In which case, there's no way that you can obtain its MAC address. BTW, pinging won't help in any case. If the client *does* happen to be on the same network as the server, the MAC address will have been retrieved in order to send the SYN+ACK. -- Glynn Clements <glynn.clements@virgin.net> - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
