NAME    [Toc]    [Back]

     hostid - set or print identifier of current host system

SYNOPSIS    [Toc]    [Back]

     hostid [ hexnum | hostname	]
     hostid -h hostname

DESCRIPTION    [Toc]    [Back]

     The hostid	command	with no	arguments prints the identifier	of the current
     host in hexadecimal.  This	numeric	value is expected to be	unique across
     all hosts and is commonly set to the host's Internet address.  The
     super-user	can set	the host ID by giving an argument that is a
     hexadecimal value or a hostname.  With the	-h option, the argument	must
     be	a hostname.  If	the argument is	a hostname, hostid sets	the ID to the
     name's Internet address listed in /etc/hosts.  Hostid sets	the exit
     status to 0 if it successfully changed the	host ID	and to 1 if not.  The
     script /etc/init.d/network	uses hostid to set the ID during system
     startup to	the Internet address of	the hostname found in /etc/sys_id.
