Sometimes things are in the most obvious place, yet you miss them :) Now, the manual pages says for -a I should give values greater than 1 if bandwidth*delay is high. I'm on a swithed FastEthernet, so bandwidth=100Mb/s and delay is around 0.2 ms of ping roundtrip time. As for -r it says it should be used when there are many "fragments dropped due to timeout"; yet I see almost none. Do you have any suggested values to start with, before I make random experiments? bye & Thanks av.
