AttributeError: module 'socket' has no attribute 'AF_PACKET'

Question

I am working on building a packet sniffing program using Python, however I have hit a speed bump. For some reason I think socket has not imported properly, because I am getting the following message when my program is run: AttributeError: module 'socket' has no attribute 'AF_PACKET'

I am using OS X and Pycharm is my IDE and I am running the latest version of Python if that helps.

Anyways here is my complete program so far:

import struct
import textwrap
import socket

def main():
    connection = socket.socket(socket.AF_PACKET, socket.SOCKET_RAW, socket.ntohs(3))

    while True:
        rawData, address = connection.recvfrom(65535)
        reciever_mac, sender_mac, ethernetProtocol, data = ethernet_frame(rawData)
        print('\nEthernet Frame: ')
        print('Destination: {}, Source: {}, Protocol: {}'.format(reciever_mac, sender_mac, ethernetProtocol))

# Unpack ethernet frame
def ethernet_frame(data):
    reciever_mac, sender_mac, protocol = struct.unpack('! 6s 6s H', data[:14])
    return getMacAddress(reciever_mac), getMacAddress(sender_mac), socket.htons(socket), data[14:]

# Convert the Mac address from the jumbled up form from above into human readable format
def getMacAddress(bytesAddress):
    bytesString = map('{:02x}'.format, bytesAddress)
    macAddress = ':'.join(bytesString).upper()
    return macAddress

main()

Thanks for any help in advance!

Actually, AF_PACKET doesn't work on OS X, it works on Linux.

AF_PACKET equivalent under Mac OS X (Darwin)

So you're saying I must continue my development on a Linux machine? – Ahad Sheriff Jul 16 '16 at 01:18
Would `(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_IP)` work? – Ahad Sheriff Jul 16 '16 at 01:34
You can run Linux on VirtualBox. Actualy i don't know exact whether these socket protocol families work on OS X. You can try it! – Jing Jul 16 '16 at 02:43

Well that explains why it doesn't work, though I'd much prefer an exception than literal code not being available on a platform – Allison Nov 18 '17 at 01:23
What is the equivalent on windows? – X0-user-0X Jun 14 '22 at 14:38

I ran into this issue on macOS 10.13.1, using Python 3.6.3 and this cool scapy fork that is compatible with python3.

I was using version 0.22 of that tool and as suggested in this issue downgrading to version 0.21 fixed this issue!

In case scapy is not a viable alternative, you could also try the pcap library as suggested in this post (although using python 2 seems to be necessary here).
