Installing Transmission (remote and CLI) client on Raspberry Pi

I have found Transmission to be best client to run on Raspberry Pi. In this tutorial I will explain how to install Transmission and access it using it’s web interface over browser.

Though this tutorial is for Raspberry Pi, it should work for any computer running Debian flavour.

First run these commands to update and upgrade the packages you have installed.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install transmission-daemon

Create a directory where you will be saving the downloads. I have always connected a HDD to Pi and that’s where all my downloads go. Fix the path accordingly.

mkdir /media/my_passport/downloads

Run the following commands which grants access to the download directory and also adds current user to transmission-daeomon group:

sudo chown debian-transmission:debian-transmission /media/my_passport/downloads
sudo usermod -a -G debian-transmission <user>
sudo chmod 770 /media/my_passport/downloads

Before making any changes, make sure you are stopping the Transmission client. The config file resides at /etc/transmission-daemon/settings.json. Make changes to it as per your requirements. To make some changes:

sudo service transmission-daemon stop
sudo nano /etc/transmission-daemon/settings.json

Above should show you Nano editor, where you can edit the config file. Once done, press Ctrl + O (Control plus Oh) to save and Ctrl + X to exit Nano editor. Some of the changes I make are:

"download-dir": "/media/my_passport/downloads",
"rpc-authentication-required": true,
"rpc-bind-address": "",
"rpc-enabled": true,
"rpc-password": "password",
"rpc-port": 9091,
"rpc-url": "/transmission/",
"rpc-username": "avi",
"rpc-whitelist": ", 192.168.*.*",
"rpc-whitelist-enabled": false,

Make sure you keep a strong password and the file is valid json. Or else Transmission client won’t start. You can check the validity of json file on JSON Lint.

Transmission web client starts on port 9091 by default. Check:
