Read MAC address in Linux

j777

Hello,

Is there a way to read the MAC address of a linux system directly? ie not from the output of arp or ifconfig ---> Where does ifconfig read the MAC address from?

Thanks

It reads it from the kernel. You can probably find it somewhere in the /proc filesystem.. I'll browse around.

Parsing the output, as you suggested, is one way. Looking at a socket object is another. I think this would probably be the best way to do it under Linux.

Here's an example of how one might do this in Python:

Code:

import socket
sock = socket.socket (socket.AF_PACKET,socket.SOCK_RAW)
sock.bind (("eth0", 9999))
mac = s.getsockname()[-1]

j777

I actually just found this example which works.

Thanks for the help chroot and Sane.

Haha, yes. That's exactly what I had suggested.

It looks at a socket object to see the MAC address.
