hostname changed

esgaroth · 08-20-2007, 09:52 PM

somehow i think my computers hostname has been changed. I am using fedora 7. When I turn on the computer I am prompted to login to laptop instead of localhost. So that after I log on it says username@laptop. I dont think I changed anything that would have anything to do with the computers hostname, and I dont really know how to change it back. My hosts file only contains the line 127.0.0.1 localhost.localdomain localhost.
/etc/sysconfig/network says the hostname is localhost.localdomain and /etc/hostname appears to be blank.

Have you rebooted your machine?

yes, several times.

So does anyone know what I need to do to fix this? Is there any other information I should provide that would help?

have you tried changing the /etc/sysconfig/network entries? replace laptop with the hostname you want, then reboot

I don't think you need to edit any files to set the hostname. The command 'hostname' is there to do that. Try 'man hostname' to see what it'll let you do.

True; however what the hostname command does is not saved between reboots, hence the need to put the value into /etc/sysconfig/network.
Startup scripts are written in a way that hostname is called with the name you put in the config file.

That's what the --file switch is for I guess.

esgaroth · 08-22-2007, 09:54 PM

Well as I said in the original post the /etc/sysconfig/network file says the hostname is localhost. Here are the actual contents of the file:
NETWORKING=yes
HOSTNAME=localhost.localdomain

your system might be picking up the name from the local DNS.

replace HOSTNAME=localhost.localdomain to HOSTNAME=mylaptop.intra.yourdomain.com or any host you prefer, save then reboot. edit it using vi.
