System Administration Commands                                     ntptrace(8)



NAME
       ntptrace - trace a chain of NTP hosts back to their master time source

SYNOPSIS
       /usr/sbin/ntptrace [-n] [-m maxhosts] [server]

DESCRIPTION
       ntptrace  determines  from  where  a  given Network Time Protocol (NTP)
       server gets its time, and follows the chain of   NTP  servers  back  to
       their master time source. If given no arguments, it starts with  local‐
       host.

OPTIONS
       The following options are supported:

       -n            Turns off the printing of host names;  instead,  host  IP
                     addresses are given.


       -m maxhosts   Sets  the maximum number of levels up the chain that will
                     be followed.


EXAMPLES
       Example 1 Sample Output From the ntptrace Command

       The following example shows the output from the ntptrace command:


         % ntptrace


          localhost: stratum 4, offset 0.0019529, synch distance 0.144135
          server2.bozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
          usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'



       On each line, the fields are (left to right):


           o      The server's host name

           o      The server's stratum

           o      The time offset between that server and the local  host  (as
                  measured  by ntptrace; this is why it is not always zero for
                  localhost)

           o      The host's synchronization distance

           o      The reference clock ID (only for stratum-1 servers)

       All times are given in seconds. Synchronization distance is  a  measure
       of the goodness of the clock's time.
