Be a Time Lord! (Linux+ Objective 1.7.3)

SystemD makes everything weird, but there are basically 3 different time synchronization services in Linux. The simplistic systemd-timesyncd, or the more complicated chrony & ntpd.
By default most systems configure time sync by default -- but if you need to tweak your system, or possible get a more precise clock, you can configure your system. And I'll show you how.
We also cover a couple other services like sshd and syslog. But it's all pretty straightforward. Enjoy!
00:00 - Intro
00:58 - sshd config
03:19 - syslog setup
06:46 - localectl
08:56 - time sync services
10:50 - systemd-timesyncd with ubuntu
14:04 - chronyd with redhat (Rocky Linux)
16:00 - ntpd with debian
17:30 - tl;dr summary

I like to homage to Dali.

[@samplesandtests]

did you setup ntpd manually? both my debian bookworm and bullseye machines are running timesyncd and not ntpd. i will have to go back and see if i selected an option for time management. thanks for the video
