Keep your OmniOS server time synced
287 words, 2 minutes
While reading logs, I saw that my OmniOS server was not really time synced with the rest of the Wild Wild World. After a quick check, I realised I forgot to set up NTP on this server.
Let’s solve this now!
Log in to the OmniOS server and install the NTP daemon.
Note that OmniOS uses Image Packaging System (IPS). Other illumos
distributions may use different packaging systems.
# pkg install ntpsec
Once installed, the service is not automatically started.
# svcs -l ntp
fmri svc:/network/ntp:default
name Network Time Protocol (NTP) Version 4
enabled false
state disabled
(...)
I tend to always force a synchronization before starting the daemon.
Mostly because the first adjustment may be too big for ntpd to correct
time in one step.
# ntpdate nl.pool.ntp.org
{"time":"2024-10-18T00:11:36.010467+0200","offset":491.832848,
"precision":0.001872,"host":"nl.pool.ntp.org","ip":"167.99.42.106",
"stratum":2,"leap":"no-leap","adjusted":true,"delay":0.003743}
CLOCK: time stepped by 491.832848
Enable the NTP service and check that it is synchronized properly:
# svcadm enable ntp
# svcs -l ntp
fmri svc:/network/ntp:default
name Network Time Protocol (NTP) Version 4
enabled true
state online
(...)
# ntpq -p
