How to Install ifconfig on Debian

Do you see ifconfig command not found error in Debian? Here is my quick tutorial on how to install it on Debian.

 

I have made fresh install of Debian 12 server on my VM and  i wanted to check IP of VM and I have encountered the problem:

 The ifconfig package is not included by default in Debian since it is being phased out in favor of the ip command. The ip command now handles tasks such as modifying or displaying routing, network devices, interfaces, and tunnels."

 If we still want to use the good old ifconfig command, you'll have to install it explicitly.

 

Installing ifconfig command in Debian 

The ifconfig is not a package in its own. It is installed with net-tools package that has some additional networking tools. 

So to get ifconfig, you need to install net-tools package like this:

sudo apt install net-tools

After install you can use the command:

However, I strongly advise you should start using the IP command. Sooner or later, net-tools will be completely deprecated and you won't be able to install it.
