Do you have a DNS server in place ??

If you want configure ur hpux server as dns client
1)edit /etc/nsswitch.conf and update the host entry like below

hosts: files dns

2) edit /etc/resolv.conf
and create entry

nameserver

use the following link

I hope the following could be useful to you.

Configuring DNS
====================

I.Configure your Master DNS:-
============================

1 Delete all entries from /etc/hosts except local host entry and hosts in your domain.
Put FQDN for all hosts.See the example for a server called syam

#vi /etc/hosts
127.0.0.1 localhost
128.1.1.1 syam.india.mum.com syam
128.1.1.2 syam2.india.mum.com syam1
128.1.1.3 test.india.mum.com test

2 Create a directory for the DNS database file and cd to it

#mkdir /etc/named.data
#chmod 755 /etc/named.data
#cd /etc/named.data

3. Create a param file for your domain

#vi param

-d syam.india.mum.com # Use your domain name(s) here
-n 128.1.1 # Use your subnet address(es) here
-z 128.1.1.1 # Use your master server's IP here
-b /etc/named.conf

4. Run hosts_to_named

#hosts_to_named -f param

5. Download db.cache to the current dir.

6. Enable NAMED in the /etc/rc.config.d/namesvrs

#vi /etc/rc.config.d/namesvrs

NAMED=1
NAMED_AGRS=""

7. Start the named daemon

#/sbin/init.d/named start

II. Configuring Slave DNS:-
===============================

1. Create a directory for the DNS database file and cd to it

#mkdir /etc/named.data
#chmod 755 /etc/named.data
#cd /etc/named.data

2. FTP copies the db.* files from the master DNS.

#ftp 128.1.1.1 # Use your master DNS Server's IP Here
>mget /etc/named.data/db.*
>bye

3. FTP a copy of conf.sec.save from the master DNS server and move it into place on the slave server as /etc/named.conf

#ftp 128.1.1.1 # Use your Master DNS IP here.
>get /etc/named.data/conf.sec.save
>bye

#mv /etc/named.data/conf.sec.save /etc/named.conf

4. Enable NAMED in the /etc/rc.config.d/namesvrs

#vi /etc/rc.config.d/namesvrs
NAMED=1
NAMED_ARGS=""

5. Start the named daemon

#/sbin/init.d/named start

III. Configure the DNS clients;-
==================================

1. Modify the resolver file. Include the DNS IPs in the search list.Include both Master and mSlave server in the namesservers list.

#vi /etc/resolve.conf

search xyz.india.mum.com # replace this with your domain name
nameservers 128.1.1.1 # Replace 128.1.1.1 with your Master DNS IP
nameservers 128.1.1.2 # Replace 128.1.1.2 with your Slave DNS IP

2. If your /etc/nsswitch.conf exists, delete it. You can experiment with the default behaviour for now.

#mv /etc/nsswitch.conf /etc/nsswitch.conf.orig
3. Slave DNS and Clients need to modify /etc/hosts at this time.

#vi /etc/hosts

127.0.0.1 localhost
128.1.1.3 test.india.mum.com test

Good luck

If it's for mail server, you need a recursive server like BIND :

Hi,
Yesterday i have configured the 2 hpux servers as DNS client.

I edited and updated the host entry in /etc/nsswitch.conf file as
hosts: files dns

and also edited /et/c/resolv.conf and create the entries for Primary and secondary DNS servers as
nameserver

When i pinged the mgw it is pinging for one server and for the other server i have received the message as
$ /usr/sbin/ping mgw
/usr/sbin/ping: unknown host mgw

Kindly recommend me how to troubleshoot this.

Thanks you all for giving your advises.

Shalom,

You can do this without DNS.

/etc/hosts networking is sufficient to resolve the names.

The nice thing is BIND works the same way, with the same configuration files as BIND on Linux.

Same source code.

Can anybody help me to resolve this.

For one of the server is working nicely whereas other is not pinging as i followed the same steps.

Re: DNS setup for hp-ux machine

S.S. — Fri, 05 Feb 2010 06:08:09 GMT

Please the output of nslookup:

$ nslookup mgw
Using /etc/hosts on: oraap2

looking up FILES
*** No address information is available for "mgw"
$

whereas for the other server, i am able to see the address information.

Jupinder Bedi — Fri, 05 Feb 2010 07:47:03 GMT

have you mentioned mgw in the DNS . please check all the lookup files in the DNS and also you can also mention the name of the server in the local /etc/hosts file .

if its still not working than please respond .

and also assign the points to all who helped you in this thread
