NOOP FTP command

Updated May 3, 2017


This article describes the use of the No Operation (NOOP) FTP command.


All Serv-U versions


The NOOP command does not cause the server to perform any action beyond acknowledging the receipt of the command. This command can be issued to the server to prevent the client from being automatically disconnected for being idle. It can also prevent modern routers/firewalls from closing a connection that it perceives as being idle as well.
