[Pdns-users] DNSSEC error

[Huber, Peter]

Thank you, I understand, that our server is not authoritative for .de. bur it seems our zone is no longer signed, but it was signed in the past. Do I have to resign uni-wh.de? How can this disappear?


dig @127.0.0.1 dmz6.uni-wh.de. rrsig

i have strange thing using the pdns resolver. My domain uni-wh.de was ok for a long time, now there seems to be a DNSSEC problem and I don’t know where this comes from, nor how to fix this.
What I am testing:

delv @193.175.243.110 uni-wh.de

You say the problem is with a "pdns resolver", but 193.175.243.110 is an authoritative server, not a recursor.
From the error output you gave, it looks like you're using a tool which wants to talk to a recursor:
;; chase DS servers resolving 'uni-wh.de/DS/IN': 193.175.243.110#53
;; REFUSED unexpected RCODE resolving 'de/NS/IN': 193.175.243.110#53
;; REFUSED unexpected RCODE resolving './NS/IN': 193.175.243.110#53
;; REFUSED unexpected RCODE resolving 'de/DS/IN': 193.175.243.110#53

Your authoritative server is (correctly) refusing to answer queries for domains it is not authoritative for, like ".de" and the root.

There are various online DNSSEC checkers. I checked a couple with uni-wh.de and they seem to think it's fine (and I can resolve it fine), so I don't think there's any problem.
