The login attempts don't really cause any harm once they are being 
ignored, but you can use:
     G_HACKER* settings
which you may wish to play with.  It may still result in log entries 
with each attempt, but it can be effective in decreasing the number of 
guesses that are achieved and thus reduce the chances of a successful 
breakin.
