On my Mac and on my Linux workstations it simply doesn't work. Using '/usr/sbin/ifconfig' as the executable name in Popen does work, however. The OP didn't state his platform, so we shouldn't assume that a windows-only solution will work for him may. Since this list covers the use of many kinds of operating systems, it is foolish to make assumptions. This was my point.

As Dan has indicated, you have to Popen an external command to get this information. Every OS has different commands and syntaxes for this. You'll have to have a different Popen for each operating system. Also you must take into account that most computers have more than one ethernet interface these days (real and virtual). So you'll likely end up with between 2 and 5 different MAC addresses. And some of those are fake as well, like the MAC addresses used by VMware's virtual networking interfaces. What operating system are you targeting? Windows? Linux? Mac? To really answer your question you must supply more information.

The documentation says: """ getnode( ) Get the hardware address as a 48-bit positive integer. The first time this runs, it may launch a separate program, which could be quite slow. If all attempts to obtain the hardware address fail, we choose a random 48-bit number with its eighth bit set to 1 as recommended in RFC 4122. "Hardware address" means the MAC address of a network interface, and on a machine with multiple network interfaces the MAC address of any one of them may be returned. """ So the return value isn't *guaranteed* to be an ethernet address, and I'm not sure whether that code gets any regular testing. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 See PyCon Talks from Atlanta 2010 http://pycon.blip.tv/ Holden Web LLC http://www.holdenweb.com/ UPCOMING EVENTS: http://holdenweb.eventbrite.com/

I don't know if it works for all platforms. I wrote this a long time ago. I think it would now be preferable to use subprocess() instead of os.popen(). Note the commented-out line in the linux block. This is an alternative method I cribbed from somewhere. Not as readable, but probably faster. HTH Frank Millman
