[Pdns-users] Resolving external cname's

[Alexandre NEY]

Hello Steve and thank you for your answer.

 

Unfortunately, this change in the config does not solve my problem, i still
get a NXDOMAIN answer when i query a A entry which points towards an
external CNAME.

Add "root-referral=lean" to your pdns config file.

Hello pdns users :)

I'm sorry to redig this problem but doesn't anyone resolve external CNAME's
here ?

http://osdir.com/ml/network.dns.powerdns.user/2007-08/msg00035.html

seems to have the same problem but I did configure my recursor and when
querying directly the CNAME i get an answer.

I have just tried with Microsoft DNS and BIND and I don't experience this
behavior, only with PDNS.

I'd really like to use pdns instead of bloatted bind but not being able to
resolve external cname's is a real show stopper for us.

Any advice anyone ?

Thanks !

Alex

Hello Simon,

It was actually pointing towards CNAME (we used www.google.com for our
tests) but even with a A field we have the same problem.

So we have something like this :

www3.example.com CNAME something-else.com
something-else.com A xxx.xxx.xxx.xxx

Thanks !

Is www.somewhere-else.com a CNAME as well? We experienced an issue with a
CNAME pointing to a CNAME not functioning - I am not sure if this is by
design and due to rfc's but took us a short while to figure out and may
assist you as well.


With best wishes
