LXC Containers and rTorrent

Install LXC stuff on the host machine.

apt install lxc 

Configure a network bridge, this will not be NATed so it will appear on the network as a host device:

auto br0
iface br0 inet dhcp
    	bridge_ports eth0
        bridge_fd 0
        bridge_maxwait 0

Append the network config to the defaults /etc/lxc/default.conf: = veth = up = br0

If you want to store the containers in a non-default location. Set the path in /etc/lxc/lxc.conf

lxc.lxcpath = /data1/LXC/

Create the container:

lxc-create -t download -n torrent

Get tun for the VPN and mount some of the host’s directories. Append this to /data1/LXC/torrent/config or the default location.

lxc.mount.entry = /data1/Torrents Torrents none rw,bind 0 0
lxc.cgroup.devices.allow = c 10:200 rwm

Start the container and attach to the console:

lxc-start -n torrent
lxc-attach -n torrent

From inside the container install some things we need:

apt install openvpn rtorrent screen openssh-server vim ufw 

Create the tun mapping:

mkdir /dev/net
mknod /dev/net/tun c 10 200
chmod 0666 /dev/net/tun

Set up ssh access, new user with sudo, ufw etc.etc.

In .rtorrent.rc add:

scgi_port =

And in nginx either container or localhost add scgi proxy for things like transdroid.

    location /RPC2 {
            include     scgi_params;
            scgi_param  SCRIPT_NAME  /RPC2;

Now you have a container which downloads from a VPN and exposes its XML RPC to the network.
