ARP request without reply raw sockets python

Question

I'm trying to get a arp reply after send ARP request but the reply is not comming.

I had a look to wireshark for the results and i think he does the broadcast to the network, but no reply show up...

In results of wireshark the MAC addr of sender and receiver is do not correspond to the real MAC addr, im bealive i'm not packing this right but i dont understand why.

need help...

#!/usr/bin/env python3

import struct
import socket



raw = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(0x0806))
raw.bind(("wlp3s0", socket.htons(0x0806)))


mac_local = b"ff:ff:ff:ff:ff:ff"   # mac de quem envia request
ip_local = "192.168.1.7"           # ip de quem envia request
mac_dest = b"00:00:00:00:00:00"    # mac de quem recebe request
ip_dest = "192.168.1.2"            # ip de quem recebe request




# Ethernet Header
protocol = 0x0806             # 0x0806 protocol to ARP
ethernet_header = struct.pack("!6s6sH", mac_dest, mac_local, protocol)


# ARP header

type_hardware = 1
type_protocol = 0x0800       # IPV4
size_addr_hardware = 6   # Refere ao tamanho do endereço do MAC que é 
48 bits  == 6 bytes 
size_addr_protocol = 4  # Refere ao tamanho do endereço do ipv4 que é 
32 bits == 4 bytes
operation = 1                  # 1 = request / 2 = Reply 

source_ip = socket.inet_aton(ip_local)
dest_ip = socket.inet_aton(ip_dest)


arp_addr = struct.pack("!HHBBH6s4s6s4s", type_hardware, type_protocol,
                       size_addr_hardware, size_addr_protocol, operation,
                       mac_local, source_ip, mac_dest, dest_ip)
pkt = ethernet_header + arp_addr

cont = 0
while cont < 6:
    raw.send(pkt)
    cont +=1

Answer 1

I'm somehow confused about the accepted answer.

Is MAC 00:00:00: 00:00:00 not a valid MAC from XEROX?

https://hwaddress.com/company/xerox-corporation/

When I see ARP-request captured with e.g wireshark

then mac adresses in requests are always like

MAC_DST: FF:FF:FF:FF:FF:FF  //mac broadcast
MAC_SRC: MAC-address of requester

the mac adresses in reply would then be

MAC_DST: MAC-adress of requester
MAC_SRC: MAC-address of replier
