Can somebody explain a bit on how the extended ping sweep command works and how it works.
So far, all I can figured out is that it will ping the target ip with gradually larger ping sizes..
I'm also looking to see how the df-bit can help in determining mtu size. I know that setting it on means to set the packe to 'don't fragment'.
I have an issue in which regular pings ( all sizes work ) but after setting the df-bit to on, I now see ping packet drops and 'M'' responses. It usually have the dropped packets and M responses when the regular ping latency is over 80ms.. Target ip under 80ms or so have no packet drops or M responses.
Carrier claims this is normal.
I'm specfially am interested in the following area.
Sweep min size :
Sweep max size :
Sweep interval :
Note the link have some explanations but not getting it..
!--- The count 179890 depends on the values of min sweep,
!--- max sweep, sweep interval and repeat count. Calculations are based on:
!--- 18024(high end of range) - 36(low end of range) = 17988(bytes in range)
!--- 17988(bytes in range) / 1(sweep interval) = 17988 (steps in range)
!--- 17988(bytes in range) + 1 (first value) = 17989(values to be tested)
!--- 17989(values to be tested) * 10(repeat count) = 179890 (pings to be sent)
!--- In order to decrease the value, increase the sweep interval or decrease
!--- the repeat count, or you can even decrease the difference between
!--- Minimum and Maximum sweep size. Based on the previous example, the
!--- number 17890 is an expected value and tries to ping 17890 times.
