NAME

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

SYNOPSIS

       /usr/sbin/ntptrace [-vdn] [-r retries] [-t timeout]
	    [server]

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.

OPTIONS

       The following options are supported:

       -d	     Turns on some debugging output.

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

       -r retries    Sets the number of retransmission attempts for each host.

       -t timeout    Sets the retransmission timeout (in seconds); default = 2.

       -v	     Prints verbose information about the  NTP servers.

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   local-
		  host)

	   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.

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 implement 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
       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

       -n, --numeric
	      Print IP addresses instead of hostnames.

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

       -m number, --max-hosts=number
	      Maximum number of peers to trace.  This option takes an integer 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  information  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.
