Ubuntu – multiple domains on bind9 nameserver; one is not working

binddomainnameserverUbuntu

Bind9 DNS sever

I have problem with setting up my dns server and another domain under it.

First I have my master domain set up as a ns1 name server and it works.

I need to add another domain which will use the ns1 name server. And when I set up it in my domain registrator with ns1.xxx ns2.xxx ns3.xxx (where ns2 and ns2) are slave name servers from free name server provider.

my /named.conf.local

zone "xxx.pl" {
        type master;
        notify yes;
        allow-transfer {
                zz.zz.zz.zz; 
                yy.yy.yy.yy; 
                kk.kk.kk.kk; 
        };
        file "/etc/bind/domains/xxx.pl";
};

zone "xx.xx.xx.xx.in-addr.arpa" IN {
        type master;
        file "/etc/bind/domains/xxx.pl.rev";
        allow-update { none; };
};

zone "yyy.pl" {
        type master;
        file "/etc/bind/domains/yyy.pl";
        allow-update { none; };
};

my /domains/xxx.pl

$TTL            86400
$ORIGIN         xxx.pl.
@       IN      SOA     ns1.xxx.pl. postmaster.xxx.pl. (#times etc);

@       IN      NS      ns1.xxx.pl.
@       IN      NS      ns2.xxx.pl.
@       IN      NS      ns3.xxx.pl.

@       IN      A       xx.xx.xx.xx
ns1     IN      A       xx.xx.xx.xx
ns2     IN      A       yy.yy.yy.yy
ns3     IN      A       zz.zz.zz.zz

@       IN      MX 10   mx
mx      IN      A       xx.xx.xx.xx

www     IN      A       xx.xx.xx.xx

so till this point it seems to be fine, at least I think so 😉

but when I need to add a new domain there is some kind of problem. I tried to look for something, but whenever I change anything I doesn't affect it at all.

my domains/yyy.pl

$TTL            86400
$ORIGIN         yyy.pl.
@       IN      SOA     ns1.xxx.pl. postmaster.xxx.pl. (#times etc);

@       IN      NS      ns1.xxx.pl.
@       IN      NS      ns2.xxx.pl.
@       IN      NS      ns3.xxx.pl.

@       IN      MX 10   ns1.xxx.pl.

@       IN      A       xx.xx.xx.xx
www     IN      A       xx.xx.xx.xx

my domains/xxx.pl.rev

$TTL            86400
$ORIGIN         xx.xx.xx.xx.in-addr.arpa.
@       IN      SOA     ns1.xxx.pl. postmaster.xxx.pl. (#times etc);

@       IN      NS      ns1.xxx.pl.
@       IN      NS      ns2.xxx.pl.
@       IN      NS      ns3.xxx.pl.

xx.xx.xx.xx.in-addr.arpa      IN      PTR     ns1.xxx.pl.

So domain xxx.pl works good but domain yyy.pl doesn't work at all I cannot even ping it.

Thanks for any clues, and if anyone keen to look at it I can pass more info.

//edit

I updated the config files and now I can dig on the yyy.pl domain

;; QUESTION SECTION:
;yyy.pl.            IN  A

;; AUTHORITY SECTION:

//edit updated and this configuration works as far as I'm aware, thanks for help!

The incorrect A record in yyy.pl is most likely the reason why that zone is not working. A quick check of the logs should show it rejecting that line of the file. A records should be an IP address not a hostname.

There's also quite a few missing dots off the end of some of the entries. Remember that for fields that take a hostname, a missing dot on the end means it'll add the origin. In the case of yyy.pl for example, the missing dot on the MX record will make that ns1.xxx.pl.yyy.pl.

I guess MX records will porbably work in a reverse zone but I can't see you needing it.

Also the PTR line is missing dots. Following the logic above it's actually adding a record for the following:

xx.xx.xx.xx.in-addr.arpa.xx.xx.xx.xx.in-addr.arpa.      IN      PTR     ns1.xxx.pl.xx.xx.xx.xx.in-addr.arpa.

Edit: There's also a $ missing from the TTL setting in yyy.pl
