getting mac addr of unknown interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I know how to get the MAC addr of a network interface whose IP address is 
known.

But what if the network interface has not been configured yet and doesnt 
have an IP address?

Is there a way (thru system calls) to know the mac addresses of all 
network interfaces in the machine?

Worst case i could grep the log files but that is so crude!

Regards,
Amit
