   Do you try to get data from a Cisco NetFlow _and_ an argus source at
   the same time ? If yes I don't think this is possible as stated by
   the error message you get (please correct me if i'm wrong)

   The way to get netflow and argus data are mutually exclusive: with
   neflow source you bind on a udp local port waiting for udp datagrams
   sent by you netflow source, with argus source you connect to the
   remote tcp socket of the argus server (kind of push vs pull, well not
   really but you get the point)

   The -C flag indicates to ra() that you bind on port 9995/udp
   listening for netflow input (change the port with -P). All you have
   to do is to say to your favorite netflow generator to send the
   netflow data to your box (here localhost as it seems)

   I'm afraid i'm a bit confusing - lack of coffee here too :p
