② kali linux支持我的AR9258網卡，但進CDlinux卻網卡燈不亮，

CDLinux可能不支持AR9258網卡，需要手動安裝網卡驅動。以下是可能的原因及解決方案：

1. 驅動兼容性問題：

   • 原因：CDLinux可能並沒有自帶AR9258網卡的驅動。由於網卡驅動可能是nonfree的，CDLinux默認可能不包含這些閉源驅動。
   • 解決方案：你需要訪問CDLinux的官方網站或相關社區論壇，查找是否有適用於AR9258網卡的驅動，並按照提供的指南進行下載和安裝。

2. 網卡硬體支持：

   • 原因：雖然Kali Linux支持AR9258網卡，但不同的Linux發行版可能對硬體的支持有所不同。CDLinux可能並未針對AR9258網卡進行充分的測試和優化。
   • 解決方案：在CDLinux的社區或官方論壇上尋求幫助，了解是否有其他用戶遇到並解決了類似的問題。同時，你也可以考慮使用其他Linux發行版或更新CDLinux到最新版本，看看問題是否得到解決。

3. 網卡燈不亮的問題：

   • 可能原因：網卡燈不亮可能是由於硬體故障、驅動問題或系統配置錯誤導致的。在確認驅動兼容性和硬體支持後，還需要檢查系統配置和硬體連接。
   • 解決方案：首先，確保網卡已正確連接到主板和電源。其次，檢查CDLinux的系統日誌，看是否有與網卡相關的錯誤信息。如果問題依舊存在，可能需要考慮更換網卡或尋求專業的技術支持。

總結：CDLinux可能由於驅動兼容性問題而不支持AR9258網卡。你需要手動下載並安裝適用於該網卡的驅動，或者考慮使用其他Linux發行版。同時，也需要檢查網卡硬體和系統配置，確保一切連接正確無誤。

③ 在LINUX中如何載入驅動網卡

直接找好對應的驅動 一般都會有readme 或者install 之類的說明文檔來告訴你如何去安裝這個網卡驅動的

Linux* Base Driver for the Atheros(R) AR8121/AR8113 PCI-E Ethernet Adapter
==========================================================================

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 mole 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
<filename.tar.gz>'. Replace <filename.tar.gz> 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/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 mole:

make install

The binary will be installed as:

/lib/moles/<KERNEL VERSION>/kernel/drivers/net/arl1e.[k]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 mole:

insmod arl1e <parameter>=<value>

6. Assign an IP address to the interface by entering the following, where
x is the interface number:

ifconfig ethx <IP_address>

7. Verify that the interface works. Enter the following, where <IP_address>
is the IP address for another machine on the same subnet as the interface
that is being tested:

ping <IP_address>

Command Line Parameters
=======================

If the driver is built as a mole, the following optional parameters are
used by entering them on the command line with the modprobe or insmod command
using this syntax:

modprobe arl1e [<option>=<VAL1>,<VAL2>,...]

insmod arl1e [<option>=<VAL1>,<VAL2>,...]

For example, with two L001 PCIE adapters, entering:

insmod 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
0 - auto-negotiate at all supported speeds
1 - only link at 1000Mbps Full Duplex
2 - only link at 100Mbps Full Duplex
3 - only link at 100Mbps Half Duplex
4 - only link at 10Mbps Full Duplex
5 - only link at 10Mbps Half Duplex
Default Value: 0
media_type forces the line speed/plex 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: 50-65000
Default Value: 100
This value represents the minmum interval between interrupts controller
generated.

RxMemBlock
Valid Range: 16-512
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 transmit memory allocated by the driver.
Increasing this value allows the driver to queue more transmits.

NOTE: Depending on the available system resources, the request for a
higher number of transmit 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/moles.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 ring this process you are asked for the driver or mole
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 plex to 10full and 100half, add the
following to moles.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:

http://support.atheros.com

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 [email protected]
