Scripts in /etc/ppp/ip-up.d and /etc/ppp/ip-down.d use chronyc -# commands to switch it on when a dialup link comes up and off when it goes -# down. Code in /etc/init.d/chrony attempts to determine whether or not -# the link is up at boot time and set the online status accordingly. If -# you have an always-on connection such as cable omit the 'offline' -# directive and chronyd will default to online. -# -# Note that if Chrony tries to go "online" and dns lookup of the servers -# fails they will be discarded.
