UNIX for Dummies Questions & Answers

I am saying your box is living a happy life as a standalone box... he knows nothing about your network or others...
Almost the same as if he was not connected at all...

Without knowing the IP address of the mail server there isnt much we can do...
But try to configure missing stuff if you have some help from your IT network team
You will need to configure 2 files:

Code:

/etc/resolv.conf
/etc/nsswitch.conf

Can you see if they exist and what they contain?

Please Find the attachment files that you require,

nsswitch.conf and resolv.conf

Please tell me how to configure this ,

So your nsswitch file says:

Code:

hosts:      files dns

In other words look for host in /etc/hosts if not try the DNS

And for your resolv.conf
the first line I dont know (I dont use that syntax...)
You have the line nameserver <IP> , You usually have 2...
And what about Domain name line?

Code:

domain   <yourDomain.whatever>

Now returns a not known that make us seriously doubt on the DNS...
What happens when you ping the name server?

Sample of working nslookup output:

Code:

n12:/home/vbe $ nslookup www.unix.com
Server:         XXX.YY.ZZZ.60
Address:        XXX.YY.ZZZ.60#53

Non-authoritative answer:
Name:   www.unix.com
Address: 4.59.125.171

Please check this,

Code:

[root@edms032~]# nslookup edms032
;;  connection timed out ; no servers could be reached

Yes thats the point...
I wanted you to ping your given name server: 10.66.62.30
Because at this stage we have to get your server out of his isolation...Unless its the will of your IT services...

10.66.62.30 ip not pings,what will I do the next step.
