    <title>Description</title>
    <para><literal>NetworkManager.conf</literal> is the configuration file for NetworkManager. It is used
    to set up various aspects of NetworkManager's behavior. The
    location of the main file and configuration directories may be changed
    through use of the <option>--config</option>, <option>--config-dir</option>,
    <option>--system-config-dir</option>, and <option>--intern-config</option>
    argument for NetworkManager, respectively.
    </para>
    <para>If a default <literal>NetworkManager.conf</literal> is
    provided by your distribution's packages, you should not modify
    it, since your changes may get overwritten by package
    updates. Instead, you can add additional <literal>.conf</literal>
    files to the <literal>/etc/NetworkManager/conf.d</literal> directory.
    These will be read in order, with later files overriding earlier ones.
    Packages might install further configuration snippets to <literal>/usr/lib/NetworkManager/conf.d</literal>.
    This directory is parsed first, even before <literal>NetworkManager.conf</literal>.
    Scripts can also put per-boot configuration into <literal>/run/NetworkManager/conf.d</literal>.
    This directory is parsed second, also before <literal>NetworkManager.conf</literal>.
    The loading of a file <literal>/run/NetworkManager/conf.d/<replaceable>name</replaceable>.conf</literal>
    can be prevented by adding a file <literal>/etc/NetworkManager/conf.d/<replaceable>name</replaceable>.conf</literal>.
    Likewise, a file <literal>/usr/lib/NetworkManager/conf.d/<replaceable>name</replaceable>.conf</literal>
    can be shadowed by putting a file of the same name to either <literal>/etc/NetworkManager/conf.d</literal>
    or <literal>/run/NetworkManager/conf.d</literal>.
    </para>
    <para>
    NetworkManager can overwrite certain user configuration options via D-Bus or other internal
    operations. In this case it writes those changes to <literal>/var/lib/NetworkManager/NetworkManager-intern.conf</literal>.
    This file is not intended to be modified by the user, but it is read last and can shadow
    user configuration from <literal>NetworkManager.conf</literal>.
    </para>
    <para>
    Certain settings from the configuration can be reloaded at runtime either by sending SIGHUP signal or via
    D-Bus' Reload call.
    </para>
    <para>
    NetworkManager does not require any configuration in <literal>NetworkManager.conf</literal>. Depending
    on your use case, you may remove all files to restore the default configuration (factory reset). But
    note that your distribution or other packages may drop configuration snippets for NetworkManager, such
    that they are part of the factory default.
    </para>

    <title>File Format</title>
    <para>
      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.
    </para>
    <para>
      For keys that take a list of devices as their value, you can
      specify devices by their MAC addresses or interface names, or
      "*" to specify all devices. See <xref linkend="device-spec"/>
      below.
    </para>
    <para>
      A simple configuration file looks like this:
      <programlisting>
[main]
plugins=keyfile
</programlisting>
    </para>
    <para>
      As an extension to the normal keyfile format, you can also
      append a value to a previously-set list-valued key by doing:
      <programlisting>
plugins+=another-plugin
plugins-=remove-me
</programlisting>
    </para>
  </refsect1>

  <refsect1>

        <listitem>
          <para>
            Lists system settings plugin names separated by ','. These
            plugins are used to read and write system-wide
            connection profiles. When multiple 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, etc. If none of
            the plugins can save the connection, an error is returned
            to the user.
          </para>
          <para>
            The default value and the number of available plugins is
            distro-specific. See <xref linkend="settings-plugins"/>
            below for the available plugins.
            Note that NetworkManager's native <literal>keyfile</literal>
            plugin is always appended to the end of this list (if it doesn't
            already appear earlier in the list).

          <para>
            When set to '<literal>initrd</literal>', NetworkManager does not connect
            to D-Bus and quits after configuring the network. This is an implementation
            detail how the NetworkManager module of dracut can run NetworkManager.
            An alternative to this is having NetworkManager as a systemd service
            with D-Bus in initrd.

          <para>
            The value '<literal>true</literal>' is unsupported since version 1.36.

          </para>
          <para>
            Otherwise, NetworkManager runs a system service with D-Bus and does not

            Set the management mode of the hostname. This parameter will
            affect only the transient hostname. If a valid static hostname is set,
            NetworkManager will skip the update of the hostname despite the value of
            this option. An hostname empty or equal to 'localhost', 'localhost6',
            'localhost.localdomain' or 'localhost6.localdomain' is considered invalid.
          </para>
          <para><literal>default</literal>: NetworkManager will update the
          hostname with the one provided via DHCP or reverse DNS lookup of the
          IP address on the connection with the default route or on any
          connection with the property hostname.only-from-default set to
          '<literal>false</literal>'. Connections are considered in order of
          increasing value of the <literal>hostname.priority</literal>
          property. In case multiple connections have the same priority,
          connections activated earlier are considered first. If no hostname can
          be determined in such way, the hostname will be updated to the last
          one set outside NetworkManager or to 'localhost.localdomain'.
          </para>
          <para><literal>dhcp</literal>: this is similar to
          '<literal>default</literal>', with the difference that after trying to
          get the DHCP hostname, reverse DNS lookup is not done. Note that
          selecting this option is equivalent to setting the property
          '<literal>hostname.from-dns-lookup</literal>' to
          '<literal>false</literal>' globally for all connections in
          NetworkManager.conf.

