Ftp configuration diagram

FTP is an abbreviation of File Transfer Protocol, which is used to transfer files between two computers. As one of the oldest services on the Internet, FTP service has an irreplaceable role in the past and the present. In the enterprise, the sharing of some large files is usually done in the form of FTP, and because FTP can eliminate the differences between operating systems, the role of sharing files between different operating systems is particularly prominent.

First, the working mode of the FTP server

The FTP protocol has two working modes: PORT mode and PASV mode. Chinese means active and passive. The PORT (active) connection process is: the client sends a connection request to the server's FTP port (the default is 21), the server accepts the connection, and establishes a command link. When data needs to be transmitted, the server sends a connection request from port 20 to the client's idle port, establishing a data link to transmit data. The PASV (passive) connection process is: the client sends a connection request to the server's FTP port (the default is 21), the server accepts the connection, and establishes a command link. When data needs to be transferred, the client sends a connection request to the server's free port to establish a data link to transmit data.

The FTP server can log in in two ways, one is anonymous login, and the other is to log in with an authorized account and password. Among them, the general anonymous login can only download the files of the FTP server, and the transmission speed is relatively slow. Of course, this needs to be set on the FTP server. For such users, FTP needs to be restricted, and it is not appropriate to open excessive permissions. The bandwidth is also as small as possible. Instead of requiring an authorized account and password to log in, he needs the administrator to tell the user the account number and password. The administrator sets these accounts, such as which resources they can access, download and upload speed, etc., and the administrator needs to perform such accounts. Limit, and reduce the permissions as much as possible. If it is not necessary, you must not give the account administrator rights.

Second, use WINDOWS component IIS to build FTP server

When setting up FTP website, there is no other special requirement for this service as a shared file, you can use Windows XP/2000/The IIS component of the 2003 operating system is completed. Let's take a brief explanation:

1. IIS installation, you can follow the "Start" “——>“Set”——>“Control Panel”— —>“Add/Remove Programs", open the “Add/Remove Programs“ dialog box, select “Add/Remove Windows Components” appears as shown below

2. Follow the diagram below The display continues,

This completes the FTP installation configuration.
