I have Netflow V9 being sent to a server running Ubuntu 14.04. The data is communicated on port 2000 (the default for Netflow). However nothing appears to be listening on that port. (nothing shows port 2000 when I run 'netstat -ntlp'.
I have a few rather-noobish questions:
What service should I configure to listen on port 2000? Where can I find this raw data? Is it by default being written to a file?
The point of my project is to fan out the netflow data, with some of it being downsampled prior to being forwarded. Our Cisco Nexus can fan out and downsample, but my understanding is the Nexus 7000 can't fan out and downsample just one exporter, it's an all-or-none as far as downsampling goes.
If I can provide any additional info, please let me know. Thanks for any and all help.
