Howto: Setup a DNS server with bind

[rededit]

I fixed my problem. I have my domain running I think. The problem is I cannot browse to the my internal site via the new domain name.

Here are the results of the tests:

ja@x:/etc/apache2$ ping x.local

It seems as though I have everything configured correctly, yet I still cannot browse to the site I have hosted off of the nameserver 192.168.2.20. The router ip is 192.168.2.1.

Here are my files:

//

// organization

zone "x.local" {
        type master;
        file "/etc/bind/zones/x.local.db";
        };


zone "2.168.192.in-addr.arpa" {
     type master;

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

           forwarders {
                192.168.2.1;
           };

search x.local

Any help would be greatly appreciated. I can't seem to figure out what I am doing wrong.

Edit: I can browse to the site by putting in the ip address of the nameserver/webhost into my browser.

Hi,

Sorry to be resurrecting a dead thread here, but I cannot get it to work. I cannot resolve my own machine's hostname!

Here are my files:

zone "communicate.local" {
type master;
file "/etc/bind/zones/communicate.local.db";
};

zone "0.168.192.in-addr.arpa" {
type master;
file "/etc/bind/zones/rev.0.168.192.in-addr.arpa";
};

options {
directory "/var/cache/bind";
forwarders {
192.168.0.1;
};
auth-nxdomain no;
listen-on-v6 { any; };
};

communicate.local. IN SOA zeus.communicate.local. admin.communicate.local. (
2006081401
28800
3600
604800
38400
)
communicate.local. IN NS zeus.communicate.local.
* IN A 192.168.0.2
zeus IN A 192.168.0.2

@ IN SOA zeus.communicate.local. admin.communicate.local. (
2006081401;
28800;
604800;
604800;
86400
)

IN NS zeus.communicate.local.
2 IN PTR communicate.local
2 IN PTR zeus.communicate.local

nameserver 192.168.0.2
domain communicate.local
search communicate.local

bind9 starts fine, but when I try nslookup zeus 192.168.0.2, I get:

Server: 192.168.0.2
Address: 192.168.0.2#53

** server can't find zeus: NXDOMAIN

If anybody knows what could be causing my problem, I would appreciate it if you could let me know. By the way, this happens whether I run the nslookup from the zeus itself (the DNS server) or another machine on the network.

Thanks in advance for your help,
Grakul

Nevermind. I fixed it. I ran the following command:

named-checkzone example.com /etc/bind/db.example.com

It basically gave errors on each of the comment lines. I removed all the comments, after which the above line reported "OK."

I restarted bind and was able to resolve zeus and ping communicate.local.

Now to find out how to get my DHCP server to automatically update DNS for the clients....

Cheers

nice tutorial ! a want to try this !
thank's

[Delfines]

so good~

[rituranjan]

how to an other domain created with this domain

[TeamXlink]

How would I go about setting up a CNAME record.

Directing users of the DNS Server from:

www.example.com to www.other.com

I cannot use an A record because the ip address that www.other.com is dynamic and not static.


*Note - www.example.com and www.other.com are just examples.

Thank you.

Very good tutorials, still having issues, I'm using a live example here and just can't get it to work, here's my configuration so far:

I'm going to use mydomain.com as my domain name here

named.conf.local

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

zone "mydomain.com" {
	type master;
	file "/etc/bind/db.mydomain.com";
};

# This is the zone definition for reverse DNS. replace 0.168.192 with your network address in reverse notation - e.g my network address is 192.168.0
zone "201.168.192.in-addr.arpa" {
    	type master;
     	file "/etc/bind/rev.201.168.192.in-addr.arpa";
};

db.mydomain.com

;
; BIND data file for mydomain.com
;
$TTL	604800
mydomain.com.	IN	SOA	ns1.mydomain.com. admin.mydomain.com. (
	84739	; Serial
	604800	; Refresh
	86400	; Retry
	2419200	; Expire
	604800 ); Negative Cache TTL
;
mydomain.com.			IN	NS	ns1.mydomain.com.
mydomain.com.	86400	IN	NS	ns2.mydomain.com.
localhost		14400	IN	A	127.0.0.1
ns1				14400	IN	A	<external server IP>
ns2				14400	IN	A	<external server IP>
@	IN	A	127.0.0.1
@	IN	AAAA	::1

Any help would be appreciated.

That does not works for me. The file 'example.com.db' contains:

example.com.      IN      SOA     ns1.example.com. admin.example.com. (
                                                        2006081401
                                                        28800
                                                        3600
                                                        604800
                                                        38400
 )


example.com. IN NS ns1.example.com.
example.com. IN MX 10 mail.example.com.


www     IN      A       ***.***.***.***
mail    IN      A       ***.***.***.***
ns1     IN      A       ***.***.***.***

and here is result of named-checkzone:

# named-checkzone example.com example.com.db
example.com.db:1: no TTL specified; using SOA MINTTL instead
zone example.com/IN: loaded serial 2006081401
OK

But dig resolve successfully! What is wrong?
