DHCP Primary
Network
We will give the DHCP primary a static IP-address. Edit /etc/networking/interfaces and make the following changes.
# The primary network interface #allow-hotplug eth0 #iface eth0 inet dhcp auto eth0 iface eth0 inet static address 192.168.1.36 network 192.168.1.0 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.1
Software
Before installing the DHCP server, make sure that you do not have other DHCP servers running on your network. It can cause hours of debugging.
Install the DHCP server.
apt-get install isc-dhcp-server
Configure the server
Stop the server
service isc-dhcp-server stop
Choose Network Device
Edit /etc/default/isc-dhcp-server and set the dhcp server to run on eth0.
INTERFACESv4="eth0"
Get the DDNS update key
Copy your DDNS update key from the DNS Master and save it in /etc/dhcp/ddns-update.dnskey.
Edit dhcpcd.conf
Comment out all lines in /etc/dhcp/dhcpd.conf and add the following to the bottom of the file:
include "/etc/dhcp/ddns-update.dnskey"; include "/etc/dhcp/dhcpd.conf_primary"; include "/etc/dhcp/dhcpd.conf_subnet"; include "/etc/dhcp/dhcpd.conf_static";
Start the server
service isc-dhcp-server start
