I think this is a personal or site preference whether you want to track 
by source or destination.  The logic of tracking by source is that if 
you have an attacker attempting multiple logins to one or more hosts in 
a short period of time, the alert should fire.

If you track by destination, you run the slight risk of having the alert 
go off if multiple users have failed logins within a short amount of time.

That's exactly my issue with the current version. Please note that the packet
signature is for the *reply* so the attacker is the *destination*, not source.
