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 <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
