Packet Sniffing Error

Question

I'm running the following script:

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_TCP)

while True:
  print s.recvfrom(65565)

However, I get this error:

Traceback (most recent call last):
  File "supersecretfilepath/error.py", line 6, in <module>
    print s.recvfrom(65565)
error: [Errno 10022] An invalid argument was supplied

I'm running Python 2.7 on Windows. Thank you.

Answer 1

s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_TCP)

Perhaps your operating system doesn't support raw IPv4 sockets with TCP specified as the protocol.

What is it you're trying to do here?
