(Moved from Ask Ubuntu because they said it'd fit more here.)
I'm completely aghast at the lack of parental controls in Ubuntu 16.04 LTS (Xenial Xerus), and how even Ubuntu.com's suggestions are so out-of-date that some are impossible now. I'm setting up a computer for my cousin, and his father doesn't even know what an OS is; he just wants to make sure his 8-year-old kid is safe on the computer.
I need something that will:
- Be very easy to use, to the point that this uncle who does not know what an OS is will be able to use it.
- Allow general computer time to be limited
- Allow internet browsing time to be limited (might also cover most of the above point)
- Allow sites to be blocked without manually maintaining a list (i.e. "Block all PG-13 or higher websites")
- Allow specific sites to be whitelisted (e.g. "*.youtube.com/*")
- NOT set up or connect to a proxy or alternative DNS, as they're with Comcast, who's historically been very keen to drop service at the slightest hint of alternative internet usage. Additionally, I don't want to be called back because something isn't working right for the whole family. The ideal solution just affects this one computer.
- Allow application access to be limited (searching, installing, and running)
Essentially, I want what Windows has, but in Ubuntu.
I can't use something like:
- Timekpr, Timoutd, or Nanny, as these are no longer available or supported
- OpenDNS as I don't know how Comcast will treat that. Even if there are now laws about data equality, I can't be sure Comcast won't find some loophole. Further, it doesn't accomplish any of the time- and application-based requirements listed above.
- Scrubit because their modem/router is rented from and thus owned by Comcast. Also the ease of use thing.
I'd like to keep the answers to 16.04 LTS until the next LTS release comes out (presumably 18.04)
