This article provides information on 553 FTP response code.

Serv-U Managed File Transfer & Serv-U FTP Server

A 553 response code may be given in response to any command requiring or supporting the use of a file name as a parameter. It is a permanent negative reply, which means the client is discouraged from sending the command again since the server will respond with the same reply code. It is usually due to the file name contained as a parameter violating the file naming policies existing on the server. Issuing the command again with a different file name may result in a different reply code.

Example response 

553 Requested action not taken; File name not allowed.

Possible commands 

• APPE FTP command
• RNTO FTP command
• STOR FTP command
• STOU FTP command
