How to Change the Name of Your Network Interface on CentOS 7398

The network interface name is important for identifying the network card in your system. If you have multiple network cards, it is essential to give them different names to avoid confusion. The default network interface name in CentOS 7 is eth0. However, you can change this name to anything you want.

There are two ways to change the network interface name in CentOS 7: using the command line or using a graphical user interface (GUI).

Using the Command Line

To change the network interface name using the command line, you will need to edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file. This file contains the configuration settings for the eth0 network interface. Open the file in a text editor, and find the line that begins with NAME=eth0. Change the name after the equal sign to the new name you want to use. For example, to change the name to eth1, you would change the line to NAME=eth1.

Once you have made the change, save the file and exit the text editor.

To apply the changes, you will need to restart the network service. You can do this by running the following command:sudo systemctl restart network

Once the network service has restarted, the network interface name will be changed.

Using a GUI

If you prefer to use a GUI, you can change the network interface name using the NetworkManager tool. To open NetworkManager, click on the network icon in the top-right corner of the screen and select Network Settings.

In the Network Settings window, click on the Wired tab and select the network interface you want to change. Then, click on the Edit button.

In the Edit Connection window, click on the General tab and change the Name field to the new name you want to use. For example, to change the name to eth1, you would change the field to eth1.

Once you have made the change, click on the Save button and close the Edit Connection window.

The network interface name will be changed immediately.

Conclusion

Changing the network interface name is a simple process that can be done using either the command line or a GUI. By following the steps in this guide, you can easily change the name of your network interface to anything you want.
