The post is old, but in case someone reads it:
Don't use eBox as a web server platform because:
Specific web server software does not come with the default installation. I can't remember exactly what was and what was not installed because I tried this a while ago.
You can install apache2, php, mysql, ftp, etc, but it's hard to configure them after that and get them to work properly. Most likely you won't be able to.
You can't see what's happening behind the scene. When I got eBox running, I created users, shares, and then wondered where's everything, what to share, where's public_html, where's phpmyadmin, why aren't php scripts running, etc. A linux expert knows these things, but I needed to see lists of files and folders in order to know where I was and what was happening.
My suggestion: If you want to use your machine for file printing/sharing, use eBox.
If you want to use it as a web server/development server for web based applications install ubuntu server, select all packages (ssh, web server, mail server, print server, etc) and then run sudo apt-get install webmin
you can access the webmin interface by typing
https://server.ip:10000You'll be ok from there.
