If you're using the ISC DHCP server (which ships with most Linux and BSD
systems) it's configured from the command line, e.g.

    dhcpd -q eth0

Configuring this varies from distribution to distribution.  Under OpenBSD
it's configured in /etc/rc.conf.  Under Red Hat it's probably down in
/etc/sysconfig somewhere.  I'm not sure about other systems.
