[SOLVED] simple DNS server problem

vincix · 01-28-2014, 03:18 PM

I am trying to set up a simple DNS server in CentOS 6.5.
This is what my named.conf looks like:

Quote:

options {
listen-on { 127.0.0.1; 192.168.1.107; };
};

zone vinci.rr in { type master; file "/var/named/vinci.rr"; };

And this is my zone file "vinci.rr"

Quote:

$TTL 86400;
$ORIGIN vinci.rr.
@ IN SOA ns1 hostmaster.vinci.rr (
2014012801; serial
10800; refresh
3600; retry
604800; expire
86400; minimum
)
IN NS ns1 ; in the domain

ns1 IN A 192.168.1.107;
www IN A 192.168.1.107;
IN A 192.168.1.107;

Whenever I try to ping (from the host itself) vinci.rr, I get this error:

error (unexpected RCODE REFUSED) resolving 'vinci.rr.net/A/IN': 1.1.1.1 (-> there's a public ip there instead of the 1s).

What should I be looking for?

This means that you are not using your dns as a resolver and instead you're going out to the net and query the real authoritative name server for the rr.net.domain. The response you get from that nameserver is "REFUSED" due to its configuration.
In order to use your nameserver, edit /etc/resolve.conf and add it before any other nameserver

Your zone file is for the .rr TLD. Your query is in the .net TLD. The two do not intersect. Maybe you want to do a zone file for the domain vinci.rr.net.

The thing is that I've already edited /etc/resolv.conf. I've inserted nameserver 192.168.1.107
It's the same. Moreoever, after I reboot my computer a new line keeps showing up in the resolv.conf: "search net" or something like that, I'm not exactly sure now. I guess it might be connected.

Looks like you are using dhcp ip address and your router/dhcp server configured to append .net
Either change dhcp config or configure your test client static ip and change resolve.conf again make sure point to your dns server.

The actual problem was that I was pinging "vinci.rr" which wasn't associated with the host's IP. If I had pinged ns1.vinci.rr or www.vinci.rr it would have worked. But I did change to static anyway and there's no .net suffix anymore, so that might have something to do with it too.
