Blocking Websites with /etc/hosts

networking dns internet hosts

Solution 1

Rather then make this block using /etc/hosts I'd suggest using a browser addon/plugin such as this one named: BlockSite for Firefox or StayFocusd for Chrome.

BlockSite

ss #1

StayFocusd

ss #2

But I want to really use /etc/hosts file

If you must do it this way you can try adding your entries like this instead:

0.0.0.0   www.example.com
0.0.0.0   example.com
::0       www.example.com
::0       example.com

You should never add entries to this file other than hostnames. So don't put any entries in there that include prefixes such as http:// etc.

Solution 2

You need to flush your DNS cache. According to this article, you can do that by restarting the following services:

nscd
dnsmasq
named

  BTW, there's no need to write M_PI / 2.0, there's already a M_PI_2 constant defined (and M_PI_4, for what it's worth).

The OP does expressly ask for solutions that don't involve browser plugins/extensions...

The last part of your answer was correct --- my mistake was that I had written http://www.example.com instead of www.example.com. Now the site is blocked.

This is useful, and both chrome & firefox has an extension named block site, both great.

Alas, what I needed was a plug-in that would ignore all the links to other sites than the current one and would be activated to sites of my own choice.

The article is from 2008 and appears to be out of date. My linux mint install doesn't have nscd or rndc.

A modification to the hosts file should take effect without having to restart anything. In case of redirects, you may have to block the target of the redirect too, though.
