It doesn't respond "noun" but "(none)"...did you read the man page on the domainname command? If you did, you would have seen that the command pulls NIS/YP domain name...so if you're not running NIS, you won't get anything. Similarly, reading the man page for the hostname command would tell you that it will return the entire FQDN, and typing in "dnsdomainname" will give you just the domain.

Read the "Question Guidelines" link in my posting signature.

Did you not read or understand the previous post??? You were TOLD HOW already.

I can't get anything, this Linux site was more confusing, unlike windows support service. if u have a time please explain me step by step, otherwise give me the reference page. then explain what is man page.

You were **GIVEN THE EXACT COMMAND** to type in...it cannot be more plain; type it in and press ENTER. Man pages are Linux commands that give you the manual for ANY command. Type in "man hostname" and it tells you all about that command.

You again need to read the "Question Guidelines" link in my posting signature, as well as the LQ Rules about text-speak and NOT using it. And if you read the "Question Guidelines" link, you'd see that doing basic research should be the FIRST thing you do before posting. The commands you were given can easily be found with a brief search, as could what a man page is and how to access them. If you feel that Windows is better, then please use it, if it's a better fit for you. We volunteer our time, unlike Windows support, and because of that we expect others to do some research and show some of their OWN EFFORTS, rather than asking others to look things up for them.

How is your domain configured? Your probably not running a NIS server and I assume your actually trying to find its DNS FQDN. Try the command

hostname --all-fqdns

Yep...suggested the hostname command in post #2, along with dnsdomainname, and informed the OP about NIS/domainname also.
