This depends on what you are protecting, if the case is of non-crucial 
information, I wouln't advise pursuing the matter too much.
You should however chase the alleged individual/s's butt in the 
following cases:
The host contains vital information of which knowledge by others could be 
disasterous.
The intruder has succesfully penetrated your system.
You want to have fun and hassle him <I always do!>.
In any case, making contact with the attacking host is advisable as most 
hostile activity come from taken-over accounts.
Of course, spooking the guy with a message from root @
 whitehouse .
 gov 
saying that your host is of military importance to the govt. etc. etc. 
etc. can be fun, depends on how much fooling-around time you have.
