本文使用的linux发行版本Ubuntu 20.04.6 LTS
1 编译wpa_supplicant软件
1.1 下载wpa_supplicant
wpa_supplicant各版本下载页面Index of /releases
在页面中不同前缀开头的表示不同的程序后面的数字代表版本号
- Prism2 - hostap - hostap-driver - hostap-utils - hostapd - wpa_supplican - wpa_supplicant-cygwin-bin - wpa_supplicant-windows-bin
只需下载wpa_supplican前缀的包即可在Linux系统中下载命令如下
mkdir -p ~/Documents
cd ~/Documents
wget https://w1.fi/releases/wpa_supplicant-2.10.tar.gz
tar -xzvf wpa_supplicant-2.10.tar.gz
cd wpa_supplicant-2.10
进入wpa_supplicant-2.10文件夹查看wpa_supplicant/README
vim wpa_supplicant/README
搜索关键字www.openssl可以看到如下内容
Optional libraries for EAP-TLS, EAP-PEAP, and EAP-TTLS:- OpenSSL (tested with 1.0.1 and 1.0.2 versions; assumed towork with most relatively recent versions; this is likely to beavailable with most distributions, http://www.openssl.org/)
- GnuTLS
- internal TLSv1 implementation
说明该wpa_supplicant版本依赖openssl 1.0.1或1.0.2版本
1.2 下载openssl
OpenSSL是一个开源的密码学库和SSL/TLS协议实现下载页面[ Downloads ] - /source/index.html
1.0.1是较老的版本下载页面[ 1.0.1 ] - /source/old/1.0.1/index.html
只需下载第一个链接即可在Linux系统中下载命令如下
cd ~/Documents
wget https://www.openssl.org/source/old/1.0.1/openssl-1.0.1u.tar.gz
tar -zxvf openssl-1.0.1u.tar.gz
cd openssl-1.0.1u 1.3 编译安装openssl
进入openssl-1.0.1u文件夹执行以下命令安装openssl
注意./config --openssldir/usr/local/bin/openssl-1.0.1u shared命令中指定了openssl的安装路径
cd ~/Documents
cd openssl-1.0.1u
./config --openssldir/usr/local/bin/openssl-1.0.1u shared
sudo make
sudo make install
ls -l /usr/bin/openssl
openssl version -a
sudo mv /usr/bin/openssl /usr/bin/openssl_oldsudo ln -s /usr/local/bin/openssl-1.0.1u/bin/openssl /usr/bin/openssl
ls -l /usr/bin/openssl
openssl_old version -a
openssl version -a
系统本身已经安装过openssl所以将已安装的openssl软链接改为openssl_old再创建了一个新的openssl软链接
最后输出结果如下
OpenSSL 1.0.1u 22 Sep 2016

OPENSSLDIR: /usr/local/bin/openssl-1.0.1u
1.4 安装libnl、libssl和libdbus
安装wpa_supplicant还需要libnl、libssl和libdbus库的支持
sudo apt-get update
sudo apt-get install libdbus-1-dev
sudo apt-get install libssl-dev
sudo apt-get install libnl-3-dev libnl-3-200 libnl-genl-3-dev libnl-route-3-dev
注意上述命令中的几个libnl包只要有一个能安装成功即可测试libnl-genl-3-dev在Ubuntu 20.04.6 LTS上可以正常安装
安装成功后使用命令查看libnl包
sudo apt list libnl*
结果如下
ibnl-3-200-dbg
libnl-3-200
libnl-3-dev
libnl-cli-3-200
libnl-cli-3-dev
libnl-genl-3-200
libnl-genl-3-dev
libnl-idiag-3-200
libnl-idiag-3-dev
libnl-nf-3-200
libnl-nf-3-dev
libnl-route-3-200
libnl-route-3-dev
libnl-utils
libnl-xfrm-3-200
libnl-xfrm-3-dev
libnlopt-cxx-dev
libnlopt-cxx0
libnlopt-dev
libnlopt-guile0
libnlopt0
对照以上包缺少哪一个就再安装那一个包 1.5 编译安装wpa_supplicant
最后编译并安装wpa_supplicant执行以下命令
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
cp defconfig .config
ls -l .config
sudo ln -s /usr/local/bin/openssl-1.0.1u/lib/libcrypto.so /usr/lib/libcrypto.so
