- All configuration files are collectively sorted and processed in lexical order,
- regardless of the directories in which they live. However, files with
- identical filenames replace each other. Files in
- /etc have the highest priority, files in
- /run take precedence over files with the same
- name in /usr/lib. This can be used to override a
- system-supplied configuration file with a local file if needed; a symlink in
- /etc with the same name as a configuration file in
- /usr/lib, pointing to /dev/null,
- disables the configuration file entirely.
-
- Virtual Network Devices
- Netdev files must have the extension .netdev;
- other extensions are ignored. Virtual network devices are created as soon
- as networkd is started.
-
- The [Netdev] section accepts the following
- keys:
-
-
-
- Name
-
- The interface name used when creating the
- bridge. This option is compulsory.
-
-
-
- Kind
-
- The netdev kind. Currently, 'bridge', 'bond' and 'vlan'
- are supported. This option is compulsory.
-
-
-
-
- The [VLAN] section only applies for netdevs of kind 'vlan',
- and accepts the following keys:
-
-
-
- Id
-
- The VLAN ID to use. This option is compulsory.
-
-
-
-
-
-
- Networks
- Network files must have the extension .network;
- other extensions are ignored. Networks are applied to links whenever the links
- appear.
-
- The network file contains a [Match] section,
- which determines if a given network file may be applied to a given device;
- and a [Network] section specifying how the device should
- be configured. The first (in lexical order) of the network files that
- matches a given device is applied.
-
- A network file is said to match a device if each of the entries in the
- [Match] section matches, or if the section is empty.
- The following keys are accepted:
+ network directory /etc/systemd/network.
-
-
- MACAddress
-
- The hardware address.
-
-
-
- Path
-
- The persistent path, as exposed by the udev
- property ID_PATH.
-
-
-
- Driver
-
- The driver currently bound to the device, as
- exposed by the udev property DRIVER.
-
-
-
-
- Type
-
- The device type, as exposed by the udev property
- DEVTYPE.
-
-
-
- Name
-
- The device name, as exposed by the udev property
- INTERFACE.
-
-
-
-
- The [Network] section accepts the following keys:
-
-
-
- Description
-
- A description of the device. This is only used for
- presentation purposes.
-
-
-
- DHCP
-
- A boolean. When true enables basic DHCPv4 support.
-
-
-
- Address
-
- A static IPv4 or IPv6 address and its prefix length,
- separated by a '/' character. The format of the address must
- be as described in
- inet_pton3
- . This is a short-hand for an [Address] section only containing an Address key (see below).
-
-
-
- Gateway
-
- The gateway address, which must be in the format described in
- inet_pton3
- . This is a short-hand for a [Route] section only containing a Gateway key.
-
-
-
- DNS
-
- A DNS server address, which must be in the format described in
- inet_pton3
- .
-
-
-
- Bridge
-
- The name of the bridge to add the configured link to.
-
-
-
- Bond
-
- The name of the bond to add the configured link to.
-
-
-
-
- The [Address] section accepts the following keys:
-
-
-
- Address
-
- As in the [Network] section. This key is mandatory.
-
-
-
- Label
-
- An address label.
-
-
-
-
- The [Route] section accepts the following keys:
-
-
-
- Gateway
-
- As in the [Network] section. This key is mandatory.
-
-
-
- Destination
-
- The destination prefix of the route. Possibly followed by a slash and the
- prefixlength, if ommitted a full-length host route is assumed.
-
-
-
-
- The [DHCPv4] section accepts the following keys:
-
-
-
- UseDNS
-
- When true (the default) the DNS servers received from the DHCP server will
- be used, and take precedence over any statically configured ones.
-
-
-
- UseMTU
-
- When true the interface maximum transmission unit from the DHCP server will
- be used on the current link. Defaults to false.
-
-
-
- UseHostname
-
- When true (the default) the hostname received from the DHCP server
- will be used as the transient hostname.
-
-
-
- CriticalConnection
-
- When true the connection will never be torn down even if the DHCP lease
- expires. This is contrary to the DHCP specification, but may be the best choice
- if, say, the root filesystem relies on this connection. Defaults to false.
