Service hierarchy
=================

Service		net.connman
Interface	net.connman.Service
Object path	[variable prefix]/{service0,service1,...}

Methods		dict GetProperties()

			Returns properties for the service object. See
			the properties section for available properties.

			Possible Errors: [service].Error.InvalidArguments

		void SetProperty(string name, variant value)

			Changes the value of the specified property. Only
			properties that are listed as read-write are
			changeable. On success a PropertyChanged signal
			will be emitted.

			Possible Errors: [service].Error.InvalidArguments
					 [service].Error.InvalidProperty

		void ClearProperty(string name)

			Clears the value of the specified property.

			Possible Errors: [service].Error.InvalidArguments
					 [service].Error.InvalidProperty

		void Connect()

			Connect this service. It will attempt to connect
			WiFi, WiMAX or Bluetooth services.

			For Ethernet devices this method can only be used
			if it has previously been disconnected. Otherwise
			the plugging of a cable will trigger connecting
			automatically. If no cable is plugged in this method
			will fail.

			This method call will only return in case of an
			error or when the service is fully connected. So
			setting a longer D-Bus timeout might be a really
			good idea.

			Possible Errors: [service].Error.InvalidArguments

		void Disconnect()

			Disconnect this service. If the service is not
			connected an error message will be generated.

			On Ethernet devices this will disconnect the IP
			details from the service. It will not magically
			unplug the cable. When no cable is plugged in this
			method will fail.

			This method can also be used to abort a previous
			connectiong attempt via the Connect method.

			Possible Errors: [service].Error.InvalidArguments

		void Remove()

			A successfully connected service with Favorite=true
			can be removed this way. If it is connected, it will
			be automatically disconnected first.

			If the service requires a passphrase it will be
			cleared and forgotten when removing.

			This is similar to setting the Favorite property
			to false, but that is currently not supported.

			In the case a connection attempt failed and the
			service is in the State=failure, this method can
			also be used to reset the service.

			Calling this method on Ethernet devices will cause
			an error message. It is not possible to remove these
			kind of devices.

			Possible Errors: [service].Error.InvalidArguments

		void MoveBefore(object service)

			If a service has been used before, this allows a
			reorder of the favorite services.

			The target service object must be part of this
			profile. Moving between profiles is not supported.

			Possible Errors: [service].Error.InvalidArguments

		void MoveAfter(object service)

			If a service has been used before, this allows a
			reorder of the favorite services.

			The target service object must be part of this
			profile. Moving between profiles is not supported.

			Possible Errors: [service].Error.InvalidArguments

		void ResetCounters()

			Reset the counter statistics.

			Possible Errors: None

Signals		PropertyChanged(string name, variant value)

			This signal indicates a changed value of the given
			property.

Properties	string State [readonly]

			The service state information.

			Valid states are "idle", "failure", "association",
			"configuration", "ready" and "online".

			The "ready" state signals a successfully
			connected device. "online" signals that an
			Internet connection is available and has been
			verified.

		string Error [readonly]

			The service error status details.

			When error occur during connection or disconnection
			the detailed information is represented in this
			property to help the user interface to present the
			user with alternate options.

			This property is only valid when the service is in
			the "failure" state. Otherwise it might be empty or
			not present at all.

			Current defined error code is "dhcp-failed".

		string Name [readonly]

			The service name (for example "Wireless" etc.)

			This name can be used for directly displaying it in
			the application. It has pure informational purpose.

			For Ethernet devices and hidden WiFi networks it is
			not guaranteed that this property is present.

		string Type [readonly]

			The service type (for example "ethernet", "wifi" etc.)

			This information should only be used to determine
			advanced properties or showing the correct icon
			to the user.

		string Mode [readonly]

			If the service type is WiFi or Cellular, then this
			property is present and contains the mode of the
			network.

			For WiFi services the possible values are "managed"
			and "adhoc". For Cellular services it describes the
			network technology. Possible values are "gprs", "edge"
			and "umts".

