CentOS-6.4无线上网命令行配置

 
待连接的WIFI的ssid为“thm”,密码为12345678,认证方式为WPA2-PSK
 
1. 检查无线网卡驱动是否安装
1 xxx#iwconfig
若打印wlan0(或其他名字)的无线网卡信息,则表明无线网卡驱动已经安装,否则要先安装无线网卡驱动方能继续。
 
2. 配置/etc/sysconfig/network-scripts/ifcfg-wlan0
我的配置文件内容为:
1 DEVICE=wlan0 2 HWADDR=9C:4E:36:9A:64:10

3 TYPE=Wireless 4 UUID=f017bd9c-eebf-46fc-823c-7f76cc8d5abf 5 ONBOOT=no 6 NM_CONTROLLED=yes 7 BOOTPROTO=dhcp 8 ESSID="thm"

3. 安装工具wpa_supplicant

1 xxx#yum install wpa_supplicant

4. 配置/etc/wpa_supplicant/wpa_supplicant.conf,写入相关ssid和对应的密码

1 xxx#wpa_passphrase thm 12345678 >> /etc/wpa_supplicant/wpa_supplicant.conf

我的配置文件内容为:

1 ctrl_interface=/var/run/wpa_supplicant 2 ctrl_interface_group=wheel 3 

4 network={ 5                 ssid="thm"

6                 #psk="12345678"

7                 psk=eabb3e1572789c41a1600051b1235e03c0787c88fc527f6597cd29cb5a707822

5. 后台运行wpa_supplicant进程

1 xxx#wpa_supplicant -B -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

6. 搜索无线网络

1 xxx#iwlist wlan0 scan | grep ESSID

7. 连接无线网络

1 xxx#iwconfig wlan0 essid "thm"

8. dhcp方式获取ip

1 xxx#dhclient wlan0

9. 测试网络是否联通

1 xxx#ping www.baidu.com
