Hello, I have been searching for a solution that collects/duplicates NetFlow traffic properly for a while but i couldn't find any. Do you know any good unix alternative to ntopng, flowd, flow-tools? nprobe of netflow seems to be the closest one to fit my needs but i want to see if there are any other solution. My goal is to centralize NetFlow traffic into a single machine and then proxy some flows to other destinations for further analysis Best Regards, Sami
nProbe is what you want, it’s another product from NTop. http://www.ntop.org/products/netflow/nprobe/ <http://www.ntop.org/products/netflow/nprobe/> - Tim

Actually: samplicate is more all-or-nothing as far as I'm aware. So it could proxy a full set of flows, but the "some flows" part of your request I'm not so sure about.

samplicate is very good, been using it for 6 years for netflow duplication using botth the spoofing and non, depending on the sensor's needs if it needs to retain the source ip or not. On 6 June 2017 at 20:39, Dobbins, Roland <rdobbins@arbor.net> wrote:

You may want to check out the SiLK netflow capture and analysis tool suite. Look in particular at it's SiLK Administrators Tools section which provides extensive flexibility for manipulating netflow exports. The analysis tools are quite good too. http://tools.netsa.cert.org/silk/silk-reference-guide.pdf Joe "NANOG" <nanog-bounces@nanog.org> wrote on 06/06/2017 05:43:46 PM:

We use pmacct with it's tee plugin - it gets the job done beautifully and it's a one-liner config. https://github.com/pmacct/pmacct/blob/master/CONFIG-KEYS On Tue, Jun 6, 2017 at 2:43 PM, Sami via NANOG <nanog@nanog.org> wrote:
