I'm having a right headache through this happening all the time.

How can I make it say this at the prompt?

[michael@bigbadboy michael]$ or

[michael@localhost michael]$

instead of this

[michael@x1-6-00-02-e3-0b-39-3f michael]$

Here is what my hosts file has in it at the moment

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost x1-6-00-02-e3-0b-39-3f


I added the x1-6-00-02-e3-0b-39-3f as one way of trying to fix it.

/etc/sysconfig/network has this

NETWORKING=yes
HOSTNAME=localhost

I'm desperate to get rid of that prompt and also on the login screen.

Anyone able to advise me please?

Give your computer a regular hostname. You can use the hostname command as root to change it. You need to log out of KDE after changing th e hostname.

Thank you.

I've tried that and it does change it, but if I reboot the computer, it's back to that x1-6-00-02-e3-0b-39-3f again

Is there a way of changing it to make it permanent?

Have you taken the x1-6-00-02-e3-0b-39-3f off the localhost line in /etc/hosts? You could add the line:

x1-6-00-02-e3-0b-39-3f bigbadboy

to your /etc/hosts file to get the hostname set permanently, I think.

Thanks. I'll try that. Looks promising.
