[Gllug] Pinging a machine that is down

[Alain Williams]

I have just rebooted a customer's machine (to run a new kernel).

I left a ping running so that I could login once it had rebooted.

I noticed that the ''Destination Host Unreachable'' appear in 3s with the one before
the first of the 3 missing. Eg in the sequence below 100,101,102 all appear at once,
there is then a pause before 104,105,106 appear.

Anyone any idea why it behaves like that ?
