Network server configuration and application

As the network gradually spread to small and medium-sized enterprises and even families, people are no longer satisfied with enjoying all kinds of network services at the front-end. Instead, they want to explore how backend servers provide network services. At the same time, you need to understand network management and become a network service provider with more and more people. You need to complete the transition from the network service end user to the network service provider role.

Learn about Internet/Intranet services

* Internet/Intranet service type

With the development of Internet/Intranet, its service forms are also increasingly rich. Here we will give a brief introduction to the main service types:

(1) WWW service. WWW refers to the World Wide Web. It is an Information Query Tool Based on HyperText. WWW organically binds the data information of different web sites on the Internet around the world, and provides a friendly query interface through a Browser.

(2) File Transfer Service (FTP ). File Transfer refers to the transfer of files between hosts on the computer network. It is supported by the network communication protocol FTP (FileTransferProtocol. As long as both computers on the Internet support the FTP protocol, online users can transfer files from one computer to another.

(3) email service (E-Mail ). Electronic mail is also called e-mail. It is a service used to send and receive information between users or user groups over a computer network. It is also one of the most widely used and popular services on the Internet.

(4) directory service. Directories provided for common users on the Internet are mainly used to search for users and business partners worldwide. Users can access the Directory Server to query various public information of online users.

(5) Network News Service (USEnet ). NetworkNews is also known as USENET. It is an invisible network for exchange of opinions between Internet users who share common interests. It is equivalent to a global bulletin board system.

* Internet/Intranet and customer/server systems

Customer/service system (C/S) refers to the network computing mode in which tasks are distributed between users and servers on the computer network. The client requests information or services from the server, and the server responds to the requests from the client. The core of the Internet is the service, which provides users with a variety of services to meet the needs of Internet users. Internet is a huge customer/server system, and each service needs to be accessed by the corresponding customers.

DNS Service

* DNS Overview

DNS is a system that uses the C/S mechanism to convert names and IP addresses. By establishing a DNS database, you can record the ing between host names and IP addresses on the server side to provide IP Address Resolution Services for the host on the client side. As shown in, the structure of the entire Internet DNS domain name system is like an inverted tree with a clear hierarchy. The root domain is located at the top. There are several top-level domains under the root domain, and each top-level domain is further divided into different second-level domains. The second-level domain is further divided into sub-domains. hosts may exist under the sub-domain, you can also perform molecular domains until the host is used.

DNS Domain Name System Structure

* Create and manage DNS regions

DNS regions are classified into two types: Forward search regions, that is, databases with names to IP addresses, which are used to convert names to IP address services, and reverse search regions, that is, the database from the IP address to the name, which is used to provide the service to convert the IP address to the name.

* DNS Security

The Windows2003DNS server can prevent DNS structure attacks by setting security functions.

Website creation and management

* New Features of IIS6.0

As Web servers are increasingly targeted by hackers and worms, IIS has become the primary concern of Microsoft's trusted computing program. Therefore, IIS6.0 is completely redesigned to achieve default security and design security.

* Use IIS6.0 to create a Web site's Virtual Host

There are three virtual technologies available for creating multiple WEB sites to achieve this goal: additional port numbers, multiple IP addresses, and different host headers. These three virtual technologies have their own merits and are applicable to different application scenarios.

* IIS6.0 website management and Configuration

Each website must have a home directory. The main directory is located in the center of the published webpage, including the homepage or index file and links to other webpages on the website. The main directory is the "root" directory of the website, is the domain name or server name mapped to the website. When you use a URL without a file name to access the WEB site, the request directs to the main directory. (1) set the location of the main directory. First, you must determine the location of all the directories on the website and select the "directory on this computer" option to indicate that the contents of the home directory are located on the server. (2) set the default document for the WEB site. In the website property Settings dialog box, click the document tab. In the Settings dialog box, you can set the default document for the WEB site.
