[Pdns-users] Adding a caching nameserver to an existing secondary DNS server

[Nils Breunese (Lemonbit)]

Hello,

We have a machine that runs PowerDNS as a slave for a couple of  
supermasters. The same machine also functions as a backup MX. I'd like  
to add a caching nameserver to this machine to decrease the time  
needed for DNS lookups, just for use by localhost. How would I set  
this up? Do I install the PowerDNS recursor? Do I need any special  
configuration because the PowerDNS setup we're already running?

Thanks,

Nils Breunese.
