Capture Filter Not Working

[Eric]

Greetings,

I've been running 2.0.5 with this [1] config on both FreeBSD and
OpenBSD. It appears as though neither of the following works.

ARGUS_FILTER="not tcp port 80"

or 

ARGUS_OUTPUT_FILE=/var/log/argus/argus.out "not tcp port 80"

All I'm trying to do is limit my captures to anything *but*
80/tcp.

Did I miss something? :) 

Thanks.
