<title>Description</title>
|
|
|
|
<para><command>systemd-networkd</command> is a system
|
|
service that manages networks. It detects and configures
|
|
network devices as they appear, as well as creating virtual
|
|
network devices.</para>
|
|
|
|
<para>To configure low-level link settings independently of
|
|
networks, see
|
|
<citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
.</para>
|
|
|
|
<para>Network configurations applied before networkd is started
|
|
are not removed, and static configuration applied by networkd
|
|
is not removed when networkd exits. Dynamic configuration applied by
|
|
networkd may also optionally be left in place on shut-down. This ensures
|
|
restarting networkd does not cut the network connection, and, in particular,
|
|
that it is safe to transition between the initrd and the real root,
|
|
and back.</para>
|
|
|
|
<para>Nameservers configured in networkd, or received over DHCP
|
|
are exposed in <filename>/run/systemd/network/resolv.conf</filename>.

|
This file should not be used directly, but only through a symlink

<refsect1><title>Configuration Files</title>

<para>The configuration files are read from the files located in the
|
|
system network directory <filename>/usr/lib/systemd/network</filename>,
|
|
the volatile runtime network directory
|
|
<filename>/run/systemd/network</filename> and the local administration
|
|
network directory <filename>/etc/systemd/network</filename>.</para>
|
|
|
|
<para>Networks are configured in <filename>.network</filename> files, see
|
|
<citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
|
|
and virtual network devices are configured in <filename>.netdev</filename> files, see
