   2 # editing this file use the command 'invoke-rc.d chrony restart' to make

   5 # See www.pool.ntp.org for an explanation of these servers.  Please
   6 # consider joining the project if possible.  If you can't or don't want to
   7 # use these servers I suggest that you try your ISP's nameservers.  We mark
   8 # the servers 'offline' so that chronyd won't try to connect when the link
   9 # is down.  Scripts in /etc/ppp/ip-up.d and /etc/ppp/ip-down.d use chronyc
  10 # commands to switch it on when a dialup link comes up and off when it goes
  11 # down.  Code in /etc/init.d/chrony attempts to determine whether or not
  12 # the link is up at boot time and set the online status accordingly.  If
  13 # you have an always-on connection such as cable omit the 'offline'
  14 # directive and chronyd will default to online.
  15 #
  16 # Note that if Chrony tries to go "online" and dns lookup of the servers
  17 # fails they will be discarded.  Thus under some circumstances it is
  18 # better to use IP numbers than host names.
