<p>Good morning, I'm trying to make it more difficult for an
attacker to get my DNS server version. I have been following
several posts about doing this and mostrly all of them suggest to
modify the <b>/etc/bind/named.conf.options</b> file and add the
lines:</p>
<p>options {</p>
<p>version "Not available"; // Or any bogus
info or just none without quotes<br>
</p>
<p>}</p>
<p>Then restart the service (<b>service bind9 restart</b>) and the
version will not be shown, only the defined text, in this case
"Not available". However, after doing this and restarting the
service I'm still getting my server version. Am I placing this
lines in the wrong file? Thanks in advance!<br>
