How to configure BIND 9.5

[loik]

Can someone please help me to configure BIND 9.5.

I am running Fedora Core 8 in GUI and I have Webmin installed.

I did a couple of things but it does not seem to work. I created a master zone for my domain, in the master zone I configured the name server to my hostname. I have entered public DNS IP's in "Forwarding and Transfers" for my server to forward queries to.

This does not work, when I try to access google I cannot but when I go out on the IP I have no problems.

Can someone please tell me what am I leaving out or doing wrong.

thanks,
loik

Are you using chroot bind?
Can you post your config files for bind?
I don't use webmin so i cannot tell you what the problem is there.

Hi. Thanks for the reply.

How do I know if I am using chroot bind?

here are my config files:

"named.conf":

options {
listen-on port 53 {127.0.0.1; };
listen-on v6 port 53 { ::1; };
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 {localhost; };
recursion yes;
forwarders {
168.210.2.2;
196.14.239.2;
};
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};

zone "." IN {
type hint;
file "named.ca";
};

include "/etc/named.rfc1912.zones";

zone "mydomain.co.za" {
type master;
file "/var/named/mydomain.co.za.hosts";
};
};

"Master zone file":

$ttl 38400
mydomain.co.za IN SOA ns1.mydomain.co.za legrangeb.gmail.co.za (
1221478551
10800
3600
604800
38400 )
mydomain.co.za IN NS ns1.mydomain.co.za.

Hi. Thanks for the reply.

How do I know if I am using chroot bind?

Look at the init script that starts bind.
How is bind called?

Did you install bind or bind-chroot?
I think fedora defaults to the chroot bind.

here are my config files:

"named.conf":

include "/etc/named.rfc1912.zones";

What is this include statement?
What is in this file?

"Master zone file":

$ttl 38400
mydomain.co.za IN SOA ns1.mydomain.co.za legrangeb.gmail.co.za (
1221478551
10800
3600
604800
38400 )
mydomain.co.za IN NS ns1.mydomain.co.za.

Where is the A record? You are saying that ns1 is the name server for mydomain.co.za but you are no telling the ip address of ns1 which is needed.

What does your /etc/resolv.conf look like?

I have managed to see that bind is installed in chroot.

What I also did is deleted the “name.conf” file and my “mydomain.co.za.hosts” file and restarted bind. Bind then created a new “named.conf” file, this had only a master zone setup and not all the other default zones.

I created a master zone for “mydomain.co.za” and created a A record for my name server. I have entered the ADSL route’s IP address in for forwarding and this is all working fine.

This is my current named.conf file:

options {
directory "/etc/";
pid-file "/var/run/named/named.pid";
listen on port 53 {100.0.0.1;};
forwarders {192.168.2.1;};
};

zone "." {
type hint;
file "/etc/db.cache";
};

zone "mydomain.co.za" {
type master;
file "/var/named/mydomain.co.za.hosts";
};

Master zone file:

$ttl 38400
mydomain.co.za IN SOA ns1.mydomain.co.za legrangeb.gmail.co.za (
1221478551
10800
3600
604800
38400 )
mydomain.co.za IN NS ns1.mydomain.co.za.
ns1.mydomain.co.za IN A 100.0.0.1

All well but now how do I configure bind to use the root zone and forward queries directly to the root DNS servers?

[Lazydog]

This is done with your hints file.

 zone "." {
    type hint;
    file "/etc/db.cache";
    };

You need to change this to something else unless you plan on using this file for your root servers.
Maybe root.hints.db

Here is what mine looks like:

zone "." IN {
                type hint;
                file "slaves/root.db";
        };

I run a chroot environment with SELinux running.

Then take a look at this site on how to update your hints file.

[loik]

Do I have create a new file called "root.hints.db" and copy the information form "/etc/db.cache" in to this file and change my "named.conf" to point to this file?

I don't know if I am understanding you right.

[Lazydog]

I would create a file called root.hints.db and then populate it like is outlined in the link above. I cannot tell you to copy over the contents of the cache file as I do not know what is in this file.

Hello every one.
I have a little “newbie” question here.
I’m running Ubuntu server and bind9.5 . And accidently removed all the files from /etc/bind/
Well now the bind won’t start.

#/etc/init.d/bind9 status
* bind9 is not running.

#/etc/init.d/bind9 start
* Starting domain name service... bind9 [fail]
Here are the log entries:

#tail /var/log/daemon.log
Mar 13 17:03:08 nicks-server named[5935]: starting BIND 9.5.0-P2 -u bind
Mar 13 17:03:08 nicks-server named[5935]: found 1 CPU, using 1 worker thread
Mar 13 17:03:08 nicks-server named[5935]: loading configuration from '/etc/bind/named.conf'
Mar 13 17:03:08 nicks-server named[5935]: none:0: open: /etc/bind/named.conf: file not found
Mar 13 17:03:08 nicks-server named[5935]: loading configuration: file not found
Mar 13 17:03:08 nicks-server named[5935]: exiting (due to fatal error)

I tried to reinstall bind by but it gave me the same error.

#sudo apt-get remove bind9
#sud0 apt-get install bind9

It there is a way I can copy the files or how can I fix the problem.
Thank you for your time.

I hope you made backups of your config files. You don't have a named.conf file so bind doesn't know what to do. You need to recover from your backup or create a new namd.conf file.
