./configure
make

sudo make install
cd ../common
sudo make install
cd ../dhcpctl
sudo make install
cd ../opamip
sudo make install

ok, now type sudo pico dhcpd.conf

## /etc/dhcpd.conf file
ddns-update-style ad-hoc;

subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.200;
default-lease-time 300000;
max-lease-time 350000;
option routers 192.168.1.1;
option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;
option domain-name-servers 192.168.1.1;
option nntp-server 17.254.0.26;
}
