Enabling Networking and Wireless via Command Line

Ubuntu 16

In the world of system administration, the command line is a powerful tool that gives you direct control over your system. One of the many tasks you can perform from the command line is enabling networking and wireless. This article will guide you through the process, explaining each command and its parameters.

Quick Answer

Enabling networking and wireless via the command line is possible using various commands on different Linux systems. On Ubuntu systems, you can use the "nmcli" command to enable networking and wireless. On general Linux systems, you can use the "networking" service to enable networking and the "nmcli" command to enable wireless.

Understanding the Command Line

The command line, also known as the terminal, is a text-based interface where you can type commands to perform certain tasks. It’s a powerful tool that can give you more control over your system than a graphical user interface (GUI).

Enabling Networking

Networking is a crucial part of any system, as it allows communication between different systems. Here’s how you can enable networking via the command line.

Ubuntu 12.04 and Later

Ubuntu 12.04 and later versions use NetworkManager, a dynamic network control and configuration system. To enable networking, you can use the nmcli command:

nmcli networking on

nmcli is the command-line client for NetworkManager. The networking on parameter tells NetworkManager to enable networking.

General Linux Systems

On general Linux systems, you can use the networking service to enable networking. Here’s the command:

sudo /etc/init.d/networking start

sudo runs the command with root privileges. /etc/init.d/networking start starts the networking service.

Enabling Wireless

Wireless networking, or WiFi, is a crucial part of modern computing. Here’s how you can enable wireless via the command line.

Ubuntu Systems

On Ubuntu systems, you can use the nmcli command to enable wireless:

nmcli radio wifi on

nmcli is the command-line client for NetworkManager. The radio wifi on parameter tells NetworkManager to enable wireless.

General Linux Systems

On general Linux systems, you can use the nmcli command to enable wireless:

sudo nmcli radio wifi on

sudo runs the command with root privileges. nmcli radio wifi on tells NetworkManager to enable wireless.

Conclusion

The command line is a powerful tool for system administration. With the commands explained in this article, you can easily enable networking and wireless on your system. Remember to always check the documentation for your specific system, as the commands may vary. If you’re interested in learning more about the command line, this guide is a great place to start.
