File Server seems to work.
WHM backups have been configured and are FTPing backups daily/weekly/monthly to the server.
Will want to test out the backups on the AlienVPS server at some point to practice recovery.
The rest of the file-server still needs configuring. There are WAY too many options (especially for Samba) so if I will make this into a public release I will certainly have to make some new modules for webmin. Simeple File server module.
I also want to move the whole LAN to a LDAP setup so that all users get their passwords from the server. I will let the File-Server do the LDAP serving.
