Changing the host name on a linux box

[Onur]

This is a simple process ... But again, probably you dont know it since you are looking for it.

2 Places to Change:

/etc/sysconfig/network, Edit the

HOSTNAME=.

This will be available even after a reboot.

A quicker way - Edit

/proc/sys/kernel/hostname.

But that won't be saved when you reboot.

Thank you for such nice sharing !

Isn't this distro-specific. I mean the HOSTNAME even when exported once is not remembered in some distros after reboot...

Is there any universal way which will work irrepective of the distro being used ?

since different distro's place the hostname file in different places, on a ubuntu setup, it is /etc/hostname file to alter.

you could do a grep -R "your hostname" /etc which should find out where the file is.
