56 | ||
57 | <para>Network setup is performed by | |
58 | <citerefentry><refentrytitle>systemd-networkd</refentrytitle><manvolnum>8</manvolnum></citerefentry>. | |
59 | </para> | |
60 | ||
61 | <para>Network files must have the extension | |
62 | <filename>.network</filename>; other extensions are ignored. | |
63 | Networks are applied to links whenever the links appear.</para> | |
64 | ||
65 | <para>The <filename>.network</filename> files are read from the | |
66 | files located in the system network directory | |
67 | <filename>/usr/lib/systemd/network</filename>, the volatile | |
68 | runtime network directory | |
69 | <filename>/run/systemd/network</filename> and the local | |
70 | administration network directory | |
71 | <filename>/etc/systemd/network</filename>. All configuration files | |
72 | are collectively sorted and processed in lexical order, regardless | |
73 | of the directories in which they live. However, files with | |
74 | identical filenames replace each other. Files in | |
75 | <filename>/etc</filename> have the highest priority, files in | |
76 | <filename>/run</filename> take precedence over files with the same | |
77 | name in <filename>/usr/lib</filename>. This can be used to | |
78 | override a system-supplied configuration file with a local file if | |
79 | needed; a symlink in <filename>/etc</filename> with the same name | |
80 | as a configuration file in <filename>/usr/lib</filename>, pointing | |
81 | to <filename>/dev/null</filename>, disables the configuration file | |
82 | entirely.</para> | |

87 | <title>[Match] Section Options</title> | |
88 | ||
89 | <para>The network file contains a <literal>[Match]</literal> | |
90 | section, which determines if a given network file may be applied | |
91 | to a given device; and a <literal>[Network]</literal> section | |
92 | specifying how the device should be configured. The first (in | |
93 | lexical order) of the network files that matches a given device | |
94 | is applied.</para> | |
95 | ||
96 | <para>A network file is said to match a device if each of the | |
97 | entries in the <literal>[Match]</literal> section matches, or if | |
98 | the section is empty. The following keys are accepted:</para> | |

286 | unused ranges. The allocated range is checked against all | |
287 | current network interfaces and all known network | |
288 | configuration files to avoid address range conflicts. The | |
289 | default system-wide pool consists of 192.168.0.0/16, | |
290 | 172.16.0.0/12 and 10.0.0.0/8 for IPv4, and fc00::/7 for | |
291 | IPv6. This functionality is useful to manage a large | |

477 | <variablelist class='network-directives'> | |
478 | <varlistentry> | |
479 | <term><varname>UseDNS=</varname></term> | |
480 | <listitem> | |
481 | <para>When true (the default), the DNS servers received | |
482 | from the DHCP server will be used and take precedence over | |
483 | any statically configured ones.</para> | |

486 | <varlistentry> | |
487 | <term><varname>UseMTU=</varname></term> | |
488 | <listitem> | |
489 | <para>When true, the interface maximum transmission unit | |
490 | from the DHCP server will be used on the current link. | |
491 | Defaults to false.</para> | |
492 | </listitem> | |
493 | </varlistentry> | |
494 | <varlistentry> | |
495 | <term><varname>SendHostname=</varname></term> | |
496 | <listitem> | |
497 | <para>When true (the default), the machine's hostname will be sent to the DHCP | |
498 | server</para> | |
499 | </listitem> | |
500 | </varlistentry> | |
501 | <varlistentry> | |
502 | <term><varname>UseHostname=</varname></term> | |
503 | <listitem> | |
504 | <para>When true (the default), the hostname received from | |
505 | the DHCP server will be used as the transient | |
506 | hostname.</para> | |
507 | </listitem> | |
508 | </varlistentry> | |
509 | <varlistentry> | |
510 | <term><varname>UseDomains=</varname></term> | |
511 | <listitem> | |
512 | <para>When true (not the default), the domain name | |
513 | received from the DHCP server will be used for DNS | |
514 | resolution over this link.</para> | |
515 | </listitem> | |
516 | </varlistentry> | |
517 | <varlistentry> | |
518 | <term><varname>UseRoutes=</varname></term> | |
519 | <listitem> | |
520 | <para>When true (the default), the static routes will be | |
521 | requested from the DHCP server and added to the routing | |
522 | table with metric of 1024.</para> | |
523 | </listitem> | |
524 | </varlistentry> | |
525 | <varlistentry> | |
526 | <term><varname>CriticalConnection=</varname></term> | |
527 | <listitem> | |
528 | <para>When true, the connection will never be torn down | |
529 | even if the DHCP lease expires. This is contrary to the | |
530 | DHCP specification, but may be the best choice if, say, | |
531 | the root filesystem relies on this connection. Defaults to | |
532 | false.</para> | |
533 | </listitem> | |
534 | </varlistentry> | |
535 | <varlistentry> | |
536 | <term><varname>VendorClassIdentifier=</varname></term> | |

541 | </varlistentry> | |
542 | <varlistentry> | |
543 | <term><varname>RequestBroadcast=</varname></term> | |
544 | <listitem> | |
545 | <para>Request the server to use broadcast messages before | |
546 | the IP address has been configured. This is necessary for | |
547 | devices that cannot receive RAW packets, or that cannot | |
548 | receive packets at all before an IP address has been | |
549 | configured. On the other hand, this must not be enabled on | |
550 | networks where broadcasts are filtered out.</para> | |

553 | <varlistentry> | |

583 | forwarding database table of a port and accepts the following | |
584 | keys. Specify several <literal>[BridgeFDB]</literal> sections to | |
