Thanks for the answer but:
You say "Don't use forwarding from a recursive server to a
non-recursive server" but when my server1 is recursive (and the
firewall allow it to contact the outside), and server2 don't
recurse because in it's conf recursion is set to no, when i ask my
server1 about ftp.example.com <ftp://ftp.example.com> (dig @0
ftp.example.com <ftp://ftp.example.com>) , server1 forward the
query to server2 which answer by the CNAME www.abc.com
<http://www.abc.com> and then server1 recurse to find the IP of
www.abc.com <http://www.abc.com>. and everything works fine.
And my question is always this:
forward only; as i read means a recursive query, in other term a query
with the RD bit is enabled. which means that when my server1 (which has
recursion yes but can't recurse because the firewall don't allow it to
contact the outside, which finally means server1 can't recuse) ask
server2 about ftp.example.com <ftp://ftp.example.com>, server2 will
normally make all the work means he read on it's zone, then find the
CNAME, then make a recursion to resolve the CNAME and finally send the
IP to server1.
why server2 don't recurse to find the IP of www.abc.com?
thanks for your help.
Because you told it not to "> server2 don't recurse because in it's conf
recursion is set to no"
