 > ping PHIPACHP02OPE19 1                               
no answer from PHIPACHP02OPE19

***********************************************

>./check_ping -H PHIPACHP02OPE19 -w 1000.0,20% -c 2000.0,60%
OK - PHIPACHP02OPE19: rta 0.681ms, lost 0%|rta=0.681ms;1000.000;2000.000;0; pl=0%;20;60;; 

Still puzzled

Thanks
