Not all packet-capture progams work in promiscuous mode on all WLAN chipsets.  You may have one that's operating in 
normal mode.

ARP (or NDP in the v6 world) games will put you into the traffic stream without promiscuous sniffing, as was pointed 
out.

Hey all,

Has anyone run Firesheep to see that it does what it claims? I have run it both on a Windows XP box (with WinPCAP) and 
OS X and in each case I have not gathered any data outside of sites that I have visited myself. Perhaps I am 
misunderstanding what this application does. I am connected to an open network, heck both laptops are on the same 
network, same ssid, same AP even.

Thanks!

What should be routing best practices, disable arp poisoning.  (or at least detect and mitigate against)

On Cisco 'ip arp inspection vlan 1'

In light of the recent attention to “Firesheep” I am wondering if anyone is having issues and how they are addressing?
When used in conjunction with “Cain&Able” it appears able to sniff both wired and wireless traffic for login 
credentials and execute ARP Poisoning.
