in default configuration snort will detect about 97-99% false positives
as far as "intrusion" goes. at my last employer, without configuration
on 2 T1s with ~5% utilization on each I got upwards of 40,000 events per
hour. It took about 75 hours of log analysis and tuning to get that
number down to a more managable level of ~20 events/hour.

so in most cases your fine. all of the attacks you list look pretty
harmless to me.

I reccomend DEMARC PureSecure as a front end to snort(www.demarc.com).
It is not free for commercial use, but is for personal use. It's a real
powerful console for snort I've been using it for over a year and a half,
there are screenshots of it on demarc.com. It also acts as a system file
integrity checker as well as a network service monitor. Real nice program.
I run it on FreeBSD mainly.
