Today, we have entered a new information age. The product of the network information age has gradually formed a culture with distinctive characteristics of the times. With the continuous development of information technology, information technology courses have been offered in ordinary high schools. Computer network is an important knowledge module in information technology teaching. It is closely linked with the learning and life of middle school students, both now and in the future. Chapter 4 of the High School Information Technology Teaching Material comprehensively and systematically introduces the basic network knowledge, in which Internet application is the main teaching content, therefore, in teaching, we should take "ways for students to obtain, exchange, and publish information on the Internet" as the teaching goal. Due to regional and economic restrictions, some school data centers do not have Internet access conditions. However, if you are interested in information technology courses, you cannot use "no Internet access" as an excuse, the content of this chapter is included. How can we solve this conflict?

In chapter 4, Internet applications mainly include obtaining information on the Internet, exchanging information on the Internet, and publishing information on the Internet. My teaching is carried out in the LAN and has achieved good results. The following is an example of my operations:
Preparations
To achieve these three teaching objectives, the first step is to build a site in your own LAN. So how to install a home in the lan? The key is to deal with your server. The specific operations are as follows (taking the practice of the student data center in our school as an example ):
The server uses Windows NT and requires the installation of Web Services, DHCP services, DNS services, and TCP/IP protocols. The server name is ntserver and the IP address is set to 192.168.0.1.
1. Configure the DHCP service
The DHCP server automatically assigns an IP address to the client. Therefore, the first management task is to create a scope for the IP address range. The procedure is as follows:
① Click [start] → [Program] → [Administrative Tools] → [DHCP manager] to enter the DHCP management tool.
② In the "DHCP server" list in the "DHCP manager" window, select the server for which you want to create a scope. Select the "add..." command in the "server" menu, and enter the IP address of the server, such as 192.168.0.1.
③ Double-click the newly created server. In the scope menu, click Create to open the create domain dialog box. Set the IP address range to 192.168.0.2 -- 192.168.0.250. Next, add exclusion and set the lease term. The default value can be used in these two steps.
④ Activate the DHCP scope. You can click "Activate" in the "Scope" menu ".
2. Configure the DNS Service
The DNS server is used to convert IP addresses and domain names.
① Click [start] → [Program] → [Administrative Tools] → [DNS manager] To Go To The DNS management tool.
② Select the "new server" command in the "DNS" menu, and enter the server name in the dialog box, for example, 192.168.0.1
③ Right-click the new server and select "new region ...". In the displayed dialog box, select "Main" as the region type and click "Next ". Enter zszxit.com in the domain name. For other items, you only need to use the tab key to skip them one by one. The system will automatically give the default name and confirm it.
④ Right-click the newly created primary domain zszxit.com and select "New Host ". In the displayed dialog box, enter the host name WWW and the corresponding IP address 192.168.0.1.
With the above preparations, we only need to set the server to implement internet teaching in our own LAN.
2. obtain information on the Internet
(1) Installing a home in the LAN -- Building a Teaching Site
To create a teaching site, you must configure Web services. To configure web services, you must first configure IIS to Support Web Services. IIS (Internet Information Server) is automatically installed with Windows NT, but its version is low. We recommend that you upgrade it to version 4.0. IIS has set up a "Default web site" in the system. Its main directory is C:/inetpub/wwwroot, and the primary page is default.htm. We can set it as needed.
In Windows NT, you can use IIS to publish a web site in multiple ways. Of course, you must prepare the documents to be published before publishing any site. The simplest method is to copy the Web document to the main directory c:/inetpub/wwwrootand the main page ghost file name is default.htm. To ensure the orderliness of management, we create a folder D:/itweb in the root directory of drive D as the main folder of the website, put the pre-designed website content into the folder, and then add the site, the procedure is as follows:
① Open Internet Service Manager, right-click the server name, and choose [add] → [web site.
