Today, we have entered a new information era. The product of this era of network has gradually formed a culture with distinctive age. With the continuous development of information technology, there is currently this course in information technology. Computer networks are more important knowledge modules in information technology teaching. Whether it is still in the future, it is closely linked to middle school students. The fourth chapter of High School Information Technology Textbook is fully systematically introduced the basic knowledge of the network, which is the main teaching content in the Internet, so in teaching, we should "enable students to obtain, exchange, publicize information on the Internet" as teaching. Target teaching. Due to the restrictions on the region and the economy, some schools have no internet access conditions, and for information technology, interest is the best teacher, so you can't "can't go online", and the contents of this chapter skip. How do we solve this contradiction? Today, we have entered a new information era. The product of this era of network has gradually formed a culture with distinctive age.

How do we solve this contradiction?
The Internet applications in Chapter 4 mainly include three aspects: get information on the Internet, communicate information on the Internet and publish information on the Internet. My teaching is done in the LAN and has achieved better results. Here is my operating example:
Ready to work
To achieve these three teaching goals, first step is to establish a site in your local area network. So how do you live in the LAN? Its key is to get your server, the specific operation is as follows (take the practice of our school's student room as an example):
The server uses Windows NT, requires the installation of web services, DHCP services, DNS services, TCP / IP protocols, and server names NTServer, and set the IP address to 192.168.0.1.
1, configure DHCP service
The DHCP server automatically assigns the IP address for the client, so the first management work is to create a scope of the IP address range, and the setting steps are as follows:
1 Click [Start] → [Program] → [Administrative Tools] → [DHCP Manager] to enter the DHCP Administration Tool.
2 In the "DHCP Server" list of the DHCP Manager window, select the server you want to create a scope to you. Then select the "Add ..." command in the Server menu, and enter the server's IP address, such as 192.168.0.1.
3 Double-click the newly created server, in the Schemes menu, click Create to open the Create Domain dialog. Set the IP address range from 192.168.0.2--192.168.0.250. The next is to add the exclusion and set the lease period, which can use the default value.
4 Activate the DHCP scope and click "Evergreen" in the "Scheme" menu.
2, configure DNS service
The DNS server is used for the conversion between the IP address and the domain name address.
1 Click [Start] → [Program] → [Administrative Tools] → [DNS Manager] to enter the DNS management tool. 2 Select the "New Server" in the "DNS" menu, enter the server name in the dialog, such as 192.168.0.1
3 Right-click New Server and select "New Area ...". Select the area type "Main" in the dialog that appears, click Next. Enter zszxit.com in the domain name, and the remaining items can be skipped by using the TAB key, and the system will automatically give the default name, and finally confirmed.
4 Right-click New Main Large Zszxit.com, select "New Host". In the dialog that appears, enter the host name WWW, the corresponding IP address is 192.168.0.1.
With the above preparation, we can implement Internet teaching in our local area to make the server.
Second, get information on the Internet
(1) In the local area network, there is a home - establish a teaching site
To build a teaching site, you have to configure web services, and configure web services first configure IIS to support web services. IIS (Internet Information Server) is automatically installed with Windows NT installation, but the version is low, it is recommended to upgrade to version 4.0. IIS establishes "default Web Site" in the system, whose home directory is C: / INETPUB / WWWWROOT, the default home page is default.htm, we can make a corresponding setting as needed.
In Windows NT, the IIS publishing the Web site can be implemented in a variety of ways, of course, you must prepare the documentation you want to publish before publishing any site. The easiest way is to copy the web document you want to publish to the main directory C: / INETPUB / WWWWROOT, the home page The default file is named Default.htm. To manage the orderless, we set a folder D: / ITWeb in the D-disk root directory, as the main folder of the website, put the content of the prior design website in this folder, then add the site, the specific operation is as follows :
1 Open Internet Service Manager, right-click the server name, select [Add] → [Web Site] option.
2 Click Next, enter the description text of the new site, such as "IT", then click Next to plan the settings of the user connection, the IP address is set to 192.168.0.1, the TCP port uses the default value 80
3 Click Next, enter your home directory path such as D: / ITWEB, follow-up steps can be used.
At this point, a teaching Web site has been established, and the domain name is entered in any workstation browser address.
