Hi Timo,

Oflops is at best in an alpha state right now, although I've been
working with a bunch of people to improve it.  Thanks for your
patience with it.

About your questions:

- the "found unmarked probe" message is harmless and you can ignore
it.  All it means is that oflops has found a packet that is not part
of the test.  This could easily happen if your switch is sending STP
discovery messages or any other type of probe.

- about the segmentation fault, I haven't seen this.  Are you able to
replicate this behavior running with a different switch (for examle,
OVS or the stanford reference switch)?  Knowing how to replicate the
problem could help with debugging it.

Thanks,

- Rob
