On CentOS (5.x) I have a VPS that has hostname set to "olddomain.com", at least this is the domain I am getting when typing "hostname" command.
I want to change it to 'localhost.localdomain' because I think it is more generic and reliable.
localhost.localdomain already exists in these files: /etc/sysconfig/network AND /etc/hosts
NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=localhost.localdomain GATEWAY=95.xx.xx.xx
# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6
So next I tried these commands:
hostname -v localhost.localdomain
"hostname" command now returns this new value. But after restart it changes back to olddomain.com or at least this is the "hostname" command returns.
Anything else to edit?
