Of course, you can't use more than one such machine per broadcast domain. You can also use locally-administered MAC addresses; I have a Sun whose NVRAM-stored MAC address is 02:ff:8e:40:7c:f9 (the 02 bit in the first octet indicates "locally administered MAC space", the ff is a disambiguator because I use mechanically-generated 02:00: MACs for other purposes, and the other four octets came straight from /dev/random; I could have used fe: plus five random octets, but didn't feel the need to bother). I did this because the machine came to me with a flat battery and no indication of what its MAC used to be. That appears to have been a mistake on the part of the person who wrote it. My saved copies came from squirrel.com (not .org), text at http://www.squirrel.com/squirrel/sun-nvram-hostid.faq with an HTMLized version at http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html both of which were live when I checked while writing this mail. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
