Every decent [TCP/IP] connected machine has at least one host name (you'd be hard pressed to do anything on [Linux] without having one!) Some will have other aliases that point to the hostname. Hostnames must be unique on a network, except in the case of clustering or failover (which is a bit trickier than it sounds) - in which case you tend to have unique hostnames on the machines, and ''another'' hostname which points to a RoundRobin lookup for them. |

The machine you are connected to now has a hostname of <tt>hoiho</tt>. You're probably accessing it through its alias <tt>www</tt> however. (<tt>hoiho</tt> doesn't need to know about that alias at all, except in the case of the WebServer for NameVirtualHosting.) |

The hostname is set at boot by the hostname(1) command, which reads it out of a file; usually <tt>/etc/hostname</tt>. |
