setup DNS Master zone

'chris' — Thu, 09 Mar 2006 12:38:06 GMT

hi

I've setup Master DNS-Server BIND 9 on linux Debian Sarge
and it seems to work,
but I'm not sure if I've setup the Master Zone of this name server correctly.

short information:
ext.domain.net is the name of this name server
and domain.net is domain of this name server

I've done following using the webmin:

1.) first I've created a new reverse master zone:

zone "205.X.X.in-addr.arpa" {
type master;
notify yes;
file "/etc/bind/205.X.X.rev";
};

2.) next step, I've created a master zone for my dns server ext.domain.net:

zone "domain.net" {
type master;
file "/etc/bind/domain.net.hosts";
notify yes;
allow-query { any; };
};
3.) I've opened the zone master zone: domain.net, clicked on Address and I've put the following:
ext.domain.net. Default 205.X.X.10
domain.net. Default 205.X.X.10
www.domain.net. Default 205.X.X.10

now I have:

# vi domain.net.hosts

$ttl 38400
domain.net. IN SOA ext.domain.net. postmaster.domain.net. (
1141342035
10800
3600
604800
38400 )
domain.net. IN NS ext.domain.net.
ext.domain.net. IN A 205.X.X.10
domain.net. IN A 205.X.X.10

I'll be very happy, if someone could check this entries and let me know.

kind regards
chris

The first part of step 3 i did not understood, where you configured?

ext.domain.net. Default 205.X.X.10
domain.net. Default 205.X.X.10
www.domain.net. Default 205.X.X.10

Also the last entry for your zone is incorrect:

domain.net. IN A 205.X.X.10

That is wrong, you won't assign an ip address to a domain. That could be for an MX RR, like this:

domain.net. IN MX 10 mail.domain.net.

You didn't post your reverse zone file.

in step 3 I wrote what I did using the webmin

and reverse zone is:

# vi 205.X.X.rev

$ttl 38400
X.X.205.in-addr.arpa. IN SOA ext.domain.net. postmaster.domain.net. (
1141342019
10800
3600
604800
38400 )
X.X.205.in-addr.arpa. IN NS ext.domain.net.
10.X.X.205.in-addr.arpa. IN PTR ext.domain.net.

Your reverse zone file seems to be good, considering that you still don't almost any entry. Good luck with your server configuration, use the dig command to test your server.

thanks a lot !

should I remove:

domain.net. IN A 205.X.X.10

from the master zone ?

Yes, you should remove that line.

but, if I remove this line, nslookup is not working anymore:

# nslookup domain.net
Server: 127.0.0.1
Address: 127.0.0.1#53

*** Can't find domain.net: No answer

before was working well.

Your nslookup query is wrong. Instead of nsloookup you should use dig, and you should ask for a specific DNS Resource Record, not just ask for the domain, like this:

To query the Name Server for domain.net
dig domain.net NS

To query the address for ext.domain.net
dig ext.domain.net

Check the answer section.

Ok, now I understand, you want to connect to your web server without specifying the host name. I haven't think about that. If this is what you want, do not remove that line.

Sorry for the wrong support.
