Possible bug on output of racluster

Hey Ricardo,
Sorry for the delayed response. What version of the clients are you using?

It is always good to inspect the data that is in the intermediate file, in order to
see where the breakdown is.  Are the contents in your ra-output.argus file

Be sure and include the 'proto' when you are interested in aggregating by ports,
as the port numbers are somewhat meaningless without the proto that specifies
them.   The newer clients, like argus-clients-,  should do this automatically.

If you are still having a problem, consider sharing the files so I can figure out
what is going on.
