A host should be grouped under a specify host group to ease the configuration tasks.

*[Important]* Before begin, the following items should be prepared and ready:

* *host name* - a short name to identify the host

* *alias* - a longer name or description to identify the host

* *IP address* - IP address of the host. *Should not use hostname as it rely on DNS*

* *host group* - the host group of the host

If the host is a not *nix machine, please consult the administrator.
