The situation is: I don‘t want to able to surf certain websites out of distraction of boredom, while I am in the University, studying. My idea is:

  1. Create a sudo-password which is to complex to memorize it, write in somewhere and leave it at home when I go to the University.
  2. Create a user-account with restrictions, on the websites, which can be visited.
  3. Study without distraction.

It's very unlikely that you can add any restrictions on other user accounts without being a super-user yourself. It's certainly not possible in Ubuntu's default and most other sane privilege management configurations.

  • I am sorry for not expressing myself precisely: I am the super-user but not on that account. The situation is: I don't want to be able to surf certain wegsites without the sudo-password. (Which i will make too complex to remember and leave it on a piece of paper at home when I go to university.) – slobad Sep 10 '16 at 18:00

    So by "securely" you actually meant: too difficult/inconvenient to do out of distraction or boredom. That changes the problem a lot. Please amend your question to clarify that. – David Foerster Sep 10 '16 at 19:32
