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

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

tearingDownExplicitTunnel

default void tearingDownExplicitTunnel(Session session,
                                       SshdSocketAddress address,
                                       boolean localForwarding,
                                       SshdSocketAddress remoteAddress)
                                throws IOException

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

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

Throws:

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

tornDownExplicitTunnel

default void tornDownExplicitTunnel(Session session,
                                    SshdSocketAddress address,
