What about Bittwist? http://bittwist.sourceforge.net/

I have an application where I actually want to "replay" netflow traffic. The problem is that the NetFlow packets have real absolute timestamps in them, which means that if you replay the traffic, it doesn't do you much good unless you want to pretend you're at a time when the traffic was captured. (which is not part of my application) I have looked for a netflow replay tool, and I've found a couple of ones that sort-of fit the bill: nfdump will replay the packets, but it won't slew the timestamps. There's also a couple of tools (canine is the best) which do anonymization, which might involve playing with timestamps. However, neither of them do what I actually need, which is to replay netflow as if it were happening live NOW. In other words, take the first timestamp, compute a delta from "now" to that timestamp, and add that delta to every single timestamp you replay. I'm not opposed to diving into nfdump and adding that feature (hey, this is what open source is all about), but I'd rather see if anyone has a tool that already works. Options? (please: don't send me a link to some web page you found by typing "netflow replay" into Google; I already read all those, and while I appreciate you trying to be helpful, I'm hoping for someone who has experience with a tool to tell me "this works.") If you haven't looked at a lot of Netflow tools, there's an excellent resource list (and meta pointer list) at: http://www.switch.ch/network/projects/completed/TF-NGN/floma/software.html Thanks for any help! jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 [EMAIL PROTECTED] http://www.opus1.com/jms _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
