Python Raw Socket to Ethernet Interface (Windows)

Question

I\'m trying to create a DHCP Server and the first step is for me to send packets through my ethernet port. I\'m trying to send packets to my Ethernet interface and having an

Answer 1

As said multiple times already, ETH_P_ALL is not implemented on Windows, due to Win32 limitations. The alternative is called Winpcap (more recently Npcap), which sets up Windows to access such low-level things (it adds an extra driver)

What you can do then is to use a Winpcap/Npcap based library such as Scapy, to access Raw low-level sockets. This requires to install Npcap (or Winpcap) on the computer.

Then you can either use the library as-is (it has lots of capabilities of handling packets), or if you want to have access to the raw data

from scapy.all import *
IFACES.show() # let’s see what interfaces are available. Windows only
iface = <<"full iface name">> or <> or <>
socket = conf.L2socket(iface=iface)
# socket is now an Ethernet socket
### RECV
packet_raw = socket.recv_raw()[0]  # Raw data
packet_decoded = socket.recv() # Using the library (also contains things like sent time...)
### SEND
socket.send(b"\x00......"). # send raw data
socket.send(Ether()/IP(dst="www.google.com")/TCP()/Raw(load=b"data")) # use library
