How can I find the MAC address of a client on the same network, using Python-Flask?
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 nifdef 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
If you get the gateway then you'll get the mac address corresponding to the interface that is using that gateway:
>>> gateway_iface = netifaces.gateways()['default'][netifaces.AF_INET][1]>>> netifaces.ifaddresses(gateway_iface)[netifaces.AF_LINK][0]['addr']'de:f2:fe:66:a4:8e'
