BTHCID(8)						    BSD System Manager's Manual 						 BTHCID(8)

NAME

     bthcid -- Bluetooth Link Key/PIN Code Manager

SYNOPSIS

     bthcid [-fn] [-d device] [-m mode] [-s socket_name]
     bthcid [-h]

DESCRIPTION

     The bthcid daemon handles Link Key and PIN code requests for Bluetooth devices.  It opens a raw HCI socket and listens for the following HCI
     events.

     Link_Key_Request
	   bthcid scans the /var/db/bthcid.keys file for a cached link key matching the remote device BD_ADDR and, if found, the
	   Link_Key_Request_Reply will be sent back to the device, otherwise the Link_Key_Request_Negative_Reply will be sent.

     Link_Key_Notification
	   When a new link key is created by the device, it will be cached for future use in the /var/db/bthcid.keys link keys file, which will be
	   created if it does not already exist.

     PIN_Code_Request
	   The bthcid daemon checks its PIN cache for a matching remote device entry.  If no PIN is found, the bthcid daemon will send a message
	   to any PIN clients that have registered, with the device details and a timeout value.  When no clients are available or the timeout has
	   expired, bthcid will send a PIN_Code_Request_Negative_Reply back to the device.  When a PIN is found, or if a client responds within
	   the timeout period, a PIN_Code_Request_Reply will be sent back to the device.

	   PINs received from clients will be cached for 5 minutes until used, and may be added to the cache prior to pairing with the btpin(1)
	   utility.

     Some of the functionality of bthcid can be handled by the Bluetooth controller directly, and cached Link Keys may be examined, deleted or
     moved to device storage using the btkey(1) program.

     The command line options are as follows:

     -d device
	   Specify the local Bluetooth device address.	The default is BDADDR_ANY.

     -f    Run in foreground (do not detach).

     -h    Display usage message and exit.

     -m    Specify the file mode access bits for the PIN client socket.  The default is to allow readwrite access to user and group (0660).

     -n    Do not listen for PIN clients.

     -s socket_name
	   Specify the socket name to listen on for PIN clients.  The default path is /var/run/bthcid.

FILES

     /var/db/bthcid.keys
     /var/run/bthcid
     /var/run/bthcid.pid

HISTORY

     The bthcid daemon first appeared in FreeBSD 5.3 as hcsecd.  It was ported to NetBSD 4.0 with its present name and extended to support PIN
     clients by Iain Hibbert under the sponsorship of Itronix, Inc.

NAME

     hcsecd.conf -- hcsecd(8) configuration file

DESCRIPTION

     The hcsecd.conf file is the configuration file for the hcsecd(8) Bluetooth link keys/PIN codes management daemon.

     The hcsecd.conf file is a free-form ASCII text file.  It is parsed by the recursive-descent parser built into hcsecd(8).  The file may con-
     tain extra tabs and newlines for formatting purposes.  Keywords in the file are case-sensitive.  Comments may be placed anywhere within the
     file (except within quotes).  Comments begin with the '#' character and end at the end of the line.

FILE FORMAT

     The hcsecd.conf file consists of a list of device entries.  Each device entry defines a link key or PIN code for a remote Bluetooth device.
     Each remote Bluetooth device is identified by its unique BD_ADDR.

     The device entry

     device { option argument; [option argument;] }

     The following section describes all supported options and arguments.

     bdaddr BD_ADDR
	     Specify remote device BD_ADDR for the entry.

     name device_name
	     Specify user friendly name for the entry.	Name is a string in straight double quotes.

     key link_key
	     Specify link key for the entry.  Link key is hexadecimal string up to 32 characters in length starting with '0x'.

     key nokey
	     Specify no link key for the entry.

     pin PIN_code
	     Specify PIN code for the entry.  PIN code is a string up to 16 characters in length in straight double quotes.

     pin nopin
	     Specify no PIN code for the entry.

EXAMPLES

     A sample hcsecd.conf file:

     # Default entry is applied if no better match found
     # It MUST have 00:00:00:00:00:00 as bdaddr
     device {
	     bdaddr  00:00:00:00:00:00;
	     name    "Default entry";
	     key     nokey;
	     pin     nopin;
     }

     # Ericsson T68 phone
     device {
	     bdaddr  00:80:37:5e:4d:d4;
	     name    "Ericsson T68 phone";
	     key     nokey;
	     pin     "0000"; # PIN code
     }

     # Dummy device
     device {
	     bdaddr  00:11:22:33:44:55;
	     name    "Dummy";
	     key     0x00112233445566778899aabbccddeeff; # 16 bytes key
	     pin     nopin;
     }
