1. FTP
File Transfer Protocol (FTP) is a set of standard protocols for file transfer on the network. It works on the seventh layer of the OSI model and the fourth layer of the TCP model, that is, the application layer, using TCP transmission.
The FTP protocol is divided into two parts: one part is used to transmit control commands, and the other part is used to transmit data, such as the current directory or the file to be transferred.
FTP allows users to communicate with another host through file operations (such as adding, deleting, modifying, checking, transferring files, etc.). However, users do not actually log in to the computer they want to access and become a full user. They can use FTP programs to access remote resources, allowing users to transfer files back and forth, manage directories, access emails, etc.
2. The role and goals of FTP
1. The goal of FTP is
to improve file sharing and transfer data reliably and efficiently.
When transferring files, the FTP client first establishes a connection with the server and then sends commands to the server. The server responds after receiving the command and executes the command.
The FTP protocol has nothing to do with the operating system. Programs on any operating system can transfer data to each other as long as they comply with the FTP protocol.
3. What are the commonly used FTP server programs?
1. FTP service
FTP server is an optional role service in the "Web Server" (IIS) role of Windows Server 2016. IIS is the abbreviation of Internet Information Services. It is a basic Windows-based Internet service provided by Microsoft, including the most commonly used WWW, FTP and E-mail services, available for Intranet, Internet or Extranet.
2、Serv-U
Serv-U is currently the most widely used FTP server program, supporting a full range of Windows versions. Using Serv-U, any personal computer can be set up as an FTP server, regardless of the Windows version used.
3. Other FTP server programs
Other FTP server software includes Xlight ftp Server, RaidenFTPD, EFT Server, etc., and there are also free and open source software.
4. The role of Serv-U
Serv-U FTP Server is a widely used FTP server software that supports all Windows series such as 3x/9x/ME/NT/2K. You can set multiple FTP servers, limit the permissions of logged-in users, log in to the home directory and space size, etc. The functions are very complete. It has very complete security features, supports SSL FTP transmission, and supports protecting your data security through SSL encrypted connections on multiple Serv-U and FTP clients.
