1. I don't see how to run both concurrently on the same host as they always<br>
conflict on the IP. The host has a singe address - 192.168.40.252.<br>

You cannot run two services of any kind on a single IP address, so<br>
running two DNS servers on one address won't work. See if you can put<br>
one of the servers on a loopback address, and the other on your public<br>
IP.<br>

in any case, its not really a good idea to have your recursor and authoritative DNS servers on the same host... however, to add onto Jan-Piet Mens comment, a cheap and dirty way to accomplish this would be to assign a virtual interface to your primary NIC with another IP, then assign the authorative server to use it, with the recursor setup on the 'real' interface open to the world...... then use the "forward-zones-recurse=" function on the recursor to foward queries to the 'virtual IP addressed' authoritative server. obviously there will be cons to using this setup, and isnt advisable to use this in a live environment (best to have two physical NIC's with seperate public IP's that listen and respond to request individually for each server).<br>

However, coming from BIND, my mind is transfixed with the single daemon which can do both authoritative and recursion (selectively). Does it mean that with pdns, I have to run at minimum THREE separate servers - one master, one slave, one recursor?<br>
<br>One other question I asked was why I am not able to resolve queries for domains hosted by my ISP. With BIND (sorry to always refer to it) running cache-only on my machine, things work fine.<br><br></div></div><br><br clear="all">
