软AP的实现------dhcpserver交叉编译

代码版本：dhcp-4.2.5-P1

cd dhcp-4.2.5-P1;
./configure --host=arm-XXX-linux ac_cv_file__dev_random=yes;
cd ./bind;
tar -zxvf bind.tar.gz;

修改Makefile第55行：./configure改成./configure --host=arm-XXX-linux --with-randomdev=/dev/random

修改./bind-9.8.4-P2/lib/export/dns/Makefile.in 169行：
CC改成BUILD_CC
cd ..;make;make install;

运行：

1、给无线网卡设置ip地址和子网掩码

ifconfig wlan0 192.168.1.2 netmask 255.255.255.0

2、创建文件dhcpd.conf

vi dhcpd.conf 

subnet 192.168.1.0 netmask 255.255.255.0 {
       range 192.168.1.3 192.168.1.11;
       option subnet-mask 255.255.255.0;
       option broadcast-address 192.168.1.255;
       option routers 192.168.1.2;
       option domain-name-servers home;
}

 3、创建/var/db/dhcpd.leases

mkdir /var/db;
touch /var/db/dhcpd.leases

4、运行命令

./dhcpd -cf dhcpd.conf wlan0

5、如下图所示：手机已经连接成功，加密类型 WPA2 PSK 并获取ip地址