② Click Next, enter the description text of the new site, such as "it", and then click Next to plan the user connection settings. Set the IP address to 192.168.0.1, And the TCP port uses the default value 80.
③ Click Next and enter your home directory path, such as D:/itweb. The default value will be used in subsequent steps.
Now, you have created a web site for teaching. Enter a domain name, such as www.zszxit.com, or an IP address, in the browser address of any workstation. For example, 192.168.0.1, you can browse your site. As long as you link the required information to the page of your site, you can obtain your information for teaching.
(2) Use Serv-U to build your own powerful FTP Server
To implement FTP teaching, you must build your own ftp server. I implemented it through server-u. The specific operations are as follows:
First, install the original software and hand-made patches. This process will not be said much, and no one will. After the installation is complete, the program runs automatically. You can also choose to run it from the menu.
1. When you run the program for the first time, the setting wizard window will pop up, and you will be taken to complete the initial setting;
2. Click "Next" and the "show menu image" window appears. Ask if you want to display a small image in the menu;
3. Click "Next". This window is the first time you run the FTP server locally. You only need to "Next;
4. Enter your IP address, for example, 192.168.0.1;
5. Click "Next" and ask you to enter your domain name here. If you have one, for example, www.zszxit.com, you can enter either of them;
6. Click "Next" and ask if you want to allow anonymous access. Generally, anonymous access uses the username anonymous to log on without a password. Of course, if you want to create a membership zone or something, you should select "no" to prevent anyone from logging on. Only authorized users are allowed. Here we enter "yes ";
7. Click "Next" and ask the anonymous user about the directory when logging on to your computer. You can specify an existing directory on the hard disk, such as E:/itftp;
8. Click "Next" and ask if you want to lock the directory. After the directory is locked, anonymous login users will only consider that the directory you specified (E:/itftp) is the root directory, that is to say, he can only access the files and folders in this directory, but cannot access the files outside this directory. For anonymous users, generally, "yes" is entered ";
9. Click "Next" and ask if you want to create a named account. That is to say, you can specify a user to access your FTP using a specific account. This is useful for creating a membership zone, you can create an account for each user. If the permissions of each account are different, you can restrict the rights of each user by using different programs. Here, select "yes ";
10. Click "Next". enter the name of the account to be created, for example, manager;
11. Click "Next". Enter the password, such as 123;
12. Click "Next" and ask what the logon directory is. Step 1 and Step 1
Example: e:/itftp;
13. Click "Next" and ask if you want to lock the Directory, which is the same as step 1.
Select "no ";
14. Next, you will be asked about the administrator permissions of the user you created this time. There are several options:
You have no permissions. The Group Administrator, domain administrator, read-only administrator, and system administrator have different permissions. Select "System Administrator ";
15. In the last step, click "finish" and you will be OK. What do you need to modify,
You can click "previous" or enter the Serv-U administrator to directly modify the settings. Now, we have created a domain www.zszxit.com, two users, one anonymous and one manager. After the configuration is complete, we will enter the main interface of the Serv-uadministrator, each topic is displayed in the left pane, and the option of each topic is displayed in the right pane. The following describes the settings.
1. In the figure, we can artificially control the running or stopping of the Serv-U engine;
2. "License". If you have bought a registration number for US dollars, you can enter it here;
3. "Settings". This setting is for "local server.
4. "activity", which records the user activity logs, activity logs of blocked IP addresses, and task logs;
5. "Domain", which contains the users, settings, and domains you set up according to the wizard at the beginning.
Figure Serv-user administrator's main interface
6. "Domain> group", we can create some easy-to-manage groups, and then
Users of the first type are in the same group. 7. In "Domain → user", you can see the two accounts we created at the beginning, one anonymous and one manager.
