Fix ifconfig Ubuntu 20.04 (Focal Fossa) - when you type ifconfig in your server maybe you get a message: command 'ifconfig' not found, but can be installed with:.... Its mean this Server edition doesn’t have ifconfig command pre-installed.
So for fix this problem you just need to install net-tools, run the command:
sudo apt install net-tools
#ubuntu #ubuntu_server #sysadmin #devOps
