Argus flow direction

Hey Tbh,
racluster.1 does have the ability to ‘correct’ flow records for the direction, and I think that should be the default behavior.  Its possible that the default is being changed (.rarc ??).  Try racluster with the “-M correct” option to see if you can force correction.

There are exceptions for correction, especially when you are processing flow records from different sources.  Do both of these flow records have the same ‘srcid’ ??
Try “-M correct”, if that doesn’t work, generate a data file with these two records in them, and I’ll take a look …

Hope all is most excellent,
