ArpFile

class getmac.getmac.ArpFile

Bases: Method

Use the contents of /proc/net/arp to find the MAC address of a host.

Only complete entries are used. Incomplete, failed and proxy ARP entries are ignored, since the kernel keeps the last known (possibly stale) MAC for failed entries, and proxy ARP entries don’t have a real MAC.

Attributes Summary

method_type	The type of method, e.g. does it get the MAC of a interface.
platforms	Platforms supported by a method.

Methods Summary

get(arg)	Core logic of the method that performs the lookup.
test()	Low-impact test that the method is feasible, e.g. a command exists.

Returns:

Lowercase colon-separated MAC address, or None if one could not be found.

test()

Low-impact test that the method is feasible, e.g. a command exists.
