.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
|
|
.br
|
|
.in +4
|
|
.nf
|
|
% 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'
|
|
.in -4
|
|
.fi
|
|
.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"
|
|
.TP
|
|
.NOP \f\*[B-Font]\-n\f[], \f\*[B-Font]\-\-numeric\f[]
|
|
Print IP addresses instead of hostnames.
|
|
.sp
|
|
Output hosts as dotted-quad numeric format rather than converting to
|
|
the canonical host names.
|
|
.TP
|
|
.NOP \f\*[B-Font]\-m\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-max\-hosts\f[]=\f\*[I-Font]number\f[]
|
|
Maximum number of peers to trace.
|
|
This option takes an integer number as its argument.
|

The default
|
|
\f\*[I-Font]number\f[]
|
|
for this option is:
|
|
.ti +4
|
|
99

|
|
Single remote host.
|
|
The default
|
|

|
|
Output version of program and exit. The default mode is `v', a simple
|
|
version. The `c' mode will print copyright information and `n' will
|
|
