FTP Client Output Response standard

After successful FTP file transfer, the the response is used to be "226 File send OK", but suddenly, it has changed to be "226 Transfer complete"

I have below questions:

  1. Does FTP response code has any standard?
  2. Can we customize FTP output response for a specific status code?

Find the standard FTP response for file transfer

Solution

  • RFC 959, 4.2. FTP REPLIES:

    An FTP reply consists of a three digit number (transmitted as three alphanumeric characters) followed by some text. The number is intended for use by automata to determine what state to enter next; the text is intended for the human user. It is intended that the three digits contain enough encoded information that the user-process (the User-PI) will not need to examine the text and may either discard it or pass it on to the user, as appropriate. In particular, the text may be server-dependent, so there are likely to be varying texts for each reply code.
