Portscanning is taken care of via the portscan2 preprocessor (Config Types 
--> Preprocessors --> Create preprocessors).  As for the cmd.exe and 
root.exe rules, check SIDs 1661, 1002, and 1256 among others.

Re: Ethereal, that's just a sniffer, so unless you actually want to look
through all your packets looking for bad stuff, I'd just stick with
customizing your Snort rulebase to fit your needs.
