本文介绍了一个Python脚本，使用Scapy模块来发现局域网内的所有设备。脚本发送ARP请求到广播MAC地址，询问目标IP，设置目的地MAC为广播MAC，接收并解析响应，最后打印出每个设备的IP地址和MAC地址。

NETWORK_SCANNER

Discover all devices on the network.
Display their IP address.
Display their MAC address.

Write the Python code using the scapy.all module.

Refer to: https://scapy.readthedocs.io/en/latest/installation.html

#!/usr/bin/env python

import scapy.all as scapy

def scan(ip):
    scapy.arping(ip)

scan("10.0.0.1/24")

ALGORITHM

Goal -> Discover clients on the network.

Steps:

1. Create arp request directed to broadcast MAC asking for IP.

Two main parts:

-> Use ARP to ask who has target IP.

-> Set destination MAC to broadcast MAC.

2. Send packet and receive a response.

3. Parse the response.

4. Print result.

Use the scapy module in this program.

EX: Python Script to discover the clients on the network.

#!/usr/bin/env python

import scapy.all as scapy

def scan(ip):
    arp_request = scapy.ARP(pdst=ip)
    broadcast = scapy.Ether(dst="ff:ff:ff:ff:ff:ff")
    arp_request_broadcast = broadcast/arp_request
    answered_list = scapy.srp(arp_request_broadcast, timeout=1, verbose=False)[0]

    print("IP\t\t\tMAC Address\n------------------------------------------")
    for element in answered_list:
        print(element[1].psrc + "\t\t" + element[1].hwsrc)

scan("10.0.0.1/24")
