idle-timeout
The FTP control connection serves as a conversation where the remote client
issues commands to the server. This controls how long to wait after
a command has completed before hanging up on an idle FTP client.
The value is specified in seconds, and must be greater than zero.
Other timeout values you can configure are the data transfer block timeout
(xfer-timeout) and the connection establishment
timeout (conn-timeout).
Examples:
idle-timeout=300
idle-timeout=900
