## Description

The NMSettingVPN object is a NMSetting subclass that describes properties necessary for connection to Virtual Private Networks. NetworkManager uses a plugin architecture to allow easier use of new VPN types, and this setting abstracts the configuration for those plugins. Since the configuration options are only known to the VPN plugins themselves, the VPN configuration options are stored as key/value pairs of strings rather than GObject properties.

## Functions

### nm_setting_vpn_error_quark ()

    GQuark
    nm_setting_vpn_error_quark (void);

Registers an error quark for NMSettingVPN if necessary.

#### Returns

### The `“data”` property

      “data”                     GHashTable_gchararray+gchararray_*

Dictionary of key/value pairs of VPN plugin specific data. Both keys and values must be strings.

Flags: Read / Write

### The `“secrets”` property

      “secrets”                  GHashTable_gchararray+gchararray_*

Dictionary of key/value pairs of VPN plugin specific secrets like passwords or private keys. Both keys and values must be strings.

Flags: Read / Write

### The `“service-type”` property

      “service-type”             gchar *

D-Bus service name of the VPN plugin that this setting uses to connect to its network. i.e. org.freedesktop.NetworkManager.vpnc for the vpnc plugin.

Flags: Read / Write

Default value: NULL

### The `“user-name”` property

      “user-name”                gchar *

If the VPN connection requires a user name for authentication, that name should be provided here. If the connection is available to more than one user, and the VPN requires each user to supply a different name, then leave this property empty. If this property is empty, NetworkManager will automatically supply the username of the user which requested the VPN connection.

Flags: Read / Write

Default value: NULL
