Hi Folks,

I'm using tethereal to analyse some largeish dumps of a mixed
IPX and IP site (with some NCP over IP).

When I run:

    tethereal -r data.dmp -R "not frame" -z io,phs > summary.txt

I get counts for IP and IPX frames and bytes.

I further analyse the IPX traffic in various ways based on the
results of a 

    tethereal -r data.dmp -R "not frame" -z conv,ipx | sort -r -n -k 9

Essentially all of the IPX traffic counted in the first command is
present in the conversations listed in the second.

However when I run:

    tethereal -r data.dmp -R "not frame" -z conv,ip | sort -r -n -k 9

only about 20% of the total IP byte count listed with "io/phs" is
listed in the conversations listed with "conv,ip".  The volume of
data is too small to be sure, but I think the NCP part of the
conversations are not being included in the "conv,ip" counts.

Can anyone clarify how I can identify the missing 80% of the IP
traffic?

Cheers, Dieter.
