[FIXED] How can I find the MAC address of a client on the same network, using Python-Flask?

Issue

I am looking for a python way grab the client's MAC address. All requests are over the same network. I am looking for something similar to perform arp -n <Client_IP> on the router.

Solution

Not sure but you can always get IP address using the request object like

request.remote_addr and for that you have to

import request and then you can pass this IP to this function

import netifaces as nif

def mac_for_ip(ip):
    'Returns a list of MACs for interfaces that have given IP, returns None if not found'
    for i in nif.interfaces():
        addrs = nif.ifaddresses(i)
        try:
            if_mac = addrs[nif.AF_LINK][0]['addr']
            if_ip = addrs[nif.AF_INET][0]['addr']
        except IndexError, KeyError: #ignore ifaces that dont have MAC or IP
            if_mac = if_ip = None
        if if_ip == ip:
            return if_mac
    return None
