 * This routine creates a packet to type AUTH_MSG_DIE which is sent to

 *
 * It takes a string "a_name" which is sent in the packet.  A pointer
 * to the packet is returned.
 *
 * The format of the killer packet is:
 *
 * type			variable		data
 *			or constant
 * ----			-----------		----
 *
 * unsigned char	KRB_PROT_VERSION	protocol version number
 * 
 * unsigned char	AUTH_MSG_DIE		message type
