Hostname changes after reboot

spg001 · 08-14-2003, 10:08 AM

I have only been using Linux for a day now - thought it was time to wean myself off of Windows. Well, I've figured out how to change the hostname of my machine, but any time I reboot the hostname reverts to 'none'
Is there any way I can prevent this from happening?

You need to edit the /etc/sysconfig/network file.
Add your new hostname on the HOSTNAME line.

that file contains the following:

127.0.0.1 localhost

if I want to change the name that shows up when I open a terminal is this where to do it? and if I am using dhcp to get an IP address would I add another line:

127.0.0.1 mandrake-linux

or would I have to use a different IP other than the localhost name, or do I need to put an IP address in at all??? this is the part that confuses me. If I don't have a static IP how can I put a hostname in there?

jgallas, you can also add extra hostnames in /etc/hosts
For example, the loopback address line (the first line) should look like this:

Code:

127.0.0.1       localhost.localdomain   localhost

If you want to add extra hostnames, append them to the end of the line

Code:

127.0.0.1       localhost.localdomain   localhost mandrake-linux

It was so simple that I couldn't get it

how do I get it to change the host name in the terminal:

right now it says.... root@win2k-0

I would like it to say root@mandrake-linux

I know the hostname is set so other machines can see it right, I just want my own machine to know it's correct name as well or will this be accomplished after modifying the hosts file and rebooting?

You need to edit the /etc/sysconfig/network file.
Add your new hostname on the HOSTNAME line.

To take effect, you will need to reboot.
Or
at the command line, type: service network restart
