A lobber storage node is essentially a standard BitTorrent client with a very thin layer used to receive notification about new and modified torrents. A lobber storage node is provided as a twisted plugin and is installed from the python package index. Currently the twisted plugin works with transmission - a popular, cross-platform BitTorrent client. Other BT clients may be supported in the future.


The examples below assume a debian/ubuntu environment. If you're running another unix-like or windows OS your milage may vary. Our goal is for lobber to run on a multitude of environments and operating systems. Please provide us with patches!

Install Transmission

We recommend installing transmission 2.03 or later. If you are using Ubuntu 10.04 you may have to install transmission from a PPA:

# apt-get install python-software-properties
# add-apt-repository ppa:transmissionbt/ppa
# apt-get update
# apt-get install transmission-cli transmission-daemon

At this point you should have a transmission daemon running after each reboot. Use the /etc/init.d/transmission-daemon tool to stop/start the service in the normal way.

Install lobber-storagenode

Install dependencies:

apt-get install python-pip python-setuptools python-twisted
pip install stompservice transmissionrpc feedparser

Get the storage node from

git clone

Install the storagenode:

cd lobber-storagenode
python install

At this point twistd should have a new plugin registered. Verify this by running twistd --help and look for lobberstoragenode in the list of commands. If you see this then you're installation should be ok.

Stand-alone storage node

Here will the stand-alone setup be documented.

Storage node for Lobber web application

To start a storage node to complement the Lobber web application you need first to create a key with the right entitlements and url filter via the web ui.

To make the storage node able to write in transmissions standard download directory you need to add the group debian-transmission to the www-data user.

usermod -G debian-transmission www-data

To make transmission read files in the dropbox directory change ownership for it to debian-transmission and set the gid bit for the directory.

chown debian-transmission:debian-transmission /path/to/lobber/dropbox
chmod g+s /path/to/lobber/dropbox

Find the script lobberstoragenode in the directory scripts in lobber-storagenode.

You need to change the following options:



Copy the script to the start up script folder and change permissions on it.

cp lobberstoragenode /etc/init.d/lobberstoragenode
chmod 755 /etc/init.d/lobberstoragenode

Start the storage node:

/etc/init.d/lobberstoragenode webapp start

Unrevised old documentation

When running a storage-node for development purposes you will typically run it with both the --stompUrl and --lobberUrl parameters pointing to endpoints on your local development sandbox. When running a storage-node off of you will typically want to start it this way:

# twistd -n lobberstoragenode -k <appkey> -h -d /var/torrents [<destination|rss>]*

The final arguments is a set of STOMP destinations and/or RSS feeds. Each RSS feed is pulled regularly and each link is downloaded. If the downloaded data is a BitTorrent file it is stored in the --torrentDir directory (/var/torrents in the example above). Optionally if a --script option was given it will be run as a command with the path to the torrent-file as an argument.

If you want to notify transmission of new torrents you might do something like this

# twistd -n lobberstoragenode ... --script="transmission-remote -n transmission:transmission -a"

A more complete example. This would regularly pull all torrents linked from and ask transmission to add the new ones.

# twistd -n lobberstoragenode -k <key> -h -d /tmp \\
         --script="transmission-remote -n transmission:transmission -a" \\ /torrent/tag/foo

Useful stuff to listen to for a storagenode

STOMP destinations


What it gets you


Each newly created torrent


Each time a torrent is tagged


Each time a torrent is tagged with 'foo'


Each time the 'foo' tag is removed from a torrrent



What it gets you

All torrents readable by the current user (or key)

All torrents tagged with 'foo'