Www.zszxit.com, or IP address, you can browse your own site if 192.168.0.1. As long as you link the required information to your own site, you can achieve your information.
(2) Use Serv-U to build its own powerful FTP server
To achieve FTP teaching, you must build your own FTP server. I am implemented by Server-U, the specific operations are as follows:
First install the original software and the Chinese patch, this process does not say much, I will not do it. After the installation is complete, the program will run automatically, you can also choose to run in the menu.
1. First run the program, it will pop up the setup wizard window will take you to complete the original setting;
2. Click Next, "Show Menu Image" window, ask if you display a small image in the menu, see each person likes;
3, click "Next", this window is allowed to run the FTP server in the local place, as long as "Next" is fine; 4, then you want you to enter your IP address, such as 192.168.0.1;
5, click "Next", here you want you to enter your domain name, if you have, such as:
Www.zszxit.com, no words, just fill one;
6, click "Next", ask if you allow anonymous access, generally, anonymous access is logged in with Anonymous, no password, of course, if you want to set up a member area, you should choose "No" Don't let anyone can log in, only license users, we fill in "Yes" here.
7, click "Next", ask your anonymous user log in to your computer, you can specify the existing directory on a hard disk, such as E: / ITFTP;
8, click "Next", ask if you want to lock the directory, after locking, the user who logs in anonymous login will only think that the directory you specify is the root directory, that is, he can only visit this The files and folders in the directory cannot be accessed outside of this directory. For anonymous users, "Yes";
9. Click "Next" to ask if you create a named account, that is, you can specify that the user accesses your FTP with a specific account, which is useful for the member area, you can create an account for everyone. If the permissions of each account are different, you can limit the right of everyone in different programs, and "Yes" here;
10. Click "Next", please fill in the name of the account to be created, such as: Manager;
11. Click "Next", please enter your password, such as: 123;
12, click "Next", ask if the login directory is, this step is in step 7
Like: E: / ITFTP;
13. Click "Next" to ask if you want to lock this directory, step 8, this
Select "NO";
14, next to ask your administrator privileges for the user created, there are several options:
No permissions, group administrators, domain administrators, read-only administrators and system administrators, each item is different; here is "system administrator";
15, the last step, click "Finish" to OK, what do you need to modify,
You can click "Previous" or enter the Serv-U administrator directly to modify. At this point, we have established a domain
Www.zszxit.com, two users, an Anonymous, a manager; after the setting is complete, you will enter the main interface of the Serv-U administrator, as shown in the left pane, display each column in the right pane, display each column The specific option, the following is about to talk about the settings.
1. In the figure, we can manually control the operation or stop of the Serv-U engine;
2, "License", if you bought the registration number, you can input it; 3, "Set", this setting is for "local servers".
4, "Activity", records the user's activity log, the blocked IP activity log, and task log;
5, "Domain", here contains you started based on users, setting, domain, etc. according to the wizard.
Figure SERV-U administrator's main interface
6, "Domain → Group", we can build some of the groups that are easy to manage, and then
A type of user is returned to a group. 7, "Domain → User", you can see the two accounts we create, an Anonymous, a Manager.
With these, we can realize our FTP teaching, establish a directory iTFTP in the E disk, put the file you need to download in, so you can enter in the IE address bar of any workstation.
FTP: //www.zszxit.com can log in anonymously to the local server. Of course, we can also log in to the FTP server in different users. Open Server-U, in the field
Create user student, enter your password, enter your password, select the directory access tab, select Add, the access is set to read, write and allow you to create a directory, write and allow you to create a directory, write and allow you to create a directory. Allow deletion so you can log in to your FTP server as a STUDENT, and implement the upload of the file.

(3) Do the search engine in your own station with COOL Search Maker
The search engine is used up to one tool, which can be roughly divided into two, one is the popular search engine site, such as Sohu, Yahoo, Google, etc., the other is the search engine in the site. Sometimes users browse your website is just to get a small part of the information and don't want to browse your hopes. If you have a "station search engine", you will have a great convenience. Here is the "Site Search Engine" production tool Cool Search Maker.
Software installation
This step is relatively simple, I believe no one will not.
