nslookup, domain issue
 

I found that while I nslookup my dns server from one of client, It doesn't nslookup with hostname while it does with FQDN.

But it works all good when I try to nslookup other client.

I have entered "search domainname" in resolv.conf.

Can any one tell reason. Is it like that itself or somewhere I am missing something.

Attaching screenshot.

You have two domains example.com and centbox1.example.com. If ns1 is authoritative for both then they both need to have zone files.

Since you have a hostname with a dot, you need to increase ndots in /etc/resolv.conf (the default=1), so the resolver will use the search domain before doing an absolute name lookup even when queried for a hostname containing a dot:
For more details read the resolv.conf manpage

@bathory Thanks for reply. It worked. I have read man pages now.

@smallpod Thanks.Even I have thought to do the same. I will try it also.
