How to Manage network interfaces on Ubuntu server 24.04

To manage network interfaces on Ubuntu Server 24.04, follow the steps below:

Step 1 : Use the ip command for managing network interfaces:

ip addr show

Step 2 : Alternatively, you can use the shorthand command ip a for the same purpose.

ip a

Step 3 : To bring an interface down and then up (for example, enp0s3), use the following commands:

sudo ip link set enp0s3 down
sudo ip link set enp0s3 up

Step 4 : Another tool for managing network interfaces is ifconfig, but it's not installed by default on Ubuntu Server 24.04.

Step 5 : Install the net-tools package to get ifconfig:

sudo apt install net-tools

Step 6 : Once installed, you can use ifconfig to show network interface information:

ifconfig

Step 7 : Similar to the ip command, you can bring an interface down and then up using ifconfig:

sudo ifconfig enp0s3 down
sudo ifconfig enp0s3 up

Congratulations! You have successfully managed network interfaces on your Ubuntu Server 24.04 system.
