hostapd is a user space daemon for access point and authentication servers. It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators, RADIUS client, EAP server, and RADIUS authentication server. The current version supports Linux (Host AP, madwifi, Prism54 drivers) and FreeBSD (net80211).
hostapd is designed to be a "daemon" program that runs in the background and acts as the backend component controlling authentication. hostapd supports separate frontend programs and an example text-based frontend, hostapd_cli, is included with hostapd.

• 简单说，hostapd是一个工作于用户态的daemon程序，用于配置AP和认证服务器等，其中hostapd_cli是一个hostapd的前端命令行。
