Hi,
i have a server called server1 that is acting as a cache server( recursion
none). And i forward the zone example.com to server2 which has recursion
enabled and master on some zone like example.com.
this is the forwarding zone on server1:
zone "example.com" {
type forward;
forward only;
forwarders { IP_of server2; };
};
and server2 is master of the zone example.com:
zone "example.com" {
type master;
file "master/db.example.com";
};
BUT the problem is here:
db.example.com:
....
$ORIGIN example.com.
www A 1.2.3.4
ftp CNAME www.abc.com<http://www.abc.com>
server1 can resolve www.example.com<http://www.example.com>, but can't resolve
ftp.example.com<ftp://ftp.example.com> since the server2 sends the answer which
is www.abc.com<http://www.abc.com> and not the IP, and my server1 can't make
recursion to resolve www.abc.com<http://www.abc.com>.
why?
from server1 when i dig on server2: dig @IP-server2
www.example.com<http://www.example.com> it sends to me the IP, all is OK!!! but
with a forwarding statement it sends only the CNAME
server1 is bind9.6-ESV-R4 et server2 bind-9.4.2
Thanks.

Objet : Re: forward first: iterative or recursive query
With a static-stub zone, you would get an iterative query. Forwarding always
results in a recursive query.
How are you determining that your server is sending an iterative query?
Can we (the list) see your named.conf?

Hi
from the book DNS and Bind 5th edition [french] (o'reilly)
I read that the forward with the mode first sends a recursive query to the
servers on the forwarders list, but as i see it only sends an iterative query.
Also with forward only it send an itérative query.
So forward first send an itérative or recursive query?
And how i can send a recursive query with the statement forward ( without using
static-stub)
I'm using bind-9.6-ESV-R4
Thanks.
