rafilteraddr issue

Hello all,

I'm attempting to use rafilteraddr and I must be using it wrong, but there 
isn't any authorative documentation on it.  I'm using argus-clients-3.0.2 
from http://qosient.com/argus/dev/ from the tarball dated 1/26/10.

Right now I'm just attemping to take a file and filter it to get a smaller 
subset of records.  My source file has only a handful of records and 
contains my targeted IP.

I'm running:
rafilteraddr -f filtertest.txt -r /data/argusinput -w /data/argusoutput

with a file containing my one target address.  If I try this command with 
the one line '192.168.1.1' or '192.168.1.1/32', I get the records I 
expect.

If I try '192.168.1.0/24', I get no records back at all that I should.

If I use -vf to invert my results, I get similar behavior.  Filters using 
the /24 are ignored, but entries with the /32 are processed correctly.

If I put more than one record in my filter list, mixing /24s and /32s, the 
/24 records are ignored and the /32s are processed correctly.

Could something be parsing the file wrong?  or am I doing something wrong?

Thanks,
Phil
