② kali linux支持我的AR9258网卡，但进CDlinux却网卡灯不亮，

CDLinux可能不支持AR9258网卡，需要手动安装网卡驱动。以下是可能的原因及解决方案：

1. 驱动兼容性问题：

   • 原因：CDLinux可能并没有自带AR9258网卡的驱动。由于网卡驱动可能是nonfree的，CDLinux默认可能不包含这些闭源驱动。
   • 解决方案：你需要访问CDLinux的官方网站或相关社区论坛，查找是否有适用于AR9258网卡的驱动，并按照提供的指南进行下载和安装。

2. 网卡硬件支持：

   • 原因：虽然Kali Linux支持AR9258网卡，但不同的Linux发行版可能对硬件的支持有所不同。CDLinux可能并未针对AR9258网卡进行充分的测试和优化。
   • 解决方案：在CDLinux的社区或官方论坛上寻求帮助，了解是否有其他用户遇到并解决了类似的问题。同时，你也可以考虑使用其他Linux发行版或更新CDLinux到最新版本，看看问题是否得到解决。

3. 网卡灯不亮的问题：

   • 可能原因：网卡灯不亮可能是由于硬件故障、驱动问题或系统配置错误导致的。在确认驱动兼容性和硬件支持后，还需要检查系统配置和硬件连接。
   • 解决方案：首先，确保网卡已正确连接到主板和电源。其次，检查CDLinux的系统日志，看是否有与网卡相关的错误信息。如果问题依旧存在，可能需要考虑更换网卡或寻求专业的技术支持。

总结：CDLinux可能由于驱动兼容性问题而不支持AR9258网卡。你需要手动下载并安装适用于该网卡的驱动，或者考虑使用其他Linux发行版。同时，也需要检查网卡硬件和系统配置，确保一切连接正确无误。

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
=======

kernel with a supported adapter, email the specific information related to
the issue to [email protected]
