 Hi,
   I have been poking around with google looking for some ideas
 for a solution to this problem.  Can you think of an easy way to block
 all connections from a certain ip if it tries log in say 5 times and
 fails?  The idea being that it would stop someone from using a
 dictionary-based attack if they had a user-name.

 Any input would be appreciated.

Portsentry will do this. You can specify a list of ports, and what kind of 
activity to block.