			This property might be only present for WiFi and
			Cellular services.

		string Security [readonly]

			If the service type is WiFi, then this property is
			present and contains the security method or key
			management setting.

			Possible values are "none", "wep", "psk" and
			also "ieee8021x". Alternate values for "psk"
			can also be "wpa" and "rsn".

			This property might be only present for WiFi
			services.

		boolean LoginRequired [readonly]

			This property indicates that an additional login
			step, like web based authentication, is needed
			before the connection establishment can proceed.

		string Passphrase [readwrite]

			If the service type is WiFi, then this property
			can be used to store a passphrase.

			No PropertyChanged signals will be sent for this
			property. The PassphraseRequired property should
			be monitored instead.

			This property might also not always be included
			since it is protected by a different security policy.

		boolean PassphraseRequired [readonly]

			If the service type is WiFi, then this property
			indicates if a passphrase is required.

			If a passphrase has been set already or if no
			passphrase is needed, then this property will
			be set to false.

		boolean WPS [readonly]

			If the service type is Wifi, then this property
			indicates if it provides WPS (Wifi Protected Setup).

			If this is set to true, then if no Passphrase is
			provided or if given Passphrase is wrong, WPS
			push-button or pin methods will be available through
			Agent API.

		uint8 Strength [readonly]

			Indicates the signal strength of the service. This
			is a normalized value between 0 and 100.

			This property will not be present for Ethernet
			devices.

		boolean Favorite [readonly]

			Will be true if a cable is plugged in or the user
			selected and successfully connected to this service.

			This value is automatically changed and to revert
			it back to false the Remove() method needs to be
			used.

		boolean Immutable [readonly]

			This value will be set to true if the service is
			configured externally via a configuration file.

			The only valid operation are Connect() and of
			course Disconnect(). The Remove() method will
			result in an error.

		boolean AutoConnect [readwrite]

			If set to true, this service will auto-connect
			when no other connection is available.

			The service won't auto-connect while roaming.

			For favorite services it is possible to change
			this value to prevent or permit automatic
			connection attempts.

		boolean SetupRequired [readonly]

			If the service is Cellular, then this property
			indicates that some extra setup steps are required.

			In most cases it is required to fill in the APN
			details.

		string APN [readwrite]

			If the service is Cellular, then this property
			contains the APN details.

			The APN is network provider specific and even
			sometimes data plan specific. Possible examples
			are "isp.cingular" or "internet.t-mobile".

		boolean Roaming [readonly]

			This property indicates if this service is roaming.

			In the case of Cellular services this normally
			indicates connections to a foreign provider when
			traveling abroad.

		array{string} Nameservers [readonly]

			The list of currently active nameservers for this
			service. If the server is not in READY or ONLINE
			state than this list will be empty.

			Global nameservers are automatically added to this
			list. The array represents a sorted list of the
			current nameservers. The first one has the highest
			priority and is used by default.

			When using DHCP this array represents the nameservers
			provided by the network. In case of manual settings,
			the ones from Nameservers.Configuration are used.

		array{string} Nameservers.Configuration [readwrite]

			The list of manually configured domain name
			servers. Some 3G networks don't provide correct
			name servers and this allows for an override.

			This array is sorted by priority and the first
			entry in the list represents the nameserver with
			the highest priority.

			When using manual configuration and no global
			nameservers are configured, then it is useful
			to configure this setting.

			Changes to the domain name servers can be done
			at any time. It will not cause a disconnect of
			the service. However there might be small window
			where name resolution might fail.

		array{string} Domains [readonly]

			The list of currently used search domains.

		array{string} Domains.Configuration [readwrite]

			The list of manually configured search domains.

		dict Proxy [readonly]

			string Method [readonly]

				Possible values are "direct", "auto" and
				"manual".

				In case of "auto" method, the URL file can be