With this, we can implement FTP teaching. Create a directory itftp on the E disk and put the files you need to download into it, in this way, you can enter a ftp://www.zszxit.com In the IE Address Bar of any workstation to log on to the local server anonymously. Of course, we can also log on to the FTP server as different users. Open Server-u, create a user student in the domain www.zszxit.com, enter the password, select the Directory Access tag, and select Add. The path is E:/itftp, the access permission is set to read, write, and allow Directory Creation and deletion, so that you can log on to your FTP server as student to upload and download files.

(3) using cool search maker as a search engine on your own site
Search engines are the most commonly used tools for accessing the Internet. They can be divided into two types: popular search engine sites, such as Sohu, Yahoo, and Google, the other is the search engine in the site. Sometimes a user browses your website to get a small amount of information and does not want to browse your site. If you have a "intra-Site Search Engine", it will undoubtedly be very convenient for users. The following describes the cool search maker, a production tool for "Site Search Engine.
Software Installation
This step is relatively simple and I believe no one will.
Create a local search engine File
(1) Add a local site
Click "folder" to select the folder where your local site is located,
At this time, cool search maker will automatically read the information of all files in this folder.
(2) generate a search engine script
Click "build". The software will automatically generate the search.html file. The default generated path is under "output" of the software installation directory.
(3) test
Click "run" and the software will automatically open the web page search.html. This test page is very simple, with only one input column and one search button. You can enter any text on any webpage on your website for testing. The software will automatically generate a result page similar to Google.
Add a search engine to your website
Copy search.html to the root directory of your website and add a "intra-Site Search" hyperlink to your homepage. So far, all your intra-site search engines have been completed.
3. Exchange information on the Internet
(1) Easy E-mail
Currently, almost all websites have mailbox applications. How can I implement e-mail in my own lan? Here we will introduce a very good tool, webeasymail.
1. installation and configuration
(1) install webeasymail to a directory on the server (for example, D:/itweb );
(2) Open "Internet Service Manager ";
(3) Add the virtual directory "webeasymail" under "itweb", which actually points to the web directory under webeasymail (for example, D:/itweb/webeasymail/Web );
(4) The Startup File is default. asp (Note: The Global. Asa file must be located under this "virtual directory)
2. Domain Name settings
(1) domain name setting is to set the domain name after the user's email address "@". The default domain name of the system is: system. mail, when a new user is added, such as the user name is: ABC, the user's default mail address on the Web easy mail server is: abc@system.mail
(2) Open "webeasymail" in "start" → "program" → "webeasymail", and add a new domain name (such as zszxit.com) to "Domain Name management ). In this way, you can use the new email address, such as the abc@zszxit.com ).
3. Set a hyperlink on the homepage
Set the hyperlink "email Center" to webeasymail on the homepage of your website. Then, you can apply for a mailbox and use the mailbox by opening the "email Center" option on the homepage.
After applying for multiple accounts, if you want to send and receive emails, you have to open each mailbox, Which is troublesome. In this case, you can use Outlook Express to send and receive your own emails. Of course, it should be noted that the student should be notified of the IP address (192.168.0.1) of the webeasymail server, so that they can make corresponding settings in the mail sending and receiving software such as outlook.
(2) QQ in the LAN is also crazy
Currently, almost no one on the internet knows QQ, and no exception is given to students. Naturally, they are curious about QQ's chat tool. Since we cannot access the Internet's Lan, naturally, QQ cannot be used, but it does not matter. We can implement it through other software. That's freeicq. This is a great LAN calling software! It is a set of Instant Messaging Software mainly for LAN, including server and client. It uses an interface similar to OICQ, which is easy to operate and has low Computer Configuration Requirements and easy to install. You can quickly create an instant messaging system without having to set up it.
You only need to install freeserver on the server and ficq on the client. Of course, you can control it through the software on the server. You can use it only after the software on the server is started.
Try it now. It's good!
(3) You can chat with me.
In addition to the e-mail and QQ communication tools, you can also create your own chat room.
