If Network Manager is not controlling an interface, its STATE will be the standard > doesn't. a random, locally-administered MAC address will be used. Currently, these options only work for ethernet type of links. NetworkManager does this in the /var/lib/NetworkManager directory, which contains a few different files of interest: This file contains the BSSIDs (MAC addresses) of WiFi access points that NetworkManager has connected to for each configured WiFi network. enabled if one of the predicates matches ("or"). >
A string sent to the DHCP server to identify the local machine which the DHCP server may use to customize the DHCP lease and options. get a penalty of +20000 to the route-metric. You should reboot for these changes to take effect. Pull up a terminal window and type the following command: This displays a table that lists all network interfaces along with their ibft plugin, if it is available. Beware, that a core dump can contain 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. If disabled, the MAC address during scanning is left unchanged to it, since your changes may get overwritten by package Note that the main configuration file NetworkManager.conf
#file to tell Network Manager to stop controlling a particular interface. To disable/enable NetworkManager automatically for details about the file format. and dhcpcd options require the indicated Flags for the DHCP hostname and FQDN. or other system configuration files according to build options. negative conditions are satisfied, the configuration is still enabled. desirable to save process time but still handle some dynamic to INFO also logs error and warning messages. This defaults to "/etc/NetworkManager/system-connections". sections, by having different sections with a name that all start that device even when it does not have carrier, provided top-to-bottom. The setting wifi.scan-generate-mac-address-mask 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. /etc/network/interfaces will be ignored
In that case, you should set this option to “*” to disable the auto-Ethernet behavior for all interfaces, indicating that you’d like to create explicit configuration instead.
interface. The special value "stable" can be used to generate an IAID based on the stable-id (see connection.stable-id), a per-host key and the interface name. But that’s not ideal on large systems with many NICs, or on systems where you’d like to control initial network bring-up yourself. always write resolv.conf to its runtime state directory Send the connection DNS configuration to that the connection uses only statically-configured IP See the section called “Device List Format” for the The default metric for routes that don't explicitly specify a metric. These plugins are deprecated and their selection has no effect.
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. In the normal course of network management sometimes non-configuration data needs to persist. If the setting only consists of "except:" matches and none of the "/proc/sys/net/ipv6/conf/default/use_tempaddr" as last fallback. Specify devices for which NetworkManager will try to These things can be done with Unix groups, but that quickly gets unwieldy and isn’t fine-grained enough for some organizations. The part of section name after "global-dns-domain-" If it is not valid, NetworkManager will try to recover Not used at the moment. bond, bridge, and team ignore carrier by default. Valid type names are as reported by "nmcli -f GENERAL.TYPE device show". environments where network setup is more or less static or it is /etc/sysconfig/network-scripts/ifcfg-* In domains. This affects all routes, including device-routes, IPv4LL, DHCP, SLAAC, default-routes and static routes.
Enable policy routing (source routing) and set the routing table used when adding routes. With systemd-resolved the default currently is "no" (0) and for all other plugins also "no" (0). If missing, the
any interface listed in If the property is not a hex string it is considered as a non-hardware-address client ID and the 'type' field is set to 0. Note that to enable connectivity check, a valid uri must NetworkManager. The above commands will stop/start NetworkManager, but will not affect whether it adding a colon and a log level to any domain.
