racluster for DNS

Hello guys,

I'm using racluster for aggregate some http flows, but I don't want
aggregate DNS flows. By default, racluster aggregate all dns flows, like
this:

% racluster -r cleaned_dump.argus

udp    192.168.100.106.1041     <->      192.168.100.1.domain        8
  1041   CON


For aggregate http, I just used the following filter (with -f option) and
everthing is O.K.:

filter="tcp"            model="saddr daddr proto dport sport"
I've tried something like this for DNS, but is not working (returns
ArgusParseAggregator: ArgusNewAggregator returned NULL):
filter="udp and dst port 53"           model="none"

If I don't use the option -f with racluster and pass "-m none" to the
program, all DNS are correct, but the http flows isn't aggregate.

192.168.100.106.1041     <->      192.168.100.1.domain        2        240

192.168.100.106.1042      ->        A.http          7        714

192.168.100.106.1041     <->      192.168.100.1.domain        2        224

192.168.100.106.1041     <->      192.168.100.1.domain        2        368

192.168.100.106.1041     <->      192.168.100.1.domain        2        209

192.168.100.106.1042      ->        A.http          2        114
I read the racluster manual and tried some configs but I couldn't find a
solution for this. Probably I miss something.
Any suggestion is wellcome.

Tks.
