ubuntu server 制作 wifi 发射

首先，将wifi的usb模块插入机器中，
然后通过lsusb命令来查看：

Bus 001 Device 004: ID 03f0:241d Hewlett-Packard Gobi 2000 Wireless Modem (QDL mode)
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 413c:2107 Dell Computer Corp. 
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

我们可以查看到：

Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

然后通过ifconfig命令，没有发现新的网卡模块，因此需要对其进行驱动安装：

# ifconfig
docker0   Link encap:Ethernet  HWaddr 56:84:7a:fe:97:99  
          inet addr:172.17.42.1  Bcast:0.0.0.0  Mask:255.255.0.0

          inet addr:192.168.1.118  Bcast:255.255.255.255  Mask:255.255.255.0
          inet6 addr: fe80::20b:abff:fe7f:6f2b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:9968 errors:0 dropped:0 overruns:0 carrier:0

这个realtek的wifi模块，
这个时候我们需要安装驱动，根据其名称RTL8188CUS可以在其官网上找到我们需要的驱动：

http://www.realtek.com/downloads/downloadsView.aspx?Langid=3&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#2742

由于我们采用的是ubuntu server，属于unix（linux）版本中的驱动，点击复杂下载链接，然后我们登录到server中，通过wget即可下载：

#wget ftp://WebUser:wK9xBuD5@58.211.24.153/cn/wlan/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip

           => ‘RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip’

对于zip文件，我们需要对zip文件进行解压缩，可以通过apt源安装unzip来进行解压缩：

# apt-get install unzip 
Reading package lists... Done

Suggested packages:

The following NEW packages will be installed:

然后通过如下命令进行解压缩：

unzip RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip

然后解压后运行install.sh,
遇到如下报错:

make[2]: *** [/home/omnilab/RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911/driver/rtl8188C_8192C_usb_linux_v4.0.2_9000.20130911/os_dep/linux/os_intfs.o] Error 1

然后google之，

apt-get install iw hostapd

然后ifconfig wlan0 up查看
