Hi, We are in the process of migrating from bind-9.4-ESV-R2 to bind-9.7.2-P2.
We have our authoritative servers migrated to bind-9.7.2-P2 and it all seems to work fine. While testing our caching resolvers with bind-9.7.2-P2 however, we noticed some errors in our logfiles we have never seen before. Oct 26 09:52:03 myhost named[21085]: DNS format error from 1.5.3.4#53 resolving 1.2.4.2.x.y.z.example.com/TXT for client 1.5.3.203#15637: non-improving referral Oct 26 09:52:03 myhost named[21085]: DNS format error from 1.5.2.2#53 resolving 1.2.4.2.x.y.z.example.com/TXT for client 1.5.3.203#15637: non-improving referral Obviously I have obscured some data here :) As you may guess this is a query for a TXT record from a blocklist-daemon. The nameservers on 1.5.3.4 and 1.5.2.2 are bind-9.7.2-P2. The queried domains are hosted by us and the hopefully relevant part of the zone looks like this: x.y.z.example.com. IN NS bl1a.example.com. x.y.z.example.com. IN NS bl1b.example.com. A dump of the cache shows NS and A records are in the cache for bl1[ab] however, on each non-cached query from the client both errorlines are printed in the log suggesting the resolver is not using the cached NS records. The client receives a valid answer, so my only real problem seems to be the amount of spam I get in our logfiles. The blocklist is served by rbldnsd, manually query-ing gives my a valid response. Could anybody tell me what problem bind is complaining about? Please CC me as I am not on this list. -- Leo Baltus, internetbeheerder /\ NPO ICT Internet Services /NPO/\ Sumatralaan 45, 1217 GP Hilversum, Filmcentrum, west \ /\/ beh...@omroep.nl, 035-6773555 \/ _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
