Už jsem celekm bezradný. Tímto děkuji za jakoukoliv radu co by mě mohla nasměrovat k řešení.
/run/ntp.conf.dhcp viz status ntp.service.
Take ntpd odmita synchronizovat cas pokud jsou lokalni hodiny prilis posunute proti synchronizacnimu serveru.
Informace o tom co to dela by mely byt v /var/log/ntp.log
Taky se muze hodit:
Zobrazeni stavu ntpd
ntpq -c sysinfo
Informace o peerech, s kterymi se bavi
ntpq -c lpeers

Predpokladam, ze dhcp atribut pro ntp neeexistoval, vytvoril se dhcp konfig a i po uprave nedoslo k restartu ntpd. Taky lze souhlasit s tim co v diskuzi zaznelo, ze je lepsi pouzit chrony namisto ntod pokud neni cilem vytvorit stratum 1 server.
