== Dns views ==<br />
Dns views is enabled to perform separate query for external and internal client,example of exter and internal view below<br />
<br />
External: /etc/externalview.zone<br />
<br />
[[Image:]]<br />
<br />
<br />
Internal: /etc/internalview.zone<br />
<br />
[[Image:]]<br />
<br />
= TSIG key configuration =<br />
/var/named/chroot/etc/secure.key<br />
<br />
[[Image:]]<br />
<br />
<br />
Now the zone files will be transferred to those servers only who is having this secure key.</div>
