Network management in Ubuntu

Network management in Ubuntu is a process of organizing and controlling the use of computer networks in a corporate environment. It includes the process of planning, designing, implementing, monitoring, and maintaining the network infrastructure.

Network management on Ubuntu can be done through various methods, including command-line utilities and graphical user interfaces. Here are some options:

NetworkManager: NetworkManager is the default network management service on Ubuntu. It provides a graphical user interface for managing network connections, such as wired, wireless, VPN, and mobile broadband. You can access the NetworkManager GUI by clicking on the network icon in the top right corner of the screen. From there, you can view available networks, connect to a network, and configure network settings.

nmcli: nmcli is a command-line tool that is part of the NetworkManager package. It allows you to manage network connections from the terminal. You can use nmcli to view the status of network connections, configure network settings, and activate/deactivate network connections.

ifconfig: ifconfig is a command-line tool that allows you to configure and view network interfaces. You can use ifconfig to view the IP address, netmask, and other network settings for a specific interface. However, ifconfig is not installed by default on newer versions of Ubuntu and has been replaced by the ip command.

ip: ip is a command-line tool that allows you to manage network interfaces and routing tables. You can use ip to view network settings, configure interfaces, and troubleshoot network connectivity issues.

Overall, NetworkManager and nmcli are the most commonly used tools for network management on Ubuntu. They are user-friendly and offer a wide range of features to manage network connections.
