[Snort-users] how to use port_scan with snort3.0

Did you check the Snort++ user manual?  There is a section on 
port_scan.  It is similar to but updated from Snort 2.  You can use the 
default configurations like this:

     port_scan = default_med_port_scan

(taken from the example snort.lua) or you can copy and tweak any of the 
configs from snort_defaults.lua.  With Snort 3 port_scan is completely 
configurable so it is just a matter of tweaking the thresholds to meet 
your needs.

Hope that helps.
