The name of your machine, as it will be referred to by things that look it up in [DNS] and hosts(5).

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>.

Compare [FQDN].