sudo make
sudo make install
wpa_supplicant -v
最后输出结果如下
wpa_supplicant v2.10
Copyright (c) 2003-2022, Jouni Malinen jw1.fi and contributors 1.6 编译结果
在wpa_supplicant文件下可以看到编译后的可执行文件
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
file * | grep ELF
结果如下
wpa_cli: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]1ecc67063a6d45d7432f9d946a7ae3f2642cb47d, for GNU/Linux 3.2.0, with debug_info, not stripped

wpa_supplicant: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]49e7bf7c341bc72ceac844ef90f5ba3ad30fefd1, for GNU/Linux 3.2.0, with debug_info, not stripped编译结果中有3个软件wpa_supplicant、wpa_cli、wpa_passphrase
1、wpa_passphrase用于向conf配置文件中添加网络配置信息例如 sudo wpa_passphrase ssid passphrase | sudo tee wpa_supplicant.conf 2、wpa_supplicant用于启动wpa_supplicant应用程序例如 sudo wpa_supplicant -D nl80211 -i wlan0 -c wpa_supplicant.conf 3、wpa_cli用于与 wpa_supplicant控制接口进行交互的命令行工具例如 输入wpa_cli -i wlan0 scan命令用于扫描 输入wpa_cli -i wlan0 scan_results查看扫描结果
安装之前使用命令whereis wpa_cli wpa_supplicant wpa_passphrase查看位置如下
wpa_cli: /usr/sbin/wpa_cli /usr/share/man/man8/wpa_cli.8.gz
wpa_supplicant: /usr/sbin/wpa_supplicant /etc/wpa_supplicant /usr/share/man/man8/wpa_supplicant.8.gz
wpa_passphrase: /usr/bin/wpa_passphrase /usr/share/man/man8/wpa_passphrase.8.gz
安装之后使用命令whereis wpa_cli wpa_supplicant wpa_passphrase查看位置如下
wpa_cli: /usr/sbin/wpa_cli /usr/local/sbin/wpa_cli /usr/share/man/man8/wpa_cli.8.gz
wpa_supplicant: /usr/sbin/wpa_supplicant /etc/wpa_supplicant /usr/local/sbin/wpa_supplicant /usr/share/man/man8/wpa_supplicant.8.gz
wpa_passphrase: /usr/bin/wpa_passphrase /usr/local/sbin/wpa_passphrase /usr/share/man/man8/wpa_passphrase.8.gz
说明本次编译这3个软件安装的位置在/usr/local/sbin具体路径如下
wpa_cli: /usr/local/sbin/wpa_cli
wpa_supplicant: /usr/local/sbin/wpa_supplicant
wpa_passphrase: /usr/local/sbin/wpa_passphrase 2 运行wpa_supplicant 2.1 编辑wpa_supplicant.conf文件
在运行wpa_supplicant时需要先设置conf文件
关于conf文件中各参数配置的详细解释可以查看wpa_supplicant-2.10/wpa_supplicant/wpa_supplicant.conf文件
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
vim wpa_supplicant.conf
新建wpa_supplicant.conf文件如下
sudo vim /etc/wpa_supplicant/wpa_supplicant.conf
在文件中输入以下内容
ctrl_interface/var/run/wpa_supplicant
update_config1
countryCN
ap_scan1network{ssidxxxxxxpskpassword
}
然后插入一个免驱的usb无线网卡虽然免驱其实是Linux系统已经自带了该类型网卡的驱动
插入网卡生效后输入ifconfig查看网卡信息结果如下
wlan0: flags4099UP,BROADCAST,MULTICAST mtu 1500ether 52:b0:60:45:0a:bc txqueuelen 1000 (Ethernet)RX packets 0 bytes 0 (0.0 B)RX errors 0 dropped 0 overruns 0 frame 0TX packets 0 bytes 0 (0.0 B)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
注意插入网卡后系统会自动启动自带的wpa_supplicant进程此时通过ps命令可以看到wpa_supplicant已经启动
ps aux | grep wpa_supplicant
可以切换到root用户使用airmon-ng工具关闭系统自带的wpa_supplicant进程再切换回普通用户
sudo apt-get install aircrack-ng
