Hi,

we are afraid to loose packets while doing a capture with ethereal
(or tcpdump) without noticing it.

We are thinking about modifying a network card driver in order to
write packets directly to disk (without running ethereal/tcpdump)
and then read and evaluate the raw data using ethereal after the
measurement.

If someone on this list had similar ideas I would be thankful to hear
his experience/advice before we start work. Also I would welcome
comments on the performance of ethereal during capturing (i.e. is
our approach unnecessary because ethereal will definitely not loose
any packets at all?)

Thanks & Regards,
Johannes
