| - | **GO NAWAZ GO** | + | ====== FTP Server Return Codes ====== |
| + | FTP server return codes are numerical codes that FTP server uses to indicate result of client request (i.e. request sent by WinSCP to the server). | ||
| + | |||
| + | The return codes always have three digits. The first digit denotes whether the response is good, bad or incomplete. The second digit designates type of error. The third digit distinguishes specific error. For more details refer to | ||
| + | |||
| + | ===== First Digit ===== | ||
| + | ^ Range ^ Meaning ^ Description ^ | ||
| + | | ''1yz'' | Positive Preliminary reply | The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process sending another command before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP process may send at most, one ''1yz'' reply per command. | | ||
| + | | ''2yz'' | Positive Completion reply | The requested action has been successfully completed. A new request may be initiated. | | ||
| + | | ''3yz'' | Positive Intermediate reply | The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in command sequence groups. | | ||
| + | | ''4yz'' | Transient Negative Completion reply | The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. The intent is that the user-process is encouraged to try again. | | ||
| + | | ''5yz'' | Permanent Negative Completion reply | The command was not accepted and the requested action did not take place. The User-process is discouraged from repeating the exact request (in the same sequence). | | ||
| + | |||
| + | ===== Second Digit ===== | ||
| + | ^ Range ^ Meaning ^ Description ^ | ||
| + | | ''x0z'' | Syntax | These replies refer to syntax errors, syntactically correct commands that don't fit any functional category, unimplemented or superfluous commands. | | ||
| + | | ''x1z'' | Information | These are replies to requests for information, such as status or help. | | ||
| + | | ''x2z'' | Connections | Replies referring to the control and data connections. | | ||
| + | | ''x3z'' | Authentication and accounting | Replies for the login process and accounting procedures. | | ||
| + | | ''x4z'' | Unspecified as yet. | | | ||
| + | | ''x5z'' | File system | These replies indicate the status of the Server file system vis-a-vis the requested transfer or other file system action. | | ||
