DNS error

mvr — Mon, 30 Dec 2002 16:22:26 GMT

I have configured dns on RedHat 7.2 (using BIND 8.1)
When I use nslookup from the workstation (win 2000 or XP), I do get the answer but the server line said that server is uknown (see the attachment).
When I try to do the nslookup from the server (DNS server),
I do not get any answer, just an error
**** cant't find the server name ....
**** default server is not avelible .... (see attachment).

Any help will be welcomed ...

Is 10.10.10.4 your RedHat DNS server?

Try this on your M$ box:

nslookup servername 10.10.10.4

live free or die

Miro,

Verify that you have an entry for your DNS server in both the forward file and the reverse file. Normally, the error indicates that you missed a pointer entry for your DNS server in the reverse file. Remember to restart your DNS server after updating any files.

Make sure your windows DNS configuration has the right IP address, hostname and check if its fully qualified or not.

can you ping the linux box as

linuxbox.my.net

and linuxbox

??

I usually use IP addresses, but I don't currently manage any networks with more than 11 boxex.

Do a "ipconfig /all" from your w2k box.

What is listed as the DNS?

The reason the DNS hostname is not setup is that the reverse lookup zone is not setup.

Try do a nslookup or dig from your linux box.

nslookup -type=ns 10.10.10.in-addr.arpa

or

dig ns 10.10.10.in-addr.arpa

Do you see any NS record? If not reverse zone is not configured.

Hi,

nslookup when started will do a inverse lookup with the DNS's server's ip address to find out the DNS name of the DNS server. When there is not inverse record for the DNS server's IP address , it returns that error. you can see what is happening by running nslookup in debug mode.

There is no problem to DNS operation due to this error and DNS queries are answered normally.

c:\>nslookup -d1

check /etc/resolv.conf and /etc/nsswitch.conf on UNIX and DNS settings on WIndows
