networkd(8)               BSD System Manager's Manual              networkd(8)

NAME
     networkd -- network daemon.

SYNOPSIS
     networkd

DESCRIPTION
     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 lev-els levels
     els 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 addi-tional additional
     tional logging that may be missing using the syslog technique listed above. This method is also persis-tent persistent
     tent across runs of networkd For example, to enable log levels Emergency (1) through Debug (7):

           % sudo defaults write /Library/Preferences/com.apple.networkd 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 Emergency (1) through Debug (7) for libsystem_network code:

           % sudo defaults write /Library/Preferences/com.apple.networkd 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/com.apple.networkd.plist
         The launchd.plist(5) controlling the networkd job.

     /Library/Preferences/com.apple.networkd.plist
         An optional preferences file read by networkd.

BUGS
     networkd bugs are tracked in Apple Radar component "networkd".

HISTORY
     networkd first appeared in Mac OS X 10.7.
