NAME

       nm-settings - Description of settings and properties of NetworkManager connection profiles

DESCRIPTION

       NetworkManager is based on a concept of connection profiles, sometimes referred to as
       connections only. These connection profiles contain a network configuration. When
       NetworkManager activates a connection profile on a network device the configuration will
       be applied and an active network connection will be established. Users are free to create
       as many connection profiles as they see fit. Thus they are flexible in having various
       network configurations for different networking needs. The connection profiles are handled
       by NetworkManager via settings service and are exported on D-Bus
       (/org/freedesktop/NetworkManager/Settings/<num> objects). The conceptual objects can be
       described as follows:

       Connection (profile)
           A specific, encapsulated, independent group of settings describing all the
           configuration required to connect to a specific network. It is referred to by a unique
           identifier called the UUID. A connection is tied to a one specific device type, but
           not necessarily a specific hardware device. It is composed of one or more Settings
           objects.

       Setting
           A group of related key/value pairs describing a specific piece of a Connection
           (profile). Settings keys and allowed values are described in the tables below. Keys
           are also referred to as properties. Developers can find the setting objects and their
           properties in the libnm-core sources. Look for the *_class_init functions near the
           bottom of each setting source file.

       The settings and properties shown in tables below list all available connection
       configuration options. However, note that not all settings are applicable to all
       connection types. NetworkManager provides a command-line tool nmcli that allows direct
       configuration of the settings and properties according to a connection profile type.
       nmcli connection editor has also a built-in describe command that can display description
       of particular settings and properties of this page.

   connection setting
       General Connection Profile Settings.

   Secret flag types:
       Each password or secret property in a setting has an associated flags property that
       describes how to handle that secret. The flags property is a bitfield that contains zero
       or more of the following values logically OR-ed together.

       ·   0x0 (none) - the system is responsible for providing and storing this secret. This may
           be required so that secrets are already available before the user logs in. It also
           commonly means that the secret will be stored in plain text on disk, accessible to
           root only. For example via the keyfile settings plugin as described in the "PLUGINS"
           section in NetworkManager.conf(5).

       ·   0x1 (agent-owned) - a user-session secret agent is responsible for providing and
           storing this secret; when it is required, agents will be asked to provide it.

       ·   0x2 (not-saved) - this secret should not be saved but should be requested from the
           user each time it is required. This flag should be used for One-Time-Pad secrets, PIN
           codes from hardware tokens, or if the user simply does not want to save the secret.

       ·   0x4 (not-required) - in some situations it cannot be automatically determined that a
           secret is required or not. This flag hints that the secret is not required and should
           not be requested from the user.
