I have the real NetVisualyzer package (including netsnoop, netlook, analyzer)
running on an SGI workstation. It is a great package to watch networks in
action. My SGI machine is the only SGI on this research campus watching
the traffic of about 300 Suns... I had to buy the SGI workstation to
be able to run this great package. I never found something as good for the
money running on a Sun.

I just don't understand why SGI don't port this package to Sun and sell it
with a good profit?

Again, a very good package to see and debug networks, no statistics or snmp
in version 1.0 but I heard it is comming.

Clem.
