[unisog] fw: insecure wireless LAN deployment at .edu

The way we have set up our system is as follows:

The campus is on DHCP (Unix).

DHCP gets its "assignments" from the hosts.master file.  Your address may 
be "dynamic" (meaning you can get an IP from any hot port) or static (only 
one port will work.)

If your MAC address isn't "registered" in the hosts.master file, you can't 
even login from a wireless LAN.

If your MAC address *is* registered *and* you are on the student 
residential  LAN, you get access only to an authentication device, and 
after you've logged in through that, you get an IP assignment.
