ntptrace4


NAME
     ntptrace4 - trace a chain of NTP hosts back to their  master
     time source

SYNOPSIS
     /usr/sbin/ntptrace4 [-n] [-m maxhosts] [server]

DESCRIPTION
     ntptrace4 determines from where a given Network Time  Proto-
     col  (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  localhost.

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 ntptrace4 Command

     The following example shows the output  from  the  ntptrace4
     command:


       % ntptrace4


        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 ntptrace4; 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.

NOTES
     Source for ntptrace4 is available in the SUNWntp4S package.

     The package name that delivers this program will be  changed
     in the next release and should not be relied on. The name of
     this program will also change at that time, and  should  not
     be relied on.
