Check Linux Server Network Card Guide

There are several common methods to check the hardware network card of a server in a Linux system.

1. Using the ifconfig command: Typing the ifconfig command in the terminal will display all the network interfaces on the current server along with their respective information, including hardware address, IP address, subnet mask, and more.
2. To utilize the ip command: inputting the ip addr command in the terminal will display all network interfaces and their information on the current server, such as hardware address, IP address, subnet mask, etc.
3. To inspect the /sys/class/net directory, input the command ls /sys/class/net in the terminal. This directory contains symbolic links to all network interfaces, allowing you to gather information about the network interfaces by examining these links.
4. Use the lshw command: to display detailed information about all network interfaces on the current server, including hardware models and drivers, type “lshw -class network” in the terminal.

Using the methods above, you can view the information of the server’s hardware network card to understand the server’s network configuration.
