DNS Error

[Darren Murray_1]

hi,

I am doing a nslookup error from my pc and get the following error. It resolves the host name I look up but the DNS server name fails.

Please help
Darren

C:\>nslookup gfbvicn1
*** Can't find server name for address 10.1.9.3: Server faile
*** Default servers are not available
Server: UnKnown
Address: 10.1.9.3

Name: gfbvicn1.mb.goodmanfielder.com.au
Address: 151.3.64.31

Hi,

you need not worry about this.

When nslookup starts up . it will do a inverse lookup for the name server's IP address listed in /etc/resolv.conf to get the DNS name. If it does not get the hostname it gives above error.

This inverse query is not necessary and it's failure will not affect any other DNS resolutions of the server to the client.

you can learn more by running nslookup in debug mode.

#nslookup -d1

will show the inverse query made.

This means that your nameserver doesn't have a reverse DNS entry for its
own address. Use dig instead of nslookup.
