How to set up and connect the network on Kirin operating system?

Abstract:
Kirin operating system is a domestic operating system based on Linux and is widely used in Chinese government agencies, enterprises and institutions. Network connection is one of the basic functions of Kirin operating system. This article will introduce how to set up and connect the network in Kirin operating system, with code examples.

1. Network settings
In the Kirin operating system, network settings can be performed through the graphical interface or the command line. The following is a detailed introduction in command line mode.

1. Open Terminal
   In Kirin operating system, we can open the terminal by pressing the Ctrl Alt T key combination or clicking the terminal icon on the application bar.

2. View network interface
   Use the ifconfig command to view the network interface status on the current system. Enter the following command in the terminal:

   ifconfig

   This command will display a list of all network interfaces, including interface names, IP addresses, MAC addresses, etc.

3. Configuring the network interface
   Use the ifconfig command to configure the IP address, subnet mask and other parameters of the network interface. Enter the following command in the terminal:

   sudo ifconfig <interface_name> <ip_address> netmask <subnet_mask>

   Among them, is the name of the network interface, is the IP address to be configured, is the subnet mask. For example, if you want to set the IP address of the eth0 interface to 192.168.1.100 and the subnet mask to 255.255.255.0, you can enter the following command:

   sudo ifconfig eth0 192.168.1.100 netmask 255.255.255.0

   After the configuration is successful, you can use the ifconfig command to view the network interface again. configuration.

4. Set the default gateway
   Use the route command to set the default gateway. Enter the following command in the terminal:

   sudo route add default gw <gateway_ip>

   where is the IP address of the default gateway. For example, if the IP address of the default gateway is 192.168.1.1, you can enter the following command:

   sudo route add default gw 192.168.1.1

   After the setting is successful, the system can connect to the network through the default gateway.

2. Network connection
Kirin operating system supports a variety of network connection methods, including wired connections and wireless connections. The following takes the wired connection method as an example for detailed introduction.

1. Open Network Manager
   Kylin operating system uses NetworkManager as a network management tool. Enter the following command in the terminal to open the network manager:

   nm-connection-editor

   Or click the "Network" option in the system settings to enter the network manager.

2. Create a wired connection
   In the Network Manager, click the "Add" button to create a new connection. Select "Wired Connection" and click the "Create" button.
3. Configuring wired connection
   In the pop-up configuration interface, select the correct network device, such as eth0. Select "Automatic (DHCP)" in IPv4 settings or configure the IP address manually. After completing the configuration, click "Save".
4. Connect to the network
   In the network manager, find the wired connection you just created and click the "Connect" button to connect to the network.

Code example:
The following is a sample code using Python script for network configuration:

import subprocess

# 设置IP地址和子网掩码
ip_address = "192.168.1.100"
subnet_mask = "255.255.255.0"

# 配置网络接口
subprocess.run(["sudo", "ifconfig", "eth0", ip_address, "netmask", subnet_mask])

# 设置默认网关
gateway_ip = "192.168.1.1"
subprocess.run(["sudo", "route", "add", "default", "gw", gateway_ip])

The above code uses the subprocess module to call system commands for network configuration, which can be found in Execute this script in the terminal to set up the network.

Conclusion:
This article introduces how to set up and connect the network in Kirin operating system. Through the command line, we can configure the network interface, set the default gateway, and implement basic network connections. At the same time, through the graphical interface provided by NetworkManager, we can easily create and manage various types of network connections. I hope this article can help readers better understand and use the network functions of Kirin Operating System.
