Use of Host Attribute table, Frag3, and Stream 5 question

If I'm using a host attribute table that I generated with nmap and
Hogger, but my snort.conf only has these two lines:

 

preprocessor frag3_global: max_frags 65536

preprocessor frag3_engine: policy first detect_anomalies timeout 180

 

What will it do when it gets to a host in the attribute table that is a
linux machine or a Cisco IOS? Will the attribute file basically only be
good for the OS's that are the "first" category? Meaning that I'm really
only using the attribute table to look at the hosts that are running
Windows, MacOS, or HP-UX? 

 

I know I can specify more "policies" in the snort.conf but, I have to
bind IP's to that policy. Which can be time consuming when machines are
constantly being added and removed. 

 

 

Thanks,

Andy Berryman
