In this tutorial, we are learning about how to restart the network interface in Linux. After you change the Server Network configuration file, you must restart the Server Network service for the changes to take effect.
Restarting the Network interface in Linux OS
The network interface in Linux OS is a configuration that allows computers and other devices to communicate across a network. It can be used to connect computers and other network devices to each other and the internet.
Ubuntu / Debian
Network Manager is a graphical tool used to configure networking services in Ubuntu. It allows users to easily manage wired and wireless connections, as well as configure other services such as DNS, proxy, and VPNs. It also provides a user-friendly, interface for managing all your network settings.
Use the following command to restart the server networking service.
sudo /etc/init.d/networking restart
or
sudo /etc/init.d/networking stop sudo /etc/init.d/networking start
or
sudo systemctl restart networking
Once this is done, use the following command to check the server network status.
sudo /etc/init.d/networking status
or
sudo systemctl status networking
NetPlan
NetPlan is a new network configuration utility for Linux systems that uses YAML to configure network interfaces. It was introduced in Ubuntu 18.04 and is the successor to the now deprecated ifup/down utility. Run the command below to update the network, and then any changes made to the network will take effect:
netplan apply
Conclusion
You should now have a good understanding of how to restart the network interface in Ubuntu. We have GUI mode also in Ubuntu where we can modify the IP addresses.
