[Pdns-users] positive cache-ttl on recursor

[Marten Lehmann]

Hi,

I'm about to migrate from BIND named caching daemon to pdns-recursor, 
but I cannot find an equivalent for BINDs max-cache-ttl option.

While max-negative-ttl in pdns is the same as max-ncache-ttl in BIND, I 
cannot find an analog parameter for max-cache-ttl. Parameters that I 
found in different search results (ie. cache-ttl or packet-cache-ttl) 
seem to relate to the authoritative pdns only.

pdns-recursor is only used locally on several servers and as dns entries 
for our internal stuff and customer configurations might change more 
often then IPs of google.com, we want a positive cache ttl of 900, no 
matter what the authoritative dns told. How can we do this?

Kind regards
Marten
