Linux网络设置:如何正确加载网卡驱动程序? (linux加载网卡)

作为一名Linux系统管理员,网络设置是一项非常重要的工作。在Linux系统中,网卡驱动程序是连接计算机与网络的重要组成部分。在安装Linux系统以后,网络设置极有可能会出现问题,而网卡驱动程序是其中的一个主要原因。本文将重点介绍正确加载网卡驱动程序的方法。

之一步:确认网卡型号

在开始前,首先我们需要确定计算机中的网卡型号。在Linux中,有很多工具可以帮助我们找到这些信息。其中最常用的是lspci命令,它可以列出系统中所有的PCI总线信息。通过使用lspci命令,我们可以找到服务器中的网卡型号。

例如,我们可以使用以下命令列出系统中的PCI总线信息:

“`

# lspci | grep Ethernet

“`

该命令将会输出计算机中所有的以太网接口信息,包括供应商ID、设备ID以及具体的网卡型号。

第二步:下载网卡驱动程序

一旦我们确认了网卡型号,我们需要根据网卡型号下载相应的网卡驱动程序。网卡驱动程序可以从供应商网站上下载,也可以从Linux内核源码中找到。

如果我们下载的是源代码,则需要编译安装。在编译安装之前,我们需要安装Linux内核源码包以及编译环境。这些工具可以通过工具包管理系统(例如yum和apt-get)来安装。Ubuntu用户可以使用以下命令安装所需的工具:

“`

# apt-get install linux-source build-essential

“`

CentOS用户可以使用以下命令安装所需的工具:

“`

# yum install kernel-devel gcc

“`

在安装完必要的工具之后,我们需要下载所需的驱动程序,并解压压缩包。然后,我们需要进入解压后的驱动程序目录,并运行以下命令:

“`

# make

# make install

“`

这些命令将会编译驱动程序,并将其安装到Linux系统中。

如果我们下载的是已经编译好的驱动程序,那么我们可以直接将其拷贝到系统中。在拷贝完成后,我们需要运行以下命令加载驱动程序:

“`

# inod /path/to/driver.ko

“`

这些命令将会加载我们的网络驱动程序。

第三步:配置网卡

在加载完网卡驱动程序后,我们需要对网卡进行配置。我们可以通过修改/etc/network/interfaces文件来配置网卡。以下是一个样例配置文件:

“`

auto eth0

iface eth0 inet static

address 192.168.1.10

netmask 255.255.255.0

gateway 192.168.1.1

“`

在这个例子中,我们使用静态IP地址配置eth0接口。我们指定了接口的IP地址、子网掩码和网关。在配置完成后,我们需要运行以下命令来使配置生效:

“`

# ifup eth0

“`

这些命令将会激活eth0接口并应用我们的新配置。如果出现任何问题,我们可以使用以下命令来检查接口连接情况:

“`

# ifconfig eth0

“`

这些命令将会显示当前eth0接口的状态信息。

结论

在本文中,我们介绍了如何正确加载和配置Linux系统中的网卡驱动程序。在正确地加载和配置网卡驱动程序后,我们就可以为Linux系统提供网络连接。网络设置是Linux系统维护中的重要一环,希望通过这篇文章的介绍,读者可以更好地理解和掌握Linux系统中的网络设置。

– Building and Installation

– Command Line Parameters

– Additional Configurations

– Known Issues

– Support

In This Release

===============

This file describes the Linux* Base Driver for the Atheros(R) AR8121/AR8113 PCI-E

Ethernet Adapter, version 1.0.0.5 This driver supports the 2.4.x and 2.6.x kernels.

This driver is only supported as a loadable module at this time. Atheros is not

supplying patches against the kernel source to allow for static linking of

the driver. For questions related to hardware requirements, refer to the

documentation supplied with your Atheros(R) adapter. All hardware

requirements listed apply to use with Linux.

Building and Installation

=========================

To build a binary RPM* package of this driver, run ‘rpmbuild -tb

‘. Replace with the specific filename of

the driver.

NOTE: For the build to work properly, the currently running kernel MUST match

the version and configuration of the installed kernel sources. If you

have just recompiled the kernel reboot the system now.

RPM functionality has only been tested in Red Hat distributions.

1. Move the base driver tar file to the directory of your choice. For example,

use /home/username/arl1e or /usr/local/src/枣唯arl1e.

