Re: [Pdns-users] Configure PowerDNS recursor as NON RECURSIVE
Hi Adriel Torres, Thanks for the reply. I am aware that it has two packages but I am wondering if I could configure the pdns-recursor stand alone to work as non-recursive? I guess I can not. Also could you please tell in brief how does the pdns-server (PowerDNS Auth Server) works exactly? I am confused after reading so many things on internet. Thanks.

That is correct the only purpose of PowerDNS recursor is to act as a recursive nameserver. Although it has been fitted with the ability to serve static zones (see the forward-zones configuration statement [1]), it does not have a switch to globally disable recursion.

PowerDNS Server (!= recursor) features lots of backends therefore you first need to tell it which backend to fire up and use. [2] The most commonly used is probably the gmysql backend. In order to serve the data from a mysql database you first need to create some tables. [3] PowerDNS Server configuration usually resides in the /etc/powerdns/pdns.conf file. For a simple mysql backend configuration one would put something like the following in there: launch=gmysql gmysql-host=127.0.0.1 gmysql-dbname=mydatabase gmysql-user=pdns gmysql-password=secret However if you are already familiar to the way BIND is doing things maybe you want to do your first steps into PowerDNS land with the bind backend. [4] That would be something like: launch=bind bind-config=/etc/namedb/named.conf - or where your named.conf is situated The bind backend will simply iterate through the zone statements in named.conf and load all zonefiles specified there.

Re: [Pdns-users] Configure PowerDNS recursor as NON RECURSIVE
Hi Stefan, Thanks for reply. It helped a lot to clear my confusion. I still have a question regarding pdns-server. How does it perform the query lookup? For eg: I query for host google.com 127.0.0.1 ... if this entry is in the database .. it returns the answer from database look up. But if the entry is not in the database and pdns-recursor is configured, it will perform the recursive lookup and return the answer. But what if pdns-recursor is not configure ? At this time I am working on configuring the pdns-server, hope I get it correct. Thanks.
