Introduction
============

nprobe is a software NetFlow v5/v9/IPFIX and nFlow probe that allows to turn a PC into a NetFlow probe.
It has been designed to be compact, easy to embed, an memory/CPU savvy.

Mandatory Packages (Ubuntu/Debian)
==================================
In order to compile nProbe on Linux you need some mandatory packages/tools. Below we list those
needed on Ubuntu/Debian platforms

# apt-get install build-essential bison flex linux-headers-$(uname -r) libtool automake autoconf subversion libpcap-dev wget

Build Steps
===========
./autogen.sh
make
sudo make install


NetFlow v5
==========
This is the default flow export format.


NetFlow v9
==========
In order to enable NetFlowV9 it is necessary to use the -T flag that defines the template format. For instance:
'nprobe -V 9 -T "%PKTS %BYTES %TOS %IP_SRC_ADDR %IP_DST_ADDR"  -n 127.0.0.1:2055'. For the list of all supported
fields type "nprobe -h". You can visualize the generated flows using a recent version of Ethereal (www.ethereal.com).


IPFIX
========
In order to enable IPFIX it is necessary to specify -T (as for NetFlowV9) and -V 10.

Example of Collection Filtering
=============================
nprobe -b 2 -n none -3 2055 -i none --collection-filter as1235 --collection-filter "\!as1234" --collection-filter "\!192.168.0.1/24"
