slaves/my.ddns.internal.zone.db:1: no TTL specified; using SOA MINTTL instead
zone my.ddns.internal.zone/IN: loaded serial 1
zone my.external.zone/IN: loading master file my.external.zone.db: file not found

Usually most distros these days come with DNS server already set up in a chroot jail. This means the service has it's own subset of the system outside of which it cant read.

You've probably got your links or paths to your domain's zone files pointed to places that dont exist in the chroot.

I suggest you go down the configured paths for your DNS domain and confirm that they point at the files and directories you expect.

Can you just paste your db file configuration here i thnk u missed TTl value in that or u have just missplaced it ..

my.internal.zone.db:1: no TTL specified; using SOA MINTTL instead
zone my.internal.zone/IN: loaded serial 1
slaves/my.ddns.internal.zone.db:1: no TTL specified; using SOA MINTTL instead
zone my.ddns.internal.zone/IN: loaded serial 1

The above messages are telling you that you did not configure your zone TTL's and it is going to use the minimum times for TTL's.

The zone TTL's are located at the top of the zone, i.e.

$TTL    86400 ; 24 hours could have been written as 24h or 1d
$ORIGIN example.com.
@  1D  IN     SOA ns1.example.com.    hostmaster.example.com. (
                  2002022401 ; serial
                  3H ; refresh
                  15 ; retry
                  1w ; expire
                  3h ; minimum

zone my.external.zone/IN: loading master file my.external.zone.db: file not found
external/my.external.zone/IN: file not found

This message is telling you that Bind cannot find the file you have configure in its configured directory. You should look at a few things here to figure out where you need to place my.external.zone file

in named.conf look at the following lines to determine where the file should be placed

options {
  directory "/var/named"

This statement tell bind where its working directory is. in this case it's /var/named but if your system is running Bind in a chroot env then the real path is /var/named/chroot/var/named

You should also look at your zone definitions to ensure that they don't point Bind to another directory for the zone files. The file option is what you should be looking at.

zone "example.com" in{
  type master;
  file "master/master.example.com";
  // enable slaves only
  allow-transfer {192.168.23.1;192.168.23.2;);
};

In the above config it is telling Bind to look in the master directory for the file. This is really /var/named/master and if you are using the chroot env then it is the same as above with master at the end.

Here is a link you could read for more information.
If you like a book in the hand then I would highly recomend this O'Reilly book.

Should you any more question please let us know.

[pratapsingh]

zone "example.com" in{
type master;
file "master/master.example.com";
// enable slaves only
allow-transfer {192.168.23.1;192.168.23.2;
};
"master/master.example.com" Rename this file and
name of this file should be like this "master.example.com.db" and create it under /var/named/ directory

c ontent should be like this

$TTL 86400 ; 24 hours could have been written as 24h or 1d
;$ORIGIN example.com. ; do not use this untill unless you dont know what is ;the use of this ..
@ 1D IN SOA ns1.example.com. hostmaster.example.com. (
2002022401 ; serial
3H ; refresh
15 ; retry
1w ; expire
3h ; minimum
)


And your serial number seems to be too big try to use small numbers ..
still if you still facing any issue please paste it here again i will try to resolve

The above you have referenced is from an example config not the real thing.

The file name you use can be anything you want to call it. it doesn't have to end in db.

The serial number it is perfectly fine and is not too big. Allow me to explain.

2002022401 ; serial is broken down as follows;

2002 = year
02 = month
24 = day
01 = number of changes that day.

This is used for auditing purposes and is followed by many.
