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 toher DHCP servers running on your network. I can cause hours of debugging, both the newly installed server, but also people asking why the DNS is not updated.

Install the DHCP server.

apt-get install isc-dhcp-server

Configure the server

Stop the server

service isc-dhcp-server stop

Choose Network Deevice

Edit /etc/default/isc-dhcp-server and set the dhcp server to run on eth0.

INTERFACESv4="eth0"

Start the server

service isc-dhcp-server start
