I installed ISPConfig 3 Perfect server solution for Centos 7. Out of the many installations available I installed Postfix, Pureftpd, Bind, Jailkit, Fail2Ban, and RKhunter. I did not install spamassasin, amavisd-new, clamav, and the rest because I am using Postfix as send only email. I also installed ISPConfig 3 then did the following DNS setting: A mail XXX.XXX.XXX.XXX 0 1800 A ns1 XXX.XXX.XXX.XXX 0 1800 A ns2 XXX.XXX.XXX.XXX 0 1800 A ns2ravemavencom XXX.XXX.XXX.XXX 0 3600 A ravemaven.com XXX.XXX.XXX.XXX 0 3600 A www XXX.XXX.XXX.XXX 0 3600 A wwwravemavencom XXX.XXX.XXX.XXX 0 3600 MX ravemavencom XXX.XXX.XXX.XXX 10 3600 NS ravemavencom ns1ravemavencom 0 3600 NS ravemavencom ns2dotravemavencom 0 3600 TXT ravemavencom v=spf1 mx a ~all 0 3600 1 And I also add the site ravemavencom in ISPConfig 3 which reads Yes server1.ravemavencom ravemavencom. The issue is that if I ping my VPS IP address and nameservers - ns1ravemavencom and ns2ravemavencom, I am getting ping back results, which indicates that they are resolving well. But pinging the site ravemavencom or wwwravemavencom returns "ping result cannot find host ravemavencom. Please check the name and try again later". On browser i get this "This site can’t be reached ravemavencom’s server DNS address could not be found." The log file reads the following errors which is suspected that The Named configuration is denying DNS request. The log report is =========== Dec 10 06:37:16 server1ravemavencom named: client 126.96.36.199#23643 (adobe.com): query (cache) 'adobecom/A/IN' denied Dec 10 06:37:16 server1ravemavencom named: client 188.8.131.52#60793 (ravemaven.com): query (cache) 'ravemavencom/NS/IN' denied Dec 10 06:37:16 server1ravemavencom named: client 184.108.40.206#32787 (wwwravemavencom): query (cache) 'wwwravemavencom/A/IN' denied =========== Please how can I solve this issue and to enable my domain name to start resolving well.
