Re: user based IP address assginment

["daN." <dan () nesmail com>]

There is a way to do this but its kind of a pain.
1. Machine gets turned on.
2. gets assigned a non addressable IP via DHCP (different subnet if you are 
already behind a nat)
3. user goes to a webserver also on the non addressable network and enters 
username/password
4. executes a php script to take the MAC address out of the communications 
and modify dhcpd.conf to add a reservation for the newly logged in machine.
5. user runs winipcfg and hits release all/renew all. gets assigned the 
reserved IP now on the local network.

This doesn't add any security to your network because a user can always set 
their IP address manually .
