Re: [Karlnet] RE: [isp-wireless] Re: DSSS security hole anounced

[Chris Conn <cconn@abacom.com>]

This vulnerability requires the device to use Carrier Sense Multiple 
Access with Collision Avoidance, the key here being the Collision 
Avoidance.  Karlnet does not use CA since it is based on a polling MAC 
and therefore does not utilize CSMA/CA.

So sleep easy, if actually you are to believe that someone would truly 
want to try this.
