Method Details

bind

public RemotePortForwarder.Forward bind(RemotePortForwarder.Forward forward,
 ConnectListener listener)
                                 throws ConnectionException,
TransportException

Request forwarding from the remote host on the specified RemotePortForwarder.Forward. Forwarded connections will be handled by supplied listener.

If forward specifies as 0, the returned forward will have the correct port number as informed by remote host.

Parameters:

forward - the RemotePortForwarder.Forward to put in place on remote host

listener - the listener which will next forwarded connection

Returns:

the RemotePortForwarder.Forward which was put into place on the remote host

Throws:

ConnectionException - if there is an error requesting the forwarding

TransportException

cancel

public void cancel(RemotePortForwarder.Forward forward)
            throws ConnectionException,
TransportException

Request cancellation of some forwarding.

Parameters:

forward - the forward which is being cancelled

Throws:

ConnectionException - if there is an error with the cancellation request

TransportException

req

protected SSHPacket req(String reqName,
 RemotePortForwarder.Forward forward)
                 throws ConnectionException,
TransportException

Throws:

ConnectionException

TransportException

getActiveForwards

public Set<RemotePortForwarder.Forward> getActiveForwards()

Returns:

the active forwards.

handleOpen

public void handleOpen(SSHPacket buf)
                throws ConnectionException,
TransportException

Internal API. Creates a RemotePortForwarder.ForwardedTCPIPChannel from the CHANNEL_OPEN request and calls associated ConnectListener for that forward in a separate thread.

Parameters:

buf - SSHPacket containing the request except for the message identifier and channel type field

Throws:

ConnectionException

TransportException
