RE: Wi-Fi Security - setup of AirSnarf

        I can't help you with Airsnarf, but I did demo a product from
SonicWall just before it was released. It's a WiFi gateway with built-in
VPN and works very well for a small user base.
http://www.sonicwall.com/products/sohotzw.html. I've also used a product
from Proxim, http://www.orinocowireless.com/solutions/hotspot/ and it
worked VERY well for a public access solution. 

        Wifi is not that dangerous of a technology, all you need to do
is design it right. At work, I've setup a WiFi AP, but I've placed it in
my DMZ which is already secure. When someone wants to access the network
I map an IP from the firewall to that MAC and grant it an x hour pass to
the system. Then close the hole and remove the ARP entry. I'm working on
setting up a special DMZ for this purpose using *NIX and Net filter
(seaming I can automate it via PERL and shell scripts). Personally for
Internal WiFi I use Cisco Aironet AP's
(http://www.cisco.com/en/US/products/hw/wireless/index.html) great range
and power with good security.

Subject: Wi-Fi Security - setup of AirSnarf

Hi,
My company wants to set up a Wi-Fi solution for giving
clients Internet access

From a security point of view, I feel that it is not a
secure enough solution

I want to use Airsnarf (http://airsnarf.shmoo.com/) as
a 'proof-of-concept' on the security issues with Wi-Fi
solution to present to management

Has anyone tried Airsnarf?

I wanted some help on how to set it up and running, in
particular:

- what NIC do i have to install on my pc, can a
Wireless adapter used on client pc's be used to act as
an AP?

if someone has setup Airsnarf please help...

thanking u very much,
Ronish
