"Wish I could've seen his face when I told him how, armed with his IP (he was on dial up so no router) I could get into his machine without knowing his username or password, and have full control over his data. I did talk him through how to block SSH at the firewall and how to open a terminal and change a few things so it was secure."
Would you change your mind if his face took on a look of complete puzzlement instead?
