6.5.4. idle_connection_timeout¶
- Default value:
300
- Optional:
Yes
- From version:
3.0.0
- Values:
Number of seconds
0
- Description:
This controls the automatic disconnection from the remote server after the location has not received any file transfer operation requests for the configured number of seconds.
Keep-alive command requests are not counted as file transfer operations. The connection gets automatically disconnected if keep-alive is the only command requested in the configured interval.
Disconnected locations automatically reconnect when a new file transfer operation request is made. For example, when a new file needs to be transferred to the remote server.
If the remote peer closes the connection before the configured timeout, the connection is left closed. It gets automatically reconnected when a new file transfer operation is requested.
Set to 0 to always keep the connection active, by forcing re-connection when the remote server closes the connection.
Note
The idle_connection_timeout is the maximum number of seconds before closing an idle connection to the server. If the remote server decides that the connection is idle and closes the connection, SFTPPlus doesn't try to "challenge" the server, leaving the connection closed. The connection is automatically reopened next time a file needs to be transferred.
