.Sh NAME
.Nm ndis_events
.Nd relay events from
.Xr ndis 4
drivers to
.Xr wpa_supplicant 8
.Sh SYNOPSIS
.Nm
.Op Fl d
.Op Fl v
.Sh DESCRIPTION
The
.Nm
utility listens for events generated by an
.Xr ndis 4
wireless network driver and relays them to
.Xr wpa_supplicant 8
for possible processing. The three event types that can occur
are media connect and disconnect events, such as when a wireless
interface joins or leaves a network, and media-specific events.
In particular,
.Xr ndis 4
drivers that support WPA2 will generate media-specific events
containing PMKID candidate information which
.Xr wpa_supplicant 8
needs in order to properly associate with WPA2-capable access points.
.Pp
The
.Nm
daemon works by listening for interface information events via
a routing socket. When it detects an event that was generated by an
.Xr ndis 4
interface, it transmits it via UDP packet on the loopback interface,
where
.Xr wpa_supplicant 8
is presumeably listening. The standard
.Xr wpa_supplicant 8
distribution includes its own version of this utility for use with
.Tn Windows\[rg] .
The
.Fx
version performs the same functions as the
.Tn Windows\[rg]
except that it uses an
.Xr ioctl 4
and routing socket interface instead of WMI.
.Pp
Note that a single instance of
.Nm
is sufficient to scan for events for any number of
.Xr ndis 4
interfaces in a system.
.Sh OPTIONS
The
.Nm
daemon supports the following options:
.Bl -tag -width indent
.It Fl d
Run in debug mode. This causes
.Nm
to run in the foreground and generate any output to the standard
error instead of using the
.Xr syslog 3
facility.
.It Fl v
Run in verbose mode. This causes
.Nm
to emit notifications when it receives events.
.El
.Sh SEE ALSO
.Xr ndis 4 ,
.Xr ndisapi 9 ,
.Xr wpa_supplicant 8
.Sh HISTORY
The
.Nm
utility first appeared in
.Fx 7.0 .
.Sh AUTHORS
The
.Nm
utility was written by
.An Bill Paul Aq wpaul@windriver.com .
