Hmm, well that's where I get confused. I have stream4 and stream4_reassemble
enabled, but *don't* run snort with the "-z" option. I have some alerts
that need to trigger off "flag:S" - which I think stops working when I
enable "-z".

Basically I have some alerts that I want to trigger when DMZ hosts attempt
to make outgoing connections. I don't care if they succeed or not - the mere
presence of a SYN packet is enough reason to alert.

How can I use "-z" and still do that?

Thanks for any help
