Das war Montag abend das Hauptthema, und da im Syrtaki auch keine v4-IPs vergeben wurden, haben wir ein bißchen gebugged. Es stellte sich heraus, daß mehrere Gateways – sowohl welche, die aktuell als fastd-GWs dienen als auch andere, die vormals für fastd genutzt wurden – durch Updates beeinträchtigt wurden. Z. T. war »nur« unser batman-adv-DKMS (Kernelmodul) ausgetauscht, aber noch kein Reboot erfolgt, z. T. der Server aber auch schon rebootet worden und mit dem inkompatiblen batman-adv-Modul gestartet, wie im Folgenden gw01-neu:

gw01 wurde zwar im Syrtaki schon neu gestartet, aber es fehlten Einträge in /etc/rc.local

Morgen wird noch weiter geprüft/aufgeräumt, u. a. die Einbindung von gw01 ins Mesh (sollte nicht über fastd sondern lokale Tunnel/das neue batman-VLAN laufen …).
