DNS (Non authoritive Issue)

jwals · 01-12-2008, 01:39 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?

Did you ever find out a solution?
I have dns question and stumbled across your thread.

Hi,

Try using or adding additional DNS to your '/etc/resolv.conf'.
You can use third level DNS;

Code:

sample '/etc/resolv.conf';

search 192.168.1.1     

nameserver 207.179.200.2     #ISP DSN
nameserver 207.179.200.25    #ISP DNS
nameserver 207.179.200.10    #ISP DNS
nameserver 4.2.2.1           #Verizon third level DNS
nameserver 4.2.2.2
nameserver 4.2.2.3
nameserver 4.2.2.4

EDIT: If the placement of the third level DNS solve the issue then your original DNS is not setup properly.

Hello,

If you do not edit the information we can better assist.

Please do not change the domain name or IP addresses you are having a problem with.

It's confusing trying to read sanitized information.

Very true when DNS or mail servers are involved.
It's hard to spot a DNS configuration error if you can't query the actual data.
