扫描SSID

# iwlist wlan0 scan |grep ESSID
                    ESSID:"C&X"
                    ESSID:"TP-LINK_516A12"
                    ESSID:"xxxxx"
                    ESSID:"ChinaNet-6fYq"
                    ESSID:"ChinaNet-g5Rd"
                    ESSID:"Daijie"
                    ESSID:"TP-LINK_25B214"

用wpa_passphrase工具生成一个简单的配置文件

 

wpa_passphrase myWirelessSSID myPassword > /etc/wpa_supplicant/wpa_supplicant.conf

其中，“myWirelessSSID”是你的无线网络的SSID，“myPassword”是连接该无线网络的密码。wpa_passphrase工具会根据你提供的这两个信息生成一个非常简单的配置文件，此处我们将输出的信息写入了文件 /etc/wpa_supplicant/wpa_supplicant.conf 中

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

启动网卡：

 

ifconfig wlan0 up

 

连接到网络：

wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

查看连接

 

 

# iwconfig
lo        no wireless extensions.
