 ====== BIND (is there anyting else?) ======
-**Speedup tips**
+==== 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''**:
+<code>
+zone "mydomain.com" {
+	type forward;
+	forward only;
+	forwarders { 192.168.0.2; 192.168.0.6; };
+};
+</code>
+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 ====
+<code>
+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"
+</code>
+So I had a look in:
+''/etc/apparmor.d/usr.sbin.named''
+and changed this line:
+<code>
+/etc/bind/** r,
+</code>
+to this:
+<code>
+/etc/bind/** rw,
+</code>
+==== Fixing syntax highlighting in VIM ====
+**~/.vimrc**
+<code>
+" BIND zone
+au BufNewFile,BufRead */named/db.*,*/bind/master/*,*/bind/slave/*,*/bind/arpa/* call s:StarSetf('bindzone')
+" BIND configuration
+au BufNewFile,BufRead named.conf,rndc.conf,arpa.conf,named*,master.conf,slave.conf      setf named

-  You should use BIND 9, disable lookups over IPv6 (OPTIONS="-u bind -4"
-  in /etc/defaults/bind9), and you need to wait a bit until the local
-  cache has been filled.
