Ted Benson

Hey Ted, I got this working on my RasPi without all the scapy overhead (thanks to

Do you see any problem doing it this way?

import socket
import struct
import binascii
rawSocket = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, socket.htons(0x0003))
while True:
packet = rawSocket.recvfrom(2048)
ethernet_header = packet[0][0:14]
ethernet_detailed = struct.unpack(“!6s6s2s”, ethernet_header)
arp_header = packet[0][14:42]
arp_detailed = struct.unpack(“2s2s1s1s2s6s4s6s4s”, arp_header)
# skip non-ARP packets
ethertype = ethernet_detailed[2]
if ethertype != ‘\x08\x06’:
source_mac = binascii.hexlify(arp_detailed[5])
dest_ip = socket.inet_ntoa(arp_detailed[8])
if source_mac == ‘74c24671971c’:
print “Tide button pressed!, IP = “ + dest_ip
