NTPTRACE(1)		  BSD General Commands Manual		   NTPTRACE(1)

NAME
     ntptrace — Trace peers of an NTP server

SYNOPSIS
     ntptrace [-flags] [-flag [value]] [--option-name[[=| ]value]] [host]

DESCRIPTION
     ntptrace is a perl script that uses the ntpq utility program to follow
     the chain of NTP servers from a given host back to the primary time
     source. For ntptrace to work properly, each of these servers must imple‐
     ment the NTP Control and Monitoring Protocol specified in RFC 1305 and
     enable NTP Mode 6 packets.

     If given no arguments, ntptrace 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 mea‐
     sured 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
     -n, --numeric
		 Print IP addresses instead of hostnames.

		 Output hosts as dotted-quad numeric format rather than con‐
		 verting to the canonical host names.

     -m number, --max-hosts=number
		 Maximum number of peers to trace.  This option takes an inte‐
		 ger number as its argument.  The default number for this
		 option is:
		      99

		 This option has not been fully documented.

     -r string, --host=string
		 Single remote host.  The default string for this option is:
		      127.0.0.1

		 This option has not been fully documented.

     -?, --help	 Display usage information and exit.

     -!, --more-help
		 Pass the extended usage information through a pager.

     -v [{v|c|n --version [{v|c|n}]}]
		 Output version of program and exit.  The default mode is `v',
		 a simple version.  The `c' mode will print copyright informa‐
		 tion and `n' will print the full copyright notice.

EXIT STATUS
     One of the following exit values will be returned:

     0	(EXIT_SUCCESS)
		   Successful program execution.

     1	(EXIT_FAILURE)
		   The operation failed or the command syntax was not valid.

     70	 (EX_SOFTWARE)
		   libopts had an internal operational error.  Please report
		   it to autogen-users@lists.sourceforge.net.  Thank you.
