This article mainly explains "how to install and configure network equipment in Linux system". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "How to install and configure network devices in Linux system"!

I. Install and configure network equipment

When installing linux, if you have a network card, the installer will prompt you for tcp/ip network configuration parameters, such as the ip address of the local machine, the ip address of the default gateway, the ip address of the DNS, etc. Based on these configuration parameters, the installer will automatically compile the network card (linux system first to support) driver into the kernel. But we must understand the process of loading the network card driver, then in the future change the network card, when using multiple network cards we will be very easy to operate. The requested URL/lib/modules/was not found on this server.(linux version number)/net/ , for example, inter 82559 series 10/100M adaptive boot network card driver is eepro100.o, 3COM 3C509 ISA network card driver is 3C509.o, DLINK pci 10 network card driver is via-rhine.o, NE2000 compatibility network card drivers are ne2k-pci.o and ne.o. After understanding these basic drivers, we can change the module configuration file to replace the network card or add network cards.

1. Modify the/etc/conf.modules file

This configuration file is an important parameter file for loading modules. Let's look at an example file first.

#/etc/conf.modules

alias eth0 eepro100

alias eth2 eepro100

this file is the contents of conf.modules in linux system with two inter 82559 series network cards installed.alias command indicates the name of the driver for ethernet port (such as eth0),alias eth0 eepro100 indicates that the driver to be loaded on ethernet port zero is eepro 100.o. then when using modprobe eth0 command, the system will automatically load eepro 100.o into the kernel. for pci network cards, since the system will automatically find the io address and interrupt number of the network card, there is no need to use options in conf.modules to specify the io address and interrupt number of the network card. However, for ISA cards, you must specify the IO address or interrupt number of the hardware in the conf.modules file, as shown below, indicating a NE ISA card conf.modules file.

alias eth0 ne

options ne io=0x300 irq=5

After modifying the conf.modules file, you can load the module using the command, e.g. the second NIC to insert inter:

#insmod /lib/modules/2.2.14/net/eepro100.o

In this way, you can load the module eepro100.o. on the Ethernet port. At the same time, you can also use the command to view the currently loaded module information:

[root@ice /etc]# lsmod

Module Size Used by

eepro100 15652 2 (autoclean)

The meaning of the returned result is that the currently loaded module is eepro100, the size is 15652 bytes, the user is two, and the mode is automatically cleared.

At this point, I believe that everyone has a deeper understanding of "how to install and configure network equipment in Linux system," so let's actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
