ntpq is a query tool for ntpd. The -p flag asks for information about the NTP servers (or peers) ntpd is connected to. Your output will be slightly different, but should list the default Debian pool servers plus a few others. Bear in mind that it can take a few minutes for ntpd to establish connections. Step 3 — Switching to systemd-timesyncdSystems that use a CMAC algorithm in ntp.keys will not release a bit of memory on each packet that uses a CMAC key, eventually causing ntpd to run out of memory and fail.
