Configuration Information
Information on configuring the dhcp client can be found in
Chapter 14.
Note that you only want to start the dhcp server if you want to
issue LAN addresses over your network. The dhcp client doesn't need
this script to be used. Also note that this script is coded for the
'eth1' INTERFACE, which may need to be modified for your hardware
configuration. With that in mind the dhcp init.d script can be created
using the following commands.
cat > /etc/rc.d/init.d/dhcp << "EOF"
#!/bin/sh
# Begin $rc_base/init.d/dhcp
# Based on sysklogd script from LFS-3.1 and earlier.
# Rewritten by Gerard Beekmans - gerard@linuxfromscratch.org
source /etc/sysconfig/rc
source $rc_functions
case "$1" in
start)
echo "Starting DHCP Server..."
loadproc dhcpd -q eth1
;;
stop)
echo "Stopping DHCP Server..."
killproc dhcpd
;;
reload)
echo "Reloading DHCP Server..."
reloadproc dhcpd
;;

$0 stop
sleep 1
$0 start

echo "Usage: $0 {start|stop|reload|restart|status}"
exit 1

esac
# End $rc_base/init.d/dhcp

chmod 755 /etc/rc.d/init.d/dhcp
The lease file must exist on startup. The following command will
satisfy that requirement:
touch /var/cache/dhcp/dhcpd.leases
The follow commands will create a base configuration file for a
dhcp server. There are several options that you may want to
add (information that is passed back to the dhcp client) and those are
covered in the man pages for dhcp.conf.
cat > /etc/dhcpd.conf << "EOF"

max-lease-time 144000;

All addresses should be changed to meet your circumstance.
