Hello I'm quite new to pdns, used bind before for ages :-)
I wonder if the following would be possible with a LUA script in pdns recursor: I enforce quite low TTL on pnds-rescuror and dnssec validation is on. The low TTL makes me headache for queries to check if a domain is dnssec enabled at all. As most of them are not those negative answers are cached with the low TTL, therefore my pdns-resursor makes unnessecary queries. So I wondered if I could use a LUA script to manipulate the TTL for just those negative answers to higher TTL in cache. That way the amount of unnessecary queries would be reduced. I'm aware that enforce low TTL in first place might be against RFC but in my use case I need the low TTL (mostly) :-) Thanks for any help/idea tobi _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users
