Dave, The serial offset captured with ntpq and represented with mrtg are: For the best server - ntp1 (Intel PII/366MHz - brand Fujitsu) https://ecoca.eed.usv.ro/mrtg/ntp1usvro_offset.html and, a zoom-ed version of the same graph https://ecoca.eed.usv.ro/mrtg/ntp1usvro_offset_10.html For the second server - ntp2 (AMD K6III/400MHz - no brand) https://ecoca.eed.usv.ro/mrtg/ntp2usvro_offset.html For the third one - ntp3 (Intel P1/200MHz - no brand) https://ecoca.eed.usv.ro/mrtg/ntp3usvro_offset.html I made (at the end of June 2006) for the second server ntp2 a temperature oven for the 14MHz crystal on the motherboard (a basic circuit as for an OCXO) and the graph looks better (it loocked as the graph for ntp3). The yesterday steps in the graphs 2 and 3 at 8 o'clock and 11 o'clock are due to switching off and respectivelly on the air conditioning in the lab - an experiment to see if Kernel PPS is better than driver 22. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
