NAME

ntptrace - trace a chain of NTP servers back to the primary source

 

SYNOPSIS

ntptrace [ -n ] [ -m maxhosts ] [ server ]

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[char46] 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
Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.

BUGS

This program makes no attempt to improve accuracy by doing multiple samples.

Non, je programme en InLine sous Pascal, ce qui convient à mettre des
codes hexadécimaux séparés par Virgule. De plus c'est le code le plus
rapide et le plus petit. Idéal si on veut faire un système rapide et
petit.
