Hello,
Using NNA 2.4.0 :
We've a CISCO 3750, which doesn't support Netflow, and we want to monitor it through NNA.
We configured into CISCO 3750 a spanning port (which we'll name "spanX" for the rest of this discussion) taking a copy of unique port.
If we connect the "spanX" port with a windows machine and used Wireshark, we're able to see traffic captured : it works fine.
We installed a CentOS linux server whith 2 network cards : one connected to LAN (eth1) and a second to "spanX" (eth2).
We disabled SElinux on this server, we installed fprobe on it : following the instructions you provide on your documentation and taking in care the authorizarion file.
We ran the fprobe as follow : fprobe -i eth2 <NNA_IP>:9915
nothing happens and we can't find the process running when we execute : ps -ef | grep fprobe
Final result : we're not able to convert the traffic coming from "spanX" into Netflow to use it with NNA.
Any suggestion please ?
Thanks & regards

Re: Converting network traffic to netflow using fprobe
fprobe should log to the /var/log/messages file. Try starting it again and check the messages file for any errors to see why it is not running.

Hello
I found the problem : it was on the command.
I had to put em2 instead of eth2.
Everything works fine with this configuration.
