[Snort-users] Wireless IDS setup experience

I am not sure either but when I was asking about it no one responded
saying that snort has integrated it. 
Also the front ends such as BASE and ACID don't show wirless graphs in a
percentage bar graph like it does for UDP and TCP traffic.

So I am not sure

Will.

Hi, I got snort 2.30, which mentioned it supports wirelesss IDS: # grep

WISHLIST faq.pdf faq.tex work/snort-2.3.0/doc/signatures/1966.txt:This
event is generated when an 
attempt is made to discover sensitive information associated with a 
Global Sun Technology wireless access point.

And the README.wireless said that:
Regular Snort, wireless interface:
---------------------------------
To use Snort over a wireless interface in RFMON mode, simply set the
card to that mode and start snort with the usual -i <interface> flag.
How is sniffing in RFMON mode different from sniffing in Ethernet
emulation mode (that is, the mode the card is usually in when you are
operating on your own network)? In RFMON mode the card is associated
with no particular network, rather it listens to all traffic it can see
from any device using 802.11 within range. Similar to using different
Virtual LANs on the same piece of wire, many 802.11 networks operate in
the same area. For those interested in monitoring only their own
network, it is recommended that they leave their wireless card in
Ethernet emulation mode. This is no different than snort in the wired
environment (and, in fact snort won't even know the difference). For
those interested in monitoring all wireless networks within range, RFMON
mode should be used.

...

I m not sure if snort-wireless had already integrated into snort.2.30.
