Bind Zone Transfer

dafunk · 03-20-2006, 04:53 PM

Hi Guys,

Ive just finished setting up my Primary and Secondary DNS, both running Debian 3.1
Primary = 192.168.1.69
Secondary = 192.168.1.3

How do I go about setting up automatic zone transfers from the Primary to Secondary DNS? At the moment, I need to manually create Zones on both servers.

Anyone able to help?

Uh, post your .conf's for each one. Provided the slave knows the IP of the master (or the hostname), it should transfer.

You also have to put "allow-transfer {ipofslave;};" in your master BIND server's .conf file.

Heres my conf files:

Primary:

options {
directory "/var/cache/bind";
allow-transfer { IP of secondary; };
#auth-nxdomain no; # conform to RFC1035

#forwarders {
192.168.1.3;
};
#max-transfer-time-in 1;
#transfer-format many-answers;
};

Secondary:

options {
directory "/var/lib/named";
dump-file "/var/log/named_dump.db";
statistics-file "/var/log/named.stats";
notify no;
allow-query { IP Of Primary; };
one "." in {
type hint;
file "root.hint";
};

zone "localhost" in {
type master;
file "localhost.zone";
};

zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0.zone";
};
include "/etc/named.conf.include";

You didn't show us how you define a zone in your secondary named.conf. Anyway for every zone you should have:

Code:

zone "domain.com" {
        type slave;
        file "domain.com";
        masters {xx.xx.xx.xx;};
};

Ok, so if I add that for each of the zones from the primary to the secondary, how does that make the primary send records to the secondary for all new zones created on the primary dns?

In the "masters" line, do I put the ip of the master dns server?

You must define the zones in both named.conf files for primary and secondary dns (using the keyword: "type master;" and "type slave;" respectively). Then it's the primary's job to inform the secondary for any changes made in a zone record.
And yes in the masters line you must put the IP of your primary dns

I'm not trying to be a jackass, but what material have you read about stuff like this?

If you get a chance, get the DNS and BIND book from O'Reilly. It explains a lot of this stuff. It's even got some really great information on setting up some really cool things like round robin, dynamic DNS, and other cool junk.
