fully qualified name

KINGSLEY_1 — Wed, 04 Nov 2009 11:09:17 GMT

Hi All!

I have an intergrity server with hp-ux 11.23. In the /etc/hosts file i have hammer.mog.gov.gh as the fully qualified name for the server.

When i do "ping hammer" i get a good response. But when i do "ping hammer.mof.gov.gh" it tells me the hosts is unknown.

Can someone help me.

Do you resolve addresses from hosts file first, or do you try to resolve from DNS server first?

Check out your nsswitch.conf and resolv.conf

/2r

In your /etc/nsswitch.conf you might have a default setting for dns lookup first, like this:
hosts: dns [NOTFOUND=return] nis [NOTFOUND=return] files
First dns, then nis, and at last files (eg. /etc/hosts)

If so, I assume this would be more correct for you:
hosts: files [NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return]

If you are the owner of the subdomain

mof.gov.gh

then you should update the corresponding zone of your DNS in order to let others know that you have a fully qualified name.

Otherwise, you will only be able to resolve locally the full name by adding this line to /etc/hosts:

hammer.mof.gov.gh 192.168.1.1

Modify the line to use your real IP address.

Best regards
Horia.

Hi,

lot of confusion between mog and mof. so, if you doing typo (either at command line or at /etc/hosts), then i hope you got it right now.

Else, check your /etc/nsswitch.conf that how is your hostname is getting resolved and change it to files (if you want to resolve it by /etc/hosts).
