让RTL8187无线网卡在linux 2.6.28内核支持aircrack-ng注入。

本文使用Gentoo Linux，内核已升级到目前最新版本号如下

crob@crob ~ $ uname -a
Linux crob 2.6.28-gentoo #34 SMP Wed Jan 14 17:00:22 CST 2009 i686 Intel(R) Core(TM)2 Duo CPU T5470 @ 1.60GHz GenuineIntel GNU/Linux

一、配置内核，选中内核中对rtl8187的支持，编译成模块

Device Drivers --->

Network device support --->

Wireless LAN --->

[*] Wireless LAN (IEEE 802.11)

<M> Realtek 8187 and 8187B USB support

二、下载内核补丁，使rtl8187支持injection（注入模式）

wget  http://astray.fragstore.net/apps/mac80211_2.6.28-rc8-wl_frag+ack_radiotap_2.6.28_mod.patch wget http://astray.fragstore.net/apps/rtl8187-mac80211-pwr.patch 
1、将以上两文件复制到内核源代码目录（一般是/usr/src/linux）
2、执行以下命令，检查补丁是否有问题
patch -Np1 --dry-run -i rtl8187-mac80211-injection-speed-2.6.28-rc6.patch
patch -Np1 --dry-run -i rtl8187-mac80211-pwr.patch
3、如果第2步无错误则将--dry-run去掉后，再次执行
4、重新编译、安装内核模块
make clean && make && make modules_install
copy arch/i386/boot/bzImage  /boot/内核文件名
5、重启
注：如果是2.6.28以前版本的内核可能还需要打上以下补丁，步骤相同（附录1的贴子里老外说2.6.28内核不用打这个补丁了）
wget http://trac.aircrack-ng.org/export/1330/trunk/patches/rtl8187-mac80211-injection-speed-2.6.28-rc6.patch：

OK！现在你的RTL8187可以支持注入，aircrack-ng no problems !

Kernel 2.6.28 update patched for EXT4 CD upgrade.

Well, as a sidenote: generally the patches for mac80211 used in my
tutorial are generic 2.6.28 fragmentation/ack patches, so they could be
used for this 2.6.28 update CD. The only true ALFA related patches are
rtl8187-mac80211-injection-speed-2.6.28-rc6.patch and
rtl8187-mac80211-pwr.patch, which aren't NECESSARY, but useful.
