DNS Resolver (Unbound) startet und stoppt ständig
-
Hallo!
Ich nutze den DNS Resolver mit ziemlichen Standardsettings und alles läuft soweit auch. Doch in den Logs tauchen ständig Meldungen auf dass Unbound stoppt und wieder startet. Normal?

Mal mit dem General Syslog vergleichen ob da am Interface ständig was getriggert wird. Wenn er alle zu den Zeitpunkten jedes Mal ein GW Failure, neue IP etc. feststellt wird natürlich auch der DNS neu gestartet.

Nö, eigentlich nicht. Das waren die letzten Meldungen:

Mir fällt gerade auf, dass das immer exakt jede Stunde passiert, dazwischen ist nichts.
-
Nutzt du so was wie pfblockerng? Wie ist das das Update Intervall?
-
Nein, gar nichts in die art. Lediglich Suricata. Aber das war auch schon bevor Suricata aktiv war.
-
Evtl. schon in die Crontab geschaut was da getriggert wird?
-
Wo genau findet ich das? Unter Cron habe ich kein Eintrag bzgl. des Resolvers.
-
Kann es sein, dass Du den DHCP Server aktiviert hast und dort die Registrierung der DNS Namen im Unbound aktiviert hast?
-
Ja, habe ich.
-
Das sorgt für den Neustart.
