     sdpd -- Bluetooth Service Discovery Protocol daemon

     sdpd [-dh] [-c path] [-g group] [-u user]

     The sdpd daemon keeps track of the Bluetooth services registered on the
     host and responds to Service Discovery inquiries from the remote Blue-
     tooth devices.

     In order to use any service remote Bluetooth device need to send Sevice
     Search and Service Attribute or Service Search Attribute request over
     Bluetooth L2CAP connection on SDP PSM (0x0001).  The sdpd daemon will try
     to find matching Service Record in its Service Database and will send
     appropriate response back.  The remote device then will process the
     response, extract all required information and will make a separate con-
     nection in order to use the service.

     Bluetooth applications, running on the host, register services with the
     local sdpd daemon.  Operation like service registration, service removal
     and service change are performed over the control socket.  It is possible
     to query entire content of the sdpd Service Database with sdpcontrol(8)
     by issuing browse command on the control socket.

     The command line options are as follows:

     -d      Do not detach from the controlling terminal.

     -c path
             Specify path to the control socket.  The default path is

     -g group
             Specifies the group the sdpd should run as after it initializes.
             The value specified may be either a group name or a numeric group
             ID.  This only works if sdpd was started as root.  The default
             group name is ``nobody''.

     -h      Display usage message and exit.

     -u user
             Specifies the user the sdpd should run as after it initializes.
             The value specified may be either a user name or a numeric user
             ID.  This only works if sdpd was started as root.  The default
             user name is ``nobody''.

     The sdpd daemon will listen for incoming L2CAP connections on a wildcard

     In case of multiple Bluetooth devices connected to the same host it is
     possible to specify which services should be ``bound'' to which Bluetooth
     device.  Such assigment should be done at service registration time.

     Access rights on the control socket define which application can regis-
     ter, remove or change the service.  The application must be able to write
     to and read from the control socket in order to perform any query to the
     Service Database via control socket.

     The sdpd daemon does not check for duplicated Service Records.  It only
     performs minimal checking on the service data sent in the Service Regis-
     ter request.  It is assumed that application must obtain all required
     resources such as RFCOMM channels etc., before registering the service.

     Most likely.  Please report if found.
