get mac address...
|
|
| SpreadTooThin 2007-06-08, 7:20 pm |
| On Mac OS X, in C++
I want to get the hardware mac address of the machine... (First device
if more than one.)
I've seen example that do a pipe ifcongif and grep for the mac
address... but surely there is a direct api to get the mac address.
TIA

What does it mean for a particular device to be "first" ?
If I have a built in ethernet, and a built in wireless and
a firewall connection and a series of USB devices some of which happen
to have MACs, then which is the -first-? Especially when it comes
to the USB devices: they are likely to be on a different list
than the built-in ethernet varieties, so "first" would depend on
where you looked first.
Does it matter for your purpose whether the "first" mac is associated
with a device which is active? (If not, then you're probably trying to
use the Mac as a machine serial number, which has various associated
problems.) Does it matter for your purpose whether the "first" mac
is associated with a removable (and likely to be removed) device?

The short answer is to get the MAC address from the I/O Registry.
If you go to this link you can download a zip file which contains
an example showing the correct system calls to make.

Isn't there a more 'generic' unix method? This seems really apple
specific...
Like can I send a udp packet to myself or something.....

I remember from my old C++ class, an identifier called UUID that
provides classes for MAC functions. Google UUID and Linux and there
should be some examples. Theres gotta be a man page out there too.

Guess what?! It is a UUID that I'm trying to produce!
I believe there is a program called uuidgen but my google searches for
uuidgen.c don't seem to be pointing me to the code..
Anyone got a pointer to the source?
TIA.

Geez! It is easy to get a Mac Address. You just go to Rev's house, and
look at his door. I'm sure the address is right there.
Sigh...

Heh. Probably half the computers in my neighborhood are Macs so how
would he know it's me :-)

re-read you original post!
You specifically mentioned Mac OS X!!
*rage burns deep inside*
> Like can I send a udp packet to myself or something.....
Yeah, you probably can...
Then again, I think you need to be WAY MORE XXXXING CLEAR IN YOUR POSTS.
The only reason I am helping you at all is that I am bored as all hell.
Be grateful I hate my job. ;)
Anyway, and you better be real XXXXing thankful for this,
go to this link and you should be all set.

Google siocgifconf. It's the socket ioctl() that'll return a big buffer
that you pick through. It'll give you info on interfaces (IP address
and IP properties) and links (MAC addresses and so on). The interface
is complex enough that it'd be worthwhile to search around for some
example code.
The output of "netstat -in" maps pretty closely to what you'll get from
that programmatically. I think that includes the link info - not at my
mac now.
Here's an interesting search result. The 1993 date on this man page
worries me, but the basics look right. Way old versions didn't return
link information, just interfaces.

Good luck,
John
