Using hosts file to block websites... isnt working

[sOwL]

My computer will be shared for a couple of weeks and there are certain websites that i need to block... Let's say i want to block facebook, heres what i did:

Opened up terminal, then typed 'sudo nano /etc/hosts'
Added '127.0.0.1 facebook.com' on the bottom, having them separated with TAB instead of spaces
Pressed ctrl+o and enter to save the file, then ctrl-x to quit the nano thing.
Then i typed 'dscacheutil -flushcache' for changes to immediatelly take place
Quit terminal

Am i doing something wrong here? I can still open facebook.com in Opera after those steps.... Am i missing something?

Hi,
what is the result of this command

$ host facebook.com

Tex

 

[sOwL]

facebook.com has address 69.63.184.142
facebook.com has address 69.63.176.140
facebook.com mail is handled by 10 mx.snc1.tfbnw.net.
facebook.com mail is handled by 10 mx.sf2p.tfbnw.net.

it doesnt matter if i have facebook.com added in the hosts file or not, the result remains the same

Wow, this is an old unresolved thread. Maybe someone will look here for an answer in the future, so might as well resolve it.

Facebook runs on https, so you'll have to treat it as such in the hosts file.

127.0.0.1 https://www.facebook.com

That should do the trick.

I have resolved it on my Mountain Lion machine

It finally works after long frustrating months. No I can block sites again.
Found this article:
Mac OS X Lion and Mountain Lion /etc/hosts file to block sites
hope it helps.
