Enable it with
services.transmission.enable = true;
and optionally configure it
services.transmission.settings =
{
download-dir = "/srv/torrents/";
incomplete-dir = "/srv/torrents/.incomplete/";
incomplete-dir-enabled = true;
rpc-whitelist = "127.0.0.1,192.168.*.*";
# for users in group "transmission" to have access to torrents
umask = 2;
};
The above settings are written/merged into settings.json each time the
service is about to start.
