My second administrator account works. I just logged in successfully. I'm going to keep it just in case there's something wrong with my primary administrator account which I am using right now. I've made a ton of mistakes while learning how to use GNU/Linux especially with Ubuntu in the past. I've locked myself out or I've made it impossible for me to login as any user in the past because I've gone way overboard on security.

I've learned some hard lessons as I have gotten older. I'm done with my security hardening process now.

I installed the harden packages from the Ubuntu Software Center. I know that they won't make me invincible, but they do improve the security quite a bit with little to no user intervention. I turned off telnet as an example.

What do you think about the harden packages in the USC?
