Transmission

From NixOS Wiki

Installation

Install by adding transmission_4-qt or transmission_4-gtk to your packages list

environment.systemPackages = with pkgs; [ transmission_4-qt ];
environment.systemPackages = with pkgs; [ transmission_4-gtk ];

If you want to configure the settings declaratively with within configuration.nix, you will have to instead install transmission-qt or transmission-gtk. Do note that this is using version 3.0.0 instead of version 4.

environment.systemPackages = with pkgs; [ transmission-qt ];
environment.systemPackages = with pkgs; [ transmission-gtk ];

Service configuration

You can declaratively change the settings via Nix by modifying services.transmission.settings. View the documentation for more info. Like the previous section has said before, you'll have to use the nixpkgs transmission-gtk or transmission-qt for this to work.

Example:

services.transmission.settings = {
  download-dir = "${config.services.transmission.home}/Downloads";
};

Password-protected RPC

The default method of editing the configuration and restarting the daemon will not work because of the way the configuration is handled. It is however possible to once set it in clear in the settings, and then copy the generated hash to the setting, removing the in-clear copy from the configuration.

Example: allow remote access

To control the daemon remotely, put the following lines in your /etc/nixos/configuration.nix:

services.transmission = { 
    enable = true; #Enable transmission daemon
    openRPCPort = true; #Open firewall for RPC
    settings = { #Override default settings
      rpc-bind-address = "0.0.0.0"; #Bind to own IP
      rpc-whitelist = "127.0.0.1,10.0.0.1"; #Whitelist your remote machine (10.0.0.1 in this example)
    };
  };
