It is needed to copy the "netflowV9.py" file into "/usr/local/lib/python2.x/site-packages/scapy/layers/" for adding the Cisco NetFlow protocol to Scapy tools.
~$ cp netflowV9.py /usr/local/lib/python2.x/site-packages/scapy/layers/netflowV9.py
~$ cp dosflowsys.py .
~$ mkdir servers # to create the "servers" that contains configuration files for each server to be probed
It is needed to define a configuration file for each server into "servers" directory
An example is given below:
MAX_TCP_CLIENTS = 4000 # maximum number of TCP clients supported by the server
MAX_LATENCY = 100 # maximum acceptable latency
MAX_SYN_BACKLOG = 2048 # backlog queue size
~$ python2.x dosflowsys.py