su root
airmon-ng check kill
此时再输入ifconfig已经看不到wlan的网卡了但是输入ip link可以看到wlan0网卡
3: wlan0: BROADCAST,MULTICAST mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000link/ether c0:1c:30:2f:ef:5d brd ff:ff:ff:ff:ff:ff 2.2 启动wpa_supplicant程序
启动本文编译的wpa_supplicant即可
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
sudo ./wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
上述命令中各参数说明如下
- 参数-D表示指定驱动上述命令指定了nl80211驱动 - 参数-i表示指定网卡接口上述命令指定了wlan0 - 参数-c表示指定conf文件路径上述命令指定为/etc/wpa_supplicant/wpa_supplicant.conf
若提示已经运行了wpa_supplicant初始化wpa_supplicant失败如下
ctrl_iface exists and seems to be in use - cannot override it
Delete /var/run/wpa_supplicant/wlan0 manually if it is not used anymore
Failed to initialize control interface /var/run/wpa_supplicant.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.wlan0: CTRL-EVENT-DSCP-POLICY clear_all
wlan0: CTRL-EVENT-DSCP-POLICY clear_all
nl80211: deinit ifnamewlan0 disabled_11b_rates0
则运行以下命令删除已经存在的socket文件wlan0并杀死所有的wpa_supplicant进程
sudo rm /var/run/wpa_supplicant/wlan0
sudo killall wpa_supplicant
也可以切换到root用户使用airmon-ng工具关闭wpa_supplicant进程再切换回普通用户
sudo apt-get install aircrack-ng
su root
airmon-ng check kill
然后再次启动wpa_supplicant
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant/
sudo ./wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
运行完成后新建终端使用以下命令查看刚才启动的wpa_supplicant是否已经运行
ps aux | grep wpa_supplicant
如果conf文件中配置了有效的无线网络则可以看到类似以下输出
Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-REGDOM-CHANGE initBEACON_HINT typeUNKNOWN
wlan0: CTRL-EVENT-REGDOM-CHANGE initUSER typeCOUNTRY alpha2CN
wlan0: SME: Trying to authenticate with 9c:8c:d8:00:a8:e0 (SSIDi-amlogic freq2412 MHz)
wlan0: Trying to associate with 9c:8c:d8:00:a8:e0 (SSIDi-amlogic freq2412 MHz)
wlan0: Associated with 9c:8c:d8:00:a8:e0

wlan0: CTRL-EVENT-CONNECTED - Connection to 9c:8c:d8:00:a8:e0 completed [id0 id_str]
在另一个终端中使用DHCP获取ip地址
sudo dhclient wlan0
此时输入ifconfig可以看到已经获取到了ip地址
wlan0: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1500inet 10.98.70.196 netmask 255.255.252.0 broadcast 10.98.71.255ether 2e:d0:00:6c:31:e4 txqueuelen 1000 (Ethernet)RX packets 39 bytes 6772 (6.6 KiB)RX errors 0 dropped 0 overruns 0 frame 0TX packets 94 bytes 13072 (12.7 KiB)TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 2.3 启动wpa_cli程序
新建终端运行wpa_cli程序
wpa_cli操作命令示例
wpa_cli -i wlan0 scan //扫描
wpa_cli -i wlan0 scan_result //显示扫描结果
wpa_cli -i wlan0 status //查看状态
wpa_cli -i wlan0 mib //获取设备的mib信息
wpa_cli -i wlan0 ping //pings wpa_supplicantwpa_supplicant收到后回复PONGwpa_cli -i wlan0 add_network //添加网络会返回network id
wpa_cli set_network network id ssid name //设置网络名称
wpa_cli set_network network id psk psk //设置网络密码
wpa_cli set_network network id key_mgmt NONE //无密码的网络
