In this tutorial, we will show you how to fix Ifconfig
command not found on Ubuntu 20.04 LTS. For those of you who didn’t know, Interface configuration (ifconfig) is a command-line utility tool used to configure network interfaces in Unix and Linux operating systems. It displays the details of a network interface card like IP address, MAC Address, the status of a network interface card, etc. On Ubuntu 20.04 and before, ifconfig
the command by default used to ship. Whereas in minimal installed Ubuntu, I have not found ifconfig
a command. This was due to “net-tools” not being installed by default. Install “net-tools
” will solve the problem.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo
‘ to the commands to get root privileges. I will show you the step-by-step installation of Ifconfig
an Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
Prerequisites
- A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- A
non-root sudo user
or access to theroot user
. We recommend acting as anon-root sudo user
, however, as you can harm your system if you’re not careful when acting as the root.
