### Introduction
The idea is to provide the following features, chosen at install:
* a web interface for file management with [filebrowser](https://github.com/filebrowser/filebrowser)
* a DLNA server with MiniDLNA
* a BitTorrent client with Transmission, which comes with a server web interface
* an VPN client with OpenVPN
* a FTP server with vsftpd
* a web interface for file management with [File Browser](https://github.com/filebrowser/filebrowser);
* a DLNA server with MiniDLNA;
* a BitTorrent client with Transmission, which comes with a server web interface;
* an VPN client with OpenVPN;
* a FTP server with vsftpd.
In addition, Nginx is used to provide HTTPS proxy to File Browser and Transmission
### Requirements
The following list of packages must be installed manually (depending on which features are needed):
```transmission-daemon minidlna openvpn nginx```
File Browser must be installed manually at `/usr/local/bin/filebrowser`.
A "NAS user" should be defined, owner of the NAS root directory: This user shall run some of above services.
### Files
* `transmission-daemon.service` is a replacement for default Transmission service file, with more settings.
* `transmission-vpn.sh` is a script which checks if a VPN connection is active and stops Transmission otherwise.
* `transmission-vpn.service` is a service unit for above script.
* `transmission-vpn.timer` is a timer which runs regularly above script.
* `variables.conf.template` contains examples variables definitions, and should be copied locally to `variables.conf`
(with any required modifications).
* `systemd-templates/` contains Systemd units templates for all the services.
* `nginx-blocks/` contains Nginx configuration blocks.
##### Installation
* `install.sh` script copies Systemd units to their destination, with correct values.
