DNS config server + firewall

I’m an utter newbie when it comes to DNS configuration. I just installed config server security + firewall. I love it! But, when I run a server security test I’m warned about the recursive DNS. I tried to fix this problem by editing named.conf and turning recursion off. This caused strange errors with Fantastico so I changed named.conf back to its original settings. So my question is should I really be concerned about recursive DNS?

Also after reviewing my dns configuration on dnsreport.com I have 3 errors and I was wondering if someone could please post a link with some documentation on how to fix these errors posted below.

1, Missing (stealth) nameservers dns3.waloop.org
2, Missing nameservers 2 ns1.greatlakehost.com
3, Stealth NS record leakage dns3.waloop.org

Thanks, Chad

 

thank you

Thank you for the help senthil

I double checked my account on godaddy and I’m only using 'ns1.greatlakehost.com; dns2.waloop.org; dns1.waloop.org name servers I cannot find anything for dns3.waloop.org at godaddy. dns3.waloop.org was an old name server I have since deleted. Any idea on where I could an instance of this old name server on WHM or in named.conf that might be causing this error?


EDIT:

Ok i found this in var/named/waloop.net.db

; cPanel 10
; Zone file for waloop.net
$TTL 14400
@ 86400 IN SOA ns1.greatlakehost.com. Ph3nology.gmail.com. ( 2007040100 ; serial, todays date+todays
86400 ; refresh, seconds
7200 ; retry, seconds
3600000 ; expire, seconds
86400 ) ; minimum, seconds

waloop.net. 86400 IN NS ns1.greatlakehost.com.
waloop.net. 86400 IN NS dns2.waloop.org.
waloop.net. 86400 IN NS dns1.waloop.org.

waloop.net. IN A 72.36.194.42

localhost.waloop.net. IN A 127.0.0.1

waloop.net. IN MX 0 waloop.net.


The text in red was:
SOA dns1.waloop.org.
waloop.net. 86400 IN NS dns1.waloop.org.
waloop.net. 86400 IN NS dns2.waloop.org.
waloop.net. 86400 IN NS dns3.waloop.org.
Which i have changed to the above.

I restarted my dns and i still get the same errors at dnsreport.com.
Do i have to wait 24 - 48hrs for change to take effect?

EDIT # 2:
Fixed! I was able to login to WHM at home and fix the problem by going DNS Functions >> Edit DNS Zone.
All errors i was concerned about are fixed
