Top Forums UNIX for Beginners Questions & Answers NTP synchronised problem in our Centos 7.6 node Post 303039209 by Neo on Thursday 26th of September 2019 04:43:25 AM

Update:

Chrony now running on three of my Linux Ubuntu servers and all four of my Macs ( 2 MBA, I MacMini and 1 MacPro).

So, for the most part I have retired ntpd in favor of chronyd.

All boxes show system times within a few microseconds of NTP time.

I want to take this time to thank gull04 for suggesting Chrony in this earlier post, in this discussion:

So it may well be that I'll have to change to Chrony

I've mostly made the switch thanks to Gull04! Thanks for the idea.

NTP problem.

Hi, I have edited the /etc/inet/ntp.conf file to point to a new time server. When I restart ntp on Solaris 10 using 'svcadm disable/enable ntp' it still points to the old ntp server when I run a 'ntpq -p'. Any ideas? Thanks. Sparcman (4 Replies)

NAME
chrony.conf - chronyd configuration file SYNOPSIS
/etc/chrony.conf DESCRIPTION
chrony is a pair of programs for maintaining the accuracy of computer clocks. chronyd is a background daemon program that can be started at boot time. Assuming that you have found some servers, you need to set up a configuration file to run chrony. The (compiled-in) default location for this file is /etc/chrony.conf. Assuming that your ntp servers are called `a.b.c' and `d.e.f', your chrony.conf file could contain as a minimum server a.b.c server d.e.f server g.h.i However, you will probably want to include some of the other directives described in detail in the documentation supplied with the distri- bution (chrony.txt and chrony.texi). The following directives will be particularly useful : `driftfile', `commandkey', `keyfile'. The smallest useful configuration file would look something like server a.b.c server d.e.f server g.h.i keyfile /etc/chrony.keys commandkey 1 driftfile /etc/chrony.drift SEE ALSO
