The DHCP package contains both the client and server programs for DHCP. dhclient (the client) is useful for connecting your computer to a network which uses DHCP to assign network addresses. dhcpd (the server) is useful for assigning network addresses on your private network.

You must have Packet Socket support compiled in the kernel and Socket Filtering either compiled in or as a kernel module.
Install DHCP by running the following commands:
./configure &&
make &&
make LIBDIR=/usr/lib INCDIR=/usr/include install
LIBDIR=/usr/lib INCDIR=/usr/include: This command installs the library and include files in /usr instead of /usr/local.
Information on configuring the DHCP client can be found in Chapter 14.
Note that you only need 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.
Install /etc/rc.d/init.d/dhcp init script included in the blfs-bootscripts-5.1 package.
make install-dhcp
The lease file must exist on startup. The following command will satisfy that requirement:
touch /var/state/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" default-lease-time 72000; max-lease-time 144000; ddns-update-style ad-hoc; subnet 192.168.5.0 netmask 255.255.255.0 { range 192.168.5.10 192.168.5.240; option broadcast-address 195.168.5.255; option routers 192.168.5.1; } EOF
All addresses should be changed to meet your circumstance.
The DHCP package contains dhclient, dhcpd and dhcrelay .
dhcpd implements Dynamic Host Configuration Protocol (DHCP) and Internet Bootstrap Protocol (BOOTP) requests for network addresses.
