Remote rTorrent setup

nginx.conf for SSL and basic authentication:

server {
    listen 443 ssl;
    server_name rtorrent.local;
    ssl_certificate /.../rtorrent.crt;
    ssl_certificate_key /.../rtorrent.key;
    location /RPC2 {
        scgi_pass 127.0.0.1:5000;
        include scgi_params;
        auth_basic "private";
        auth_basic_user_file /.../rtorrent.htpasswd;
    }
}

.rtorrent.rc:

scgi_port = localhost:5000

There is a lot of work to be done

You can run lighttpd on port 8080 as a regular user in the repo directory using:

$ lighttpd -D -f lighttpd.conf

$ xmlrpc localhost:8080/RPC2 system.listMethods
