--- Netflow-IPv6 EFT ---
IPFlow Presentation
IMPORTANT: IPFlow information has moved to a new WEB site.
This collector has been developed by UTC
(University of Technology of Compiegne, France)
mainly for its internal use.
It is provided without any warranty, with the hope it will be useful.
This is not a commercial product, essentially developed during
free time.
It can be used to do some tests with Netflow-IPv6, since it supports
Netflow v9 and has IPv6 capabilities.
If you are interested by this tool, you can send feature requests,
ideas, bug reports, ... to the author.
Any feedback will be appreciated :)
