I am really new to Wireshark, and I am little confused about the term capture interface. I see a list of about 9 to 10 so-called interfaces. What are they? I mean, I have only one Ethernet interface card and a wireless card, with each providing one interface, which makes two interfaces(?), doesn't it? But how is that Wireshark tells me there are 9 interfaces?
These are virtual interfaces that exist on your machine. If you do
There are more interfaces under the hood than just the two physical interfaces that you can see.
