name change in /etc/hosts and reboot doesnt change name

aussieaubs · 06-25-2009, 09:33 PM

hi ive changed my /etc/hosts file to a new name and when i reboot Centos 5.3 the logon splash screen still shows the old machine name. I followed the existing format of the hsots file to change the name to a new name??

is /etc/hosts the only place to change the host name?

TIA
A

Nope, it's not. That's just for a mapping of names to IPs if
they're not in DNS.

To change the hostname edit /etc/sysconfig/network

Cheers,

TO change he host name u have to follow three steps
1)put the entry in /etc/hosts
2)put the entry in /etc/sysconig/network
3)run this command hostname with giving new hostname for example: if u have new hostname like www.linuxtest.com
then rum this command
hostname www.linuxtest.com

Hi,

I'm running CentOS too, the correct place to change it is in /etc/sysconfig/network.
