server and then sends commands to the server. The server returns a response after receiving the command and executes the command. The FTP protocol has nothing to do with the operating system. Any program on the operating system can transmit data to each other as long as it complies with the FTP protocol. Based on the Linux platform, this article gives a detailed
process. Sometimes, the crash of computers on either side of the network or network problems can cause the entire transmission to break before it is complete.
If the client is not responding for more than 15 minutes (900 seconds), the FTP connection times out and interrupts.
at the bottom, FTP uses TCP only, not UDP.
In addition,

, users often encounter two concepts: "Download" (Download) and "Upload" (Upload). A "Download" file is a copy of a file from a remote host to its own computer; the "upload" file is a copy of the file from your computer to a remote host. In the Internet language, users can upload (download) files to (from) a remote host through a client program.Operating mechanismFTP ServerSimply put, a server that supports the FT
