Ok... So the ARE scanning. My problem or what I blame on them was still
wrong according to what you say. What really led me to that conclusion was
that I went a whole weekend with totally smooth runnings then on Monday
all the sudden I couldn't ftp over 500K without losing all @home,
including on my iMac. So it seemed that maybe their scanner was in alpha
and they weren't ready to run it 24-7 so they ran it on business days
while the big guys were in the office. But regardless if my theory was
correct they would have to catch me with in a few minutes each time. 

You know it's funny that I'm even using the word "catch". I'm trying to
download Enhydra and Oracle for pro use but I'm not allowing anyone use of
my services.

So for a newbie is port sentry gonna be a weekend project or is it pretty
simple. I was just blown away at how relatively easy Kernel compiles are.
Impressed with how far I've come in 10 months (so something's bound to go
wrong real soon) :}

Where can I find it?

I've checked all my logs and haven't found any noticable activity. Is
there any special set-up you recommend (for picking up activity).
Because.... even though I think the recompile stopped the @home
problems... I did strengthen my firewall thanks to one really helpful
member of this list. But I didn't actually restart at the time. And only
did so once I re-compiled. Maybe the firewall changes didn't actually kick
in, because of my own ignorance, until I rebooted. And my ftp problems
were coming from a hack. I still can't upload more than 10kbps from my
