Re: how to use nslookup to search 2nd DNS server
Frist check with resolv.conf then u got the dns entery in the that file.
Use the following step to resolve.
root # nslookup 135.37.9.18
Using /etc/hosts on: ts330
looking up FILES
Name: gab200dns.qip.hp.com
Address: 135.37.9.18
ah330 root # nslookup gab200dns.qip.hp.com
Using /etc/hosts on: ts330
looking up FILES
Name: gab200dns.qip.hp.com
Address: 135.37.9.18
ah330 root # nslookup 135.38.244.3
Using /etc/hosts on: ts330
looking up FILES
Trying DNS
Name: mo3980dns.qip.hp.com
Address: 135.38.244.3
Then u got the primay DNS & seconday DNS.
Thanks

Re: how to use nslookup to search 2nd DNS server
> Every one of those nslookups returns the fact that it is using /etc/hosts and not a dns server at all.
Not true. The third one looks to DNS, but I'm still confused by what is being attempted.

Re: how to use nslookup to search 2nd DNS server
# nslookup
> server

I'm curious why the hostname doesn't exist on both servers? DNS was designed as a distributed, resilient name service, and assumes that everything is the same whichever server you use (excluding zone propagation delays).

Re: how to use nslookup to search 2nd DNS server
See the example
User: nslookup toolah.fourex.oz wurrup.fourex.oz
System: Server: wurrup
Address: 101.3.104.12
Name: toolah.fourex.oz
Address: 101.3.100.2
If you want to know more about nslookup see the below link.
