I have experimented with productivity software and browser control apps, etc.
This is the most simple way to block sites you don’t want people to access on your machine including yourself. IE, Facebook, Twitter, etc.
Navigate in My Computer to C:\Windows\System32\drivers\etc and open a file called ‘hosts’.
Open up the file with notepad and you will see:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a ‘#’ symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
ALL THIS IS JUST EXAMPLE STUFF THAT IS COMMENTED OUT. DO NOT WORRY ABOUT IT.
To add a site to block just add this text below:
0.0.0.0 facebook.com
This will resolve facebook.com to a location that does not exist effectively blocking it. This is a very simple way to achieve this result.
Enjoy,
Mike
