Editing hosts file to block sites not working

windows-7 hosts-file

Solution 1:

I'm not sure if this will solve your problem, but some suggestions:

  • Remove any extensions you might have on your file.

  • Make sure you have this line somewhere in your file (preferably at top)

    127.0.0.1 localhost

Edit: Should be localhost not localhosts (no 's' at the end)

Edit 2: Here's a pretty complete list of hostfile related info on serverfault. Maybe it'll help: https://serverfault.com/questions/452268/hosts-file-ignored-how-to-troubleshoot

Solution 2:

To block sites you need to list all the domain-names, for sites like facebook and youtube that's a really big list of names and ip-addresses. I'll copy the code that I used for blocking youtube beneath.
