port scans

[Sidharth Deshpande <sade_in () yahoo com>]

Hello team,
 
I am running snort on a test network. I was interested to know if snort can detect port scans that are extremely slow. 
Port scans that span over a few days for example.
 
Is there a way for snort to identify this kind of scan?
 
I hope you could help me out with this information.
 
Thanks
