While modifying a couple of servers ntp configs to test their UT1 service I noticed the following that seem odd. If anyone has seen the same I would like to know and if there are plausible explanations I would also be interested.
The issue pertains to server time-c.nist.gov (129.6.15.30) which <http://tf.nist.gov/tf-cgi/servers.cgi> show has all services available. I have just executed ntpdate -d 129.6.15.30 on two different systems. The results are as follows, with uninteresting lines removed. mike@bb1:~$ ntpdate -d 129.6.15.30 2 Aug 08:51:00 ntpdate[26533]: ntpdate [email protected] Tue Jun 30 16:13:49 UTC 2015 (1) Looking for host 129.6.15.30 and service ntp 129.6.15.30 reversed to time-c.nist.gov host found : time-c.nist.gov transmit(129.6.15.30) …. receive(129.6.15.30) server 129.6.15.30, port 123 stratum 2, precision -22, leap 00, trust 000 refid [129.6.15.30], delay 0.11169, dispersion 0.00015 transmitted 4, in filter 4 reference time: d9685702.8297381a Sun, Aug 2 2015 8:44:50.510 ….. offset 0.000847 ntpq -pn on this system showed 129.6.15.30 43.77.130.254 2 u 13 16 377 86.501 1.132 0.582 mike@cubieez2:~/src/python$ sudo ntpdate -d 129.6.15.30 2 Aug 10:50:59 ntpdate[21672]: ntpdate [email protected] Sun Jun 7 13:29:09 UTC 2015 (1) Looking for host 129.6.15.30 and service ntp 129.6.15.30 reversed to time-c.nist.gov host found : time-c.nist.gov transmit(129.6.15.30) ….. receive(129.6.15.30) server 129.6.15.30, port 123 stratum 1, precision -29, leap 00, trust 000 refid [ACTS], delay 0.17868, dispersion 0.00026 transmitted 4, in filter 4 reference time: d968583c.1e7f0dab Sun, Aug 2 2015 10:50:04.119 …. offset -0.008539 (forget the 2hr diff in reported times as the shell for the first command is running with a UTC TZ and the second has a TZ of CEST) ntpq -pn on this system shows 129.6.15.30 .ACTS. 1 u 15 64 377 151.910 -8.515 0.081 What intrigues me is that the refid is not the same. Any idea why? Isn’t having inconsistent data from the same configurations an issue?
