Hi gang, this one comes from MacOSX-Hints: % sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff where en0 is the network interface (numbered from en0, en1, en2 ...) and aa:bb:cc:dd:ee:ff is the desired MAC address in hex notation. But, it should be called before the network is initialised. How do I do this? -- Greetings, [4D-Consulting.com]eK, Wiesbaden Peter Schumacher -------------------------------------------------------- Web: http://www.4D-Consulting.com/ AIM/iChat: PeterInWiesbaden 0800-4D-Infos / 0800-43.46.367 - Fax: 0800-43.46.637 Intl +49-611-9406.850 - Intl: +49-611-9406.744
