Property Details

The “addresses” property

  “addresses”                GPtrArray *

Array of IP addresses.

[type GPtrArray(NMIPAddress)]

Flags: Read / Write


The “dad-timeout” property

  “dad-timeout”              gint

Timeout in milliseconds used to check for the presence of duplicate IP addresses on the network. If an address conflict is detected, the activation will fail. A zero value means that no duplicate address detection is performed, -1 means the default value (either configuration ipvx.dad-timeout override or zero). A value greater than zero is a timeout in milliseconds.

The property is currently implemented only for IPv4.

Flags: Read / Write / Construct

Allowed values: [-1,30000]

Default value: -1

Since: 1.2


The “dhcp-hostname” property

  “dhcp-hostname”            gchar *

If the “dhcp-send-hostname” property is TRUE, then the specified name will be sent to the DHCP server when acquiring a lease. This property and “dhcp-fqdn” are mutually exclusive and cannot be set at the same time.

Flags: Read / Write

Default value: NULL


The “dhcp-send-hostname” property

  “dhcp-send-hostname”       gboolean

If TRUE, a hostname is sent to the DHCP server when acquiring a lease. Some DHCP servers use this hostname to update DNS databases, essentially providing a static hostname for the computer. If the “dhcp-hostname” property is NULL and this property is TRUE, the current persistent hostname of the computer is sent.

Flags: Read / Write / Construct

Default value: TRUE


The “dhcp-timeout” property

  “dhcp-timeout”             gint

A timeout for a DHCP transaction in seconds.

Flags: Read / Write

Allowed values: >= 0

Default value: 0


The “dns” property

  “dns”                      GStrv

Array of IP addresses of DNS servers.

Flags: Read / Write


The “dns-options” property

  “dns-options”              GStrv

Array of DNS options as described in man 5 resolv.conf.

NULL means that the options are unset and left at the default. In this case NetworkManager will use default options. This is distinct from an empty list of properties.

Flags: Read / Write

Since: 1.2


The “dns-priority” property

  “dns-priority”             gint

DNS servers priority.

The relative priority for DNS servers specified by this setting. A lower value is better (higher priority). Zero selects a globally configured default value. If the latter is missing or zero too, it defaults to 50 for VPNs and 100 for other connections.

Note that the priority is to order DNS settings for multiple active connections. It does not disambiguate multiple DNS servers within the same connection profile.

When using dns=default, servers with higher priority will be on top of resolv.conf. To prioritize a given server over another one within the same connection, just specify them in the desired order. When multiple devices have configurations with the same priority, the one with an active default route will be preferred. Negative values have the special effect of excluding other configurations with a greater priority value; so in presence of at least a negative priority, only DNS servers from connections with the lowest priority value will be used.

When using a DNS resolver that supports split-DNS as dns=dnsmasq or dns=systemd-resolved, each connection is used to query domains in its search list. Queries for domains not present in any search list are routed through connections having the '~.' special wildcard domain, which is added automatically to connections with the default route (or can be added manually). When multiple connections specify the same domain, the one with the highest priority (lowest numerical value) wins. If a connection specifies a domain which is subdomain of another domain with a negative DNS priority value, the subdomain is ignored.

Default value: 0

The “dns-search” property

  “dns-search”               GStrv

Array of DNS search domains. Domains starting with a tilde ('~') are considered 'routing' domains and are used only to decide the interface over which a query must be forwarded; they are not used to complete unqualified host names.

Flags: Read / Write


The “gateway” property

  “gateway”                  gchar *

The gateway associated with this configuration. This is only meaningful if “addresses” is also set.

Flags: Read / Write

Default value: NULL


The “ignore-auto-dns” property

  “ignore-auto-dns”          gboolean

When “method” is set to "auto" and this property to TRUE, automatically configured nameservers and search domains are ignored and only nameservers and search domains specified in the “dns” and “dns-search” properties, if any, are used.

Flags: Read / Write / Construct

Default value: FALSE


The “ignore-auto-routes” property

  “ignore-auto-routes”       gboolean

When “method” is set to "auto" and this property to TRUE, automatically configured routes are ignored and only routes specified in the “routes” property, if any, are used.

Flags: Read / Write / Construct

Default value: FALSE


The “may-fail” property

  “may-fail”                 gboolean

If TRUE, allow overall network configuration to proceed even if the configuration specified by this property times out. Note that at least one IP configuration must succeed or overall network configuration will still fail. For example, in IPv6-only networks, setting this property to TRUE on the NMSettingIP4Config allows the overall network configuration to succeed if IPv4 configuration fails but IPv6 configuration completes successfully.

Flags: Read / Write / Construct

Default value: TRUE


The “method” property

  “method”                   gchar *

IP configuration method.

NMSettingIP4Config and NMSettingIP6Config both support "auto", "manual", and "link-local". See the subclass-specific documentation for other values.

In general, for the "auto" method, properties such as “dns” and “routes” specify information that is added on to the information returned from automatic configuration. The “ignore-auto-routes” and “ignore-auto-dns” properties modify this behavior.

For methods that imply no upstream network, such as "shared" or "link-local", these properties must be empty.

For IPv4 method "shared", the IP subnet can be configured by adding one manual IPv4 address or otherwise 10.42.x.0/24 is chosen. Note that the shared method must be configured on the interface which shares the internet to a subnet, not on the uplink which is shared.

Flags: Read / Write

Default value: NULL


The “never-default” property

  “never-default”            gboolean

If TRUE, this connection will never be the default connection for this IP type, meaning it will never be assigned the default route by NetworkManager.

Flags: Read / Write / Construct

Default value: FALSE


The “route-metric” property

  “route-metric”             gint64

The default metric for routes that don't explicitly specify a metric. The default value -1 means that the metric is chosen automatically based on the device type. The metric applies to dynamic routes, manual (static) routes that don't have an explicit metric setting, address prefix routes, and the default route. Note that for IPv6, the kernel accepts zero (0) but coerces it to 1024 (user default). Hence, setting this property to zero effectively mean setting it to 1024. For IPv4, zero is a regular value for the metric.

Flags: Read / Write / Construct

Allowed values: [-1,4294967295]

Default value: -1


The “route-table” property

  “route-table”              guint

Enable policy routing (source routing) and set the routing table used when adding routes.

This affects all routes, including device-routes, IPv4LL, DHCP, SLAAC, default-routes and static routes. But note that static routes can individually overwrite the setting by explicitly specifying a non-zero routing table.

If the table setting is left at zero, it is eligible to be overwritten via global configuration. If the property is zero even after applying the global configuration value, policy routing is disabled for the address family of this connection.

Policy routing disabled means that NetworkManager will add all routes to the main table (except static routes that explicitly configure a different table). Additionally, NetworkManager will not delete any extraneous routes from tables except the main table. This is to preserve backward compatibility for users who manage routing tables outside of NetworkManager.

Flags: Read / Write

Default value: 0

The “routes” property

  “routes”                   GPtrArray *

Array of IP routes.

[type GPtrArray(NMIPRoute)]
