Issue with DNS client configuration...
I am trying to configure a DNS client and I'm encountering some issue....
DNS server and client are in the same network, client server can ping DNS server.
In /etc/nsswitch.conf file there is :
hosts: nis files dns
My /etc/resolv.conf file is :
domain mycompany.com
nameserver 10.145.34.29
and when I try to use nslookup I have this error message :
#nslookup sade120 10.145.34.29
Specified server is not available.
The configured name services and switch policy will be used.
*** Can't find server name for address 10.145.34.29: Non-existent domain
*** Default servers are not available
Default NIS Server: sade130
Address: 10.145.34.28
Trying NIS
Name: sade120
Address: 10.145.34.25

Someone can help me ?
Thanks,

Re: Issue with DNS client configuration...
I have changed the position in /etc/nsswitch.conf file (hosts: dns files nis) and I have the same issue.
"Specified server is not available."
#nslookup sade120 10.145.34.29
Specified server is not available.
The configured name services and switch policy will be used.
*** Can't find server name for address 10.145.34.29: Non-existent domain
*** Default servers are not available
Using /etc/hosts on: sade110
looking up FILES
Trying NIS
Name: sade120
Address: 10.145.34.25

Re: Issue with DNS client configuration...
If you can ping your DNS, then we know there is connectivity.
We are going to assume DNS is working fine.
Whenever we tell nsswitch to look at DNS to resolve name and IP address, it says that Specified Server is not available, then I would thing that either the DNS is not define and misconfigure in the /etc/resolv.conf
Please send us the content of that file please.
Regards,
jaime.

Re: Issue with DNS client configuration...
it seems that no named is running on your host 10.145.34.29 .
Try your nslookup command on that server directly - does it succeed?
Does your named run on a non-standard port (std is 53)?

Re: Issue with DNS client configuration...
It's ok now....
I have added an entry where I defined the DNS server itself and all is ok.
Thanks to all !!!
