Answer 1

On Windows, you need to provide a complete interface name / object, to be able to sniff on it.

First, have a look at what is available using IFACES.show() in a Scapy shell.

Then to get the interface, you can either use:

• iface = IFACES.dev_from_name("...") (or dev_from_pcapname, dev_from_id... have a look at help(IFACES) to see what’s available)
• iface = "the full name as printed above"

Then use it via sniff(iface=iface).

You could provide the pcap_name, but not the GUID: for instance, it would be something like \\Device\\NPF_{...} rather than just {...}.

Also, please use scapy 2.4.3rc1 (or at least 2.4.2) to be sure you’re up-to-date
