本文介绍了使用Python编写的脚本，通过执行`arp-a`命令获取局域网中设备的IP地址、MAC地址，并尝试获取对应主机名，输出相关信息。

import socket
import struct
import os

def outputCmd(cmd):
    r = os.popen(cmd)
    text = r.read()
    r.close()
    return text

def getPCName(ip):
    return socket.gethostbyaddr(ip)


def getIpMacList():
    ipList = []
    arp_cmd = "arp -a" # 列出局域网所有 ip
    arp_result = outputCmd(arp_cmd)
    result = arp_result.split("\n")
    ipInfo = []
    total = len(result) - 3
    for idx in range(3,len(result)):
        item = {}
        line = result[idx]
        lineSplit = line.split(" ")
        ip = ''
        mac = ''
        notNullCount = 0
        for idx2 in lineSplit:
            if idx2 != "":
                notNullCount += 1
                if notNullCount == 1:
                    ip = idx2
                elif notNullCount == 2:
                    mac = idx2
        if ip == "":
            continue
        
        if mac == "":
            continue
        
        item['ip'] = ip
        item['mac'] = mac
