Python网络:查找对应接口的MAC地址 [英] Python networking : find MAC address for corresponding interfaces

问题描述

我从 pmav99 找到了一个脚本.非常感谢他.

I has found a scripts from pmav99. Big thanks to him.

import socket
import psutil

def get_ip_addresses(family):
    for interface, snics in psutil.net_if_addrs().items():
        for snic in snics:
            if snic.family == family:
                yield (interface, snic.address, snic.netmask)

ipv4s = list(get_ip_addresses(socket.AF_INET))

print ipv4s

结果是:

[('Local Area Connection* 2', '169.254.189.147', '255.255.0.0'), ('Ethernet', '192.168.18.34', '255.255.255.0'), ('Wi-Fi', '192.168.1.102', '255.255.255.0'), ('Loopback Pseudo-Interface 1', '127.0.0.1', '255.0.0.0')]

但是在psutil的net_if_addrs()中，它还提供了每个接口的mac地址.那么如何将Mac地址添加到列表中呢? MAC地址的密钥名称也为地址.我找不到办法.

But in net_if_addrs() of psutil, it also provide mac-address of each interfaces. So how can i add the mac address to the list ? the keys name of MAC address also is address. I can't find the way to get it.

推荐答案

根据在文档中，MAC地址由家族psutil.AF_LINK标注.该代码片段将获取接口名称以及MAC地址的列表.

According to the documentation, MAC addresses are noted by family psutil.AF_LINK. This code fragment will get a list of interface names, along with the MAC addresses.

macs = list(get_ip_addresses(psutil.AF_LINK))
print macs

以下程序将产生从MAC地址到IPV4地址的映射:

The following program will produce a mapping from MAC addresses to IPV4 addresses:

import socket
import psutil

def get_ip_addresses(family):
    for interface, snics in psutil.net_if_addrs().items():
        for snic in snics:
            if snic.family == family:
                yield (interface, (snic.address, snic.netmask))

ipv4s = dict(get_ip_addresses(socket.AF_INET))
macs = dict(get_ip_addresses(psutil.AF_LINK))
mac2ipv4 = {macs[k][0]: ipv4s[k] for k in set(macs) & set(ipv4s)}

print mac2ipv4
