This is the command ntptrace that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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.
Use ntptrace online using onworks.net services
