The Hostapd daemon
As already stated earlier, acting as a station is one of the possible way of operation of a common wireless device, but another important one is the access point mode. This mode of functioning can be enabled using the hostapd daemon implemented by the hostapd program.
The hostapd daemon (held in the package of the same name, hostapd) is a special daemon for wireless access point and authentication servers. It can be used to create a wireless hot spot on a GNU/Linux-based computer using compatible wireless interfaces that support the kernel's mac80211 subsystem (and other specific and old drivers such as Host AP, MadWifi, Prism54, and so on).

To show you how to use the hostapd daemon, we can use the BeagleBone Black with the USB pluggable external wireless LAN device shown earlier. We can reproduce a simple access point...
