I think I have written before about DenyHosts, but this evening, it prevented somewhere around twenty thousand individual hosts trying to login to one of my servers. The hackers have gotten smarter - that they used to just try from one host, which was trivially blockable, even manually. But, thanks to denyhosts (and the fairly easily trackable behavior by the hackers), they think they get a couple chances to guess a password before being blocked. Note, that I say "think", because they actually don't get any, due to the way they are doing it.

No, you aren't reading the Internet Wayback Machine - this is 2008, and the National Institute of Mental Health still uses DOS for testing subjects.  (If it isn't broken, don't fix it...  And they can be much closer to real-time accuracy with DOS rather than Windows.)  However, as the data sets get larger, and floppy drives become increasingly less common, it is harder and harder to get the data off of their testing machines back to the experimenters' desktops to analyze the data.
