not smooth reasons:
A physical line in question / physical host was closed
b network security devices to prevent the ping function
c virtual host NIC address is set the correct
d virtual NIC (vmnet8) have not turned on and configured correctly
e web hosting network service is close

SSH service port number --22
cause of the failed connection:
