|
|
+# Allgemein
|
|
|
+- Als Nameserver im weiteren NS genannt, kommen nsd und unbound zum Einsatz.
|
|
|
+Auf nordstadt und hoerde ist freeBSD im Einsatz, auf den APUs Debian.
|
|
|
+Durch die unterschiedliche Verzeichnisstruktur befinden sich die Konfigurationsdaten in verschiedenen Verzeichnissen:
|
|
|
+freeBSD: /usr/local/etc/nsd und /var/unbound
|
|
|
+Debian: nicht installiert und /etc/unbound und /var/lib/unbound
|
|
|
+
|
|
|
+ Überblick nsd ./. unbound:
|
|
|
+................nsd...................unbound
|
|
|
+nordstadt...193.43.220.129...193.43.220.161
|
|
|
+hoerde......130.180.53.22.....193.43.220.136, 193.43.220.168
|
|
|
+
|
|
|
+Zur Steuerung gibt es **nsd-control** und **unbound-control**. Bei freeBSD **local-unbound-control**.
|
|
|
+
|
|
|
+
|
|
|
+## Der primäre NS (nsd) auf nordstadt hält die aktuellen Zonendateien vor
|
|
|
+
|
|
|
+- ***ffdo.net*** für die Auflösung Name -> IP
|
|
|
+- ***220.43.193.in-addr.arpa*** für reverse mapping ip -> Name für 193.43.220.
|
|
|
+- ***221.43.193.in-addr.arpa*** für reverse mapping ip -> Name für 193.43.221.
|
|
|
+
|
|
|
+Die Dateien ffdo.net und xxx.in-adr-arpa sind unter den oben angegebenen Verzeichnissen in freeBSD und Debian zu finden.
|
|
|
+
|
|
|
+Die sekundären NS (nsd und unbound) erhalten diese Zonendateien vom primären NS.
|
|
|
+
|
|
|
+Die Zonendaten können mit
|
|
|
+ **nsd-checkconf** -p 220.43.193.in-addr.arpa 220.43.193.in-addr.arpa
|
|
|
+ **nsd-checkconf** -p 221.43.193.in-addr.arpa 221.43.193.in-addr.arpa
|
|
|
+ **nsd-checkconf** -p ffdo.net ffdo.net
|
|
|
+geprüft werden.
