NetstatNetToMedia

class getmac.getmac.NetstatNetToMedia

Bases: Method

Use netstat -p to find the MAC address of a host in the “Net to Media Table” (the ARP table for IPv4, and the NDP neighbor cache for IPv6) on Solaris and illumos.

Unlike arp, this works for IPv6, and doesn’t fail when the host isn’t in the table. It doesn’t need root.

A link-local IPv6 address can include a zone, as the interface name (fe80::1%net0) or index (fe80::1%2).

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.

Attributes Documentation

method_type: str = 'ip'

The type of method, e.g. does it get the MAC of a interface.

Allowed values:

• ip

• ip4

• ip6

• iface

• default_iface

platforms: set[str] = {'sunos'}

Platforms supported by a method.

Methods Documentation

get(arg)

Core logic of the method that performs the lookup.

Warning

If the method itself fails to function an exception will be raised! (for instance, if some command arguments are invalid, or there’s an internal error with the command, or a bug in the code).

Parameters:

arg (str) – What the method should get, such as an IP address or interface name. In the case of default_iface methods, this is not used and defaults to an empty string.

Return type:

Optional[str]

Returns:

The raw value the technique found, or None if nothing was found. It isn’t cleaned up, so it may not be a lowercase colon-separated MAC (get_mac_address() runs it through clean_mac()). For default_iface methods, it’s the name of an interface instead of a MAC.

test()

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

Return type:

bool