Produce local search engine files
(1) Add local site
Click Folder to select the folder where your local site is located, as shown
At this time, the COOL Search Maker automatically reads information about all files under this folder. (2) Generating Search Engine Scripts Click "Build", the software automatically generates the search.html file, the default generating path is "Output" of the software installation directory. (3) Test Click "Run", the software will automatically open the web search.html, this test page is very simple, only one input field and a Search button. You can use the text on your website in your website for testing, and the software will automatically generate a very similar result page that is very similar to Google. Add a search engine to your website to copy Search.html to your site's root of your site, add a "Site search" hyperlink in your home page. At this point, the search engine in your station is all completed. Third, exchange information on the Internet (1) Easy to get E-mail now almost all the websites have an email application, so how do I implement E-mail in my own LAN? Here you introduce a very good tool, that is, Webeasymail. 1. Installation and configuration (1) Install WebeEasymail to a directory (such as: d: / itWeb); (2) Open "Internet Service Manager"; (3) Add Virtual Directory under "ITWeb" Webeasymail ", The virtual directory actually points to the web directory under WebEasymail (such as: D: / itWeb / WebEasymail / Web); (4) Start file as default.asp (Note: Global.asa file must be in this" virtual directory ") 2, the domain name setting (1) Domain name setting is the domain name after setting the user email address "@" number, the system default domain name: system.mail, when adding a new user, such as the user name: ABC, The user's default email address on the Web Easy Mail mail server is: abc@system.mail (2) Open "WebeEasymail" in "Start" → "Programs" → "WebeEasymail", and "domain management "Add a new domain name (such as zszxit.com). This allows users to use new email addresses (such as: abc@zszxit.com). 3, set the hyperlink in the home page to set the hyperlink named "Mail Center" in the homepage of your site, this is WebEasymail, so you can apply for an email and use mailbox by opening the Mail Center option in the home page. . When you apply for multiple accounts, you have to open each mailbox if you want to send and receive emails, which is more trouble, then you can send up your own email through Outlook Express. Of course, a little should also tell the student's IP address (192.168.0.1) of the WebEasymail server so that they can be set accordingly in email transceivers such as Outlook. (2) QQ in the local area is also crazy now, there is almost no one knows QQ. Students are no exception. They naturally have very curious about QQ this chat tool. So since we can't access the Internet, naturally You can't use QQ, but this doesn't matter, we can achieve it through other software.
That is freeicq, this is a great local area page! It is a set of instant messaging software mainly for local area networks, including server and client. It uses a similar OICQ interface, easy to operate, and the computer has a low configuration requirement, easy to install, you can quickly create an instant messaging system quickly. You just need to install its server-side software FRESERVER on the server, you can install the client's software FICQ. Of course, you can control through the server's software, you can use it if the server is started. Try it quickly, very good! (3) You talk about me to talk about E-mail, QQ, you can also build a chat room. (1) Copy the file to a directory of the server (such as: d: / itWeb / liaotian); (2) Open "Internet Service Manager"; (3) Add a virtual directory "liaotian" under "ITWeb", The virtual directory actually points to the folder of the store file (such as D: / ITWEB / LIAOTIAN) (4) Set the "chat room" in the homepage of your site, the link address is "liaotian" so you can open it. The "chat room" in the home page is chatted online. (4) The BBSBBS in the LAN is also an indispensable flawless landscape in information exchange, I use FreeBBS to implement the Forum in the LAN. Software installation (1) Unzip the zip file into a directory (such as E: / ITWEB / BBS), create a virtual directory (such as / bbs) with read and script attributes in the IIS Administration program (2 ) Move the bbs.mdb to another directory, and create a virtual directory that cannot be read or Write (such as / bbs / data) (such as / bbs / data) (such as / bbs / data) (such as / bbs / data) (such as / bbs / data) (such as / bbs / data) (such as / BBS / DATA). The last line is: conn.open "driver = {Microsoft Access Driver (* .mdb)}; dbq =" & Server.mappath ("/ bbs") & "/bbs.mdb;" Sections in Mappath () , Replace the web path where you have just created database files. For example, the web path installed on your machine is http://www.yousite.com/yourname/bbs/.s the virtual directory established for the database http://www.yoursite.com/yourname/bbs/data/ Then, "/ BBS" is replaced 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) Finally, you add a "online forum" super link on your home page, the link address is BBS, so you can use Freebbs .
