[Pdns-users] wildcards and pipe backend

[Fagyal Csongor]

Hi,

I am in the middle of migrating from BIND to PowerDNS using pipebackend, 
and I have run into some trouble.

----
First, wildcard records.

Say, I have the following records:

foo.example.com   IN   CNAME   1.2.3.4
*.example.com   IN CNAME   1.1.1.1

Obviously
dig foo.example.com should return 1.2.3.4
but
dig bar.example.com should return 1.1.1.1

The question is: if I know I have wildcard records, then I have to do a 
wildcard query? Currently what I do is to first query non-wildcard 
records, and if none is found, then I do a wildcard match. Is that 
correct? Do the backend have to know about wilcrads at all?

----
Second: AXFR.

I often get AXFR queries from pdns, which look like "AXFR 1".
What zone should I return in this case?

What I do now is to store the last domain queried, and when an AXFR is 
received, I send out the zone according to that last domain. Is this 
correct?


Thanks,
