Description

-The Settings interface allows clients to view and administrate the -connections stored and used by NetworkManager. -

Method Details

The ListConnections() method

-ListConnections (OUT ao connections);
-

-List the saved network connections known to NetworkManager. -

---- - - - - -

OUT ao connections:

-List of connections. -

The GetConnectionByUuid() method

-GetConnectionByUuid (IN  s uuid,
-                     OUT o connection);
-

-Retrieve the object path of a connection, given that connection's UUID. -

---- - - - - - - - - - - -

`IN s uuid`:	-The UUID to find the connection object path for. -
`OUT o connection`:	-The connection's object path. -

The AddConnection() method

-AddConnection (IN  a{sa{sv}} connection,
-               OUT o         path);
-

-Add new connection and save it to disk. This operation does not start the -network connection unless (1) device is idle and able to connect to the -network described by the new connection, and (2) the connection is allowed -to be started automatically. -

---- - - - - - - - - - - -

`IN a{sa{sv}} connection`:	-Connection settings and properties. -
`OUT o path`:	-Object path of the new connection that was just added. -

The AddConnectionUnsaved() method

-AddConnectionUnsaved (IN  a{sa{sv}} connection,
-                      OUT o         path);
-

-Add new connection but do not save it to disk immediately. This operation -does not start the network connection unless (1) device is idle and able -to connect to the network described by the new connection, and (2) the -connection is allowed to be started automatically. Use the 'Save' method -on the connection to save these changes to disk. -

---- - - - - - - - - - - -

`IN a{sa{sv}} connection`:	-Connection settings and properties. -
`OUT o path`:	-Object path of the new connection that was just added. -

The AddConnection2() method

-AddConnection2 (IN  a{sa{sv}} settings,
-                IN  u         flags,
-                IN  a{sv}     args,
-                OUT o         path,
-                OUT a{sv}     result);
-

-Add a new connection profile. -

-AddConnection2 is an alternative to -AddConnection and -AddConnectionUnsaved. -The new variant can do everything that the older variants could, and more. -Its behavior is extensible via extra flags and args arguments. -

-The flags argument accepts the combination of following values, -logically or-ed together: -

---- - - - - - - - - - - - - - - -

`0x1 (to-disk)`:	The connection is persisted to disk.
`0x2 (in-memory)`:	The change is only made in memory (without touching an eventual - profile on disk). If neither 0x1 nor 0x2 is set, the change is made in memory - only, if the connection is already in memory only.
`0x20 (block-autoconnect)`:	Blocks auto-connect on the new profile

-The args argument accepts the following keys: -

---- - - - - -

plugin:

The settings plugin the newly added connection will - use, such as "keyfile" or "ifcfg-rh".

Since 1.38

-Either the flags 0x1 (to-disk) or 0x2 (in-memory) must be specified. -The effect is whether to behave like -AddConnection or -AddConnectionUnsaved. -

---- - - - - - - - - - - - - - - - - - - - - - - -

`IN a{sa{sv}} settings`:	-New connection settings, properties, and (optionally) secrets. -
`IN u flags`:	-Flags. Unknown flags cause the call to fail. -
`IN a{sv} args`:	-Optional arguments dictionary, for extentibility. Specifying unknown keys causes the call to fail. -
`OUT o path`:	-Object path of the new connection that was just added. -
`OUT a{sv} result`:	-Output argument, currently no additional results are returned. -

Since 1.20

The LoadConnections() method

-LoadConnections (IN  as filenames,
-                 OUT b  status,
-                 OUT as failures);
-

-Loads or reloads the indicated connections from disk. You should call this -after making changes directly to an on-disk connection file to make sure -that NetworkManager sees the changes. -As with AddConnection(), this operation does not necessarily -start the network connection. -

-Note that before 1.20, NetworkManager had a bug and this status value was wrong. -It is better to assume success if the method does not return with a D-Bus error. -On top of that, you can look at failures to know whether any of the requested files failed. -

---- - - - - - - - - - - - - - - -

`IN as filenames`:	-Array of paths to on-disk connection profiles in directories monitored by NetworkManager. -
`OUT b status`:	-Success or failure of the operation as a whole. True if NetworkManager at least tried to load the indicated connections, even if it did not succeed. False if an error occurred before trying to load the connections (eg, permission denied). -
`OUT as failures`:	-Paths of connection files that could not be loaded. -

The ReloadConnections() method

-ReloadConnections (OUT b status);
-

-Tells NetworkManager to reload all connection files from disk, including -noticing any added or deleted connection files. -

---- - - - - -

OUT b status:

-This always returns TRUE. -

The SaveHostname() method

-SaveHostname (IN  s hostname);
-

-Save the hostname to persistent configuration. -

---- - - - - -

IN s hostname:

-The hostname to save to persistent configuration. If blank, the persistent hostname is cleared. -

Signal Details

The "NewConnection" signal

-NewConnection (o connection);
-

-Emitted when a new connection has been added after NetworkManager has -started up and initialized. This signal is not emitted for connections -read while starting up, because NetworkManager's D-Bus service is only -available after all connections have been read, and to prevent spamming -listeners with too many signals at one time. To retrieve the initial -connection list, call the ListConnections() method once, and then listen -for individual Settings.NewConnection and Settings.Connection.Deleted -signals for further updates. -

---- - - - - -

o connection:

-Object path of the new connection. -

The "ConnectionRemoved" signal

-ConnectionRemoved (o connection);
-

-Emitted when a connection is no longer available. This happens when the -connection is deleted or if it is no longer accessible by any of the -system's logged-in users. After receipt of this signal, the connection no -longer exists and cannot be used. Also see the Settings.Connection.Removed -signal. -

---- - - - - -

o connection:

-Object path of the removed connection. -

Property Details

The "Connections" property

-Connections  readable   ao
-

-List of object paths of available network connection profiles. -

The "Hostname" property

-Hostname  readable   s
-

-The machine hostname stored in persistent configuration. -

The "CanModify" property

-CanModify  readable   b
-

-If true, adding and modifying connections is supported. -

The "VersionId" property

-VersionId  readable   t
-

-The version of the settings. This is incremented whenever the profile -changes and can be used to detect concurrent modifications. -

-Since: 1.44 -
