Synotools

A Python API wrapper and toolset for interacting with Synology NAS devices using DiskStation Manager (DSM). The repository provides two different toolsets to communicate with your NAS:

  • API: Through a Python wrapper simplifying DSM queries.
  • Command system: Through sh scripts hosted in the device, but called from any unix system capable of running fabric and python.

API requires valid credentials as described in the section below.

Getting Started

Install the package with pip:

python -m pip install synotools

Unix users (Linux, Mac) Create your credentials file in ~/.synotools/credentials:

Windows users: Use C:\Users\<YourUsername>\.synotools\credentials.txt instead.

# Device access credentials
SYNOLOGY_IP=your-ip
SYNOLOGY_PORT=your-port
SYNOLOGY_USERNAME=your-username
SYNOLOGY_PASSWORD=your-password

# Deluge service credentials
DELUGE_IP=deluge-ip
DELUGE_PORT=deluge-port
DELUGE_USERNAME=deluge-username
DELUGE_PASSWORD=deluge-password

# VPN settings
VPN_ID=vpn-config-id
VPN_NAME=vpn-config-name
VPN_PROTOCOL=vpn-protocol

A list of all fields can be found on env.sample, and this file can be used as a template for your credentials. Once populated and after completing setup you will be able to run commands:

python <installation-folder>/commands/<command-name> <args>

Read the Using the tools section for more information about available commands!

Setup

Credentials

Valid credentials are expected to be stored locally, allowing the tools to connect to the device via local network. Fill in the following credentials in your credentials file:

  1. IP: E.g. 192.168.1.35
  2. Port: 5000 for http, or 5001 for https
  3. Username: Same username you normally use to log in through the web interface
  4. Password: Corresponding password

Finding out your local IP will depend on your OS, router configuration and other factors. Please refer to DSM's User Guide for more details on how to get or set your device's IP. It is strongly recommended to set a static IP to your NAS, so that the commands and SSH access works reliably without the need to update IP.

Note: Fore security reasons remember not share your personal credentials file or password! Do not commit to repository, or share it with anybody. That file should be private and stored safely, locally.

SSH key

synotools uses fabric (built in top of paramiko) to handle SSH connections. Certain assumptions are made regarding credentials configurations and SSH keys. It is recommended to set up a SSH Key in your default SO's SSH location. This guide, although focused on GitHub, can assist. Make sure to store the private key in your default location (~/.ssh for Unix systems), and make a note of your public key contents or location, as it will be required for the next step.

Enabling NAS SSH access

By default terminal access is disabled in your device. Enable it as described in the official support.

Then, the public key needs to be added to authorized_keys in your device, and correct permissions set. This handy guide may help.

Installing Deluge in your NAS

The download command uses Deluge remotely, so it has to be installed and configured before attempting.

1- Download and install Synocomunity. 2- Deluge's auth config has to include a user, password and permission level that will be used to connect remotely. 3- Deluge server's host ip and port. Defaulted to 127.0.0.1 and 58846 respectively. 4- Once those variables are set, copy them to their relevant fields in your credentials file.

In order to set up Deluge, you can either:

a) Use Deluge's default username: deluge and password deluge, or b) Create your own user, as described here.

Note: If a user is going to be created, folders in the NAS are likely to differ compared with the guide above depending on your system. Auth file might be located in /var/packages/deluge/target/var, for instance.

VPN client configuration

The NAS can connect through a VPN network interface, which needs to be set up first. This document explains the process. Once a VPN profile has been set up and used at least once, VPN configuration may be retrieved from configuration and copied into the credentials file. These details can be obtained from vpnc_last_connect as explained here.

Using the tools

Most commands currently included in the tools are sh scripts expected to be hosted in the NAS, with either sh or python scripts that are run locally. Although most scripts can be run directly from python, a number of .docker scripts have been added so that anything can be run in one command.

NAS script installation

This step is necessary before attempting to run any other script, as they rely in the scripts having been installed first!

./install.docker <your-ssh-key-name>

# e.g. ./install.docker paulo_rsa

Gathers all scripts in synotools/scripts, zips them and deploys them to your NAS ~/.scripts folder. User is taken from the credentials file. SSH is required to connect to the NAS without additional authentication.

Note: Adding ssh key to Docker install image means that this image should never be shared publicly (i.e. pushed to Docker repo) for security reasons.

Download torrent

Add a torrent to Deluge in the NAS, downloading it to default download folder.

python synotools/command/download.py "<your-torrent>"

# e.g python synotools/commands/download.py "https://torrents.linuxmint.com/torrents/linuxmint-17-cinnamon-32bit-v2.iso.torrent"

# e.g python synotools/commands/download.py "magnet:?xt=urn:btih:336165b4134e3754fa6996d881a7e7b55a40eb68&dn=archlinux-2019.06.01-x86_64.iso&tr=udp://tracker.archlinux.org:6969&tr=http://tracker.archlinux.org:6969/announce"

Connect to VPN

Check whether NAS is connected through a VPN, and connect if it's not.

python synotools/commands/vpn_connect.py

Compatibility

Tested with Synology's DS218j model.

Development

This software has been created and is maintained in Linux Mint, but developers should be able to contribute using practically any Unix platform. Before starting, the following tools will need to be installed and configured:

  • Docker
  • Git
  • Pipenv

Dependencies

There are two types of dependencies:

  • Python Packages: Handled automatically thanks to pip and pipenv. Both the core and development dependencies are included in the project's Pipfile.
  • Other Dependencies: In order to prevent the developers' system from cluttering, all external dependencies that are not installable with package managers are supposed to sit in the dependencies folder. Scripts are provided to install these automatically.

Development environment setup

1- Clone the base repository on a location of your choice.

git clone git@github.com:DazEdword/synology-toolset.git

2- Configure your credentials file and ssh keys as explained in the Getting Started section.

3- Ensure all scripts are executable.

make permissions

Running tests

Several Docker scripts have been set up to unambiguously run a subset of tests, while taking care of all required dependencies. Using these scripts Docker should handle everything for you:

# Unit tests
make test/unit
# Scripts tests (bash unit tests)
make test/scripts
# Integration tests
make test/integration

Alternatively, a virtual environment could be created and all dependencies installed via scripts, allowing for richer test runs as covered in pytest's documentation.

Note: Integration tests may require your NAS to be on and available in your local network in order to pass, as tests could be directly interacting with it.
