If you already have DNS server, then it is pretty simple to configure your other boxes as DNS client.

On the server which you want as DNS client
1. Edit /etc/nsswitch.conf and modify the hosts entry to look like
hosts: dns [TRYAGAIN=continue NOTFOUND=continue] files
and modify aliases entry to look like
aliases: dns files

2. In the file /etc/resolv.conf add the entries for your DNS server as below e.g.
nameserver 10.220.1.5

Thats all.

Hi

It may be easy to use SAM like beloow step

sam > select Network and Communication > DNS (Bind) > DNS Resolver

In the mune, you can define the name server IP and hostname.
Once you finish inpuuting, the DNS information is reflected your system automatically.

hi,

In fact I need to ping hostname of the system. I can ping using ip_address of the system but can not ping using the hostname. In the /etc/hosts file I have enter the ip_address and hostname in the second line and loopback address is in the first line. There is no alias entry in the /etc/hosts file.

So to resolve the hostname what else I need to do. Say, if I don't have a DNS server in my LAN.

Hi,


Contrary to your earlier question - which you said you have a DNS server and you want to configure a DNS client, it seems you wish to use /etc/hosts file instead.

If you dont have DNS server, then you can use the /etc/hosts file to map server names to ip addresses. e.g. /etc/hosts file
127.0.0.1 localhost loopback
10.140.2.79 server1
10.141.2.74 server2
10.140.84.71 server3


Also you can set the /etc/nsswitch file hosts entry as -
hosts files

And you should be able to ping the servers mentioned in the /etc/hosts file using server name.

Can you paste your /etc/hosts and /etc/nsswitch.conf files here if you still have any problems.

As stated you have DNS, I provided you with just procedure of configuring DNS client, but your problem wasn't that.

You really should consider two files /etc/hosts and /etc/nsswitch.conf
as Ninaid said..

You need to change lookup sequence in nsswitch.conf looking from

files [NOTFOUND=continue] dns

also put alias for your hostname in /etc/hosts file like

alias name
