1.使用wget下载wireless包和补丁并校验md5

wget https://hewlettpackard.github.io/wireless-tools/wireless_tools.29.tar.gz

wget  http://www.linuxfromscratch.org/patches/blfs/8.3/wireless_tools-29-fix_iwlist_scanning-1.patch
md5sum -c md5sums

2.解压wireless包并进入包目录

tar -xvf wireless_tools..tar.gz

cd wireless_tools.

3.参照书中说明编译安装

patch -Np1 -i ../wireless_tools--fix_iwlist_scanning-.patch

make -j8

make PREFIX=/usr INSTALL_MAN=/usr/share/man install

4.返回blfs-sources目录并删除解压的包目录

cd $LFS/sources/blfs-sources

rm -rf wireless_tools

5.下载wpa包的依赖libnl包和补丁包并验证md5

wget http://mirror.fileplanet.com/lfs/pub/blfs/8.3/l/libnl-3.4.0.tar.gz

wget http://mirror.fileplanet.com/lfs/pub/blfs/8.3/l/libnl-doc-3.4.0.tar.gz

md5sum -c md5sums

6.解压并进入libnl包目录

tar -xvf libnl-3.4..tar.gz

cd libnl-3.4.

7.参照书中内容编译安装

./configure --prefix=/usr     \
--sysconfdir=/etc \
--disable-static &&
make -j8 make -j8 check make install mkdir -vp /usr/share/doc/libnl-3.4. &&
tar -xf ../libnl-doc-3.4..tar.gz --strip-components= --no-same-owner \
-C /usr/share/doc/libnl-3.4.

8.返回blfs-sources目录并删除解压的包目录

cd $LFS/sources/blfs-sources

rm -rf libnl-3.4.

9.下载pciutils并校验md5

wget https://mirrors.edge.kernel.org/pub/software/utils/pciutils/pciutils-3.6.2.tar.xz

md5sum  -c md5sums

10.解压并进入pciutils包目录

tar -xvf pciutils-3.6..tar.xz

cd pciutils-3.6.

11.参照书中说明编译安装

make PREFIX=/usr                \
SHAREDIR=/usr/share/hwdata \
SHARED=yes make PREFIX=/usr \
SHAREDIR=/usr/share/hwdata \
SHARED=yes \
install install-lib && chmod -v /usr/lib/libpci.so

12.返回blfs-sources目录并删除解压的包目录

cd $LFS/sources/blfs-sources

rm -rf pciutils-3.6.2

13.运行命令查看无线网络设备硬件的名字

lspci

14.解压在编译lfs过程中用过的linux内核包,进入linux内核包按照lfs的linux内核编译方法编译内核添加以下配置

[*] Networking support  --->                              [CONFIG_NET]
[*] Wireless ---> [CONFIG_WIRELESS]
<*/M> cfg80211 - wireless configuration API [CONFIG_CFG80211]
[*] cfg80211 wireless extensions compatibility [CONFIG_CFG80211_WEXT]
<*/M> Generic IEEE 802.11 Networking Stack (mac80211) [CONFIG_MAC80211]
Device Drivers --->
[*] Network device support ---> [CONFIG_NETDEVICES]
[*] Wireless LAN ---> [CONFIG_WLAN]
<*/M>一定要在所选择的项目上面打上m
我的机器是intel7625的无线网卡设备,wireless LAN下没有这个型号,查询其它linux发行版给无线网卡加载的是哪个模块,所以选择了iwlwifi的两个模块

15.去lfs的固件网站下载所对应的iwlwifi-7265D-22到29区间的固件到/lib/firmware/目录下

cd /lib/firmware/

wget http://anduin.linuxfromscratch.org/BLFS/linux-firmware/iwlwifi-7265D-29.ucode

16.下载wpa包和补丁并校验md5

wget https://w1.fi/releases/wpa_supplicant-2.6.tar.gz

wget http://www.linuxfromscratch.org/patches/blfs/8.3/wpa_supplicant-2.6-upstream_fixes-2.patch

md5sum  -c md5sums

17.解压并进入wpa包目录

tar -xvf wpa_supplicant-2.6.tar.gz

cd wpa_supplicant-2.6

18.参照书中内容编译安装

cat > wpa_supplicant/.config << "EOF"
CONFIG_BACKEND=file
CONFIG_CTRL_IFACE=y
CONFIG_DEBUG_FILE=y
CONFIG_DEBUG_SYSLOG=y
CONFIG_DEBUG_SYSLOG_FACILITY=LOG_DAEMON

cd wpa_supplicant &&
make BINDIR=/sbin LIBDIR=/lib
install -v -m755 wpa_{cli,passphrase,supplicant} /sbin/ &&
install -v -m644 doc/docbook/wpa_supplicant.conf. /usr/share/man/man5/ &&
install -v -m644 doc/docbook/wpa_{cli,passphrase,supplicant}. /usr/share/man/man8/

19.返回blfs-sources目录并删除解压的包目录

cd $LFS/sources/blfs-sources

rm -rf wpa_supplicant-2.6

20.设置wpa

wpa_passphrase SSID SECRET_PASSWORD > /etc/sysconfig/wpa_supplicant-wifi0.conf

wifi0替换为pci查到的无线网络设备名字

21.则在/etc/wpa_supplicant/wpa_supplicant-wifi0.conf文件中加入以下参数

ctrl_interface=DIR=/run/wpa_supplicant GROUP=root
update_config=1

22.安装wpa的blfs脚本包

make install-service-wpa

23.配置dhcpcd


cat > /etc/sysconfig/ifconfig.wifi0 << "EOF"
ONBOOT="yes"
IFACE="wlan0"
SERVICE="wpa" # Additional arguments to wpa_supplicant
WPA_ARGS="" WPA_SERVICE="dhcpcd"
DHCP_START="-b -q <insert appropriate start options here>"
DHCP_STOP="-k <insert additional stop options here>"

EOF
wlan0和wifi0替换为lspci查到的无线设备的名字

24.使用wps_cli工具链接无线网络的方法

 1.进入wpa_cli工具下
wpa_cli

2.添加一个网络连接

add_network

默认id为0

3.扫描并显示结果

scan
scan_result

4.设置网络id:0的接入点与连接秘钥

set_network 0 ssid “<填入网络名字>”
set_network 0 psk "<填入网络密码>"

5.使用配置网络或连接配置网络id 0

enable_network 0 

select_network 0
