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: [NONE, 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]. When "NONE" is given by
itself, logging is disabled.
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
