Forwarding problems and lame NS

[Hubert.QUARANTEL at DSI.VLY.sextant.thomson-csf.com]

Hi,

	I finally found what was the reason of the "skipping lame NS "
problem... dns.ENTERPRISE.GROUP.com was running bind 8.2 with an invalid
config file due to syntax errors... I do apologize...
	But I still have another problem:
		at th efirst time I ask dns.PARIS.ENTERPRISE.GROUP.com any address in
GROUP.com everything works perfectly in term of recursion/forwarding,
but at the second time dns.PARIS.ENTERPRISE.GROUP.com tries to contact
directly nameservers of GROUP.com it as cached IP adresses, despite of
the "forward only" directive...

options {
        has-old-clients yes;
        auth-nxdomain yes;

        check-names master warn;
        notify          no;

        recursion yes;
        forward  only;
        forwarders {AAA.BBB.CCC.DDD;};

        directory       /dns;
};

zone "."        in {
        type    hint;
        file    "db.cache";
};

zone    "0.0.127.IN-ADDR.ARPA"  in {
        type    master;
        file    "db.127.0.0";
};

zone    "PARIS.ENTERPRISE.GROUP.com"   in {
        type    master;
        file    "db.PARIS";
};

zone    "CCC.BBB.AAA.IN-ADDR.ARPA"         in {
        type    master;
	file	"db.AAA.BBB.CCC";
};

I had to hide real IP addresses and real names because of the Network
Security Agents...

dns.PARIS.ENTERPRISE.GROUP.com is only authoritative for
PARIS.ENTERPRISE.GROUP.com
and so on for city nameservers

and dns1.ENTERPRISE.GROUP.com is authoritative ofr ENTERPRISE.GROUP.com

> What do the NS records for Enterprise.group.com look like?

things like
	PARIS				IN	NS	dns.PARIS.ENTERPRISE.GROUP.com
	dns.PARIS.ENTERPRISE.GROUP.com	IN	A	AAA.BBB.CCC.DDD
	LONDON				IN	NS	dns.LONDON.ENTERPRISE.GROUP.com
	dns.LONDON.ENTERPRISE.GROUP.com	IN	A	AAA.BBB.EEE.FFF

yep !

named complains about "no root nameservers found..." if the cache file
is empty or if I disable the hint zone... but on the other hand, if
GROUP.com nameservers are mentioned in the cache file named ignores the
forwrading directives...

	Now, the problem seems to be that named just ingores the
recursion/forwrd directives, and i can't figure out why ???

thanx to everybody feeling concerned, I do sincerely apprecieate your
help...
