安装 hostapd

不建议使用命令 sudo apt-get install hostapd 安装，部分Linux源中的hostapd版本较老，存在问题。wget http://w1.fi/releases/hostapd-2.2.tar.gz

tar xvf hostapd-2.2.tar.gz
cd ./hostapd-2.2/hostapd
make

编译完成后，查看hostapd信息

nixawk@gnu:~/hostapd-2.2/hostapd$ ./hostapd -h
hostapd v2.2
User space daemon for IEEE 802.11 AP management,
IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator

usage: hostapd [-hdBKtv] [-P <PID file>] [-e <entropy file>] \
         [-g <global ctrl_iface>] [-G <group>] \
         <configuration file(s)>

options:
   -h   show this usage
   -d   show more debug messages (-dd for even more)
   -B   run daemon in the background
   -e   entropy file
   -g   global control interface path
   -G   group for control interfaces
   -P   PID file
   -K   include key data in debug messages
   -t   include timestamps in some debug messages
   -v   show hostapd version

创建hostapd配置文件 /etc/hostapd/hostapd.conf

nixawk@gnu:~$ cat /etc/hostapd/hostapd.conf
#change wlan0 to your wireless device
interface=wlan0
driver=nl80211
bridge=br0

auth_algs=1

wpa=2
wpa_passphrase=123456789
wpa_key_mgmt=WPA-PSK

配置网络接口，

nixawk@gnu:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo br0
iface lo inet loopback

# wireless wlan0
allow-hotplug wlan0
iface wlan0 inet manual

# eth0 connected to the ISP router
allow-hotplug eth0
iface eth0 inet manual

# setup birdge
iface br0 inet static
bridge_ports eth0 wlan0
address 192.168.1.11
netmask 255.255.255.0
network 192.168.1.0

## isp router ip, 192.168.1.1 also runs DHCPS ##
gateway 192.168.1.1
dns-nameservers 192.168.1.1
dns-search localdomain

# 配置完成， 请执行 /etc/init.d/networking restart 重新配置网卡接口

# 开启 wifi热点 teeeeeeee
./hostapd -dd /etc/hostapd/hostapd.conf
