[Flushing Cache] Resolver and forwader

[Jeremy Mauro]

A weird problem for me:
I have a resolver that caches the DNS requests (Normal) that also
forward to some external resolvers with the option "forward only"

Everything works, except that:
$rndc reload
rndc: connection to remote host closed
This may indicate that the remote server is using an older version of 
the command protocol, this host is not authorized to connect,
or the key is invalid.

And I used the tool "rndc-confgen" to create the rndc key. So it is not
a key problem.

Any idea?
I thing it is a problem due to the "forward only" as if the resolver
tried to connect to the forwarder

----
$ cat rndc.conf 
# Start of rndc.conf
key "rndc-key" {
        algorithm hmac-md5;
        secret "OPIRd5KCXXXXX";
};

options {
        default-key "rndc-key";
        default-server 127.0.0.1;
        default-port 953;
};
# End of rndc.conf

$ head -20 named.conf

 key "rndc-key" {
       algorithm hmac-md5;
       secret "OPIRd5KXXXXX";
 };
 
 controls {
       inet 127.0.0.1 port 953
               allow { 127.0.0.1; } keys { "rndc-key"; };
 };
