Cannot figure out DNS Master Error:

Question

I am attempting to use zone transfer between my Master and Slave DNS servers however I am unable to start my named service and receive the following error:

[root@balsam named]# systemctl status named.service

What does this mean? I can't seem to figure it out.

Here is the zone files its mentioning:

mydb-for-172.30.20

$TTL    3D
@       IN      SOA     balsam.coniferous.trees.ops.      pine.coniferous.trees.ops.(

                8H      ; Refresh
                2H      ; Retry
                1W      ; Expire
                1D      ; Negative Cache TTL
);
@           IN      NS      balsam.coniferous.trees.ops.
1           IN  PTR larch.coniferous.trees.ops.
2           IN      PTR     balsam.coniferous.trees.ops.
3                       IN      PTR     spruce.coniferous.trees.ops.
5                       IN      PTR     pine.coniferous.trees.ops.
6                       IN      PTR     fir.coniferous.trees.ops.
8                       IN      PTR     bristlecone.coniferous.trees.ops.
5           IN  MX  pine.coniferous.trees.ops.

and the other one mydb-for-ajfoncec-org

$TTL    3D

                2H      ; Retry
                1W      ; Expire
                1D      ; Negative Cache TTL
);
@       IN      NS      vm1.ajfoncec.org.
vm1     IN      A       192.168.62.2
vm2     IN      A       192.168.62.3

oh and the mydb-for-coniferous-trees-ops

$TTL    3D

                1W      ; Expire
                1D      ; Negative Cache TTL
);
@       IN      NS      balsam.coniferous.trees.ops.
balsam  IN      A       172.30.20.2

Delete this line from below PTR records:

5           IN  MX  pine.coniferous.trees.ops.

Firstly, reverse zones don't need MX records, no one will be sending an email to such address. Secondly, it's malformed.

Your MX record for pine.coniferous.trees.ops. lacks the priority number. And it's useless to begin with, this is a reverse zone.

Please take the time to read error messages and to think about them....

There might be further errors, but I've stopped reading at the first error message. Check your files again.
