python: using raw socket with OSX -

i found code online , found doesn't work on osx. know correct method without using third party library?

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’:         continue     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 

apparantly osx not have af_packet or pf_packet , af_inet high level think, or @ least requires more recoding drop in replacement.

thanks

ok figured 1 out, on mac have use pcap library. here code came with.

#!/usr/bin/env python2.7  import sys, binascii, subprocess import dpkt, pcap, socket  cottonelle = 'f0272d8b52c0'  def main():     name = pcap.lookupdev()     try:         pc = pcap.pcap(name)     except:         print pc.geterr()      try:         print 'listening on %s' % (pc.name)         ts, pkt in pc:             eth = dpkt.ethernet.ethernet(pkt)             ip_hdr = eth.data             if eth.type != dpkt.ethernet.eth_type_arp:                 continue             if binascii.hexlify(eth.src) == cottonelle:                 subprocess.call("/usr/local/bin/stopsim", shell=true)     except exception e:         print e, pc.geterr()  if __name__ == '__main__':     main()
