Hello guys, good day.. I have configured a DNS machine but i think im lost already.
Here is what i have done so far:

1. I have register a domain blucard.com, and I setup a DNS(ns1.pl.blucard.com) at home
2 I already added a record ns1.pl.blucard.com pointing to the ip address(123.111.1.1) of my dns server at home
3. I setup bind(not chrooted) in ns1.pl.blucard.com and here are my configs.

/etc/named.conf

PHP Code:


		
			
options {

        listen-on port 53 { any; };

        listen-on-v6 port 53 { any; };

        directory       "/var/named";

        dump-file       "/var/named/data/cache_dump.db";

        statistics-file "/var/named/data/named_stats.txt";

        memstatistics-file "/var/named/data/named_mem_stats.txt";

        allow-query     { any; };

        recursion yes;

};

logging {

        channel default_debug {

                file "data/named.run";

                severity dynamic;

        };

};

zone "." IN {

        type hint;

        file "named.ca";

};



zone "pl.blucard.com"  IN {

    type master;

    file "pl.blucard.com.zone";

    notify yes;

    #allow-transfer {192.168.245.0;};

};

/var/named/pl.blucard.com.zone

PHP Code:


		
			
$ORIGIN .

$TTL    3600 ; 1 hour

pl.blucard.com    IN      SOA     ns1.pl.blucard.com.    admin.blucard.com. (

                 2012121102 ; serial

                 10800      ; refresh (3 hours)

                 3600       ; retry (1 hour)

                 604800     ; expire (1 week)

                 86400      ; minimum (1 day)

                 )



        

        NS    pl.blucard.com.



pl.blucard.com    IN    A    123.111.1.1

test.pl         IN      A       123.111.1.1

NOTE: i havent configured yet a reverse-lookup zone.

However after doing all these stuffs, i cant ping ns1.pl.blucard.com and test.pl.blucard.com. Adding ns1.pl.blucard.com record
to the domain registry is about 2 days now.. so i think it is propagated already. Please advice me what to do... thanks
in advance...

i tried to troubleshoot the server but still no luck,

netstat -tulpn | grep 53

Hi,

Note that you need the glue record between the domain blucard.com and the subdomain pl.blucard.com. Take a look at the output of the following dig commands:

Code:

dig blucard.com +short

121.78.127.249



dig ns blucard.com +short

ns2.comn.com.

ns1.comn.com.



dig pl.blucard.com +short

121.78.127.249



dig ns pl.blucard.com +short

As you see there is no NS defined for the subdomain pl.blucard.com. You should go in the zone file of blucard.com and add an NS RR pointing to your server, e.g.

Code:

<snipped blucard.com zonefile>

pl.blucard.com.   NS ns1.pl.blucard.com.

Also keep in mind that in your OP you have pl.blucard.com as the NS RR of the pl.blucard.com zone and not ns1.pl.blucard.com. In the latter case you need an A RR for ns1.pl.blucard.com too.

If you want to use dig to do reverse queries you'll need the -x switch like this:

Code:

dig -x 123.111.1.1

But you said in your OP that you haven't configured the reverse zone yet.

hi bathory,,

pl.blucard.com is already added in the zone file of blucard.com.. and here is my new /etc/named/pl.blucard.com.zone file. i tried adding a record for ns1 and test.pl

PHP Code:


		
			
$ORIGIN .

$TTL    3600 ; 1 hour

pl.blucard.com    IN     *SOA    * ns1.pl.blucard.com.    admin.blucard.com. (

                 2012121102 ; serial

                 10800 * * *; refresh (3 hours)

                 3600 * * * ; retry (1 hour)

                 604800 * * ; expire (1 week)

                 86400 * * *; minimum (1 day)

                 )

        NS    sys1.blucard.com.

        NS    ns1.pl.blucard.com.

$ORIGIN pl.blucard.com.

pl.blucard.com    IN    A    123.111.1.1    

test            IN     A    123.111.1.1

ns1        * * * **IN    A    123.111.1.1

...i can ping / dig ns1.pl.blucard.com but after several hours i cannot.. :(.. please tell me what to do...

What is that you cannot...?
I can also resolve ns1.pl.blucard.com from here as well as test.pl.blucard.com, even though there are no NS for the pl.blucard.com subdomain:

Code:

dig ns1.pl.blucard.com +short

121.78.127.249

dig test.pl.blucard.com +short

121.78.127.249



dig ns pl.blucard.com +short

So please post the blucard.com zonefile.
Besides you don't need the line "$ORIGIN pl.blucard.com." in the pl.blucard.com zonefile. Also check the trailing dots after hostnames, as you miss some of them.

Regards
