Let me try with shorter sentences, if you still do not get it maybe I can try a puppets show. Root configures daemon on IPv4-only system. Daemon can only bind to 0.0.0.0. Configuration works. IPv6 is enabled. Daemon now can bind to ::. Daemon accepts IPv4 connection on the IPv6 socket. Configuration broken. -- ciao, Marco
