if you can provide me some packets I can use for reproducing the bug, I
am willing to fix it. Please provide me a pcap file with full packets
and I will investigate

Hello again,
is there any sort of output that I can produce that can be useful to the
developers? (strace maybe?) . I've tried a few things but I'm still
getting segfaults. Could I be affected by the demo version?
regards,
Yannis

could you try to run nprobe on a physical interface instead of a bond one?

Hey all,
We've recently started to try out probe/ntop for netflow monitoring and
we're using the demo version until we've set them both up in an
acceptable way :)
I've noticed that nprobe segfaults quite a lot. Is there something
obvious I'm missing here?
relevant info:
