NSlookup fails, DDNS & DHCP

HellSpawn · 04-14-2005, 10:43 AM

I have a Fedora Core 3 DDNS DHCP Server, it seems to be working fine, because every body can go around the network useing the dns names, but when I try to do a nslookup from any Windows or Mac OS X machine I get:

c:\> $ nslookup linux
*** Can't find server name for address 192.168.0.1: Server failed
*** Can't find server name for address 192.168.0.2: Non-existent domain
*** rs26s16.datacenter.cha.cantv.net can't find linux: Non-existent domain
Server: rs26s16.datacenter.cha.cantv.net
Address: 200.44.32.12

192.168.0.1 is my DNS server.
The last DNS server is the one from my ISP.

But if a try nslookup from a Linux machine I get the proper answer I'm looking for.

I also get messages like these ones:

What may I be doing wrong??

*** Can't find server name for address 192.168.0.1:

It tried to do a query of a reverse DNS lookup of 192.168.0.1 and failed. Look into setting up reverse DNS for BIND. I'm sure a google search will get you started on how to set that up.

Yeap.. that was right benjithegreat98, I solved it stoping BIND, deleting the journal files and restartint BIND (named)...

Thanks!!

Look for those files on your /etc/named or /var/lib/named .... stop BIND, delete the files and restart BIND.

I do not see any journal files for named in the path above.
Can you please get me the name of the file, it would be, for me to check the whole system.

So you want me to go there and do the job for you too?? You can Google it....

Look for files with .jnl extensions, you can RTFM

chockalingam, please don't drag up old threads. this hadn't been touched for nearly 2 years! If you have a problem you then you should start a thread for yourself. try that next time... (not this time...)

HellSpawn, please play a little nicer next time, ehh?
