Blocking websites with /etc/hosts
You can use
/etc/hosts to set up local domains but you can also block access to websites using the same syntax.
You only need to redirect the website domain to your own computer (
127.0.0.1). For example, to block facebook.com, edit
/etc/hosts/ file (with root permissions) and add the following line:
# /etc/hosts 127.0.0.1 facebook.com
Save the file and check you cannot access
curl or a web browser.
$ curl -I facebook.com curl: (7) Failed to connect to facebook.com port 80 after 0 ms: Connection refused
This rule blocks
https) but doesn’t block
www.facebook.com unless you add another rule.
# /etc/hosts 127.0.0.1 facebook.com 127.0.0.1 www.facebook.com
You can add as many rules as you want.
