System Administration Commands - Part 3

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):

All times are given in seconds. Synchronization distance is a measure of the goodness of the clock's time.
