For ddclient to work, you will need to do the following:
1) Create configuration file in #{etc}/ddclient, a sample
configuration can be found in #{HOMEBREW_PREFIX}/share/doc/ddclient.
Note: don't enable daemon mode in the configuration file; see
additional information below.
2) Install the launchd item in /Library/LaunchDaemons, like so:
sudo cp -vf #{plist_path} /Library/LaunchDaemons/
sudo chown -v root:wheel /Library/LaunchDaemons/#{plist_path.basename}
3) Start the daemon using:
sudo launchctl load /Library/LaunchDaemons/#{plist_path.basename}
The next reboot of the system will automatically start ddclient.
You can adjust the execution interval by changing the value of
StartInterval (in seconds) in /Library/LaunchDaemons/#{plist_path.basename},
and then
sudo launchctl unload /Library/LaunchDaemons/#{plist_path.basename}
sudo launchctl load /Library/LaunchDaemons/#{plist_path.basename}
