Now I've done some tests with racluster.conf and I am not less confused unless there's a bug in here somewhere.

## racluster.conf ##
RACLUSTER_AUTO_CORRECTION=yes
filter=""              model="saddr daddr proto dport sport “
## racluster.conf ##

#  /usr/local/src/Argus/argus-clients-3.0.8/bin/racluster -r /tmp/ratest  -f racluster.conf -s+trans 
         StartTime      Flgs  Proto            SrcAddr  Sport   Dir            DstAddr  Dport  TotPkts   TotBytes State  Trans 
   09:04:56.941624  e           udp          100.0.1.1.42461    <->          100.0.2.1.59307         2        139   CON      2

So why does options in racluster.conf work differently from those given on the command line?
