Hmmm, ok. So I tried both ARGUS_FILTER="not host 10.6.6.6" and
ARGUS_FILTER="tcp dst port 80" and it doesn't work.

Neither does...

/usr/local/sbin/argus -c -d -n /var/run/argus.pid -I 1 -m -P 561 \
        -i em0 -i em1 -w /var/log/argus.new.out "not tcp port 80"

The following is what argus yields..

BTW - I'm watching an OC3c with about 100Mbps sustained -- looking
at two intel fiber cards. If I can provide any debugging
information please let me know.

p.s. You mentioned you're running 2.0.6; where can I grab a newer release 
     of argus to test this with? I didn't know that 2.0.6x was out.
