Hostname dieses Nameservers

• In den Dateien verwende ich pins als Hostname für diesen Nameserver

Uhrzeit-Problem

• Der Rapsberry Pi hat keine Hardware-Uhr, das ist bei bind9 problematisch, da DNS-Server im Internet befragt werden und dazu zeitabhängige Schlüssel verwendet werden
• Ist die Uhrzeit hierbei falsch (zum Beispiel nach einem 3 stündigen Stromausfall) wird sich also der lokale DNS Server weigern Antworten aus dem Internet zu akzeptieren, der Dienst fällt dann für das lokale Netz aus
• Somit sollte man per ntp !!!OHNE NAMENSAUFLÖSUNG!!! einen Zeitserver kontaktieren und erst mal die Uhr stellen, dann kann man den bind9 starten

• ... die muss noch erledigt werden

/etc/resolv.conf

• Lokale DNS Anfragen soll der eigene Server beantworten

# 
# Ich bin Nameserver
#
nameserver 127.0.0.1
domain lummerland
search lummerland

• Ev. die Datei durch attrib +i resolv.conf vor überschreiben schützen
