change host name in Fedora16

[PiElle]

To change the computer name in F16 is sufficient to edit:
1) /etc/sysconfig/network;
2) /etc/hosts?
It's correct to add the new hostname to the /etc/hosts file, leaving the localhost name in there as well?
Do I have to edit other files to avoid problems?

afaik, you may simply change the first line of /etc/hosts:

There is a command for that. It's called hostname.

hostname - show or set the system’s host name

You really don't want to replace the localhost name with NEWNAME as you showed, sea..

What you would want is more like this:

127.0.0.1 localhost.localdomain localhost NEWNAME

I set my /etc/hosts file as follows ... (where pc2 is the NEW computer's name)
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 pc2
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 pc2

that is the correct way to put the new hostname in your /etc/hosts file.

You always want to keep the localhost and localhost.localdomain in there as there are applications that depend on that name being in there.

as far as the actual changing of the hostname, I would do as PabloTwo suggested above and use the hostname to change it. You can manually edit the /etc/sysconfig/network file, and it should be enough, but to be safe, I would use the hostname command

I edited manually the /etc/sysconfig/network file, changing the previous name in the "HOSTNAME=pc_name" string (this is valid for other Linux distributions too).

But, to say the truth, I've noticed that in a (absolutely) fresh installation of F16 the /etc/hosts file is like this:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

I mean: it doesn't contain the computer name! In this case, the computer had been named pc during the installation process ...

Edit this file /etc/hostname

Hi Salem,

In Fedora 16, that file doesn't exist.

You can use hostname command to set a temporary hostname, until the next reboot.

A permanent change needs to made in the /etc/sysconfig/network file as mentioned above.
