We'll, I guess iptrap works. Here's a list of today's catches on my home PC.
Anybody you know?

While iptrap isn't super sophisticated (it only catchs straight tcp scans),
it's pretty clear there are lots of newbies out there who haven't discovered
the SYN or ACK attacks yet.  It's pretty simple to configure and works with
iptables and ipchains.  You can also have it run a script when a particular
port is hit.

Is there anything better out there (portsentry???) that can augment
iptables?
