IPAC-NG
* Looks good, but list of IP addresses and ports needs to be
hardcoded before hand. Ok for small networks, not
large/variable networks.
IPFM
* Doesn't seem to work on ippp0 port.
* When run on internal interface, probably tracks internal data
as well as externel (not sure).
NETRAMET
* Isn't in Debian, but I think this would be easy.
* Licensed under an ancient Emacs license (is this really valid?
Why not the GPL?)
* No tutorial for beginners.
* Looks nice and sophisticated compared with the other options.
* Australian mirror is years out of date (according to timestamp
on files).
* http://www2.auckland.ac.nz/net/NeTraMet/
CISCO
* "Pick up a cheap Cisco router from a failing ISP and export
its flow statistics?"
* All my ISDN DOV data goes through a CISCO router at the remote
end, and I have access to it, but I don't have a clue how to
use this flow stuff, or what is capabilities are...
IPAUDIT/IPAUDIT-WEB
* doesn't seem to be in Debian. Its name sounds good ;-)
* http://ipaudit.sourceforge.net/ipaudit-web/index.html
* looks good, will try it latter.
