基于Linux的Python实现ARP检测防护软件设计模块包含能够获取局域网活动主机的MAC地址、IP地址能够检测防护ARP攻击行为并记录保存能够显示出ARP攻击源的MAC地址、IP地址。请用代码详细写出需要调用的py文件

1. 获取局域网活动主机的MAC地址、IP地址的py文件：

import os
import re

def get_mac_ip():
    arp_result = os.popen('arp -a')
    arp_lines = arp_result.readlines()
    mac_ip_dict = {}
    for line in arp_lines:
        match = re.search(r'(\d+\.\d+\.\d+\.\d+)\s+([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})', line)
        if match:
            ip = match.group(1)
            mac = match.group(0).split()[1]
            mac_ip_dict[ip] = mac
    return mac_ip_dict

2. 检测防护ARP攻击行为，并记录保存的py文件：

import time
import threading
from scapy.all import *

class ARPDetector:
    def __init__(self, timeout=5):
        self.timeout = timeout
        self.arp_packets = {}
        self.detector_thread = threading.Thread(target=self.detect_arp_attack)
        self.detector_thread.setDaemon(True)
        self.detector_thread.start()

    def detect_arp_attack(self):
        while True:
            for key in list(self.arp_packets.keys()):
                if time.time() - self.arp_packets[key]['time'] > self.timeout:
                    del self.arp_packets[key]
            time.sleep(1)

    def is_arp_attack(self, packet):
        if ARP in packet and packet[ARP].op == 2:
            if packet[ARP].psrc in self.arp_packets:
                if self.arp_packets[packet[ARP].psrc]['mac'] != packet[ARP].hwsrc:
                    print(f'ARP attack detected: {packet[ARP].psrc} is-at {packet[ARP].hwsrc}')
            else:
                self.arp_packets[packet[ARP].psrc] = {'mac': packet[ARP].hwsrc, 'time': time.time()}

detector = ARPDetector()

def arp_monitor():
    sniff(prn=detector.is_arp_attack, filter='arp', store=0)

if __name__ == '__main__':
    arp_monitor()

3. 显示出ARP攻击源的MAC地址、IP地址的py文件：

from scapy.all import *

def arp_display(packet):
    if packet[ARP].op == 1:
        print(f'IP: {packet[ARP].psrc} MAC: {packet[ARP].hwsrc}')

if __name__ == '__main__':
    sniff(prn=arp_display, filter='arp', store=0)
