hostid(1)
NAME
  hostid - Sets or displays the identifier of the local host

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

DESCRIPTION
  The hostid command displays the identifier (either a unique hostname or a
  numeric argument) of the local host as a hexadecimal number. The identifier
  must be unique across all hosts and is commonly set to the Internet address
  of the specified host.  The superuser can set the host ID by specifying an
  internet_address or hexadecimal_number argument.

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

	    0xc009c803

       The hostid command displays the identifier of the host as a
       hexadecimal number.

   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.
