Hi Guy,
Just had a look at ntop, looks like it'll do the job, cheers for your
help.

Using Ethereal for that purpose could be considered equivalent to
sending a sample of your blood to a clinical laboratory for a full blood
chemistry analysis in order to find out whether it's red or not. :-)
You might want to see whether ntop:
http://www.ntop.org/
could do the job - it might be easier to get it to do that, especially
in an automated fashion, than it would be to get Ethereal to do that.
(As the "NTOP - Network TOP: An Overview" paper:
http://www.ntop.org/ntop-overview.pdf
says:
Simple alternatives to network monitoring are packet tracers and
decoders, often-called network sniffers. Examples are tcpdump [Jacobson
et al] and snoop [Sun]. These tools are responsible for capturing
packets from the network and often require off-line analysis tools to
correlate captured data and identify network flows. Sniffers usually
provide details on packet activity and lack information on the network
as a whole [DeriSuin99]. Protocol analyzers, such as Ethereal
[Ethereal], typically focus on the content of single network packets and
not on global network activities. These solutions lack high-level
support to management activities.
