DNS (Non authoritive Issue) - Websites load very slowly

Posted by jwals, 01-12-2008, 11:51 AM
We have an issue with websites load very slowly in a new server (centos) and we recieve an email from the server stating the following: IMPORTANT: Do not ignore this email. The hostname (ns.domain.com) resolves to . It should resolve to xx.xxx.xxx.90. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain. Some are all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check this file if you believe everything else is correct. You may be able to automaticly correct this problem by using the ' Add an A entry for your hostname ' under ' Dns Functions ' in your Web Host Manager and when we restart "DNS Server (BIND)" or "named" we get as part of the output the following: view localhost_resolver: received notify for zone 'domain.com': not authoritative Please find below the contents of /etc/hosts , /etc/resolv.conf and /etc/sysconfig/network: /etc/hosts: ::1 localhost6.localdomain6 localhost6 # Do not remove the following line, or various programs # that require network functionality will fail. XX.xxx.xxx.90 ns.domain.com ns 127.0.0.1 localhost /etc/resolv.conf : #domain domain.com #search domain.com #nameserver 127.0.0.1 nameserver xx.xxx.xxx.92 nameserver xx.xxx.xxx.93 /etc/sysconfig/network: NETWORKING=yes NETWORKING_IPV6=yes GATEWAY=xx.xxx.xxx.xx HOSTNAME=ns.domain.com DOMAINNAME=domain.com So what could be wrong with the above settings?

Firstly check your resolv.conf file, hope the ip's in there for nameservers are not the ip's for your nameservers you setup on the server. Second what how are your nameservers setup, ns.domain.com and ns1.domain.com or different then this, be sure that the hostname of the server is not also one of the nameservers name. As for the email you got from Cpanel, you just have to add an A record for the hostname to the domain.com dns zone file.

1- The ip's are the ones that I setup for the server. 2- The hostname is: ns.domain.com Namesaervers: ns01.domain.com ns02.domain.com 3- There is already an A record available there.

Edit your resolv.conf file and add only this: search domain.com nameserver 4.2.2.1 nameserver 4.2.2.2 Check after this how it is the connection. You should use some authoritative nameservers in resolv.conf, even the ones your host has(the datacenter where you host the server, maybe ask them for their nameservers) or some big ISP's nameservers.

I have done so but the issue is still the same.

Can you post the domain name or send it using PM, it will be much more easy to help you if we know the domain name.