(1) copy the file to a directory on the server (for example, D:/itweb/liaotian );
(2) Open "Internet Service Manager ";
(3) Add the virtual directory "liaotian" under "itweb". The virtual directory actually points to the folder where the files are stored (for example, D:/itweb/liaotian)
(4) set the "chat room" hyperlink on the homepage of your website. The link address is "liaotian", so that you can chat online by opening the "chat room" on the homepage.
(4) BBS in the LAN
BBS is also an indispensable landscape in information exchange. I use freebbs to implement forums in the LAN.
Software Installation
(1) decompress the ZIP file to a directory (for example, E:/itweb/BBS ), create a virtual directory (such as/BBS) with read and script attributes for this directory in the IIS management program)
(2) Move bbs. mdb to another directory and create a virtual directory (such as/BBS/data) that cannot be read or written)
(3) Open the common. inc file in notepad. The last line is:
Conn. Open "driver = {Microsoft Access Driver (*. mdb)}; DBQ =" & server. mappath ("/BBS") & "/BBS. mdb ;"
Replace the section in mappath () with the web path of the database file you just created.
For example, on your machine, the BBS installation path is
Http://www.yousite.com/yourname/bbs/
The virtual directory created for the database is
Http://www.yoursite.com/yourname/bbs/data/
Replace the above "/BBS" with "/yourname/BBS/Data". The changed statement is as follows:
Conn. open "driver = {Microsoft Access Driver (*. MDB)}; DBQ = "& server. mappath ("/yourname/BBS/Data") & "/BBS. MDB ;"
(4) At last, you add a hyperlink to the "online forum" on the homepage of your website. The link address is BBS, so that you can use freebbs.
Use of software
Preparations for the server
Log on to the system as an administrator (Default User Name
And the password are: bbsadmin) after the successful entry into the main page;
Open up a new discussion area. Select "open new category" and enter a new discussion area
Name and description
(3) Open up a new layout. Go to a discussion area and select "apply for a new version ".
Specific Layout
Client usage
In addition to the Administrator bbsadmin, before you use bbsadmin for the first time, you must first
To register, select "User Registration" and log on to the system after registration. You do not need to register, log on to the system directly using any unregistered name (without a password ).
(2) After "system Logon" is completed, you can go to the relevant "discussion area/layout"
Post.
(3) query the posts. Select "query" on the homepage ".

4. Information publishing on the Internet-the free home page in the LAN
The Internet information publishing in the textbooks mainly refers to the production and uploading and publishing of webpages. How can we implement a free homepage in the lan:
1. Create the following directory structure on disk D :.
D:/WebPages
| -- G101
| -- ST01
| -- ST02
:
Webpages is the total directory of the student folder, g101 represents the folder of the First Class (class 1), and so on ...... stxx stores the folder of the webpage files for the students.
2. Specify a private folder for each student based on the student ID. For example, if Li Lin's student ID is 1, set ST01 to Li Lin's private folder.
3. Open Server-u, create a user webpages in the domain www.zszxit.com, set the password, select the Directory Access tag, and select Add. The path is E:/webpages, the access permission is set to read, write, and allow Directory creation, and cannot be deleted. In this way, students can log on to the server as webpages to upload webpages.
4. configure a personal webpage for students
Configuring a personal webpage for a student is to specify a virtual directory for the student's webpage folder. The procedure is as follows:
① Open Internet Service Manager, right-click the site it you have created, and select [new] → [virtual directory.
② Click Next and enter the name of the student you want to work on the web site. For example, if the account of student 1 is Lilin, enter Lilin as the site name.
③ Click Next and specify the real path D:/WebPages/g001/ST01 of the student's webpage directory on the 1st. After you plan the access permission, complete the settings. In the address bar of the browser, enter.
How can we easily implement the free home page in the lan ?!
At this point, I am sure you have a little bit of an eye on how to implement internet teaching in the LAN? Looking at the site built by myself, isn't it a little float? It seems that you are also an omnipotent network administrator. Of course, I believe that your continuous efforts can make your "home" more colorful and have unlimited charm!
