DNS and authoritative answer |
|
|
hello,
my problem is a general problem
i've find for win98se "nslookup.exe" from old BINDNT port
it works great exept for my domain name, i cannot query authoritative
answer for willemijns.com (hosted by zoneedit) but i can for
google.com grin !
*************** nslookup -q=MX willemijns.com 207.234.248.200
Authoritative answers can be found from:
(root) nameserver = A.ROOT-SERVERS.NET
(root) nameserver = B.ROOT-SERVERS.NET
(root) nameserver = C.ROOT-SERVERS.NET
(root) nameserver = D.ROOT-SERVERS.NET
(root) nameserver = E.ROOT-SERVERS.NET
(root) nameserver = F.ROOT-SERVERS.NET
(root) nameserver = G.ROOT-SERVERS.NET
(root) nameserver = H.ROOT-SERVERS.NET
(root) nameserver = I.ROOT-SERVERS.NET
(root) nameserver = J.ROOT-SERVERS.NET
(root) nameserver = K.ROOT-SERVERS.NET
(root) nameserver = L.ROOT-SERVERS.NET
(root) nameserver = M.ROOT-SERVERS.NET
stderr indicate me
*** Can't find server name for address 207.234.248.200: No information
*** Default servers are not available
- With "nslookup.exe" WinXP, i can see good result after this 2 lines
information
- In BINDNT port, it stops after displaying this 2 lines information
webtools give me good result
http://www.analogx.com/cgi-bin/cgidig.exe?DNS=ns1.zoneedit.com&Query=willemijns.com&Type=15&Submit=Submit
http://centralops.net/co/NsLookup.vbs.asp?query=willemijns.com&server=ns1.zoneedit.com&type=255&class=1&port=53&timeout=5000&go=Submit
.........so my question is how to bypass this famous
"Can't find server name for address 207.234.248.200: No information" ? |

Don't use NSLookup - you get the problems that you have just found!
Instead use a Windows 32 port of Dig (there is one available in later
bind ports). Other than the error is this causing you any other
problems?
BTW are you the same person who compiled the free newsserver tests
some time ago?

You can ignore the "can't find server name for address 207.234.248.200" This
is nslookup trying to perform a reverse lookup for the IP address of the DNS
server.
The reason why the server you are asking cannot find the PTR is because the
server you are asking (207.234.248.200) to find the PTR is a non-recusive
DNS and can only answer with records it owns or with a referral to the Root
servers if it doesn't own the record. It could answer with the MX record,
because it owns it, but not the PTR record because the PTR is owned by
ns1.primarydns.com. and ns2.primarydns.com hence you get a referral to the
root for the PTR. This is just one of nslookup's bugs showing itself.
Nslookup is not the best tool for doing DNS lookups, the only reason I would
tell someone to use nslookup is because it is included with versions of
Windows NT and does not have to be downloaded or installed. A much better
tool IMO, is Netdig by William Stacey available from www.mvptools.com, it
only requires .NET Framework installed, if ran from a local drive.

As has been confirmed by Kevin, it is just a silly error from
NSLookup.

yes, i have now the latest win98se compatible NTBINDpack (9.2.2) and
it works well but it requieres a lot of big DLL (libeay32.dll
libdns.dll and more and more) to works... |

thanks of this answer but i'm very surprising this trouble was
resolved only in BIND 9.1 (since 2003) |
