Status messages from the File Transfer Protocol server
When you enter subcommands during a File Transfer Protocol (FTP) client session, status messages return to your display in a 3-digit code: xyz. Each digit has certain values that indicate a different status.
The first digit (x) tells you whether the response is good, bad, or incomplete. There are five values for the first digit:
- 1yz = Good. The requested action is being initiated; another reply should follow.
- 2yz = Good. The requested action was successfully completed; a new request may be initiated.
- 3yz = Incomplete. The subcommand was accepted, but the requested action is being held pending receipt of more information.
- 4yz = Incomplete. The FTP server did not accept the subcommand. The requested action did not take place. The error is temporary and you can request the action again.
- 5yz = Bad. The subcommand was not accepted, and the requested action did not take place.
The second digit (y) tells you the functional category of the response.
- x0z=Syntax. Refers to syntax errors, commands that aren't appropriate for what you're trying to do, and unnecessary commands.
- x1z=Information. Refers to requests for information, such as status or help.
- x2z=Connections. Refers to the control or data connections.
- x3z=Authentication. Refers to the login process.
- x5z=File system. Refers to the status of the FTP server in relation to the file transfer request.
The third digit (z) tells you a finer level of detail about the functional category.
