I have set up a Turnkey LAMP instance on a VM and it is working fine.  But, the only file I can see is the index.php file when I use the ip address.  When I try to load any of my other files using the browser, I get a message that the files cannot be found. 

I am on a linux machine running Ubuntu 13.4 and I am using Firefox as my browser. 

Any help/advice is welcome.  Thanks.
