DLL(Dynamic Link Library).

There two areas of development are applications and filters.

ISAPI applications are known as Internet Server Applications(ISAs)

Active Server Pages(ASPs)Active Server Pages(ASPs)

Active Server Pages are a scripting environment that overcome the limitations of CGI.

With ASP you can combine HTML, scripts, and text on web pages.

The built-in Active X components can be used to perform dynamic tasks, such as connecting to a database or performing calculations.

By Javier Ek 86

ASPASP ASP eliminates the need to learn a full programming language or

compile programs separately. Any scripting language that follows the ActiveX scriting standard such

as Vbscript or Javascript. To use other languages such as PERL, Python, or REXX you need a

separate scripting engine from a third party developer.

ASP SecurityASP SecurityASP offers the most security of the three

methods.

By Javier Ek 89

ASP AdvantagesASP AdvantagesASP applications are easy to modify and

develop.An ASP file is simply a text file that can

contain HTML tags and embedded script commands.

ASP uses ActiveX Control which are essential to dynamic web pages.

By Javier Ek 90

SummarySummary

Internet Information Server can be extended to use CGI, ISAPI, and ASP for web applications.

CGI is the most common but ISAPI, and ASP are also used.

ASP offers several advantages over CGI in terms of security, capabilities, and browser compatibility.

Internet Service Manager can be used to specify a starting point directory and to configure your application.
