Thank you for visiting SAP Community to get answers to your questions. Since you're new in asking questions here, I recommend that you familiarize yourself with https://community.sap.com/resources/questions-and-answers (if you haven't already), as it provides tips for preparing questions that draw responses from our members. For example, you can outline what steps you took to find answers (and why they weren't helpful), share screenshots of what you've seen/done, make sure you've applied the appropriate tags, and use a more descriptive subject line. The more details you provide, the more likely it is that members will be able to assist you. You should also make sure you're using all the appropriate tags, so the right experts can find your question.

Should you wish, you can revise your question by selecting Actions, then Edit (although once someone answers your question, you'll lose the ability to edit the question -- but if that happens, you can leave more details in a comment).

Finally, if you're hoping to connect with readers, please consider adding a picture to your profile. Here's how you do it: https://www.youtube.com/watch?v=F5JdUbyjfMA&list=PLpQebylHrdh5s3gwy-h6RtymfDpoz3vDS . By personalizing your profile with a photo of you, you encourage readers to respond.

Hi Prashant,

The correct command is hostname -f OR hostname --fqdn only

You are getting only hostname with the command hostname -f because your setting at /etc/hosts file is not in correct format.

The correct format is -

IP-Address Full-Qualified-Hostname Short-Hostname

If your /etc/hosts file has entry

xx.xx.xx.xx hanasfdev hanasfdev.xyz.abc (Optional : can have list of alias too )

the same command will read the middle term and output will be same as you got.

Check your /etc/hosts . It should be

xx.xx.xx.xx hanasfdev.xyz.abc hanasfdev

Under SuSE you can set the hostname with the following command as root:

hostnamectl set-hostname <new FQDN>

Dear michael.teubner

i am not setting the hostname rather i want to query my FqDN

[MichaelTe]

If the first command responses only with

hanasfdev

then a FQDN is not set on your box.

Hello,

hostname -f

Regards,

Michael
