Re: [OpenCALEA] Recent updates

See attached conf file (basically make /home/calea the default folder for
everything)

I issue the following secuence of commands (so far, I am avoiding the
controller interface)

controllerd -f /home/calea/opencalea.conf &
df_collector -f /home/calea/opencalea.conf &
lea_collector -f /home/calea/opencalea.conf -b 127.0.0.1 -t li4 -f lf4  &
tap -f /home/calea/opencalea.conf  -x 001 -y 001 -z 001 -c pcap host 1.1.1.1
&
and (Killing the previous tap process)
tap -f /home/calea/opencalea.conf  -x 002 -y 002 -z 002 -c  ias-cmc host
1.1.1.1 &

Two folders were created in /home/calea  001 and 002 with  the following
files: CmC ,CmII  , and Log

I noticed that the CmC file remained empty for both tapping process
I have the following questions:
1) Am I missing something since the CmC files do not show up any content?
(both lea_collector files show content, though)
2) Is there an easy way/tool to verify the resulting files format?
3) Since I used -c pcap with tap, I was expecting that I could read the CmC
file with tcpdump, is this correct?

Regards,

Mario Antonio
