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.

Have you installed Npcap ? Try to update it – Cukic0d
Sorry for the question, but what Npcap will help me? thanks – DBS
If you're on Windows, you need to have Npcap installed to use Scapy, as stated in the documentation: scapy.readthedocs.io/en/latest/installation.html#windows – Cukic0d
That worked, thank you very much! – DBS

Run this command in cmd if you are using windows:

net start npcap

That worked for me