        <para><literal>default</literal>: NetworkManager will update

        setting (below) controls how this is done.</para>

        <para><literal>dnsmasq</literal>: NetworkManager will run
        dnsmasq as a local caching nameserver, using "Conditional Forwarding"
        if you are connected to a VPN, and then update
        <filename>resolv.conf</filename> to point to the local
        nameserver. It is possible to pass custom options to the
        dnsmasq instance by adding them to files in the
        "<filename>&sysconfdir;/NetworkManager/dnsmasq.d/</filename>"
        directory. Note that when multiple upstream servers are
        available, dnsmasq will initially contact them in parallel and
        then use the fastest to respond, probing again other servers
        after some time. This behavior can be modified passing the
        'all-servers' or 'strict-order' options to dnsmasq (see the
        manual page for more details).</para>

        <para><literal>systemd-resolved</literal>: NetworkManager will

        modify resolv.conf. This implies
        <literal>rc-manager</literal>&nbsp;<literal>unmanaged</literal></para>

        <para>Note that the plugins <literal>dnsmasq</literal> and <literal>systemd-resolved</literal>
        are caching local nameservers.
        Hence, when NetworkManager writes <filename>&nmrundir;/resolv.conf</filename>
        and <filename>/etc/resolv.conf</filename> (according to <literal>rc-manager</literal>
        setting below), the name server there will be localhost only.
        NetworkManager also writes a file <filename>&nmrundir;/no-stub-resolv.conf</filename>
        that contains the original name servers pushed to the DNS plugin.</para>

        <para>When using <literal>dnsmasq</literal> and <literal>systemd-resolved</literal>,
        per-connection added dns servers will always be queried using

        <para>Set the <filename>resolv.conf</filename>
          management mode. This option is about how NetworkManager writes to
          <filename>/etc/resolv.conf</filename>, if at all.
          The default value depends on NetworkManager build
          options, and this version of NetworkManager was build with a default of
          "<literal>&NM_CONFIG_DEFAULT_MAIN_RC_MANAGER;</literal>".
          Regardless of this setting, NetworkManager will
          always write its version of resolv.conf to its runtime state directory
          as <filename>&nmrundir;/resolv.conf</filename>.
        </para>
        <para>If you configure <literal>dns=none</literal> or make <filename>/etc/resolv.conf</filename>
          immutable with <literal>chattr +i</literal>, NetworkManager will ignore this setting and
          always choose <literal>unmanaged</literal> (below).
        </para>
        <para><literal>auto</literal>: if systemd-resolved plugin is configured via
          the <literal>dns</literal> setting or if it gets detected as main DNS plugin,
          NetworkManager will update systemd-resolved without touching <filename>/etc/resolv.conf</filename>.
          Alternatively, if <literal>resolvconf</literal> or <literal>netconfig</literal> are enabled
          at compile time and the respective binary is found, NetworkManager will automatically use it.
          Note that if you install or uninstall these binaries, you need to reload the
          <literal>rc-manager</literal> setting with SIGHUP or
          <literal>systemctl reload NetworkManager</literal>. As last fallback
          it uses the <literal>symlink</literal> option (see next).
        </para>
        <para><literal>symlink</literal>: If <filename>/etc/resolv.conf</filename> is
          a regular file or does not exist, NetworkManager will write the file directly.
          If <filename>/etc/resolv.conf</filename> is instead a symlink, NetworkManager
          will leave it alone. Unless the symlink points to the internal file
          <filename>&nmrundir;/resolv.conf</filename>,
          in which case the symlink will be updated to emit an inotify notification.
          This allows the user to conveniently instruct NetworkManager not
          to manage <filename>/etc/resolv.conf</filename> by replacing it with
          a symlink.
        </para>
        <para><literal>file</literal>: NetworkManager will write
            <filename>/etc/resolv.conf</filename> as regular file. If it finds
            a symlink to an existing target, it will follow the symlink and
            update the target instead. In no case will an existing symlink
            be replaced by a file. Note that older versions of NetworkManager
            behaved differently and would replace dangling symlinks with a
            plain file.

            directory where IWD keeps its network configuration files --
            usually /var/lib/iwd.  NetworkManager will then attempt to
            write copies of new or modified Wi-Fi connection profiles,
            converted into the IWD format, into this directory thus making
            IWD connection properties editable.  NM will overwrite existing

                NetworkManager automatically chooses a filename when storing
                a new profile to disk. That name depends on the profile's name
                (connection.id). When updating a profile's name, the file is
                not renamed to not break scripts that rely on the filename
                for the profile.
                By setting this option to "true", NetworkManager renames
                the keyfile on update of the profile, to follow the profile's
                name. This defaults to "false".

