Setting up DNS

Paul J. Ledbetter, II — Wed, 24 Mar 2004 18:39:55 GMT

Greetings,
I have a Windows Server 2003 set up as an internal DNS server. What do I need to do to set up my HP-UX 11i server to refer to the Windows server for all DNS lookups?

I tried setting up DNS(Bind). I set it up as a "slave" to the Windows server, pointing to it as the DNS resolver. When I do an nslookup , I get the following message:

*** Can't find server name for address : Non-existent domain
*** Default servers are not available
Using /etc/hosts on:

looking up FILES
Name:
Address:
Aliases:

What do I need to do?

Hi,

You need to configure /etc/resolv.conf and /etc/nsswitch.conf file in your HP-UX 11i server so that the DNS lookups from the 11i server will get forwarded to the windows server

# vi /etc/resolv.conf
domain
server
#

# vi /etc/nsswitch.conf
hosts: dns files
#

You do need network connectivity to the W2K server.

To merely obtain dns information, you do not need BIND installed at all.

The changes to nsswitch.conf and having the server in /etc/resolv.conf are enough.

This is what we use:

in /etc/resolv.conf

domain mydomain.com
nameserver xx.xx.xxx.x
nameserver xx.xx.xxx.x

in /etc/nsswitch.conf
hosts: files [NOTFOUND=continue UNAVAIL=return TRYAGAIN=return] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return]

Bind is not required.

Sundar,
The following is the contents of my resolv.conf:

domain
nameserver
search

I just put this in my nsswitch.conf:
hosts: dns files

Still the same thing

Miracle: I tried your solution: no-go.
Michael: I have network connectivity to W2K server.

Try a ping of DNS server.

If the ping succeeds

# telnet 53

The command should not return immediately.

From your desktop try this

# nslookup - <2003 DNS serverIP>

I can ping my Windows DNS server. I can even ping internet addresses by host name like www.google.com.

The telnet works as expected.

But still the same thing on nslookup, both on my XP pc and in my UNIX environment.

Run SAM and check this

Juan,
I do not understand what you are saying.

1) you can only have either the domain or the search keyword in the /etc/resolv.conf. Search can accept up to 6 domains.

2) Are there any firewall between the windows and unix server? Make sure port 53 for TCP and UDP is opened for name query and zone transfer.

3) do this manually:

nslookup

Do you get any output?

Sanjiv,
I had JUST set up a reverse lookup on my Windows 2003 server when I read the links you sent me. The problem is fixed. Thanks a lot.
