networkd -- network daemon. SYNOPSIS
networkd is a launch-on-demand daemon that performs opreations on behalf of code in libystem_network, a component of libSystem. networkd has no user-specifiable command-line argument, and users should not run networkd manually. LOGGING There are several methods with which to examine networkd's internal state for debugging and diagnostic purposes. The syslog(1) logging levels map as follows: Error - Error messages Warning - Non-fatal concerns Notice - Internal state messages Info - Informational messages By default, only log level Notice through Error is logged. Syslog may be used to modify the mask which logging levels are logged. For example, to enable log levels Emergency - Debug : % sudo syslog -c networkd -d The networkd settings file may also be used to change the log level. This method will add some additional logging that may be missing using the syslog technique listed above. This method is also persistent across runs of networkd For example, to enable log levels Emergency (1) through Debug (7): % sudo defaults write /Library/Preferences/ networkd_log_level -int 7 The networkd settings file may also be used to change the log level for code in libsystem_network. For example, to enable log levels Emer- gency (1) through Debug (7) for libsystem_network code: % sudo defaults write /Library/Preferences/ libnetcore_log_level -int 7 A SIGINFO signal will dump a snapshot summary of the internal state to the system log at log level NOTICE : % sudo killall -INFO networkd FILES
/usr/libexec/networkd The binary. /System/Library/LaunchDaemons/ The launchd.plist(5) controlling the networkd job. /Library/Preferences/ An optional preferences file read by networkd. BUGS

systemd-networkd.service, systemd-networkd - Network manager SYNOPSIS
systemd-networkd.service /lib/systemd/systemd-networkd DESCRIPTION
systemd-networkd is a system service that manages networks. It detects and configures network devices as they appear, as well as creating virtual network devices. To configure low-level link settings independently of networks, see systemd-networkd will create network devices based on the configuration in systemd.netdev(5) files, respecting the [Match] sections in those files. systemd-networkd will manage network addresses and routes for any link for which it finds a .network file with an appropriate [Match] section, see For those links, it will flush existing network addresses and routes when bringing up the device. Any links not matched by one of the .network files will be ignored. It is also possible to explicitly tell systemd-networkd to ignore a link by using Unmanaged=yes option, see When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition from the initrams and to restart the service without breaking connectivity. This also means that when configuration is updated and systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up manually. CONFIGURATION FILES
The configuration files are read from the files located in the system network directory /lib/systemd/network, the volatile runtime network directory /run/systemd/network and the local administration network directory /etc/systemd/network. Networks are configured in .network files, see, and virtual network devices are configured in .netdev files, see systemd.netdev(5). SEE ALSO
