This allows Wireshark to actually capture packets (without it, you can only view your archived captures). On a wired Ethernet card, promiscuous mode switches off a hardware filter preventing unicast packets with. The various network taps or port mirroring is used to extend capture at any point. Ctrl+ ↑ Or F7. (Changing libpcap to avoid using libnl, which should get rid of those issues, is. 1. Technically, there doesn't need to be a router in the equation. The only way to experimentally determine whether promiscuous mode is working is to plug your computer into a non-switching hub, plug two other machines into that hub, have the other two machines exchange non-broadcast, non-multicast traffic, and run a capture program such as Wireshark and see whether it captures the traffic in question. promsw C. Wireshark at the monitor port should show all Unicast packets coming from and going to the PC monitored, plus Broadcast/Multicast.
