Ok, This thread is exactly what I am trying to do myself. I just have a few problems that I need to solve.

What I have working: Evil Ap, Aireplay is doing a massive DDOS to the victims AP, All clients are not associated and are probing the ESSID.

Ok, so the basics is done

Now I need to get the DHCP server up and running to assign ip address's to the clients.

I downloaded dhcp-3.0.7 from the ISC site, but I am having problems installing it. Not sure if its compatible with Backtrack3. Any ideas here? This is the error is piping to me

create a file named /etc/dhcpd.conf and put this in it

option subnet-mask;
option routers;
filename "pxeboot";

ddns-update-style none;

option domain-name "google.com";
option broadcast-address;
option domain-name-servers;
server-name "DHCPserver";

default-lease-time 7200;
max-lease-time 7200;

subnet netmask {

and run "dhcpd ath0", this will serve ip address to any one that connects.
Hope it helps, command are on bt3
