Primary DNS and Secondary DNS

[ramesh_6]

Hi all,

I have two different networks and two different scenarios for configuring DNS.

First Network and First Scenario:

I have a SUN Netra Server and a Windows NT(high config) Server. Presently SUN Server is the Primary DNS Server.

My Question: I want to make Windows NT Server as the secondary DNS server.

1) IS it possible?
2) Is there be any issues with regard to cross-platforms?


Second Network and Second Scenario:

I have a HP-UX Server as primary DNS Server. I have a spare SUN Ultra server with Solaris 8.

My Question: I want to make Sun Solaris Server as the secondary DNS server.

1) IS it possible?
2) Is there be any issues with regard to cross-platforms?


IF possible Can you experts give me some suggestions on how to do it?

Hi Ramesh,
I don't know much about NT. But it is possible.

HP - Sun no problem. We have exact same configuration. HP is master and SUN is secondary server. I am assuming that you are using bind 8.x on HP. Install bind 8.x on SUN.
Create named.conf file in /etc/. If you have BIND 4.X then use
#/usr/sbin/named-bootconf.pl /etc/named.boot > /etc/named.conf
This will create new named.conf using your named.boot file.
vi /etc/named.conf. Change directory to appropriate location.
options {
check-names master ignore;
check-names slave ignore;
directory "/usr/local/named";
};
change the servers if they are different.
So it looks like

zone "movie.com" {
type slave;
file "sec.hosts.movie.com";
masters {
10.10.10.1;
};
};
/* 10.10.10.1 is HP server */
And so on......

Restart the named and you will have all your map pulled from HP server

Hi, it has been a while since I tried this, so I do not remember the specifics, but when I tried to mix NT DNS servers with HP-UX or Free BSD DNS servers they did not get along well at all. I recommend the Sun/HP combination or an all NT, heresy, DNS server configuration. Hope this helps.

Both scenarios are possible. But assuming you are running BIND on both HP and SUN then you should have very few (if any) problems there. Microsoft's DNS is not using the same standards as BIND (surprise, surprise), so certain things do not work the same way (dynamic updates, forwarding zones, security, etc). If the DNS is real basic, then the 2 should be able to work together.
Definitely get a copy of DNS and Bind 4th Edition from O'Reilly

Good luck.
