Hi,

I have just released fping 4.0-rc3

Please help me test it: http://fping.org/dist/beta/

Since 4.0-rc1, the following has changed:

  * INCOMPATIBILE CHANGE: discard late packets

    fping will now discard replies, if they arrive after the defined timeout
    for reply packets, specified with -t. This change is relevant only for the
    counting and looping modes, where the measured times should now be more
    consistent (see github issue #32 for details).

    To prevent loosing reply packets because of this change, the default
    timeout in counting and looping modes is now automatically adjusted to the
    period interval (up to 2000 ms), but it can be overriden with the -t
    option. The default timeout for non-looping/counting modes remains 500 ms.

  * INCOMPATIBLE CHANGE: no restrictions by default

    fping will not enforce that -i is >= 1 and -p >= 10 anymore, except if
    you ./configure with the new '--enable-safe-limits' parameter.

    The reasoning to removing the restrictions by default, is that users can
    clog the network with other tools anyway, and these restrictions are
    sometimes getting in the way (for example if you try to ping a lot of
    hosts).

  * INCOMPATIBLE CHANGE: default interval (-i) changed from 25ms to 10ms

    The default minimum interval between ping probes has been changed from
    25ms to 10ms. The reason is that 25ms is very high, considering today's
    fast networks: it generates at most 31 kbps of traffic (for IPv4 and
    default payload size).

The full changelog is here: http://fping.org/dist/beta/ChangeLog

Cheers
David
