Torrent Client/Server

Headless Torrent Server/Client: Built on a Raspberry Pi

In this tutorial I will show you how to build a headless torrent server and client. I will be using the very popular Transmission as my torrent server and client. The first step is to install the necessary software:

sudo apt-get install transmission-daemon

After installing Transmission we need to stop the service and edit a few settings. Here is a list of some of the important settings. I have also annotated a copy of my settings.json file below.

  • “download-dir” – This is the folder where you want to save your completed downloads (/mnt/torrents/complete)
  • “incomplete-dir” – This is the folder where your partial downlaods are saved until complete (/mnt/torrents/incomplete).
  • “incomplete-dir-enabled” – Set to 'true' to enable the above 'incomplete' folder
  • “rpc-whitelist” – Include the IP ranges you want to access the transmission web interface
  • “rpc-whitelist-enabled” – Set this to 'true' to enforce the above whitelist.
sudo service transmission-daemon stop
sudo nano /etc/transmission-daemon/settings.json

All that is left to do is start the transmission-daemon and test the transmission web interface

$ sudo service transmission-daemon start

To go to the transmission web interface just go to your web browser input your url: http://serverip:9091 It should look something like this:
