|
|
.Nd control link keys and PIN codes for Bluetooth devices
|
|
.Sh SYNOPSIS
|

.Nm

|
|
.Fl f Ar configfile
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
daemon controls link keys and PIN code for Bluetooth devices.
|
|
It opens raw HCI socket and listens for the
|
|
.Dv Link_Key_Request
|
|
and
|
|
.Dv PIN_Code_Request
|
|
HCI events.
|
|
Once appropriate HCI event has been received, the daemon will
|
|
scan configuration file for matching entry.
|
|
The remove device BD_ADDR is used as a key.
|
|
If no matching entry was found, the default entry will be used.
|
|
If no default entry was found then it is assumed that no link key and no PIN code
|
|
exist.
|
|
For any given entry, link key takes precedence over PIN code.
|
|
If link key was not specified, it means device must generate link key from
|
|
PIN code.
|
|
If entry was found and has the link key (or PIN code) then the
|
|
.Dv Link_Key_Request_Reply
|
|
(or
|
|
.Dv PIN_Code_Request_Reply )
|
|
command will be sent back to the device.
|
|
Otherwise, the
|
|
.Dv Link_Key_Request_Negative_Reply
|
|
(or
|
|
.Dv PIN_Code_Request_Negative_Reply )
|
|
command will be sent back to the device.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
daemon currently does not handle HCI
|
|
.Dv Link_Key_Notification
|
|
event and does not cache link keys created from the PIN codes.
|
|
It means that the link key only exists while connection is opened.
|
|
After the connection has been terminated, the user will have to enter PIN code
|
|
again.
|
|
.Pp
|
|
The command line options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
Do not detach from the controlling terminal.
|
|
.It Fl f Ar configfile
|
|
Specify name of the configuration file.
|
|
The default is
|
|
.Pa /usr/local/etc/hcsecd.conf .
|
|
.It Fl h
|
|
Display usage message and exit.
|
|
.El
|
|
.Sh BUGS
|
|
Currently there is no way to select link key or PIN code based on which local
|
|
device received the request.
|
|
Everything is based on remote device BD_ADDR.
|
|
Also might implement interface for external helpers to obtain link keys and
|
|
PIN codes.
