Has anyone successfully utilized Dsniff to capture packets on a wireless network? If so can you provide details to how you configured the machine.
I've run dsniff in 802.11b environments with no problems using OpenBSD and an Aironet 4800 PCMCIA card. The Cisco equivalent works just as well. Dug Song, dsniff author, did it last year at the USENIX technical conference in San Diego. He then presented "Passwords Found on a Wireless Network" with his findings. The paper can be found on his homepage in postscript format at http://www.monkey.org/~dugsong/talks/usenix00.ps. I'm pretty sure he was using OpenBSD with one of the four 802.11b NIC's that were supported by OpenBSD at the time. Of course, the SSID for the conference was widely published so people attending USENIX could use the wireless network. So, that was a known variable. Still, I've used dsniff on wireless 802.11b networks with no problems on OpenBSD using Aironet pcmcia cards and a laptop. The biggest obstacles would be the SSID and WEP. If the network uses access points which broadcast the SSID or they use the same SSID as the company name, which is common, then it's no big deal. WEP, of course, can also be broken, since most people use static WEP keys. But, most people don't use WEP anyway. Regards, -- Joseph W. Shaw II Network Security Specialist/CCNA Unemployed.
