Editing hosts file not taking

I have been trying to edit my hosts file in Snow Leopard via Terminal, but i can't get the sites to take, even after i flush the cache. For each entry, i do 127.0.0.1 google.com for example. I ahve tried numbering them differently like 127.0.0.2, 127.0.0.3 and so forth for each entry as well, but that won't work either. What am i doing wrong?

 

That's exactly what i did, but it's just not working. I even downloaded that Hosts pref pane and that read what i had in there, but it wouldn't work either. I also tried adding to that Hosts pane, but unfortunately, it wouldn't save what i inputted, everything was dropped immediately after typing it in.
