LIST OF COMMON FTP ERROR CODES
File Transfer Protocol (FTP) is a network protocol responsible for transferring file between hosts. An FTP on the other hand, is a server that serves as a central repository for files that users can download and, in some cases, upload.
It can then also authenticate users based on user name and password combination but and FTP server can also be configured to allow users to connect anonymously.
FTP uses TCP/IP port 20 and 21; port 20 is for transmitting data between the FTP server and client while the port 21 is used for transmitting instructions between the FTP server and client.
FTP server return codes always have three digits and each digit has a unique meaning. The first digit denotes whether the response is good, bad or incomplete.
