This document provides instructions for configuring a Dynamic Host Configuration Protocol (DHCP) server on a Linux system. It outlines the DHCP request/response process and describes how to install DHCP packages, edit the dhcpd.conf configuration file to define DHCP pools, client reservations, and service settings, and restart the DHCP daemon service. The configuration file is edited to set up a DHCP pool with an IP range, DNS, domain, and gateway options for the 192.168.10.0 subnet. A fixed IP is also assigned to a client using its MAC address. Firewall rules are added and reloaded to allow DHCP traffic.

1. Dynamic Host Configaration Protocol (DHCP) Configaration

2. DORA Process
D = discover
O = offer
R = request
A = acknowledge

3. Checking andinstalling Packages:
# rpm–qa | grepdhcp //check dhcppackages
# yum install dhcp* -y //install dhcppackages

4. DHCP Configuration
Server Name =dhcpserver
Package Name = dhcp
ConfigFile= /etc/dhcp/dhcpd.conf
ServiceName =dhcpd

5. Config & Editdhcpd.confFile
# vim/etc/dhcp/conf/dhcpd.conf
**comment all line except the below
**main partfor dhcp configaration***
subnet 192.168.10.0 netmask 255.255.255.0 {
range 192.168.10.2 192.168.10.254; //pool range
option domain-name-servers dns.mmc.com; //host_domain name
option domain-name "mmc.com"; //domain name
option routers 192.168.10.1; //gateway
option broadcast-address 192.168.10.255; //broadcast
default-lease-time 600; //lease time
max-lease-time 7200;
}
**fixed IPin DHCP server using MACaddress
host fantasia {
hardware ethernet 08:00:07:26:c0:a5; //client MACaddress
fixed-address fantasia.fugue.com; //client host_domain name
}
# cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf //copydhcpconfigfile

7. Restart Service
# systemctl restart dhcpd //start service
# systemctl enable dhcpd //enable service
# firewall-cmd --permanent--add-service=dhcp //alow firewall
# firewall-cmd --reload //reload firewall