2. Untar/unzip archive:

tar zxf arl1e-x.x.x.x.tar.gz

3. Change to the driver src directory:

cd arl1e-x.x.x.x/src/

4. Compile the driver module:

make install

The binary will be installed as:

/lib/modules//kernel/drivers/net/arl1e.o

The install locations listed above are the default locations. They might

not be correct for certain Linux distributions. For more information,

see the ldistrib.txt file included in the driver tar.

5. Install the module:

inod arl1e =

6. Assign an IP address to the interface by entering the following, where

x is the interface number:

ifconfig ethx

7. Verify that the interface works. Enter the following, where

is the IP address for another machine on the same subnet as the interface

that is being tested:

ping

Command Line Parameters

=======================

If the driver is built as a module, the following optional parameters are

used by entering them on the command line with the modprobe or inod command

using this syntax:

modprobe arl1e

inod arl1e

For example, with two L001 PCIE adapters, entering:

inod arl1e TxMemSize=80,128

loads the arl1e driver with 8KB TX memory for the first adapter and 10KB TX memory

for the second adapter.

The default value for each parameter is generally the recommended setting,

unless otherwise noted.

NOTES: A descriptor describes a data buffer and attributes related to the

data buffer. This information is accessed by the hardware.

media_type

Valid Range: 0-4

auto-negotiate at all supported speeds

only link at 1000Mbps Full Duplex

only link at 100Mbps Full Duplex

only link at 100Mbps Half Duplex

only link at 10Mbps Full Duplex

only link at 10Mbps Half Duplex

Default Value: 0

media_type forces the line speed/duplex to the specified value in

megabits per second(Mbps). If this parameter is not specified or is set

to 0 and the link partner is set to auto-negotiate, the board will

auto-detect the correct speed.

int_mod_timer

Valid Range:

Default Value: 100

This value represents the minmum interval between interrupts controller

generated.

RxMemBlock

Valid Range:

Default Value: 64

This value is the number of receice memory block allocated by the driver.

Increasing this value allows the driver to buffer more incoming packets.

Each memory block is 1536 bytes.

NOTE: Depending on the available system resources, the request for a

higher number of receive descriptors may be denied. In this case,

use a lower number.

TxMemSize

Valid Range: 4-64

Default Value: 8

This value is the number KB of tranit memory allocated by the driver.

Increasing this value allows the driver to queue more tranits.

NOTE: Depending on the available system resources, the request for a

higher number of tranit descriptors may be denied. In this case,

use a lower number.

FlashVendor

Valid Range: 0-2

Default Value: 0

This value standards on vendor of spi flash used by the adapter.

0 for Atmel, 1 for SST, 2 for ST

Additional Configurations

=========================

Configuring the Driver on Different Distributions

Configuring a network driver to load properly when the system is started is

distribution dependent. Typically, the configuration process involves adding

an alias line to /etc/modules.conf as well as editing other system startup

scripts and/or configuration files. Many popular Linux distributions ship

with tools to make these changes for you. To learn the proper way to

configure a network device for your system, refer to your distribution

documentation. If during this process you are asked for the driver or module

name, the name for the Linux Base Driver for the Atheros AR8121/AR8113 is arl1e

As an example, if you install the arl1e driver for two AR8121/AR8113 adapters

(eth0 and eth1) and set the speed and duplex to 10full and 100half, add the

following to modules.conf:

alias eth0 arl1e

alias eth1 arl1e

options arl1e Speed=10,100 Duplex=2,1

Viewing Link Messages

Link messages will not be displayed to the console if the distribution is

restricting system messages. In order to see network driver link messages

on your console, set dmesg to eight by entering the following:

dmesg -n 8

NOTE: This setting is not saved across reboots.

Known Issues

============

NOTE: For distribution-specific information, see the ldistrib.txt file

included in the driver tar.

Driver Compilation

——

When trying to compile the driver by running make install, the following

error may occur:

“Linux kernel source not configured – missing version.h”

To solve this issue, create the version.h file by going to the Linux source

tree and entering:

make include/linux/version.h.

Support

=======

For general information, go to the Atheros support website at:

If an issue is identified with the released source code on the supported

kernel with a supported adapter, email the specific information related to

the issue to
