Other computers on the network can copy, move, create, or delete files and directories by connecting to the FTP server.
10.3.1 install Serv-u and set up an FTP server
After downloading the serv-u application, execute the ServU4004.exe and install it step-by-step as prompted. After the installation is complete, you do not need to restart the computer, the user can directly select the "start" → "program" → "serv-u FTP Server" → "serv-u Administrator" command to start the application, and simple settings. Below we take the current computer (IP address is 192.168.0.1, domain name server.kangbo.com) as an example, the establishment of an FTP server.
The steps to establish an FTP server are as follows:
(1) Start the Serv-u program and open the Serv-u Administrator window, which displays the Setup Wizard dialog box, as shown in Figure 10-13. Use this dialog box to easily complete the basic settings.

(7) Click the Next button to open the lock in Home Directory dialog box and select the Yes radio button to lock the anonymous access directory. In this way, users who log on anonymously will only have access to files and folders in the home directory, and other files and folders outside this directory will not be accessible.
(8) Click the Next button, open the Named Account dialog box, select the Yes radio button, create the named accounts, so that users can access FTP with a specific account.

10.3.3 Create a virtual directory
For an anonymous user (Anonymous), his home directory is C:\MyFTP, and if you want to access the content in C:\Wang through ftp://192.168.0.1/temp format, you need to add a virtual directory to it.
The steps to establish a virtual directory are as follows:
(1) In the Serv-u Administrator window, click the Settings node under the server node and select the General tab.
(2) Click the Add button to open the virtual Path Mappings-step 1 dialog box and enter the physical path, such as C:\MyFTP, in the Physical Path text box.
(3) Click the Next button to open the virtual Path Mappings-step 2 dialog box and enter the directory name, such as C:\Wang, that the path is mapped to in the map physical path to text box.
(4) Click the Next button to open the virtual Path Mappings-step 3 dialog box, and in the Map path name text box, enter the name of the dummy directory, such as temp.
(5) Click the Finish button to complete the virtual directory creation, and the results are shown in Figure 10-16.
Figure 10-16 Creating a virtual directory
(6) Select the anonymous user in the left pane of the organizer, and then switch to the Dir Access tab in the right pane, and then click the Add button to add the C:\Wang directory to the list.
When using the Serv-u administrator to create a server site, we have created a anonymous user and a Wang user. Administrators can also add, delete, copy, or disable users as needed.
To add a new user, including adding anonymous users, you can right-click the users node in the left pane of the Administrator window. Pop-up shortcut menu, select New User command, open the Add New User dialog box. Follow the prompts and enter the username (user name), password (Password), and home directory in turn.
To remove a user, right-click the selected user and select the Delete User command from the pop-up shortcut menu.
To copy a user, you can right-click the selected user and select the Copy User command from the pop-up shortcut menu, and a new user is generated (whose name is add copy of before the original user name). In addition to the user name and the original user, the other items (including passwords, home directories, directory permissions, etc.) are exactly the same.
To temporarily disable a user's logon rights, select the user, and then switch to the Account tab and enable the Disable Account check box. 10.3.5 Manage Directory Permissions
Select the user name in the left pane of the Serv-u Administrator window, and then switch the right pane to the Dir Access tab. Once you have selected the table of contents in the list, you can change the access rights of the current user on the right side of the window, as shown in Figure 10-17.
Figure 10-17 Setting access permissions
Access rights are divided into 3 categories, namely file, directory, and subdirectory permissions. Where file permissions include Read,write,append,delete and execute; directory permissions include list,create and remove; subdirectory permissions are only inherit. When the corresponding check box is enabled, the permissions that are set will work on the current directory and the entire tree under it.
10.3.6 Client Connections
On the client side, users can connect to the configured FTP server in a variety of ways, such as DOS, IE, or dedicated FTP client applications.
In a DOS (or command prompt) state, the client's access format is ftp-a 192.168.0.1, logged on anonymously, without entering a username and password.
In IE browser, the client's access format is ftp://192.168.0.1, and no user name or password is required.
In the dedicated FTP client application settings, such as CuteFTP version 4.2, in Chinese, as shown in Figure 10-18, enter the site label name (arbitrary) in the Site label text box, and in the host address Enter the FTP server site address 192.168.0.1 in the text box, and enter the user name and password, respectively, in the user ID and Password text boxes. Then click the OK button.
In the client connection, the IP address 192.168.0.1 can also be replaced with the computer name server.kangbo.com. In DOS, other characters are case-insensitive except for a in Ftp-a 192.168.0.1, which must be capitalized. If you are logged in using the FTP 192.168.0.1 format in DOS mode, you will need to enter the username and password for the login.
