How to configure Linux ftp server and client

What is FTP?

FTP, the File Transfer Protocol, is one of the original network applications developed with the TCP/IP protocol suite. It follows the standard model for network services, as FTP requires a server and client  ,  FTP is to solve the need to publish documents and software so that people could get them easily from other computer systems on the network. On the FTP server, files were organized in a directory structure; users could connect to the server over the network ,and download and uploads files from the server.

FTP uses TCP ports 20 (for ftp data) & 21 (ftp program).
