## 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.

#### Parameters

## Property Details

### The `“data”` property

      “data”                     GHashTable *

Owner: NMSettingVpn

Flags: Read / Write

### The `“persistent”` property

      “persistent”               gboolean

If the VPN service supports persistence, and this property is `TRUE`, the VPN will attempt to stay connected across link changes and outages, until explicitly disconnected.

Owner: NMSettingVpn

Flags: Read / Write

Default value: FALSE

### The `“secrets”` property

      “secrets”                  GHashTable *

Owner: NMSettingVpn

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.

Owner: NMSettingVpn

Flags: Read / Write

Default value: NULL

### The `“timeout”` property

      “timeout”                  guint

Timeout for the VPN service to establish the connection. Some services may take quite a long time to connect. Value of 0 means a default timeout, which is 60 seconds (unless overridden by vpn.timeout in configuration file). Values greater than zero mean timeout in seconds.

Owner: NMSettingVpn

Flags: Read / Write

Default value: 0

Since: 1.2

### 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.

Owner: NMSettingVpn

Flags: Read / Write

Default value: NULL
