RTorrent with xmlrpc-c support on LSPro
rTorrent is a console-based BitTorrent client with a focus on efficiency. This guide describes how to set up rTorrent with XMLRPC support.
This was performed on a Linkstation Pro with Debian installed
Thanks to MoonMaker on the buffalo nas forums. Rtorrent with xmlrpc-c from source
This forum post contains lots of additional information on setting up rtorrent and ntorrent.
Thanks Jose Luis Rivas for maintaining rtorrent 0.8.4 in debian experimental. 
Follow the guide on Installing packages from the Debian unstable branch but just replace the word unstable with experimental.
It's easy really, in my sources.list I have the line
deb http://ftp.uk.debian.org/debian/ experimental main contrib non-free
which seems to work
After gaining access to experimental packages, as root, all you need to do is
$ aptitude install -t experimental rtorrent
and it should work
I won't bother repeating the information in the good guide
Set Up rTorrent on LSPro for setting all the usual settings and using screen with rtorrent.
The following needs to be added to .rtorrent.rc to setup XMLRPC-C support
scgi_port = :5000 #scgi_local = /home/torrent/rpc.socket
See the rTorrent user guide to learn how to work with the rTorrent interface.
