Class ListenFailedAlert

java.lang.Object

com.frostwire.jlibtorrent.alerts.AbstractAlert<listen_failed_alert>

com.frostwire.jlibtorrent.alerts.ListenFailedAlert

All Implemented Interfaces:

Alert<listen_failed_alert>

public final class ListenFailedAlert
extends AbstractAlert<listen_failed_alert>

This alert is generated when none of the ports, given in the port range, to session can be opened for listening. The listenInterface() member is the interface and port that failed, error() is the error code describing the failure.

In the case an endpoint was created before generating the alert, it is represented by ``address`` and ``port``. The combinations of socket type and operation in which such address and port are not valid are: accept - i2p accept - socks5 enum_if - tcp

libtorrent may sometimes try to listen on port 0, if all other ports failed. Port 0 asks the operating system to pick a port that's free). If that fails you may see a ListenFailedAlert with port 0 even if you didn't ask to listen on it.
