how to assign a host name?

Mountain · 11-07-2007, 04:35 PM

My prompt says:
root@none:~ #

I assume "none" is my host name. How do I change that? Thanks

You can edit /etc/hostname (or /etc/HOSTNAME) and add something like

Code:

myhost.mydomain

Sometimes setting up the hostname is done in /etc/sysconfig/network (or /etc/sysconfig/networking) e.g.

Code:

HOSTNAME="mybox.mydomain.com"

my etc/hostname file contained the text "none" so I edited it and changed it to "dallas". However, my prompt is still the same:
root@none:/etc #

Any idea why "none" still shows up in the prompt?

Did you reboot the system when you made the changes?. By the way, what distribution are you using and can you please put it in your profile. This will help you get responses and answers that are relevent to your distribution.

Did you restart the network service?

If you are looking for the real easy way and don't know how to access the command line go to System at the top of your GUI and go to Administration, look for Network. There will be five tabs (depending on your Distro it could be a little different) and locate the one that says DNS and enter your host name. The tab next to that one should be called Host Name, select it and enter in your ip address as 127.0.0.1 (unless you set your machine with a static IP), enter the same host name as you did on the DNS tab and then enter the aliases localhost. You will now need to click back to the main/first tab and click activate. It will go through a short process. Once that process is finished re-start your machine. You don't have to reboot the system if you know how to restart the system VIA the GUI but I would recommend a reboot.

No. How do I do that?

I looked up man ifconfig, but I think I'm off track with that...

I don't have a GUI. I have Ubuntu 7.10 server installed at Linode.com. I'm connected via SSH.

to restart the network service on Ubunu try (at the command line)

BEFORE YOU PROCEED:
this will drop your connection, you will have to reconnect.

as the root user do type this:
/etc/init.d/networking restart

Rebooting solved it. I also updated my profile. Thanks.
