[Slack] Problems with named

Hi,
yesterday I installed Slackware 10.1 on my homeserver. Before that, it was running Slack 9.0. I made a backup of all my config files (apache, samba, php, named, proftpd, ...) and copied them onto the new install. Everything works fine (after some minor adjustments in de config files), except for named.
It's weird actually: named does start without errors (and keeps running), but any local zone I cannot find.
Here are my config files:


/etc/named.conf:
Code:
options {
        directory "/var/named";
        pid-file "/var/run/named/named.pid";
        // Uncommenting this might help if you have to go through a
        // firewall and things are not working out.  But you probably
        // need to talk to your firewall admin.

        // query-source port 53;
};

controls {
        inet 127.0.0.1 allow { localhost; } keys { rndc_key; };
};

key "rndc_key" {
        algorithm hmac-md5;
        secret "KJLZX+44uYN7dTz5QuyKQw==";
};

zone "." IN {
        type hint;
        file "root.hints";
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "pz/127.0.0";
};

zone "maes.local" IN {
        type master;
        notify no;
        file "pz/maes.local";
};
/var/named/pz/maes.local:
Code:

;
; The full zone file

I also ran "named-checkconf /etc/named.conf", which doesn't return any errors or notices.
Pinging to "www.maes.local" from any machine (client or the server itself) does not work. Pinging to "www.google.com" works from all machines.

Did that as well, but can't see anything wrong:

Are you sure you're using the correct named.conf? Cause from the logs zone 0.0.127.in-addr.arpa is loaded (which does not exist in the named.conf you posted) and the zone maes.local is not loaded.

My bad: didn't copy-paste the whole file.
It does load the correct named.conf (did a search, is the only file on the whole system)
Edited first post.

your local zone file, maes.local, well i don't see it loading in /var/log/messages. why is it not loading? it you don't load it how would your query fetch data based on the records of that zone.

Yes ofcourse, I understand that.
What I meant was: what is wrong with my config that it doesn't load the zonefile?

like already said, i am not an expert. shouldn't there be a IN between those www|photos and 192.168.0.2? i don't know actually, maybe someone else knows.

You should add:
Code:
ns             A       192.168.0.2
in your zone file (/var/named/pz/maes.local) cause there is no entry for the host ns, so you cannot find your own dns.

It notifies other DNS servers of changes (I believe).

Anyway, just to be sure I removed the line and restarted named:
Code:
Aug  9 12:11:01 SUN named[1272]: starting BIND 9.3.0
Aug  9 12:11:01 SUN named[1272]: loading configuration from '/etc/named.conf'
Aug  9 12:11:01 SUN named[1272]: no IPv6 interfaces found
Aug  9 12:11:01 SUN named[1272]: listening on IPv4 interface lo, 127.0.0.1#53
Aug  9 12:11:01 SUN named[1272]: listening on IPv4 interface eth0, 192.168.0.2#53
Aug  9 12:11:01 SUN named[1272]: command channel listening on 127.0.0.1#953
Aug  9 12:11:01 SUN named[1272]: zone 0.0.127.in-addr.arpa/IN: loaded serial 1
Aug  9 12:11:01 SUN named[1272]: running
Aug  9 12:11:01 SUN named[1272]: zone 0.0.127.in-addr.arpa/IN: sending notifies (serial 1)
It doesn't load nor notify maes.local

Wasn't on previous install (as that worked).
Anyway, checked google, seems others add "IN" as well, so did it as well now.
Unfortunately it didn't make a difference

More information:
maes.local isn't the only domain I'm running on this server. Another domain on it is datanuke.be:
/var/named/datanuke.be
Code:
;
; Zone file for datanuke.be
;
; The full zone file

$TTL 3D

//                MX      20 mail.friend.bogus.   ; Secondary Mail Exchanger
;
localhost       A       127.0.0.1
www             A      213.193.229.20
2x              A       192.168.0.2
ftp             A       192.168.0.3
www.datanuke.be is a public website. All the others are sites on my local servers (for developement etc).

Although I can ping www.google.com on the servermachine (public IP), I fail to reach www.datanuke.be. This is interesting, because it means that named does "pick up" the request, but is unable to handle it.

My guess is the problem lies in the zone-files..

in my understanding, bind should look for maes.local and try to load it (even if it has errors), but since it isn't even trying, i feel it is not using the named.conf you have configured.
