Tunneldigger und DNS, eine Geschichte voller Mißverständnisse?

Firmware Probleme
1

Fortsetzung der Diskussion von Instabiles Netz an der Müritz:

Die Frage ist, welche IP-Adresse versuchen die Knoten, zu erreichen? (Tunneldigger kann derzeit nicht über IPv6 tunneln.) Mein Verdacht ist ja, daß der tunneldigger-Client auf den Knoten nur beim Start eine DNS-Auflösung vornimmt, damit wäre dann auch das Setup mit gXXmYY.4830.­org weitgehend hinfällig: dies soll eigentlich einen problemlosen Übergang von einem zum anderen Gateway ermöglichen, indem wir einfach im DNS die CNAMEs ändern …

2

würde ja bedeuten, dass direkt nach neustart die chance bestehen müsste auch mal auf l2tp-ber01 zu landen. heute mehrfach probiert: verbindung wird immer nur zu l2tp-fra01 aufgebaut und dahin bricht leider die verbindung ziemlich regelmäßig ab.

kann ich dir/euch noch irgendwelche logs/infos liefern, um das problem besser eingrenzen zu können?

Einmal neu starten, direkt einloggen und mal für 'ne gute Stunde »logread >/tmp/logread.txt« mitlaufen lassen, dann per scp runterziehen und mit als .gz per Mail schicken. Weil, bei mir sieht das so aus:

Warum da g01m01 und g02m01 nicht auftauchen: keine Idee :frowning:

Okay, ich probier’ mich dann mal am Debugging …

Ab 1.2.0~110 ist der neueste Tunneldigger drin mt ein paar zusätzlichen Debugausgaben:

Mal bißchen aufbohren und gucken …

Okay, die KEEPALIVE-Meldungen sollte ich wohl besser wieder rausnehmen ⇒ 1.2.0~112 nehmen, wenn vorhanden.

Demnach haben g01m01.4830.­org & g02m01.4830.­org nicht auf den Cookie- bzw. Usage-Request geantwortet. That’s … odd?

Zumal ja die Verbindung an sich funktoniert zu haben scheint:

hier antwortet scheinbar nur g01m06 auf die auslastungsabfrage ([g01m06.4830.org:10006] Broker usage: 320)

und:

/etc/config/tunneldigger
...
option broker_selection 'usage'

erklärt dann wahrscheinlich auch, warum immer nur dieser server genommen wird (bzw. werden kann → weil von g02m06 keine werte bekannt sind)

Öh? Guckst Du bitte mal, ob auf dem Knoten auf Port 10006 was lauscht? Bei mir (Mesh01 ⇒ 10001) nicht …

Das beweist dann auch, daß die Statusmeldung »connected to …« oben falsch ist; wie auf 127.0.0.1 lauschte auch auch l2tp-ber01/g01m01 nichts auf den angesprochenen Ports. Allerdings macht connect() bei UDP ja auch nicht wirklich etwas, erst beim Senden gäbe es ggf. ICMP_PORT_UNREACHABLE zurück,. Insofern wird in ~113 das Logging nochmal geändert (und die Debugging-Ausgaben korrekt mit LOG_DEBUG geschickt und nicht LOG_INFO).

Ein logread-Auszug von @charrr deutet immerhin darauf hin, daß die DNS-Informationen nach Verbindungsende wieder genullt werden, d. h. eigentlich sollte vor jeder Verbindung die Ziel-IP »frisch« aus dem DNS geholt werden …
