Remarks

This method is called only if you implemented IwodSSHNotify interface in your application, and wodSSHD.Notification property has received reference to instance of your implementation.

This notification method is called when connected user requests service from wodSSHD to open specified port (BindPort value) for listening. If you set Action to Allow, wodSSHD will open this port and listen for incoming connections, if possible. When connection arrives, notification method PortForwardConnect will be called where you can see the Hostname of user who's trying to use this opened port. If all is Allowed, remote client will receive message about this connection, and it will be able to receive forwarded data for this connection.

Bind requests are typically used to protect plain communication from 3rd party sniffing (eavesdropping). For example, instead of opening local port on his computer, client can request server to open port. Complete traffic between wodSSHD server and the client will be encrypted (it's traveling through already established SSH connection).

If wodSSHD should initiate outgoing connection, notification method PortForwardRequest will be called.
