It seems you are expecting too much of SO_BROADCAST option. http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_10.html SO_BROADCAST : Non-zero requests permission to transmit broadcast datagrams (SOCK_DGRAM sockets only). Note this only handles the transmission of packets, not receiving them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" 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.tux.org/lkml/
