File: /etc/sysconfig/network-scripts/ifcfg-<network-device>

DEVICE=<network-device>

HWADDR=<MAC address of the card>

IPADDR=<IP of the PXE server>

PREFIX=<Number of bits set to one in your netmask>

ONBOOT=yes

BOOTPROTO=static

● Next configure the dhcp server to listen on the correct network interface (only necessary if the server has

more than one network card and should only provide the service on a specific card)

File: /etc/sysconfig/dhcpd

DHCPDARGS=<network-device>

● You then have to provide a minimal setup for the dhcp server. Below you can find an example of this

minimal setup. Feel free to vary the ranges, but remember to change the placeholders in brackets to

values that suit your environment.

File: /etc/dhcp/dhcpd.conf

ddns-update-style none;

authoritative;

subnet <your network> netmask <your netmask> {

range dynamic-bootp <first address> <last address>;

option domain-name-servers <IP of DNS server>;

option domain-name ".<your domain>";

option routers <IP of the default gateway>;

option broadcast-address <Broadcast IP>;
