Bind's handling of lame nameservers

2014-12-16 Thread John Wobus
How do BIND caching servers handle received responses with no aa flag? We're running BIND 9.9.6-P1 and I received a report of a query that our server sometimes answered as expected and sometimes didn't. The offending name is not one we are authoritative for. I checked the offending name and

We tried to check aa for just this reason but there are to many broken authoritative servers which just don't set aa=1 on all the servers for the zone that we had to back the code change out. I would just use a server clause to mark nameserver as bogus. Mark -- Mark Andrews, ISC 1 Seymour St.,

Thanks for the quick reply John, I answered some of the items in-line Hi John, First things first, some more info on your overall DNS infrastructure and how the 9.3.2 server fits in would be helpful. - Is this for education.ucsb.edu, other zones, or both? The NS is ONLY for

Thanks for the response, John. Helps a bunch to know that you just have the single zone to worry about. I also did a quick dig on education.ucsb.edu (NS SOA records). Looks like you're not running any of your own slaves, but are making use of two main university servers as slaves: ns1.ucsb.edu
