Hi Folks,
I have a primary dns setup [rh9] inside my firewall. I would like to setup a secondary one on another system which is already running rh7.3. I've been reading about zone-transfers and stuff. I wanted to pass it by you folks; perhaps someone can tell me if I'm in the right direction.
I configured my main dns server quite some time ago, and I thought I read somewhere that in order to have a secondary dns server, it needed to be configured at the same time as the primary is being configured... I cannot find where I read this... is this accurate? Or can I configured a secondary dns when the first is already configured and running for quite some time.
I 've read that I need a named.boot file which would perhaps look like this on the 'secondary' server. I guess this file would go in /etc somewhere?
------------------
;
; me.com secondary nameserver boot file.
;
directory /var/named
secondary me.com p-dns-ipaddress-here somefilename-inside-var-named-folder
primary 0.0.127.IN-ADDR.ARPA named.local
cache . named.ca
------------------
Is this it? Run ./named and away I go? I noticed that on /etc/named.conf file, there are these entries:
...
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
...
include "/etc/rndc.key";My understanding is that this makes zone transfer more secure? The question is what are the implications when there's a secondary dns? Do I add the name/ipaddress of the secondary where "localhost" is?
I'll keep googling...
Thanks for any insights!
Rafael.
