How do you configure DHCP in Linux operating system?

Answer 1

DHCP support is already included in every distro capable of networking. It isn't a program; it's a basic part of the TCP/IP protocol.

Answer:

Well, if you are referring to the DHCP client, the program /sbin/dhclient is likely already installed on your Linux distro of choice.

If you would like to run a DHCP server for one or more DHCP client machines or devices, you would go to www.isc.org and download the dhcp.x.x.x package (whatever the latest and greatest version is) and compile it on your Linux host machine. After compilation, configure it as desired, launch dhcpd (usually via the service command or directly from /etc/init.d), the DHCP daemon and you're ready to boot your DHCP clients.

Answer 2

DHCP is sub-divided into two categories, DHCP Server and DHCP Client. Your question does not specify which you wish to configure.

However, very loosely, with DHCP Server you need to configure a pool of assignable IP addresses etc. and start up the 'dhcpd' daemon.

Likewise, very loosely, with DHCP Client, you need to configure 'dhclient' to be executed at the appropriate time.

The above assumes you're using the DHCP software found at ISC.ORG. (Nearly everyone does anyway, in one way or another.)

For a more specific response, you must specify which you wish to configure, the server or the client.
