hostid(1)
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
  hexadecimal number in host standard byte order. 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 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
       hexadecimal 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.
