Hi. I am trying to implement my own AbstractServerSocketAppender base ServerSocketappender. For configuring some options on the created ServerSocket I want to override the method AbstractServerSocketAppender.ServerListener<RemoteReceiverClient> createServerListener(ServerSocket socket) Unfortunately this is impossible because the method signature references ch.qos.logback.core.net.server.RemoteReceiverClient which is a non-public interface. Is there any specific reason why this interface is non-public? There are also some other non-public classes and interfaces in this package. If there is not good reason for keeping them private I would recommend to make them all public. Jan
