How to Uninstall and Install dhcp-helper Ubuntu 22.04

Updated: October 21, 2022

dhcp-helper is a DHCP and BOOTP relay agent. It listens for DHCP and BOOTP broadcasts on directly connected subnets and relays them to DHCP or BOOTP servers elsewhere. dhcp-helper is much smaller than dhcp3-relay package and it does not require the Packet Filter kernel facility to be present. This makes it a good choice for use on small or embedded systems. Unlike dhcp3-relay, dhcp-helper can be configured to forward DHCP requests as broadcasts, and therefore does not need to be given the IP address of the DHCP server, only the network in which it resides. In this tutorial, I will show you ways to install dhcp-helper Ubuntu 22.04.

Prerequisites

  • OS: Ubuntu 22.04 or older Ubuntu versions
  • Privileges: Ensure that you are able to execute the sudo commands line.
