Configure Network Settings in Ubuntu 18.04
Configuring network settings in Ubuntu 18.04 can be done using the `nmcli` command-line tool. Here are the basic steps to follow:
- Open a terminal and type `sudo nm-connection-editor` to open the Network Connections editor.
- Select the wired or wireless connection you want to configure.
- Click on the "Edit" button to edit the connection settings.
- Configure the settings, such as IP address, netmask, gateway, and DNS servers.
- Save the changes.
Alternatively, you can use the `ip` command-line tool to configure network settings. For example, to set the IP address, netmask, and gateway of a network interface, you can use the following command: `sudo ip addr add 192.168.1.100/24 dev eth0` to set the IP address, `sudo ip link set dev eth0 down` to set the netmask, and `sudo ip link set dev eth0 up` to set the gateway.
