Hi

Thanks for your hint.  The output had a error as I
forgot to specify -l in comand line.  The attached is
the right output after I specified -l switch in
command line.

Here is the last part of output:

| gen-id=122    sig-id=19
tracking=dstip=0.0.0.0           mask=0.0.0.0

*****************

It looked like it reads the threshold.conf but can not
suppress the alerts?  Why?

Any help will be appreciated.  I am just too upset
with that.


Thanks,

Peter
