Hello, I was wondering if it is possible to capture TCP traffic between machines other than the one running Wireshark over WiFi.

Thanks

Yes. See the wiki page on WLAN Capture setup for more info.

Thanks for the reply! Unless I’m mistaken I think that page tells me to use monitor mode. But when I use monitor mode I only get 802.11 packets. Am I using the wrong mode or is this perhaps a limitation of my network driver?

EDIT: I’m using the latest version of Mac OS X right now. I’m not sure if there are any limitations on this platform or not.

EDIT 2:Just realized this is happening because the traffic I am sniffing is on an secured network. Pardon my mistake.
