Please note that if you are installing the DHCP server for the first
time you need to configure it first. Please stop (/etc/init.d/dhcp
stop) the DHCP server daemon, edit /etc/dhcpd.conf to suit your needs
and particular configuration, and restart the DHCP server daemon
(/etc/init.d/dhcp start).

You also need to edit /etc/default/dhcp to specify the interfaces dhcpd
should listen to. By default it listens to eth0.

NOTE: dhcpd's messages are being sent to syslog. Look there for
diagnostics messages.

Starting DHCP server: dhcpd failed to start - check syslog for diagnostics.
