Method Details

establishedExplicitTunnel

public void establishedExplicitTunnel(Session session,
 SshdSocketAddress local,
 SshdSocketAddress remote,
 boolean localForwarding,
 SshdSocketAddress boundAddress,
 Throwable reason)
                               throws IOException

Description copied from interface: PortForwardingEventListener

Signals a successful/failed attempt to establish a local/remote port forwarding

Specified by:

establishedExplicitTunnel in interface PortForwardingEventListener

Parameters:

session - The Session through which the attempt was made

local - The local address - may be null on the receiver side

remote - The remote address - may be null on the receiver side

localForwarding - Local/remote port forwarding indicator

boundAddress - The bound address - non-null if successful

reason - Reason for failure - null if successful

Throws:

IOException - If failed to handle the event - in which case the established tunnel is aborted

tornDownExplicitTunnel

public void tornDownExplicitTunnel(Session session,
 SshdSocketAddress address,
 boolean localForwarding,
 SshdSocketAddress remoteAddress,
 Throwable reason)
                            throws IOException

Description copied from interface: PortForwardingEventListener

Signals a successful/failed request to tear down a local/remote port forwarding

Specified by:

tornDownExplicitTunnel in interface PortForwardingEventListener

Parameters:

session - The Session through which the request is made

address - The (bound) address - local/remote according to the forwarding type

localForwarding - Local/remote port forwarding indicator

remoteAddress - The specified peer address when tunnel was established - may be null for server-side local tunneling requests

reason - Reason for failure - null if successful

Throws:

IOException - If failed to handle the event - Note: the exception is propagated, but the port forwarding may have been torn down - no rollback

establishedDynamicTunnel

public void establishedDynamicTunnel(Session session,
 SshdSocketAddress local,
 SshdSocketAddress boundAddress,
 Throwable reason)
                              throws IOException

Description copied from interface: PortForwardingEventListener

Signals a successful/failed attempt to establish a dynamic port forwarding

Specified by:

establishedDynamicTunnel in interface PortForwardingEventListener

Parameters:

session - The Session through which the attempt is made

local - The local address

boundAddress - The bound address - non-null if successful

reason - Reason for failure - null if successful

Throws:

IOException - If failed to handle the event - in which case the established tunnel is aborted

tornDownDynamicTunnel

public void tornDownDynamicTunnel(Session session,
 SshdSocketAddress address,
 Throwable reason)
                           throws IOException

Description copied from interface: PortForwardingEventListener

Signals a successful/failed request to tear down a dynamic port forwarding

Specified by:

tornDownDynamicTunnel in interface PortForwardingEventListener

Parameters:

session - The Session through which the request is made

address - The (bound) address - local/remote according to the forwarding type

reason - Reason for failure - null if successful

Throws:
