What can be done to keep the logs neat (i.e., free from the ssh-bruteforce garbage) is this: for a given number of login failures (e.g., 8), add an ipfw rule that blocks all traffic from the offending IP#. Of course, this has got to be automatized (script?). I used to add the rules manually, as an experiment, and I found that attacks from one IP# do repeat, though very seldom (the period may be as long as a few months). The rule list will grows without bounds :( I figure, this reduces the amount of recieved spam slightly too. Yes, not a novel idea (to phrase it soflty); yet, I actually tested it, found that there's net gain from doing that (as small as it may be), and no noticeable bad consequences.
