About

DroboPorts.com hosts HOW-TOs and ready-to-install versions of apps ported to the Drobo FS and Drobo5N from DRI.

In other words, I just really like my FS and 5N, and I want to make the most out of both. If you are a Drobo FS/5N owner, then please, have a look around and find out how to get more out of that cool looking black box.

For more DroboApps, check the official DRI DroboApp repository.

For more unofficial DroboApps and other DroboFS tips, check jhah's Drobo site.

rtorrent-0.8.8

Warning: This version of rTorrent is deprecated and has been replaced by rTorrent 0.8.9. This page and attached files are being kept for reference, but should not be deployed on any systems.

Overview

This tutorial creates both the rTorrent client and the web interface ruTorrent. This version of rTorrent uses a different approach than the previous version, since it prepares all the components separately, but still in a way that just works if they are all deployed correctly.

rTorrent requires zlib, openssl, ncurses, libsigc++, xmlrpc-c, cURL, and libtorrent to compile. We compile all the dependencies on a different destination folder, and then statically link them into rTorrent to make deployment easier.

Instead of packing all the additional apps that ruTorrent requires in this package, this version requires the DroboApps to be installed separately. The dependencies are:

  • lighttpd: mandatory. The version of Apache provided by DRI does not have a working implementation of the PHP plugin
  • php: mandatory. Lighttpd and PHP are not bundled together
  • screen: mandatory. Screen is used to run rTorrent as a service
  • curl: mandatory. cURL is used by ruTorrent to communicate with rTorrent
  • procps: optional. Pgrep is used by the create plugin
  • mediainfo: optional. Mediainfo is used by the mediainfo plugin
  • unrar: optional. Unrar is used by the unpack plugin

If you do not need those plugins, you can disable them from the ruTorrent UI. Otherwise, make sure these DroboApps are installed before you install ruTorrent.

Otherwise, keep in mind that this is a very large DroboApp, with lots of dependencies. I have repeated this procedure from scratch several times to make sure it really works, but please keep in mind that this is a very complex DroboApp, and therefore proceed with caution.

Preparation

Make sure you have a cross-compiling virtual machine properly setup. You'll also need the updated version of the GCC cross-compile toolchain since rTorrent uses GCC Atomic Builtins.

Compilation

The compilation has a small two-pass step due to the fact that XMLRPC-C is not very cross-compile friendly. As usual, we do a first pass to get the native binaries, then a second pass for the cross-compiled binaries.

$STRIP $DEST/bin/rtorrent

Packaging

First we package rTorrent:

cd $DEST
mkdir -p var/run var/log var/session
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/rtorrent.rc.default -O etc/rtorrent.rc.default
~/bin/package.sh

Then we package ruTorrent:

sudo apt-get install subversion

cd ~/code/
svn checkout http://rutorrent.googlecode.com/svn/trunk/ rutorrent
cd rutorrent
find . -name ".svn" | xargs rm -fr
mv rutorrent www
mv plugins www/

wget http://www.droboports.com/app-repository/rtorrent-0-8-8/admin.url
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/service.sh
chmod a+x service.sh

mkdir -p etc var/run var/log 
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/rutorrent.conf -O etc/rutorrent.conf
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/rtorrent.conf -O etc/rtorrent.conf

pushd www/conf
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/config.php -O config.php
popd
pushd www/plugins/create
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/create-conf.php -O conf.php
popd
pushd www/plugins/mediainfo
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/mediainfo-conf.php -O conf.php
popd
pushd www/plugins/unpack
wget http://www.droboports.com/app-repository/rtorrent-0-8-8/unpack-conf.php -O conf.php
popd
pushd www/plugins
rm -fr httprpc rpc
popd

~/bin/package.sh

Installing

DroboAdmin link: Install rtorrent-0.8.8 first (this link only works if you have not changed the DroboFS name) and then install rutorrent-svn1696. Otherwise, download below and place it in you DroboApps share.

Final remarks

Again, make sure all the dependencies are installed before running ruTorrent. This DroboApp will automatically detect the presence of all the dependencies if they are installed at their default location, and should require no additional configuration to run.

rTorrent is configured to run as root, and ruTorrent is not password protected. This may be addressed in a future release, but right now rTorrent crashes without explanation if run under a non-root account. If you want to protect ruTorrent, edit etc/rutorrent.conf and add the authentication configuration following the model from droboadmin.conf.
