Final Test

For the final test, I will present a badly beaten Linux machine. It's got numerous problems on it, and they need to be fixed. Here are some problems you will run up against:

  • You don't know the root password. (Pay attention to how single user mode works, and how to change users passwords)
  • You don't know the MySQL root password, but need to get access to the database. You will need to use Google to research the answer to this one.
  • The settings in XFree86 are not right for the current monitor, so it is not starting up.
  • The /var partition is full.

  • symbolic links

  • aliases, including -s types in zsh.
  • variables

Don't worry. I'll help you guys out as needed.
