====== openQRM - DNS ======

Damit das "RollOut"-Plugin funktioniert müssen wir noch eine "DNS-Abkürzung" (//svn//) bauen:

===== /usr/share/openqrm/plugins/dns/etc/bind/zones/extra.db =====

  $TTL            3600
  @               IN      SOA     ns.oqrm.victorvox.net. root.ns.oqrm.victorvox.net. (
                          2010093001 ; serial
                          3600       ; 1h  refresh
                          900        ; 15M retry
                          604800     ; 7d  expire
                          3600 )     ; 1h  minimum ttl
  
                IN      NS      ns.oqrm.victorvox.net.
  svn           IN      A       192.168.205.44

===== /usr/share/openqrm/plugins/dns/etc/bind/named.conf.local =====

  zone "oqrm.victorvox.net" IN {
          type master;
          file "/etc/bind/zones/oqrm.victorvox.net.in.db";
  };
  
  zone "5.10.10.in-addr.arpa" {
          type master;
          file "/etc/bind/zones/oqrm.victorvox.net.rev.db";
  };
  
  zone "extra" {
          type master;
          file "/etc/bind/zones/extra.db";
          notify no;
          check-names ignore;
  };
  
  zone "database" {
          type master;
          file "/etc/bind/zones/database.db";
          notify no;
          check-names ignore;
  };
  
  zone "extern" {
          type master;
          file "/etc/bind/zones/extern.db";
          notify no;
          check-names ignore;
  };

So, und zum Abschluss jetzt das "dns"-Plugin restarten (stop/start).

===== /usr/share/openqrm/plugins/dns/bin/openqrm-dns-manager =====

Leider bleiben bei jedem austragen eine Leerzeile übrig,
das ist auf Dauer sehr unschön.
Deshalb werden wir dem //sed// noch die Option "-e '/^$/d'" mitgeben:

=== alt ===

          ...
          stop)
                  dns_lock aquire
                  dns_log openqrm-dns-manager "Appliance $APPLIANCE_NAME id $APPLIANCE_ID stopping with ip-address $APPLIANCE_IP"
                  sed -i -e "s/$APPLIANCE_NAME.*.$APPLIANCE_IP//g" $DNS_INDB
                  sed -i -e "s/^$APPLIANCE_LAST_IP_BYTE *.*$APPLIANCE_NAME*.*//g" $DNS_REVDB
          ...
