But if you install Wireshark does it capture traffic on the LAN (ie that doesn't begin or end with the current PC). I never had any luck with that on Windows.

- jmsguy 12y agoNot unless (a) your PC is routing traffic or (b) your PC is connected to a hub vs. a switch [1]. Unless one of these things is happening (even if your card is in promiscuous mode), those packets won't make it into your machine.

- whoopdedo 12y agoWhat about wireless traffic?
- dr_zoidberg 12y agoWireless cards can be put in promiscuous mode, and you'll see the packets that reach your computer, but maybe not all the traffic of the wireless network - this is known as the hidden node problem[1].

- noselasd 12y agoA wired LAN these days pretty much imply an ethernet switch, ethernet switches doesn't send you any frames that should go to another device if it knows which port that device is plugged into. You can't sniff traffic that doesn't reach your computer - so this isn't related to using Windows or Wireshark. Most managed ethernet switches have a span/mirror port though, where you can mirror all traffic to all ports out on a single port, so you can plug into that port to capture your LAN traffic.
