I guess something is wrong with me and the way I thought I should use bpf
ifliters (snort 1.86, 1.87beta and 1.87 release)

If I use a bpf filter I don't get ANY alerts.

Starting snort like this:

/usr/local/bin/snort -doDI -m 022 -z \
-c /usr/local/etc/snort.conf -i rl0 -l /var/log/snort \
-F /usr/local/share/snort/snort.bpf

cat /usr/local/share/snort/snort.bpf:
not src host

someone answered, and I guess it wasn't clear, I thought they said that it
was a bug and was being addressed.

What I want is to filter out all events, alerts (at the bpf level) emenating
from host

(no, pass ip any -> any any is not what I want... Im looking to
eliminate stream, fran ang syn alerts as well).
