hostid

hostid(1)						      General Commands Manual							 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

       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.  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.
