A device with carrier ignored will allow activating connections on that device even when it does not have carrier, provided that the connection uses only statically-configured IP addresses. Additionally, it will allow any active connection whether static or dynamic to remain active on the device when carrier is lost.
Note that the "carrier" property of NMDevices and device D-Bus interfaces will still reflect the actual device state; it's just that NetworkManager will not make use of that information. Master types like bond, bridge and team ignore carrier by default, while other device types react on carrier changes by default.
This setting overwrites the deprecated main. This defaults to yes in which case a random, locally-administered MAC address will be used. The setting wifi. If disabled, the MAC address during scanning is left unchanged to whatever is configured. For the configured MAC address while the device is associated, see instead the per-connection setting wifi. Specify the Wi-Fi backend used for the device.
Like the per-connection settings ethernet. See nm-settings 5 for details. If wifi. Leaving it true default stops NetworkManager from automatically initiating connections and allows IWD to use its network ranking and scanning logic to decide the best networks to autoconnect to next. Connections' autoconnect-priority , autoconnect-retries settings will be ignored. Other settings like permissions or multi-connect may interfere with IWD connection attempts.
The [device] section works the same as the [connection] section. That is, multiple sections that all start with the prefix "device" can be specified. The settings "match-device" and "stop-match" are available to match a device section on a device. The order of multiple sections is also top-down within the file and later files overwrite previous settings. This section controls NetworkManager's optional connectivity checking functionality.
This allows NetworkManager to detect whether or not the system can actually access the internet or whether it is behind a captive portal. Connectivity checking serves two purposes. For one, it exposes a connectivity state on D-Bus, which other applications may use.
For example, Gnome's portal helper uses this as signal to show a captive portal login page. This has the purpose to give a better default-route to devices that have global connectivity.
Whether connectivity check is enabled. Note that to enable connectivity check, a valid uri must also be configured. The value defaults to true, but since the uri is unset by default, connectivity check may be disabled. The main purpose of this option is to have a single flag to disable connectivity check. The URI of a web page to periodically request when connectivity is being checked. This page should return the header "X-NetworkManager-Status" with a value of "online".
Alternatively, its body content should be set to "NetworkManager is online". The body content check can be controlled by the response option.
If this option is blank or missing, connectivity checking is disabled. Specified in seconds; controls how often connectivity is checked when a network connection exists.
If set to 0 connectivity checking is disabled. If missing, the default is seconds. If set, controls what body content NetworkManager checks for when requesting the URI for connectivity checking. Note that this only compares that the HTTP response starts with the specifid text, it does not compare the exact string. This behavior might change in the future, so avoid relying on it. If missing, the response defaults to "NetworkManager is online".
If set to empty, the HTTP server is expected to answer with status code or send no data. Sections with a name starting with the "global-dns-domain-" prefix allow to define global DNS configuration for specific domains.
The part of section name after "global-dns-domain-" specifies the domain name a section applies to. A default domain section is mandatory. This is a special section that contains options which apply to the configuration file that contains the option. If " false ", the configuration file will be skipped during loading. Note that the main configuration file NetworkManager.
You can also match against the version of NetworkManager. For example the following are valid configurations:. More then one match can be specified. The configuration will be enabled if one of the predicates matches "or". The special prefix "except:" can be used to negate the match. Note that if one except-predicate matches, the entire configuration will be disabled.
In other words, a except predicate always wins over other predicates. If the setting only consists of "except:" matches and none of the negative conditions are satisfied, the configuration is still enabled. Settings plugins for reading and writing connection profiles.
The number of available plugins is distribution specific. The keyfile plugin is the generic plugin that supports all the connection types and capabilities that NetworkManager has. It writes files out in an. See nm-settings-keyfile 5 for details about the file format. The stored connection file may contain passwords, secrets and private keys in plain text, so it will be made readable only to root, and the plugin will ignore files that are readable or writable by any user or group other than root.
See "Secret flag types" in nm-settings 5 for how to avoid storing passwords in plain text. This plugin is always active, and will automatically be used to store any connections that aren't supported by any other active plugin.
Enabling ifcfg-rh implicitly enables ibft plugin, if it is available. This can be disabled by adding no-ibft. When more plugins are specified, the connections are read from all listed plugins. When writing connections, the plugins will be asked to save the connection in the order listed here.
If the first plugin cannot write out that connection type, or can't write out any connections, the next plugin is tried. If none of the plugins can save the connection, the error is returned to the user.
Available plugins: keyfile plugin is the generic plugin that supports all the connection types and capabilities that NetworkManager has. It writes files out in a. For security, it will ignore files that are readable or writeable by any user or group other than root since private keys and passphrases may be stored in plaintext inside the file. It currently supports reading wired, WiFi, and To allow reading and writing of these add keyfile plugin to your configuration as well.
Since it cannot write connections out that support isn't planned , it is usually paired with the keyfile plugin to enable saving and editing of new connections. Most setups should be using the keyfile plugin instead. By default, NetworkManager creates a temporary wired connection for any Ethernet device that is managed and doesn't have a connection configured.
List a device in this option to inhibit creating the default connection for the device. Additionally, it will allow any active connection whether static or dynamic to remain active on the device when carrier is lost. NetworkManager will update resolv. Comma separated list of options to aid debugging. Currently the following values are supported:. Set devices that should be ignored by NetworkManager when using the keyfile plugin. Devices are specified in the following format:.
Multiple entries are separated with semicolons. No spaces are allowed in the value. Remember that NetworkManager controls the default route, so because the interface is ignored, NetworkManager may assign the default route to some other interface. This section controls NetworkManager's logging. The default logging verbosity level.
The ERR level logs only critical errors.
