 DHCP Client? or Server?

If client, from my build doc:

Make it easy for user to switch between DHCP and static IP

 sudo cp -pi /etc/network/interfaces /etc/network/interfaces.dhcp
 sudo cp -pi /etc/network/interfaces /etc/network/interfaces.static1

 sudo vi /etc/network/interfaces.static1

 #iface eth0 inet dhcp
  iface eth0 inet static
    address 10.2.16.6
    netmask 255.255.255.252
    broadcast 10.2.16.7
    gateway 10.2.16.5

 sudo cp -pi /etc/network/interfaces.static1 /etc/network/interfaces.static

Set up address method selection scripts. Note that /usr/local/bin/setip
provides a dialog for setting IP, default gateway, etc

 sudo vi /usr/local/bin/switch2dhcp
 #
 /bin/cp -p /etc/network/interfaces.dhcp /etc/network/interfaces

 sudo vi /usr/local/bin/switch2static
 #
 /bin/cp -p /etc/network/interfaces.static /etc/network/interfaces


 sudo chmod 755 /usr/local/bin/switch2dhcp /usr/local/bin/switch2static


-------------------------

If you want to disable DHCP server:

Disable, DHCP. No accidents!

 vi /etc/dnsmasq.more.conf

 #dhcp-range=wlan0,10.1.10.10,10.1.10.250,24h
 #dhcp-range=eth1,10.1.20.10,10.1.20.250,24h
 #dhcp-range=eth2,10.1.30.10,10.1.30.250,24h
 #dhcp-range=eth3,10.1.40.10,10.1.40.250,24h
 dhcp-leasefile=/var/tmp/dnsmasq.leases


Reboot, or re-start dnsmasq
