BIND8 to BIND9 anomaly

[Bob Vance]

I just noticed a mild quirk of going to BIND 9.1.1.

On a test server, running 8.2.3-rel, I had an empty root hints file, at
least it was nothing but comments.
Since I'm using forwarders, I don't care about root servers.

Anyway, BIND8 didn't mind and loaded and worked fine, answering his own
zones authoritatively and forwarding for the rest.

pluto# dig www.yahoo.com

would return correct data.


But, when I loaded BIND 9.1.1, the
    'dig www.yahoo.com'
refused to forward, returning a SERVFAIL error.
I could do a
    'dig www.yahoo.com @<forwarder>'
just fine and 'named' still answered it's own stuff authoritatively.


I set debug level to 100  ( :)  but there was nothing mentioned about a
hints problem and all that is logged on the request is a simple
   "error"
:{
in the client attach logic:

security: debug 3: client 127.0.0.1#2001: recursion approved
client: debug 3: client 127.0.0.1#2001: query
client: debug 10: client 127.0.0.1#2001: ns_client_attach: ref = 1
security: debug 3: client 127.0.0.1#2001: query approved
====here========================================
client: debug 3: client 127.0.0.1#2001: error
====here========================================
client: debug 3: client 127.0.0.1#2001: send



Anyway, I just removed the "hints" zone and that fixed the problem.

I also tried adding some trash to the cache file:

.       99999999    IN  NS  root.server.
root.server.    99999999    IN  A   1.2.3.4


and that also worked !!!!
