Re: [foxboro] Node Bus "Sniffer"

Ethereal is a good general-purpose sniffer, and free (www.ethereal.com).  I
think there's even a port for Solaris on sunfreeware.com.  Of course, all
you'll get is packet capture, and statistics, as I don't think it has a
decoder module for Fox I/A nodebus (but it does for just about everything
else :).  If yoiu want the weighted traffic graph thingie that the newer
Network General products provide, there's one out there called Tvark
(tvark.com, also free), but I haven't used it.

Whether these are better than the original NG Sniffer (tm), I don't know.
But they are certainly more accessible to me from a cost standpoint.  Now,
if only Invensys would publish some protocol details (hint, hint), maybe
someone would be inspired to write some decoder plug-ins <g>.  Seriously,
I'd like to see this happen, for everyone's benefit.  Some nodebus-related
system problems here (not in my plant, fortunately) underscored the fact
that not very many people know what is really happening on the nodebus --
including those that work for Invensys.

Has anyone had any experience with Network Assoc. Sniffer Pro product for
"sniffing" the LAN / node bus.  Are there better or cheaper products out
there?
