+ | dnssec-keygen -a 7 -b 2048 -n ZONE domena.org | ||
+ | dnssec-keygen -f KSK -a 8 -b 4096 -n ZONE domena.org | ||
+ | |||
+ | copy generated files in / | ||
+ | |||
+ | if you put your keys in / | ||
+ | |||
+ | |||
+ | put this in zone domena.org | ||
+ | |||
+ | inline-signing yes; | ||
+ | auto-dnssec maintain; | ||
