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

Thanks for your help.Actually this will be implemented on next week.

I have another query.

1.Shall I need to install some bind patches first?

2.Whether the server need some internet connection or not? i.e.if we try to open firefox from the server will it be connected to the internet?

Again thanks for your help.

[Jupinder Bedi]

yes bind package should be there before installing you can check it using swlist command

and also

internet is connection must required for connecting the outer world and also you need to register one domain name first.

[Surajit Santra]

Thanks for your kind help.

There is no bind package installed in our server.Where can I get this package? Is it free available in the internet?
After installing the bind package shall I follow your steps? Or I have to do some configuration changes after installing the bind package? Is there any particular version of bind package that shall we install?

[Jupinder Bedi]

you can download the bind package from the internet or hp website and yes go thorugh the procedure as I told you step by step and if you will face any kind of difficulty please let us know , we are here to help you out. Installing DNS on hpux is very simple than any other unix OS


Best of luck

[Surajit Santra]

Hi I am doing the above mentioned steps.

I have added /etc/hosts file

128.1.1.1 syam.india.mum.com syam ( This is master server)
128.1.1.2 syam1.india.mum.com syam1 (This is for slave server)

and I have added in param file
-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

In param file I have given only the entry for the master server.i.e -d syam.india.mum.com

Now when I am running hosts_to_named -f param

It is giving the following error.

" 128.1.1.2 syam1.india.mum.com syam1
( First name not in syam.india.mum.com )

Please help me.
