HOSTAPD执行错误警告解决方法

编译完成的HOSTAPD在开启AP的过程中报错误日志。

错误日志如下：

random: Only 15/20 bytes of strong random data available from /dev/random
random: Not enough entropy pool available for secure operations
WPA: Not enough entropy in random pool for secure operations – update keys later when the first station connects

日志大概就是说他需向随机池子取数取不够了，源码程序是从/dev/random取数据，解决方法把/dev/random替换成/dev/urandom。

打开src/crypto/random.c文件，找到下面语句

fd = open(“/dev/random”, O_RDONLY | O_NONBLOCK);

修改成：

fd = open(“/dev/urandom”, O_RDONLY | O_NONBLOCK);
