ntptrace(1)


NAME

   ntptrace - trace a chain of NTP servers back to the primary source

SYNOPSIS

   ntptrace [ -m max_hops ] [ -n ]

DESCRIPTION

   ntptrace  determines  where  a given Network Time Protocol (NTP) server
   gets its time from, and follows the chain of NTP servers back to  their
   master  time  source.  If given no arguments, it starts with localhost.
   Here is an example of the output from ntptrace:

   % ntptrace
   localhost: stratum 4, offset 0.0019529, synch distance 0.144135
   server2ozo.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): the host name,  the  host
   stratum,  the  time  offset  between  that  host and the local host (as
   measured  by  ntptrace;  this  is  why  it  is  not  always  zero   for
   "localhost"),   the   host  synchronization  distance,  and  (only  for
   stratum-1 servers) the reference clock  ID.  All  times  are  given  in
   seconds.  Note  that the stratum is the server hop count to the primary
   source, while the  synchronization  distance  is  the  estimated  error
   relative  to  the  primary source. These terms are precisely defined in
   RFC-1305.

OPTIONS

   -m max_hops
          Sets the number of server hops to follow (default = 99).

   -n     Turns off the printing of host names; instead, host IP addresses
          are given. This may be useful if a nameserver is down.

BUGS

   This  program  makes  no  attempt to improve accuracy by doing multiple
   samples.
