Scapy sniffing on Windows

Question

I run this code as administrator:

from scapy.all import *
def poison(packet):
    packet[TCP].flags='R'
    sendp(packet)
sniff(prn=poison,filter='tcp',iface='any')

And I have error:AttributeError None Type object has no attribute encode
What should I do to make it work?

Answer 1

I don't think setting iface to "any" is valid under Windows.

You can check by removing the iface parameter from your code (or by using a valid interface name).
