<html> I was looking and at playing around with /etc/ssh/sshd_conf. What I want to do is after say 5 or so failed attempts to ssh, I want it to block ssh at least for a time (to keep people from hacking in). I uncommented anything that looked like it might do that, restarted sshd (even rebooted). Then I tried to ssh several times making up things for password: banana, orange, lemon, apple, etc. (the real password is nothing like that). I got through all the fruits and several vegetables and it still wasn't denied. When I finally entered the correct password it let me in right away. What is the correct way to block ssh attempts after several failed ones? </html>
