python scapy "unknown pypcap network interface '\\Device\\NPF_Loopback'"

Question

I've an issue with scapy trying to run the following code:

if __name__ == '__main__':
    sniff(filter="ip",prn=packet_received, count=10)

(assume that packet_received is the callback method) I expect to get some packets but I got this error:

Unknown pypcap network interface '\Device\NPF_Loopback'

I've seen this thread: Unknown pypcap network interface 'eth0' error with python2 scapy on windows 10 machine and tried what the guy there said but it didn't worked, anyone know what is the issue?

I dont know if it matter (guess it is according to the forums) I am connected to the internet via external network adapter

Thanks for the help guys.

Answer 1

Run this command in cmd if you are using windows:

net start npcap

That worked for me
