A Result of 0 and below 20ms is okay,negatives are faults.

I only get negative values. I only get zero if I ping my localhost or my own IP. Anyone else?

Correct me if I am wrong but pinging your 'localhost' or own IP is the equivalent of a TCPIP local loopback and therefore 0 would be correct?

Hello,

0 means a good ping reply but with a short delay.

Only negative values should be errors (ie unreachable address or no network).

Positive or null value mean 'reply time' in milliseconds.

Rings , your snippet works anyway.

Thanks a lot. I only get negative values by trying to ping google.com on 216.239.55.100.
