The file /etc/default/dhcp3-server contains the reference to the interface where the service needs to listen to.
# Defaults for dhcp initscript # sourced by /etc/init.d/dhcp # installed at /etc/default/dhcp3-server by the maintainer scripts # # This is a POSIX shell fragment # # On what interfaces should the DHCP server (dhcpd) serve DHCP requests? # Separate multiple interfaces with spaces, e.g. "eth0 eth1". INTERFACES="eth0"
The file /etc/dhcp3/dhcpd.conf is the configuration file of the server.
