[SOLVED] Changing Hostname

[griffinmt]

I have three 'cloned' systems (F17 Server with Gnome) running in a VirtualBox environment. After cloning each, I changed the hostname file and the network IP address info so they could be run at the same time. In general, this seems to work.
But not all is correct. For example, if I launch a terminal session, my prompt is in the form of

username@newnode ~$

but the title of the terminal window reads as

username@oldnode:~

So the system still has a record of the old node name laying around somewhere that I need to find and change.

Can anyone point me in the right direction?

TIA

Did you set the hostname using the hostname command?

Fedora 17 and below store the hostname in /etc/sysconfig/network (and also might be in /etc/hostname) and you can manually edit the file and change it there, but it's preferred to use hostname to set it.

su -
(root password)

hostname newhostname

Edit:
Note, you may need to reboot for everything that gets the hostname to get reset and get the new hostname.

There is no 'hostname' file. Maybe you mean .... /etc/sysconfig/network


So first, edit
sudo gedit /etc/sysconfig/network
HOSTNAME=...
line.

Next you need to remove all the old DHCP network leases, since these may contain the name too.
sudo rm -f /var/lib/dhclient/dhclient*.lease

Then reboot.


Something changed in the network config in F17 that can cause the system to take it's network name from the dhcp lease, and the dhcp lease will retain the name from an old lease.

Thanks for the responses:

I did use the hostname command to change, and I am using a static ip address to boot

Just finished file scan looking for any file containing my old node name and did not find anything.

It was there in /etc/sysconfig/network also. Too bad hostname command didn't do the whole job.
Thanks for the help.

hostame command is meant to ONLY change the current name.
It has nothing to do with bootup config.

Your hostname should appear a zillion times under /var - your scan-fu is inferior.