    <title><literal>logging</literal> section</title>
    <para>
    This section controls NetworkManager's logging.
    Logging is very important to understand what NetworkManager is doing.
    When you report a bug, do not unnecessarily filter or limit the log file.
    Just enable <literal>level=TRACE</literal> and <literal>domains=ALL</literal>
    to collect everything.
    </para>

    <para>
    The recommended way for enabling logging is with a file <filename>/etc/NetworkManager/conf.d/95-logging.conf</filename>
    that contains
<programlisting>
[logging]
level=TRACE
domains=ALL
</programlisting>
    and restart the daemon with <command>systemctl restart NetworkManager</command>. Then
    reproduce the problem. You can find the logs in syslog (for example
    <command>journalctl</command>, or <command>journalctl -u NetworkManager</command>
    to show only logs from NetworkManager).
    </para>

    <para>
    Any settings here are overridden by the <option>--log-level</option>
    and <option>--log-domains</option> command-line options.
    Logging can also be reconfigured at runtime with
    <command>nmcli general logging level "$LEVEL" domains "$DOMAINS"</command>.
    However, often it is interesting to get a complete log from the
    start. Especially, when debugging an issue, enable debug logging
    in NetworkManager.conf and restart the service to enable verbose logging
    early on.
    </para>

    <para>
    By setting <option>nm.debug</option> on the kernel command line (either from
    <filename>&nmrundir;/proc-cmdline</filename> or <filename>/proc/cmdline</filename>),
    debug logging is enabled. This overrides both the command-line options and the settings
    from NetworkManager.conf.
    </para>

    <para>
    NetworkManager's logging aims not to contain private sensitive data
    and you should be fine sharing the debug logs. Still, there will
    be IP addresses and your network setup, if you consider that private
    then review the log before sharing. However, try not to mangle the logfile
    in a way that distorts the meaning too much.
    </para>

    <para>
    NetworkManager uses syslog or systemd-journald, depending on configuration.
    In any case, debug logs are verbose and might be rate limited
    or filtered by the logging daemon. For systemd-journald, see
    <literal>RateLimitIntervalSec</literal> and <literal>RateLimitBurst</literal>
    in <literal>journald.conf</literal> manual for how to disable that.

          <para>
          <literal>OFF</literal> disables all logging. <literal>INFO</literal>

          is for debugging.
          </para>
          <para>
          The other levels are in most cases not useful. For example, <literal>DEBUG</literal>
          is between <literal>TRACE</literal> and <literal>INFO</literal>, but it's too
          verbose for regular operation and lacks possibly interesting messages for debugging.
          Almost always, when debugging an issue or reporting a bug, collect full
          level <literal>TRACE</literal> logs to get the full picture.

      Such default values are only consulted if the corresponding per-connection property

      Only if the per-profile property is set to a special value that indicates to use the
      default, the default value from NetworkManager.conf is consulted. It depends on the
      property, which is the special value that indicates fallback to the default, but it
      usually is something like empty, unset values or special numeric values like 0 or -1.
      That means the effectively used value can first always be configured for each profile,

    <refsect2 id="connection-sections" xreflabel="“Sections” under the section called “CONNECTION SECTION”">
    <title>Sections</title>
    <para>
        You can configure multiple <literal>connection</literal>
        sections, by having different sections with a name that all start
        with "connection".
        Example:
<programlisting>
[connection]
ipv6.ip6-privacy=0
connection.autoconnect-slaves=1
vpn.timeout=120

[connection-wifi-wlan0]
match-device=interface-name:wlan0
ipv4.route-metric=50

[connection-wifi-other]
match-device=type:wifi
ipv4.route-metric=55
ipv6.ip6-privacy=1
</programlisting>
    </para>

    <para>
        The sections within one file are considered in order of appearance, with the
        exception that the <literal>[connection]</literal> section is always
        considered last. In the example above, this order is <literal>[connection-wifi-wlan0]</literal>,
        <literal>[connection-wlan-other]</literal>, and <literal>[connection]</literal>.
        When checking for a default configuration value, the sections are searched until
        the requested value is found.
        In the example above, "ipv4.route-metric" for wlan0 interface is set to 50,
        and for all other Wi-Fi typed interfaces to 55. Also, Wi-Fi devices would have
        IPv6 private addresses enabled by default, but other devices would have it disabled.
        Note that also "wlan0" gets "ipv6.ip6-privacy=1", because although the section
        "[connection-wifi-wlan0]" matches the device, it does not contain that property
        and the search continues.
    </para>
    <para>
        When having different sections in multiple files, sections from files that are read
        later have higher priority. So within one file the priority of the sections is
        top-to-bottom. Across multiple files later definitions take precedence.
    </para>

    <para>
      The following properties further control how a connection section applies.

