I'm only half-remembering this, but isn't there a manufacturer range reserved for "user-defined" MAC addresses? If I recall VMWare uses this. Also, will these MAC's be consistent? Normally, were I to use DHCP in this environment, I'd want to be able to always assign machine "foo" the same IP address, the easiest route is 'foo' always has the same MAC. Also, is the MAC generation routine smart enough to not make two of the same on one glan? (I assume yes). >From discussion with a friend: "Now, see, if that was MS, they'd change all networks so they can always route to a central MS server from which it'd check a database for a MAC not in use." :) -m -- Michael Kershaw [EMAIL PROTECTED] Linux Systems Programmer, Information Technology "Don't worry, I'm sure they'll listen to Reason." -- Fisheye, Snowcrash