wpa_cli -i wlan0 save_config //保存网络信息到配置文件wpa_cli -i wlan0 list_network //列出网络
wpa_cli -i wlan0 select_network network id //选择网络
wpa_cli -i wlan0 enable_network network id //使能网络也就是连接网络
wpa_cli -i wlan0 disable_network network id //断开网络
更多详细命令输入wpa_cli -h查看
例如要连接test网络密码为password网卡接口为wlan0命令如下
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant/
sudo ./wpa_cli -i wlan0 add_network
sudo ./wpa_cli set_network 0 ssid test
sudo ./wpa_cli set_network 0 psk password
sudo ./wpa_cli -i wlan0 list_network
sudo ./wpa_cli -i wlan0 select_network 0
sudo ./wpa_cli -i wlan0 enable_network 0
最后使用DHCP获取ip地址
sudo dhclient wlan0 3 运行wpa_gui 3.1 直接安装wpagui
wpa_gui是图形化的管理工具需要单独安装安装命令如下
sudo apt-get install wpagui
启动wpa_gui
sudo wpa_gui 3.2 编译安装wpa_gui-qt4
wpa_supplicant项目中也提供了一个wpa_gui-qt4程序
如果直接从wpa_supplicant项目中编译安装也是可以的如下
安装qmake
sudo apt-get install qt5-qmake
查询安装路径
qmake -query | grep bin
结果如下
QT_INSTALL_BINS:/usr/lib/qt5/bin
QT_HOST_BINS:/usr/lib/qt5/bin
添加bin文件的路径到环境变量
export PATH/usr/lib/qt5/bin:$PATH
然后安装qt5-default
sudo apt install qt5-default
sudo apt install libpcap-dev libncurses5-dev libprocps-dev libxtst-dev libxcb-util0-dev qttools5-dev-tools libdtkwidget-dev libdtkwm-dev pkg-config
如果安装失败尝试安装qtbase5-dev
sudo apt-get install qtbase5-dev
sudo apt install libpcap-dev libncurses5-dev libxtst-dev libxcb-util0-dev qttools5-dev-tools libdtkwidget-dev pkg-config
然后进入wpa_supplicant文件目录编译安装wpa_gui-qt4
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
sudo make wpa_gui-qt4
sudo make install wpa_gui-qt4
结果如下
make -C ../src install
for d in ap common crypto drivers eapol_auth eapol_supp eap_common eap_peer eap_server l2_packet p2p pae radius rsn_supp tls utils wps fst; do [ -d $d ] make -C $d install; done

if ls eap_*.so /dev/null 21; then \install -d /usr/local/lib/wpa_supplicant \cp *.so /usr/local/lib/wpa_supplicant \
; fi
make: wpa_gui-qt4 is up to date.
进入目录执行wpa_gui
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant/wpa_gui-qt4
sudo ./wpa_gui 4 修改代码后重新编译wpa_supplicant
应用程序wpa_cli就是通过创建的socket文件/var/run/wpa_supplicant/wlan0与wpa_supplicant程序进行交互
在文件src\utils\wpa_debug.h中可以看到wpa_supplicant的日志级别共有6种如下
enum {MSG_EXCESSIVE, MSG_MSGDUMP, MSG_DEBUG, MSG_INFO, MSG_WARNING, MSG_ERROR
};
查看当前的日志调试级别
sudo ./wpa_cli -p/var/run/wpa_supplicant -iwlan0 log_level
结果如下
Current level: INFO
Timestamp: 0
默认输出的级别为INFO即EXCESSIVE、MSGDUMP、DEBUG级别的日志将不会输出
修改级别为DEBUG
sudo ./wpa_cli -p/var/run/wpa_supplicant -iwlan0 log_level DEBUG
若要在代码中修改调试级别需要修改wpa_supplicant\main.c文件下的main()函数找到对应位置
params.wpa_debug_level MSG_INFO;
修改为
params.wpa_debug_level MSG_DEBUG;
修改wpa_supplicant的源码后重新编译的命令如下
cd ~/Documents
cd wpa_supplicant-2.10/wpa_supplicant
sudo make clean
sudo make
sudo make install 5 参考
