Forgotten Passwords

Forgotten Passwords has got to be the most common problem around. People forget their passwords and then come to the system administrator. In Linux you can reset someones password by typing some thing like this:

bash# passwd bob
Changing password for user bob
New UNIX password: 
Retype new UNIX password: 
passwd: all authentication tokens updated successfully

This is one that you will just have to get used to. People are not the best at memorization.
