# Desc:	Setting up a DHCP server on a LAN with Ubuntu 9.10

# Install DHCP3
sudo apt-get install dhcp3-server

# Specify the interface(s) that dhcp3-server should manage
# in /etc/default/dhcp3-server
INTERFACES="eth0"

# Set a static IP for the DHCP server itself on the
# interfaces that it will manage in /etc/network/interfaces
auth eth0
iface eth0 inet static
    address 192.168.72.1
    netmask 255.255.255.0
    network 192.168.72.0
    gateway 192.168.72.254
    broadcast 192.168.72.255

# Edit the etc/dhcp3/dhcpd.conf configuration file
# I'm going to be running a 192.168.72.0 host-only 
# vmnet on eth0 with fixed addresses for several machines 
# in my example here
ddns-update-style none;
log-facility local7;
