Cryptography is complicated, and the standards are constantly changing to be more secure. The Windows VM communicates normally with the outside network. Wireshark shows interfaces en0, en1, en3 and lo0, but ifconfig shows vmnet1 and vmnet8 I want to sniff traffic between the Mac host and a Windows VM (NAT), but the traffic never shows up in Wireshark.

I'm trying to sniff traffic between my Leopard (10.5.7) host using Wireshark 1.0.2. Just like running tcpdump -D vs sudo tcpdump -D, the first one won't show any of the interfaces, won't compalain/prompt for sudo privileges either. You need to be superuser in order to be able to view interfaces. For.nix OSes, run wireshark with sudo privileges. If you are running Wireshark 1.4 or later on a.BSD, Linux, or macOS system, and it's built with libpcap 1.0 or later, for interfaces that support monitor mode, there will be a 'Monitor mode' checkbox in the Capture Options window in Wireshark, and a command line -I to dumpcap, TShark, and Wireshark.
