Single user mode is considered as recovery mode in Linux, but many misuse it to change the root passwords .
U can password protect,i.e when a user logins in Single-user mode, the system asks for a root password
Jusy add this line in "/etc/inittab"
su:S:wait:/sbin/sulogin
Enjoy safety....

11 things you did not and will not learn in school
Bill Gates speech at a High School about 11 things they did not and will not learn in school. He talks about how feel-good, politically correct teachings created a generation of kids with no concept of reality and how this concept set them up for failure in the real world.
Rule 1 : Life is not fair - get used to it!
Rule 2: The world won't care about your self-esteem. The world will expect you to accomplish something BEFORE you feel good about yourself.
Rule 3: You will NOT make $60,000 a year right out of high school. You won't be a vice-president with a car phone until you earn both.
Rule 4: If you think your teacher is tough, wait till you get a boss.
Rule 5: Flipping burgers is not beneath your dignity. Your Grandparents had a different word for burger flipping: they called it opportunity.
Rule 6: If you mess up, it's not your parents' fault, so don't whine about your mistakes, learn from them.
Rule 7: Before you were born, your parents weren't as boring as they are now. They got that way from paying your bills, cleaning your clothes and listening to you talk about how cool you thought you were. So before you save the rain forest from the parasites of your parent's generation, try delousing the closet in your own room.
Rule 8: Your school may have done away with winners and losers, but life HAS NOT. In some schools, they have abolished failing grades and they'll give you as MANY TIMES as you want to get the right answer. This doesn't bear the slightest resemblance to ANYTHING in real life.
Rule 9: Life is not divided into semesters. You don't get summers off and very few employers are interested in helping you FIND YOURSELF. Do that on your own time.
Rule 10: Television is NOT real life. In real life people actually have to leave the coffee shop and go to jobs.
Rule 11: Be nice to nerds. Chances are you'll end up working for one.

Puzzle:: "Love in Chor-Bazar"
Question: Veru and Basanti have fallen in love (via the internet) and Veru wishes to mail her a ring. Unfortunately,they live in Chor-bazar where anything sent through the mail will be stolen unless it is enclosed in a padlocked box. Veru and Basanti each have plenty of padlocks, but none to which the other has a key. How can Veru get the ring safely into Basanti’s hands?

Ans: Veru sends Basanti a box with the ring in it and one of his padlocks on it. Upon receipt Basanti affixes her own padlock to box and mails it back with both padlocks on it. When Veru gets it he removes his padlock and sends the box back to Basanti;
This solution is not just play; the idea is fundamental in Diffie-Hellman key exchange, an historic breakthrough in cryptography.
