NAME

  hostid - Sets	or displays the	identifier of the local	host

SYNOPSIS

  /usr/sbin/hostid [hostname | hexadecimal_number | internet_address]

DESCRIPTION

  The hostid command displays the 32-bit identifier of the host	as a hexade-
  cimal	number in host standard	byte order. The	identifier must	be unique
  across all hosts and is commonly set to the Internet address of the speci-
  fied host.  The superuser can	set the	host ID	by specifying a	hostname,
  internet_address, or hexadecimal_number argument.  The identifier is stored
  in network standard byte order.

EXAMPLES

   1.  To display the identifier of the	local host, enter:
	    $ hostid

	    0xc009c803

       The hostid command displays the identifier of the host as a hexade-
       cimal number in host standard byte order.

   2.  To set the identifier of	the local host to the local Internet address,
       enter:
	    $ hostid 555.5.55.555

       The hostid command converts the Internet	address	to its hexadecimal
       equivalent, and then sets the local host	to this	address.

       Note that the sample Internet address in	this example, 555.5.55.555,
       is not a	valid Internet address and would cause hostid to return	an
       error.
