NAME

       NetworkManager.conf - NetworkManager configuration file

SYNOPSIS

       /etc/NetworkManager/NetworkManager.conf
       or
       <SYSCONFDIR>/NetworkManager/NetworkManager.conf
       where <SYSCONFDIR> depends on your distribution or build.

DESCRIPTION

       NetworkManager.conf  is  a configuration file for NetworkManager. It is used to set up various aspects of
       NetworkManager's behavior. The location of the file  may  be  changed  through  use  of  the  "--config="
       argument for NetworkManager (8).

FILE FORMAT

The configuration file format is so-called key file (sort of ini-style format). It consists of sections
(groups) of key-value pairs. Lines beginning with a '#' and blank lines are considered comments. Sections
are started by a header line containing the section enclosed in '[' and ']', and ended implicitly by the
start of the next section or the end of the file. Each key-value pair must be contained in a section.
Minimal system settings configuration file looks like this:

[main]
plugins=keyfile

Description of sections and available keys follows:

[main]
This section is the only mandatory section of the configuration file.

plugins=plugin1,plugin2, ...
List system settings plugin names separated by ','. These plugins are used to read/write system-
wide connection. 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 .ini-style format in
/etc/NetworkManager/system-connections. 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.

ifcfg-rh
plugin is used on the Fedora and Red Hat Enterprise Linux distributions to read and write
configuration from the standard /etc/sysconfig/network-scripts/ifcfg-* files. It currently
supports reading wired, WiFi, and 802.1x connections, but does not yet support reading or
writing mobile broadband, PPPoE, or VPN connections. To allow reading and writing of these
add keyfile plugin to your configuration as well.

ifupdown
plugin is used on the Debian and Ubuntu distributions, and reads connections from
/etc/network/interfaces. 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. The ifupdown plugin supports basic wired and WiFi connections, including WPA-
PSK.

ifcfg-suse
plugin is only provided for simple backward compatibility with SUSE and OpenSUSE
configuration. Most setups should be using the keyfile plugin instead. The ifcfg-suse
plugin supports reading wired and WiFi connections, but does not support saving any
connection types.

dhcp=dhclient | dhcpcd
This key sets up what DHCP client NetworkManager will use. Presently dhclient and dhcpcd are
supported. The client configured here should be available on your system too. If this key is
missing, available DHCP clients are looked for in this order: dhclient, dhcpcd.

no-auto-default=<hwaddr>,<hwaddr>,... | *
Set devices for which NetworkManager shouldn't create default wired connection (Auto eth0).
NetworkManager creates a default wired connection for any wired 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.
When the default wired connection is deleted or saved to a new persistent connection by a plugin,
the MAC address of the wired device is automatically added to this list to prevent creating the
default connection for that device again. Devices are specified by their MAC addresses, in
lowercase. Multiple entries are separated by commas. You can use the glob character * instead of
listing addresses to specify all devices.
Examples:
no-auto-default=00:22:68:5c:5d:c4,00:1e:65:ff:aa:ee
no-auto-default=*

dns=plugin1,plugin2, ...
List DNS plugin names separated by ','. DNS plugins are used to provide local caching nameserver
functionality (which speeds up DNS queries) and to push DNS data to applications that use it.

Available plugins:

dnsmasq
this plugin uses dnsmasq to provide local caching nameserver functionality.

[keyfile]
This section contains keyfile-specific options and thus only has effect when using keyfile plugin.

hostname=<hostname>
Set a persistent hostname when using the keyfile plugin.

unmanaged-devices=mac:<hwaddr>;mac:<hwaddr>;...
Set devices that should be ignored by NetworkManager when using the keyfile plugin. Devices are
specified in the following format: "mac:<hwaddr>", where <hwaddr> is MAC address of the device to
be ignored, in hex-digits-and-colons notation. Multiple entries are separated by a semicolon. No
spaces are allowed in the value.
Example:
unmanaged-devices=mac:00:22:68:1c:59:b1;mac:00:1E:65:30:D1:C4

[ifupdown]
This section contains ifupdown-specific options and thus only has effect when using ifupdown plugin.

managed=false | true
Controls whether interfaces listed in the 'interfaces' file are managed by NetworkManager. If set
to true, then interfaces listed in /etc/network/interfaces are managed by NetworkManager. If set
to false, then any interface listed in /etc/network/interfaces will be ignored by NetworkManager.
Remember that NetworkManager controls the default route, so because the interface is ignored,
NetworkManager may assign the default route to some other interface. When the option is missing,
false value is taken as default.

[logging]
This section controls NetworkManager's logging. Any settings here are overridden by the --log-level and
--log-domains command-line options.

level=<level>
One of [ERR, WARN, INFO, DEBUG]. The ERR level logs only critical errors. WARN logs warnings
that may reflect operation. INFO logs various informational messages that are useful for tracking
state and operations. DEBUG enables verbose logging for debugging purposes. Subsequent levels
also log all messages from earlier levels; thus setting the log level to INFO also logs error and
warning messages.

domains=<domain1>,<domain2>, ...
The following log domains are available: [HW, RFKILL, ETHER, WIFI, BT, MB, DHCP4, DHCP6, PPP,
WIFI_SCAN, IP4, IP6, AUTOIP4, DNS, VPN, SHARING, SUPPLICANT, AGENTS, SETTINGS, SUSPEND, CORE,
DEVICE, OLPC, WIMAX, INFINIBAND, FIREWALL, ADSL, BOND, VLAN, BRIDGE].
In addition to them, these special domains can be used: [NONE, ALL, DEFAULT, DHCP, IP].

NONE = when given by itself, logging is disabled
ALL = all log domains will be switched on
DEFAULT = default log domains
DHCP = a shortcut for "DHCP4, DHCP6"
IP = a shortcut for "IP4, IP6"

HW = Hardware related operations
RFKILL = RFKill subsystem operations
ETHER = Ethernet device operations
WIFI = Wi-Fi device operations
BT = Bluetooth
MB = Mobile Broadband
DHCP4 = DHCP for IPv4
DHCP6 = DHCP for IPv6
PPP = Point-to-point protocol operations
WIFI_SCAN = Wi-Fi scanning operations
IP4 = Domain for IPv4 logging
IP6 = Domain for IPv6 logging
AUTOIP4 = AutoIP (avahi) operations
DNS = Domain Name System related operations
VPN = Virtual Private Network connections and operaions
SHARING = Connection sharing
SUPPLICANT = WPA supplicant related operations
AGENTS = Secret agents operations and communication
SETTINGS = Settings/config service operations
SUSPEND = Suspend/resume
CORE = Core daemon operations
DEVICE = Activation and general interface operations
OLPC = OLPC Mesh device operations
WIMAX = Wimax device operations
INFINIBAND = InfiniBand device operations
FIREWALL = FirewallD related operations
ADSL = ADSL device operations
BOND = Bonding device operations
VLAN = VLAN device operations
BRIDGE = Bridging device operations

[connectivity]
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.

uri=<uri>
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, it's
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.

interval=<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 300 seconds.

response=<response>
If set controls what body content NetworkManager checks for when requesting the URI for
connectivity checking. If missing, defaults to "NetworkManager is online"
