Hello Family!!!

Heres a list of codes for FTP servers.

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.
125:--> Data connection already open; transfer starting.
150:--> File status okay; about to open data connection.
200:--> Command okay.
202:--> Command not implemented, superfluous at this site.
211:--> System status, or system help reply.
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.
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.
221:--> Service closing control connection. Logged out if appropriate.
