DNSSEC Schlüssel erzeugen

Forward Zone
  • dnssec-keygen -a RSASHA256 -b 2048 -n ZONE it2XX.int
  • dnssec-keygen -a RSASHA256 -b 4096 -f KSK -n ZONE it2XX.int

DNSKEY einbinden

Forward
  • for k in Kit2XX.int.+*.key ; do echo "\$INCLUDE $k" >> /var/cache/bind/it2XX.int; done

Zonen signieren

  • dnssec-signzone -A -N INCREMENT -o it2XX.int -t /var/cache/bind/it2XX.int
Erzeugt
/var/cache/bind/it2XX.int.signed
  • systemctl restart named
