Ubuntu uses hostapd to configure Wireless AP

Official Website: http://linuxwireless.org/en/users/documentation/hostapd.

The methods used on the Internet have never been configured successfully. I checked the hostapd version, which is 0.7. I think it may be because the version is too low. I downloaded the reinstallation of hostapd1.1 from the official website. during compilation, two problems:

1. Error: netlink/genl. h: the file or directory does not exist,

Solution: sudo apt-get install libnl-dev

2. Error: openssl/ssl. h: the file or directory does not exist.

Solution: sudo apt-get install libssl-dev

The following error occurs when the instructions on the installation website are configured and links are required:

Random: not enough entropy in random pool for secure operations

I am using the following methods:

mv /dev/random ln -s /dev/urandom /dev/random
