Hi, For the last ten years or so, I've defined the short hostname in /etc/hostname and the FQDN in /etc/hosts. Now I wanted to double-check this information, which eventually led me to this page: * https://serverfault.com/questions/331936/setting-the-hostname-fqdn-or-short-name Now I admit I'm even more confused than before. Is there some reliable piece of information on this subject for CentOS ?
