ftp (error, status) code

Code	Status or Error Description, 상태 혹은 에러 설명
	100 Series - Positive Preliminary Reply (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.
110	Restart marker reply. In this case, the text is exact and not left to the particular implementation; it must read: MARK yyyy = mmmm Where yyyy is User-process data stream marker, and mmmm server’s equivalent marker (note the spaces between markers and "=").
120	Service ready in nnn minutes. nnn분안에 서비스가 준비됩니다.
125	Data Connection already open, transfer starting. 데이타 전송연결이 이미 열려있습니다, 전송을 시작합니다.
150	File status okay, about to open data connection.  파일이 이상이 없고 데이타 연결을 시작합니다.
	Description
	200 Series - Positive Completion reply  The requested action has been successfully completed. A new request may be initiated.
200	Command okay.
202	Command not implemented, superfluous at this site. 이사이트에 불필요한 명령으로 구현되지 않았습니다.(지원하지 않습니다)
211	System status, or system help reply. 시스템 상태 또는 시스템 응답
212	Directory status.
213	File status.
214	Help message.  On how to use the server or the meaning of a particular non-standard command. This reply is useful only to the human user. 서버 사용방법 또는 특정 비표준 명령의 대응, 사용자에게 유용합니다.
215	NAME system type. (Where NAME is an official system name from the list in the Assigned Numbers document.)
220	Service ready for new user. 새로운 유저를 위한 서비스 준비가 되었습니다.
221	Service closing control connection. Logged out if appropriate. 적절한 로그아웃을 했다면 연결을 종료합니다.
225	Data connection open; no transfer in progress. 데이타 연결이 열렸습니다. 파일전송이 진행중이지 않습니다.
226	Closing data connection. Requested file action successful (for example; file transfer or file abort). 데이타 연결을 종료합니다. 요청된 파일 명령이 성공적입니다.(파일 전송 또는 취소)
227	Entering Passive Mode.
230	User logged in, proceed.
250	Requested file action okay, completed.
257	"PATHNAME" created.
	300 Series - 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
331	User name okay, need password.
332	Need account for login.
350	Requested file action pending further information.
	400 Series - 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. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4yz category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4yz or the 5yz (Permanent Negative) category is that replies are 4yz if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.)
421	Service not available, closing control connection. This may be a reply to any command if the service knows it must shut down.  This error may be due to service not available, closing control connection, user limit reached, or you are not authorized to make the connection, or the maximum number of connections have been exceeded. 서비스가 가능하지 않습니다. 콘트롤 연결을 종료합니다. 종료해야하는 어떤 명령에 따른 응답. 유저접속 제한에 걸렸거나 인증받지 않은 연결 시도, 최대 연결 횟수제한에 걸렸을때 발생
425	Can’t open data connection.  데이타 연결을 열수 없습니다.(list를 받지 못하거나 하는 상태도 마찬가지)
426	Connection closed; transfer aborted.  The command opens a data connection to perform an action, but that action is canceled, and the data connection is closed. 연결 종료. 전송 취소됨. 명령이 작동중 취소되었을때 발생하고 데이타 연결은 종료됨.
450	Requested file action not taken. File unavailable (e.g., file busy).
451	Requested action aborted: local error in processing.
452	Requested action not taken. Insufficient storage space in system.
	500 Series - 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). Even some "permanent" error conditions can be corrected, so the human user may want to direct his User-process to reinitiate the command sequence by direct action at some point in the future (e.g., after the spelling has been changed, or the user has altered his directory status.)
501	Syntax error in parameters or arguments.  This may include errors such as command line too long. 옵션 구문에러. 명령라인이 너무김같은 에러를 포함.
502	Command not implemented. The server does not support this command. 명령이 실행되지 않았습니다. 서버가 해당 명령을 지원하지 않습니다.
503	Bad sequence of commands. 명령 순서가 잘못되었습니다.
504	Command not implemented for that parameter.
530	Not logged in.   login incorrect.
532	Need account for storing files.
550	Requested action not taken. File unavailable (e.g., file not found, no access). 요청한 동작을 할수 없음.  (파일 없음, 읽을수 없음)
552	Requested file action aborted. Exceeded storage allocation (for current directory or dataset).
553	Requested action not taken. File name not allowed.
