Hello All, Referred the details given in http://bugs.ntp.org/show_bug.cgi?id=2855 & http://lists.ntp.org/pipermail/bk-ntp-stable-send/2015-June/000690.html for the ntpd implementation with "leapsmear" patch ( for non public servers) I have configured two centos-7 machines one as ntp-server and one as ntp-client: Precisely followed the steps given in the above link: got the latest dev source 4.3.72 (dev version) and used ./configure with --enable-leap-smear as described for the server machine, but could not test the leap smear behavior : problem: "leapsmearoffset" never changes (always 0) , even though smearinterval is large enough anything wrong with configuration this is my "server" centos-machine ntp.conf: ------------------------------------------------------------------ server lrk0090 # take time from a non-smearing server leapsmearinterval 14400 #4 hrs ( but give a smearing time to ur clients) logfile /var/log/ntp.log server 127.127.1.0 # fallback fudge 127.127.1.0 startum 12 ********************************************************** client ntp.conf has regular configuration(nothing special w.r.to smear) and takes the only server as server above ( client anyway is unaware of any leap smearing) server centos 7:> ntpq -c rv ntpq> rv 0 associd=0 status=0618 leap_none, sync_ntp, 1 event, no_sys_peer, version="ntpd 4.3.72@1.2483 Mon Oct 26 09:01:41 UTC 2015 (1)", processor="x86_64", system="Linux/3.10.0-123.el7.x86_64", leap=00, stratum=5, precision=-24, rootdelay=190.562, rootdisp=209.622, refid=132.168.221.17, reftime=d9da05bb.7d286a7a Tue, Oct 27 2015 19:46:27.488, clock=d9da0aa1.82381432 Tue, Oct 27 2015 20:07:21.508, peer=42697, tc=9, mintc=3, offset=-12.969487, frequency=4.020, sys_jitter=12.595202, clk_jitter=10.040, clk_wander=1.133, leapsmearinterval=14400, leapsmearoffset=0.000 the leapflag is 00 ( and no leap second added ?) please let me know if anything wrong with my configuration
