## Modifica file DNS

dnsfile = open('/etc/dhcp3/dhcpd.conf','w')
dnsfile.write('ddns-update-style ad-hoc;\n')
dnsfile.write('default-lease-time 600;\n')
dnsfile.write('max-lease-time 7200;\n')

## Inserimento dati canale

channel_name = raw_input('Inserisci il nome del canale:')
channel_number = raw_input('Inserisci il numero del canale:')

## Impostazione base airmon-airbase

cmd_airbase = "airbase-ng -e"+channel_name+" -c"+channel_number+" mon0"
airmon_start = os.popen('airmon-ng')
airmon_start = os.popen('airmon-ng start wlan0')
airbase = os.popen(cmd_airbase)
airbase = os.popen(cmd_airbase)

## Impostazione base ifconfig

ifconfig = os.popen('ifconfig at0 up')
ifconfig = os.popen('ifconfig at0 192.168.2.129 netmask 255.255.255.128')
ifconfig = os.popen('route add -net 192.168.2.128 netmask 255.255.255.128 gw 192.168.2.129')

## Start DHCP

dhcp_start = os.popen('mkdir -p /var/run/dhcpd && chown dhcpd:dhcpd /var/run/dhcpd')
dhcp_start = os.popen('dhcpd3 -cf /etc/dhcp3/dhcpd.conf -pf /var/run/dhcpd/dhcpd.pid at0')

## Configurazione e impostazione IPTABLES

iptables = os.popen('iptables --flush')
iptables = os.popen('iptables --table nat --flush')
iptables = os.popen('iptables --delete-chain')
iptables = os.popen('iptables --table nat --delete-chain')
iptables = os.popen('echo 1 > /proc/sys/net/ipv4/ip_forward')
iptables = os.popen('iptables --table nat --append POSTROUTING --out-interface wlan1 -j MASQUERADE')
iptables = os.popen('iptables --append FORWARD --in-interface at0 -j ACCEPT')
iptables = os.popen('iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 192.168.1.1')
