Dashboard - nur noch IPs unter "Clients"

Guten Morgen,

seit ein paar Tagen werden auf dem Dashboard unter "Top Clients" nur noch die IP angezeigt. Ich habe unter Settings/All Settings/Resolver settings alle Kombinationen versucht.
Im Log werden keine PTR-Requests des localhosts registriert.
nslookup und dig funktionieren in beide Richtungen und werden auch gelogt.

Nur um sicher zu gehen, wenn Du also z.B. auf Deinem Pi-hole selbst den Befehl

dig -x 192.168.0.123 +short @127.0.0.1

ausführst (die IP bitte durch eine geeignete ersetzen), kommt dann die erwartete Antwort?

Was sagt /var/log/pihole/pihole.log zu diesem Zeitpunkt?

Es gibt prinzipiell eine Menge was wir hoer ausprobieren können werden, wir müssen nur erst schauen in welche Richtung es gehen soll.

Genau. Die erwartete Antwort kommt.

Im Log steht:
Dec 2 14:04:12 dnsmasq[38870]: DHCP 192.168.x.x is xxxxx.pilan

Und noch etwas ist mir gerade aufgefallen:

Bei "Query / Advanced filtering" werden unter "Client (by name)" nur noch pi.hole und localhost angeboten.

Hmm, okay. So weit, so seltsam.

Worauf steht es denn gerade jetzt?

Ansonsten bitte einmal debug.resolver auf true setzen und die Datei /var/log/pihole/FTL.log beobachten. Die Namen werden in regelmäßigen Intervallen aktualisiert - es wird sich nicht sofort etwas tun (außer ein neuer Client taucht auf).

resolver.resolveIPv4 enabled
resolver.resolveIPv6 enabled
resolver.networkNames enabled
resolver.refreshNames ALL

Vielleicht ist das interessant:

1.1.1.1 hatte ich kurzfristig mal probiert. Im Moment ist unbound als einziger Resolver aktiv.
Trotzdem taucht 1.1.1.1 im Log auf...

Und das kam zur vollen Stunde:

Und hier haben wir genau das Problem. Hier sollte jetzt eine Liste mit IP Adressen folgen.
Stattdessen stehen hier keine Adressen, d.h. diese Abfrage geht ins Leere und bekommt dadurch natürlich auch keine Antwort....

Ich habe mir den Code noch einmal kritisch angeschaut und dabei festgestellt, dass er sich im Prinzip seit sechs Jahren nicht verändert hat und dies der erste Bericht über einen Fehler ist. Also suchen wir vermutlich nach einer total exotischen Konfiguration, die von uns bislang nicht berücksichtigt wurde.

Tatsächlich habe ich solch eine dann tatsächlich auch gefunden: Wenn das System über keinen einzigen Resolver verfügt, dann könnte sich potenziell der Zustand einstellen, den Du beschreibst.

Dafür habe ich eine mögliche Lösung und würde Dich bitten die auszuprobieren.
Hierfür bitte (ab in ca. 30 min von jetzt an)

pihole checkout ftl fix/no_resolver

ausführen und schauen, ob dies das Problem dann löst. :crossed_fingers:

Falls nicht, dann wäre ich wieder an ein paar Logs (v.A. Zeilen wie Set nameservers to: und was darauf folgt) interessiert, da ich hier das Debug Logging auch noch ein bisschen ergänzt habe.

Die Änderung hat leider noch nicht für Abhilfe gesorgt.

Meine Vermutung hat sich also bestätigt: Auf Deinem System ist scheinbar kein lokaler Resolver konfiguriert - das ist schon merkwürdig. Ich habe versucht das bei mir lokal nachzustellen, bin aber bislang gescheitert... Welches Betriebssystem auf welcher Hardware benutzt Du?

Wie sieht der Inhalt der Datei /etc/resolv.conf bei Dir aus?

Raspberry Pi3 mit DietPi.
Ich habe ein in place Upgrade auf Bookworm gemäß dieser Seite vorgenommen: Debian Bookworm: Testing the upcoming Debian release – DietPi Blog

DietPi, Unbound und Wireguard über DietPi installiert.

resolv.conf:
nameserver 1.1.1.1
nameserver 1.0.0.1

Ich habe in resolv.conf nun als einzigen nameserver 127.0.0.1 eingetragen und er fängt an Namen zu finden. :grinning:

Hmm, ja. Das ist auch die Konfiguration, die ich hier lokal habe. Ich denke immer noch, dass es nicht normal für ein System ist gar keinen Namensserver konfiguriert zu haben, aber dass in solch einem Fall einfach gar nichts funktioniert - auch noch nicht einmal wenn wir manuell dann einen setzen - ist schon merkwürdig.

Bei Gelegenheit werde ich das System neu aufsetzen.
Wenn ich mich recht erinnere gab es bei dieser Konfiguration das Problem, dass DietPi bei einem DietPi-Update alle Prozesse einschließlich Unbound angehalten hat. Das hat dann natürlich auch nicht funktioniert. Vielleicht ist das in der Zwischenzeit anders gelöst.

VIelen Dank für deine Unterstützung.

Das hier entdeckte Problem wird in Zukunft durch

verhindert
