[Ethereal-users] Possible Anomaly in tethereal -z stats system

["Tim Everitt" <tim.everitt@xxxxxxxx>]

I've recently upgraded from 0.10.6 to 0.10.12 and a very useful part of the
tethereal -z stats package that I use to create CSV files for plotting has
stopped working.

I'm using Fedora Core 4 and the Ethereal 0.10.12 RPMs from the
download.fedora.redhat.com website.

The command

# tethereal -r <file.pcap> -z "io,stat,1,SUM(frame.pkt_len)frame.pkt_len"

To get per-second octet-counts has stopped working. It runs ok but does not
match any traffic so produces 0 as output. Other operators are working ok,
e.g. SUM(tcp.len)tcp.len, etc.

On further investigation, use of any "frame..." operator in the io,stat
package fails to match any frames.

Use of frame.pkt_len as a display filter works perfectly.

Can anyone direct me towards the area of code where the parsing and
processing is done so that I can investigate further or does anyone know the
code well enough to check.

Thanks and Regards, Tim Everitt.
