I just modified `ping' to output standard deviation in addition to the other statistics. Does anyone out there think that this would be useful in the general case? This gives output like: --- lanrover.lcs.mit.edu ping statistics --- 81 packets transmitted, 81 packets received, 0% packet loss round-trip min/avg/max/stddev = 2.220/5.378/67.712/10.643 ms (As you can see, there's an unfortunate amount of jitter in my network.) It does increase the size of the ping executable a few K since we have to link against the math library. -GAWollman -- Garrett A.
