NAME
sdpd - Bluetooth Service Discovery Protocol daemon
SYNOPSIS
sdpd [-dh] [-c path] [-g group] [-u user]
DESCRIPTION
The sdpd daemon keeps track of the Bluetooth services registered on the
host and responds to Service Discovery inquiries from the remote
Bluetooth devices.
In order to use any service remote Bluetooth device need to send Service
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
connection 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
/var/run/sdp.
-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".

CAVEATS
Requests to register, remove or change service can only be made via the
control socket. The sdpd daemon will check peer's credentials and will
only accept the request if the application has the same effective user ID
as the "root" user ID.
The sdpd daemon does not check for duplicated Service Records. It only
performs minimal checking on the service data sent in the Service
Register request. It is assumed that application must obtain all
required resources such as RFCOMM channels etc., before registering the
service.
BUGS
Most likely. Please report if found.
