[Pdns-users] pdns recursor forward zone to consul

[prochazka at cortex.cz]

Hi,

CZ domain is signed by CZNIC, but cortex.cz and it's subdomains aren't 
signed. We don't use lua yet so i tried to set "dnssec=off" and it's 
done = working.

This come to second question. Consul returns ttl 0, dnsmasq returns by 
default ttl 0 too. Recursor returns with ttl 3600, those are unchanged 
defaults:

# max-cache-bogus-ttl	maximum number of seconds to keep a Bogus 
(positive or negative) cached entry in memory
# max-cache-bogus-ttl=3600
# max-cache-ttl	maximum number of seconds to keep a cached entry in 
memory
# max-cache-ttl=86400
# max-negative-ttl	maximum number of seconds to keep a negative cached 
entry in memory
# max-negative-ttl=3600
# minimum-ttl-override	The minimum TTL
# minimum-ttl-override=1

So it's handled with max-cache-bogus-ttl? And setting it per domain will 
require lua?

Thanks
Martin Prochazka
