+ *                 to this host (as returned by gethostbyname() or
+ *                 gethostbyaddr() and expects one host only to be checked at
+ *                 a time.  Therefore, any packet response what so ever will
+ *                 count as a sign of life, even when received outside
+ *                 crit.rta limit. Do not misspell any additional IP's.
+ * MODE_ALL:  Requires packets from ALL requested IP to return OK (default).
+ * MODE_ICMP: implement something similar to check_icmp (MODE_RTA without
+ *            tcp and udp args does this)
