Loxone "Remote Connect" und Cloud DNS Cache

christianTF commented 2 years ago

Die get_clouddns Funktion in System. pm/loxberry_system. php verwendet ein Cachefile 3600+rand(3600) für den Cache.

Wird Loxone "Remote Connect" verwendet, ändert sind in einem Intervall ~10-15 Minuten der Port, sodass der Cache veraltet ist.

Feststellungen:

Der Auth-Test im MS-Widget verwendet den Cache nicht (=Live-Daten).
Das Cachefile für. CLOUD DNS liegt in log/systemtmpfs/. Darin ist auch der Timestamp der nächsten Aktualisierung.
Den Cache haben wir eingeführt, um get_miniservers schneller zu machen, und weil Loxone ab einer gewissen Abfragezahl blockt.

Ermittelt werden müsste:

Gibt es im Cloud DNS Response von Loxone neue Felder/Daten (evt. einen Expiry Timestamp)
Wie häufig wechselt der Port bei Remote Connect
Wie häufig können wir abfragen, ohne gesperrt zu werden

Die Anfrage ergibt folgendes JSON zurück:

curl "http://dns.loxonecloud.com?getip&snr=504XXXXXXFB9&json=true" {"cmd":"getip","Code":200,"IPHTTPS":"168.XXX.XXX.175:38726","PortOpenHTTPS":true,"RemoteConnect":true,"DNS-Status":"registered","DataCenter":"loxonecloud.com"}

Es wäre also möglich auf "RemoteConnect":true zu prüfen und dann das Update-Interval für den Cache nur für RemoteCOnnect zu reduzieren.

Der Port bei Remote Connect wechselt alle 5 Minuten. Die IP der Gegenstelle des SSH Tunnels wechselt in unregelmäßigen Abständen (vermutlich Lastabhängig). Logfile minütliche Abfrage:

Wie relevant für LB3.0 ist das? Der Issue ist ein Jahr alt. ich hab im Forum noch nie von Problemen gehört.... Benutzt das überhaupt jemand außer Wörsty?!

Wir lassen das mal offen.
