'''hostapd''' (host access point daemon) is a user space [daemon](/source/daemon_(computing)) software enabling a [network interface card](/source/network_interface_card) to act as an [access point](/source/Wireless_access_point) and [authentication server](/source/authentication_server). There are three implementations: [Jouni Malinen](/source/Jouni_Malinen)'s hostapd, [OpenBSD](/source/OpenBSD)'s hostapd and Devicescape's hostapd.

OpenBSD's hostapd is a user space daemon that improves roaming and monitoring of [OpenBSD](/source/OpenBSD)-based wireless networks. It implements [Inter Access Point Protocol](/source/Inter-Access_Point_Protocol) (IAPP) for exchanging station association information between access points. It can trigger a set of actions like frame injection or logging when receiving specified [IEEE 802.11](/source/IEEE_802.11) frames.

The Open Wireless [Linux](/source/Linux) version of hostapd. It is kept as close as possible to the original open source release, but with OWL specific packaging and defaults.
The website appears to be dead (April 2013), probably as the project itself.
