CDMClient

CDM - Centralized Download Manager Client CDMClient is the client application for the CDM Server.

This client communicates with the CDM Server to periodically send the download status from Transmission/QBittorrent and check for new torrent files to download. If new torrents are available, they are downloaded and added to Transmission/QBittorrent client.

Installation

Install or Upgrade the Package

Run the following command to install or upgrade CDMClient:

python3 -m pip install --upgrade CDMClient --user

Create a Systemd Service

To set up CDMClient as a systemd service, execute the following commands:

1. Create the service file:

   echo "[Unit]
   Description=cdm-client service
   After=multi-user.target
   Conflicts=getty@tty1.service
   
   [Service]
   User=${USER}
   Type=simple
   Environment=LC_ALL=C.UTF-8
   Environment=LANG=C.UTF-8
   ExecStart=${HOME}/.local/bin/cdm-client
   Restart=on-failure
   RestartSec=3
   
   [Install]
   WantedBy=multi-user.target" | sudo tee /etc/systemd/system/cdm-client.service
   

2. Reload systemd and enable the service:

   sudo systemctl daemon-reload
   sudo systemctl enable cdm-client.service
   sudo systemctl start cdm-client.service
   

Add automatic update (optional)

To keep CDMClient updated automatically, you can add a cron job. Run:

crontab -e

Then add the following line to the crontab file:

0 3 * * * /usr/bin/python3 -m pip install --upgrade CDMClient --user && systemctl restart cdm-client.service

Configuration

The configuration file is located at: ~/.config/cdm_client/config.ini

This file is automatically generated when the service starts. Below is an example configuration:

[connection]
server_host = "https://cdmserver.com"
api_key = "1409d6ed79280aadcbe20f8f21981e89"
client_host =
client_port =
client_username =
client_password =
client_type= transmission # possible values: transmission or qbitorrent

Configuration Details:

• server_host: The full URL of the CDM Server (e.g., https://cdmserver.com).
• api_key: The API key generated when adding a new device on the CDM Server's devices page. Refer to the Devices Page Documentation.
• client_username and client_password: Required authentication for the selected torrent client.
• client_type: Specify either transmission or qbitorrent, depending on the torrent client you are using.
• client_host and client_port: Optional. If not specified, defaults to localhost and the default port for the selected client type.

Viewing Logs

To monitor the service logs, use the following command:

journalctl -fu cdm-client

Torrent Migration

You can migrate torrents between Transmission and qBittorrent with:

cdm-migrate --source-type transmission --target-type qbittorrent \
  --source-host 127.0.0.1 --source-port 9091 --source-username user --source-password pass \
  --target-host 127.0.0.1 --target-port 8080 --target-username admin --target-password adminadmin

Recommended first run (dry-run)

cdm-migrate --source-type transmission --target-type qbittorrent --dry-run

Reverse direction (qBittorrent -> Transmission)

cdm-migrate --source-type qbittorrent --target-type transmission
