Linux Box as a DHCP Server

Operating System: Centos 6.3

In this setup, client machines on the LAN are assigned IP addresses automatically unlike the previous setup where IP addresses were being assigned manually.

To configure;

Install dhcp package via terminal;

[root@telweb]# yum install dhcp* -y

Copy the available sample dhcp configuration at /usr/share/doc/dhcp*

[root@telweb]# Cd  /usr/share/doc/dhcp*
[root@telweb]# Cp dhcpd.conf.sample /etc/dhcp/dhcpd.conf
If asked to replace the existing dhcpd.conf at /etc/dhcp/ , answer with an yes.

To configure the dhcp, edit the file /etc/dhcp/dhcp.conf
[root@telweb]# Vi /etc/dhcp/dhcpd.conf

Go to the section highlighted below and edit it to suit your network;
--------------------------------------------------------------------------------------------------------------------
# A slightly different configuration for an internal subnet.

subnet 192.168.2.0 netmask 255.255.255.0 {
  range 192.168.2.50 192.168.2.100;
  option domain-name-servers 8.8.8.8;
  option domain-name "net.telweb.com";
  option routers 192.168.2.1;
  option broadcast-address 192.168.2.255;
  default-lease-time 600;
  max-lease-time 7200;
}
--------------------------------------------------------------------------------------------------------------------


Then save the file



Done!!
