How to sync time with a server on Raspberry Pi?
NTP configuration NTP installation. As I said, NTP is not available by default on Raspberry Pi OS. You need to install it with apt: sudo apt install ntp NTP configuration. The configuration file for NTP is available here: /etc/ntpd.conf You can edit it to set a new server for time synchronization (lines beginning with “pool”).
What can a Raspberry Pi do for the Internet?
The Internet Pi runs Pi-hole for DNS privacy and ad-blocking, and Prometheus and Grafana to provide Internet connection monitoring dashboards. Having a Pi monitoring my Internet continuously makes it easy to see trends over time, or confirm outages.
