-The

-its time from, and follows the chain of NTP servers back to their
-master time source.
-If given no arguments, it starts with
-.Dq localhost .

-localhost: stratum 4, offset 0.0019529, synch distance 0.144135

+.Sh DESCRIPTION
+\fBntptrace\fP 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.
+.sp
+If given no arguments, ntptrace starts with localhost. Here is an example of
+the output from ntptrace:
+.sp
+.Bd -literal -offset indent
+% 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'

-.Pp
-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
-.Nm ;
-this is why it is not always zero for
-.Dq 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.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl d
-Turn on some debugging output.
-.It Fl n
-Turn off the printing of host names; instead, host IP addresses
-are given.
-This may be necessary if a nameserver is down.
-.It Fl r Ar retries
-Set the number of retransmission attempts for each host; the default is 5.
-.It Fl t Ar timeout
-Set the retransmission timeout (in seconds); the default is 2.
-.It Fl v
-Print verbose information about the NTP servers.
+.sp
+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
+\fBntptrace\fP; 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.
+.Sh "OPTIONS"
+.Bl -tag
+.It Fl n , Fl \-numeric
+Print IP addresses instead of hostnames.
+.sp
+Output hosts as dotted\-quad numeric format rather than converting to
+the canonical host names.
+.It Fl m Ar number , Fl \-max\-hosts Ns = Ns Ar number
+Maximum number of peers to trace.
+This option takes an integer number as its argument.
+The default
+.Ar number
+for this option is:
+.ti +4
+ 99
+.sp
+This option has not been fully documented.
+.It Fl r Ar string , Fl \-host Ns = Ns Ar string
+Single remote host.
+The default
+.Ar string
+for this option is:
+.ti +4
+ 127.0.0.1
+.sp
+This option has not been fully documented.
+.It Fl \&? , Fl \-help
+Display usage information and exit.
+.It Fl \&! , Fl \-more\-help
+Pass the extended usage information through a pager.
+.It Fl v Op Brq Ar v|c|n Fl \-version Op Brq Ar 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.
+.El
+.Sh "EXIT STATUS"
+One of the following exit values will be returned:
+.Bl -tag
+.It 0 " (EXIT_SUCCESS)"
+Successful program execution.
+.It 1 " (EXIT_FAILURE)"
+The operation failed or the command syntax was not valid.
+.It 70 " (EX_SOFTWARE)"
+libopts had an internal operational error. Please report
+it to autogen\-users@lists.sourceforge.net. Thank you.
