Good evening,

Following a tutorial, I installed rails on my Ubuntu and created a new  
project using the “rails” command. After starting the built-in server,  
if I go to [http://localhost:3000](http://localhost:3000), I get the Rails welcome screen.  
But after creating a controller with “./script/generate controller hello  
index”, when I go to [http://localhost:3000/hello](http://localhost:3000/hello), the following appears  
in the console:

- → /hello

127.0.0.1 - - [11/Nov/2007:23:15:38 BRST] “GET /hello HTTP/1.1” 404 275

I tried reinstalling Ruby and Rails, but it didn’t work.

Can someone give me a light?

Thanks.
