BIND (is there anyting else?)

DNSSEC

dnssec-keygen -a 7 -b 2048 -n ZONE domena.org
dnssec-keygen -f KSK -a 8 -b 4096 -n ZONE domena.org

copy generated files in /etc/bind/keys.

if you put your keys in /etc/bind/keys do not forget about permissions and apparmor!

put this in zone domena.org

inline-signing yes;
auto-dnssec maintain;
key-directory "/etc/bind/keys/domena.org";
sig-validity-interval 3;  // default is 30D

use dnssec-dsfromkey to create DS DNS records from KSK files.

To enable add to bind.named.options:

dnssec-validation auto;
dnssec-enable yes;
dnssec-lookaside auto;

Add DS records at your domain registrar!

check your domain with http://dnsviz.net/

https://www.dns-oarc.net/files/odvr/configs/bind/trusted-keys.conf

logging {

      category dnssec { null;};};\\

Letting bind/named query a specific DNS server for only one specific domain

Add to the file /etc/bind/named.conf.local:

zone "mydomain.com" {
	type forward;
	forward only;
	forwarders { 192.168.0.2; 192.168.0.6; };
};

Of course you need to replace 'mydomain.com' as well as the 2 ip addresses in the 'forwarders'-line.

Unsorted

host -t txt -c CHAOS version.bind localhost

named - options {version “DNS daemon”;};

host -t txt -c CHAOS hostname.bind localhost

gethostbyname()

audit dns

kernel: audit(1209076817.081:16): type=1503 operation="inode_create" requested_mask="w::" denied_mask="w::" name="/etc/bind/xxxxx.com.hosts.jnl" pid=16561 profile="/usr/sbin/named" namespace="default"

So I had a look in: /etc/apparmor.d/usr.sbin.named

and changed this line:

/etc/bind/** r,

to this:

/etc/bind/** rw,

Fixing syntax highlighting in VIM
