Download and install the dhcp3-server package

sudo apt-get install dhcp3-server

Specify the interfaces dhcpd should listen to in /etc/default/dhcp3-server, for example:

INTERFACES="eth1" 

Configure the interface used in /etc/network/interfaces, for example:

auto eth1
iface eth1 inet static
    address 192.168.0.1
    netmask 255.255.255.0
    gateway 192.168.0.254

Edit /etc/dhcpd.conf, for example:

To start/stop/restart the service or to check the status:

sudo /etc/init.d/dhcp3-server start
sudo /etc/init.d/dhcp3-server stop
sudo /etc/init.d/dhcp3-server restart
sudo /etc/init.d/dhcp3-server status
