Can you provide a link to "Shadow"?

Thanks.

Actually, there's a pretty good tool out there to do what you want:
Shadow. We use it to do the captures using machines much like has been
described; Using several data collectors, they feed their captures to a
central server once an hour. We capture only the headers, but we keep a
4-day backlog. That way, if some problem shows up, we have historical
data to review. We use the internal Shadow search, which gives us a
TCPDUMP-style report, or we can extract out and use Ethereal.
Alternately, if we need a full-packet capture, we temporarily take over
the sensors, get our capture, drop it on our machines and use Ethereal
to review.

It's not a system command, it's a command (shell script, actually) in
the source directory of Ethereal (and of many other UNIX programs).

So, from the top-level directory, run

        ./configure

Only if you're using the current CVS version of Ethereal, as the
configure script is built by autoconf from configure.in, and is not part
of the CVS tree.

If you've downloaded a standard source release of Ethereal, you don't
need autoconf (unless you'll be changing configure.in, acinclude.m4,
etc.).

This was discussion about this very recently with the subject line
"Three Big Problems" your question was pretty much problem #3
http://www.ethereal.com/lists/ethereal-users/200210/msg00220.html

But the time the conversation ended Justin was still in thinking mode
but with great things planned. I wonder how he got on.

Justin ... ?

I am trying to get specs together for a machine that will be able to
capture all the packets going over a 100 Mb Ethernet line. I will be
logging all the data to drives and then nightly when the line is slow,
take the captures and run Ethereal on them.

How much machine will I need to keep up with a busy 100 Mb line? Single
processor at 3.06 GHz, dual CPU? 15k RPM SCSI drives? Is there anywhere
I can go to help me figure out how fast the machine has to be?
