I'm not very used with servers but for a little non-profit association, I need to install a server for LibreOffice documents sharing locally and through the internet. Locally, we have 3 pc with Xubuntu. Through the internet, that can be pc windows, linux or Mac. All the users will use the same directories where documents will be stocked.
For the moment, I have installed Ubuntu server 13.04 and Webmin 1.650. What do I have to configure now ? What servers do I have to configure now ?
Thanks for your help.
