Ok I changed the conf to only send the log data to mysql – I am trying to
stick to the config that silicondefense.com puts out on
After re-reading that doc I also made a couple of other changes but so far
no luck on detecting all the nmap stuff that I am sending. I am now able
to see portscans going to the IP address of the snort device but still
nothing comes up when I sweep on the other IPs that I need to monitor.
When I run snort –v –i2 I see all the traffic going through that system
(there is a lot of traffic so I can’t simply see the portscan taking
place). When I use windump and I narrow down the scope of it to only
packets w/ a source of the machine that I am using to run nmap I am able
to see those packets then so I know that the stuff is in fact getting to
the snort device.
I took a look @ the mysql and there is data there from the portscan that I
sent to the ip address of the snort so at least the logging part is
talking place in one way shape or form.

For what is worth I have 2 nics on this system one to access the ACID
console that only has TCP/IP bound & its firewalled (MS) and the second to
run the monitor and that one has no bindings whatsoever.
Any ideas at to where I screwed up this config a really welcomed.
