Hi,

If I am not mistaken I think you are looking for ids.
Your best bet would be something like snort ( snort.org ),
as it recognizes multitude of attacks and probes.
Logging incoming web server connections can be done
via server log files, thats what they are for.

Hope this helps.

Subject: monitor ALL connections to ALL ports
I currently have a DSL line and a FreeBSD firewall/gateway (dual homed).  It
has one internal IP address and 5 external IP address (one "real" ip and 4
alaises on same external nic).
What I want to do is montior and record (to log) all incoming/outging
connection (just source ip/dest ip/port).  If someone connects to my web
server it should log what ip accessed it, the time, which ip (web server
runs on 2 external ip address) and the port.  Also if someone does a port
scan against the box I should be able to tell it is a port scan (since one
ip address would be opening up a bunch of ports).
Right now I don't care what data is being sent/received, just what
connections are being made (and the details about those connections).
Any suggestions?
Regards,
Jack
