Hi!
I have notice a litte strange behavior with FreeBSD + Bind 8.2.2patch7 (
same thing with p5 ) and the "allow-recursion" fuction.
Example :
TestServer1 running FreeBSD 3.3-stable
TestServer2 running FreeBSD 3.5-stable
TestServer3 running BSD/OS 4.1
TestServer4 running Linux
All running bind 8.2.2patch7 with the same config files, and just started
so nothing is really been cached yet.
When from a host that isnt allowed to ask a recursive query , query for
example www.foo.bar i only get the NS for the root server ( which is
correct )
Then asking about www.foo.bar from a allowed host will return in a A
record ( or whatever )
And now the diffrens in the behavior comes :
When again asking from the host that isnt allowed on :
TestServer1 and TestServer2 will answer with the A record ( or whatever )
that it now have cached. (not correct behavior(?))
TestServer3 and TestServer4 will only answer with the root nameservers
(correct behavior(?))
Anyone got a clue on why Bind under FreeBSD acts this way? and are there
any other OS=B4s that has the same behavior.
Best regards
Michael
