Censor - Scheduled Website Blocker

Dependencies: iptables, ipset, systemd, cronie, bind-utils, polkit, gtk2

Censor is designed to block sites from the black list according to the schedule: days of the week, time.

It has three blocking options that differ in their effectiveness:

• normal; sites from the list are blocked using ipset + iptables/ip6tables
• dictionary filtering method; useful for blocking "difficult" sites like youtube.com
• only web-surfing; method allows you to disable VPN, Torrent, Skype and other services

How to work

• Add to the list addresses of sites without http(s) that you want to block
• Specify the days of the week and the time interval during which the blocking will be active
• If necessary, specify the desired blocking method (the strongest - everything is included)
• Click the Apply button

Open a browser and check your work. If you changed the blocking rules again, the browser needs to be reopened and check the work again. The Reset button removes all locks and returns full access to the Internet.

In case the site is not blocked (eg yotube.com or similar), add another one of the same address with www. prefix at the beginning (www.youtube.com) and click Apply. Reopen your browser and check the blocking again.

Note: I remind you that the time in the scheduler is set in a 24-hour format. For example, if it is 4:27 PM on your computer, then you need to specify 16:27 in the scheduler. PM is the time after noon, i.e. after 12:00.

Tested in Mageia-8/9, ROSA 12.3, Fedora-36, LUbuntu-22.04.
