APF and BFD
My home dev server, which seems to attract a lot of internet scum had been getting hammered pretty hard by some sort of automated SSH brute-force attacks over the past few days. I had read about BFD here before and decided to give it a try.
After seeing this thing ban offenders left and right I love it. I decided to go through the code to see exactly how it works. Having used some of Ryan's other scripts before, I was pleased to see how 'dead nuts' simple and effective this thing is.
