python中如何使用raw socket收發arp package

Question

我需要“在一個程序中發送和接收ARP數據包”。 我知道scapy包已經很安靜了，你只需要傳遞一些參數。 但是，我想知道的不僅僅是傳遞參數。 所以，如果你推薦scapy作為答案，它可能無濟於事。

代碼

python
import struct
import socket
import binascii

rawSocket = socket.socket(socket.PF_PACKET, socket.SOCK_RAW,
                          socket.htons(0x0003))
rawSocket.bind(("wlp5s0", socket.htons(0x0003)))

source_mac = binascii.unhexlify('00:A0:C9:14:C8:29'.replace(':', ''))
#b'\x00\x00\x00\x00\x00\x00' sender mac address
dest_mac = binascii.unhexlify('ff:ff:ff:ff:ff:ff'.replace(':', ''))
#  b'\xff\xff\xff\xff\xff\xff'  target mac address

source_ip = "192.168.100.3"  # sender ip address
dest_ip = "192.168.100.1"  # target ip address

# Ethernet Header
protocol = 0x0806  # 0x0806 for ARP
eth_hdr = struct.pack("!6s6sH", dest_mac, source_mac, protocol)

# ARP header
htype = 1  # Hardware_type ethernet
ptype = 0x0800  # Protocol type TCP
hlen = 6  # Hardware address Len
plen = 4  # Protocol addr. len
operation = 1  # 1=request/2=reply
src_ip = socket.inet_aton(source_ip)
dst_ip = socket.inet_aton(dest_ip)
arp_hdr = struct.pack("!HHBBH6s4s6s4s", htype, ptype, hlen, plen, operation,
                      source_mac, src_ip, dest_mac, dst_ip)

packet = eth_hdr + arp_hdr
rawSocket.send(packet)
rawSocket.recvfrom(65535)
```
By the way I can clear see the packet already send and reply but `Wireshark`

Answer 1

進行綁定時，應將第二個參數設置為 0：rawSocket.bind(("wlp5s0", 0))

我能夠收到ARP數據包沒問題