          <literal>match-device</literal>), further sections will not be
          considered even if the property in question is not present. In
          the example above, if <literal>[connection-wifi-wlan0]</literal> would
          have <literal>stop-match</literal> set to <literal>yes</literal>,
          the device <literal>wlan0</literal> would have <literal>ipv6.ip6-privacy</literal>
          property unspecified. That is, the search for the property would not continue
          in the connection sections <literal>[connection-wifi-other]</literal>
          or <literal>[connection]</literal>.

            <para>
              Whether the device is managed or not. A device can be
              marked as managed via udev rules (ENV{NM_UNMANAGED}),
              or via setting plugins (keyfile.unmanaged-devices).
              This is yet another way. Note that this configuration
              can be overruled at runtime via D-Bus. Also, it has
              higher priority then udev rules.

        <varlistentry id="carrier-wait-timeout">
          <term><varname>carrier-wait-timeout</varname></term>
          <listitem>
            <para>
              Specify the timeout for waiting for carrier in milliseconds.
              The default is 6000 milliseconds.
              This setting exists because certain drivers/hardware can take
              a long time to detect whether the cable is plugged in.
            </para>
            <para>
              When the device loses carrier, NetworkManager does not react
              immediately. Instead, it waits for this timeout before considering
              the link lost.
            </para>
            <para>
              Also, on startup, NetworkManager considers the
              device as busy for this time, as long as the device has no carrier.
              This delays startup-complete signal and NetworkManager-wait-online.
              Configuring this too high means to block NetworkManager-wait-online
              longer than necessary when booting with cable unplugged. Configuring
              it too low, means that NetworkManager will declare startup-complete too
              soon, although carrier is about to come and auto-activation to kick in.
              Note that if a profile only has static IP configuration or Layer 3 configuration
              disabled, then it can already autoconnect without carrier on the device.
              Once such a profile reaches full activated state, startup-complete
              is considered as reached even if the device has no carrier yet.

          <listitem>
            <para>
              Specify devices for which NetworkManager will (partially)
              ignore the carrier state. Normally, for
              device types that support carrier-detect, such as Ethernet
              and InfiniBand, NetworkManager will only allow a
              connection to be activated on the device if carrier is
              present (ie, a cable is plugged in), and it will
              deactivate the device if carrier drops for more than a few
              seconds.
            </para>
            <para>
              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.

              On startup, NetworkManager tries to not interfere with
              interfaces that are already configured. It does so by
              generating a in-memory connection based on the interface
              current configuration.
            </para>
            <para>
              If this generated connection matches one of the existing
              persistent connections, the persistent connection gets
              activated. If there is no match, the generated
              connection gets activated as "external", which means
              that the connection is considered as active, but
              NetworkManager doesn't actually touch the interface.
            </para>
            <para>
              It is possible to disable this behavior by setting
              <literal>keep-configuration</literal> to
              <literal>no</literal>. In this way, on startup
              NetworkManager always tries to activate the most
              suitable persistent connection (the one with highest
              autoconnect-priority or, in case of a tie, the one
              activated most recently).
            </para>
            <para>
              Note that when NetworkManager gets restarted, it stores
              the previous state in
              <filename>/run/NetworkManager</filename>; in particular
              it saves the UUID of the connection that was previously
              active so that it can be activated again after the
              restart. Therefore,
              <literal>keep-configuration</literal> does not have
              any effect on service restart.

    <title><literal>connectivity</literal> section</title>

    <para>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.</para>

    <para>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.
    The other use is that default-route of devices without global connectivity
    get a penalty of +20000 to the route-metric. This has the purpose to give a
    better default-route to devices that have global connectivity. For example,
    when being connected to WWAN and to a Wi-Fi network which is behind a captive
    portal, WWAN still gets preferred until login.</para>

    <para>Note that your distribution might set <literal>/proc/sys/net/ipv4/conf/*/rp_filter</literal> to
    strict filtering. That works badly with per-device connectivity checking,
    which uses SO_BINDDEVICE to send requests on all devices. A strict rp_filter
    setting will reject any response and the connectivity check on all but the
    best route will fail.</para>

# only load on versions &gt;= 1.2. Contrary to the previous

# Match against the maximum allowed version. The example matches
