+.Nm hostapd

+.Op Fl f Ar file
+.Op Fl i Ar interface
+.Sh DESCRIPTION
+.Nm
+is an daemon which allows communication between different 802.11
+wireless access points running in
+.Pa Host AP
+mode.
+.Pp
+.Nm
+implements the Inter Access Points Protocol (IAPP).
+It's purpose is to exchange station association updates between access
+points in large wireless networks.
+IAPP has been designed to speed up roaming between different access
+points in the same
+.Pa BSS .
+IAPP is described in the
+.Pa IEEE 802.11f
+standard.
+.Pp
+.Nm
+additionally allows to monitor and to log stations associations on a
+non-hostap host which is receiving IAPP messages.
+.Pp
+.Nm
+uses two network interfaces as options on startup.
+The first interface
+.Pa ( Fl a Ar interface )
+is used to access the
+.Pa Host AP ,
+which is a wireless interface running in Host AP mode. Please use
+.Xr ifconfig 4
+to enable Host AP mode. The second interface
+.Pa ( Fl i Ar interface )
+is used to communicate with other
+.Nm
+in the same broadcast domain or multicast group.
+Usually a wired interface is used to communicate with other
+.Nm .
+.Pp
+The
+.Nm
+will send an
+.Pa ADD.notify
+IAPP message if a new station has been associated successfully to the
+.Pa Host AP .
+If the
+.Nm
+receives
+.Pa ADD.notify
+messages it will request the
+.Pa Host AP
+to remove a station which has been associated to another access point.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a Ar interface
+Specify the 802.11 wireless network interface running in
+.Pa Host AP
+mode.
+This this option could be omitted to use the
+.Nm
+to log received
+.Pa IAPP
+messages.
+.It Fl b
+Use UDP broadcast instead of multicast group 224.0.1.178 for IAPP
+messages.
+.It Fl D Ar macro Ns = Ns Ar value
+Define
+.Ar macro
+to be set to
+.Ar value
+on the command line.
+Overrides the definition of
+.Ar macro
+in the configuration file.
+.It Fl d
+Do not daemonize and log to
+.Em stderr .
+.It Fl f Ar file
+Use
+.Ar file
+as the configuration file, instead of the default
+.Pa /etc/hostapd.conf .
+.It Fl i Ar interface
+Specify the network interface used to send
+.Pa IAPP
+messages.
+It is important that the IAPP interface is on a trusted
+network because there is no authentication and an attacker could force
+disassociation of selected stations on all listening access points.
+.It Fl v
+Produce more verbose output.

+.Nm
+depends on drivers using the
+.Pa net80211
+kernel wireless layer with support of
+.Pa Host AP mode.
+For traditional reasons,
+the
+.Xr wi 4
+driver still uses it's own Host AP code in
+.Pa if_wi_hostap
+which is not supported by
+.Nm .
