How to configure Network in Kali Linux
1. On the Desktop with NetworkManager: In Kali Linux, the NetworkManager is already installed and can be configured through GNOME's control center or through the top-right menu on Desktop as shown in Figure below.
2. On the Command-line with "ifupdown" command: When we want to configure the network settings without using the graphical desktop, we can use the command-line with the already-installed package i.e., ifupdown. It has Ifup and Ifdown tool. The network device can be removed at any time with the ifdown network device. And can modify and back up the network using the ifup network device.
And for wireless interfaces, we need the wpasupplicant package, which is included in Kali by default. The most commonly used options are WPA-SSID (defines the name of the wireless network to join) and WPA-PSK (defines the key protecting the network).
Note: You must provide more details such as IP address, the network, and the IP of the gateway for the fixed IP address configuration.
3. On the Command-line with "systemd-networkd" command: The ifupdown approach is a legacy tool used by Debian but still used as the default for server and other minimal installations. The new tool is introduced in the Kali for Network Configuration, which is systemd-networkd. It's integration with the init system makes it an attractive choice. You can configure these by placing the network files into the /etc/systemd/network/directory.
