NcFTPd general.cf file configuration
Don't forget to restart NcFTPd after modifying the general.cf file.
This allows you to control how long the server should wait when it waits for a passive FTP data connection to be established from the remote client, or how long it waits when it tries to connect to the remote client for an active FTP data connection.
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), the control connection idle timeout (idle-timeout), and the login timeout (login-timeout).
