RHCSA 7.4: Time service clients

Pointing chrony at one time server, and setting the time zone.

Before you start

The lab adds a time server on your lab network: a second machine, ntp1 (10.99.0.2), running an NTP server. It's the "server on your network" of the chapter, so the lab doesn't need the Internet. The lab notes your time zone and chrony's configuration, and puts them back when you reset it.

Tasks

1. Make this VM synchronize its time only with ntp1 (10.99.0.2), persistently. After a minute, chronyc sources lists only that server, marked ^*.
2. Set the time zone to America/Phoenix.

Hints

• /etc/chrony.conf: comment out the pool line, add a server line with iburst; systemctl restart chronyd; chronyc sources, chronyc tracking.
• If your DHCP server hands out NTP servers, they show up in chronyc sources too: comment out the sourcedir /run/chrony-dhcp line as well.
• timedatectl list-timezones, timedatectl set-timezone, timedatectl.
