Fun in .rtorrent.rc

scgi_local = /home/user/.rtorrent.socketNeeded for web interface... more on that later.

session = /home/user/.rtorrent.sessionKeeps rtorrent from having to rehash after restart (attn: Ryan)

schedule = ratio,60,60,"stop_on_ratio=200,50M,300"Stops torrent when 2.0 ratio reached. 3.0 if less than 50M

schedule = watch_directory,10,10,load_start=~/watch/*.torrent

schedule = tied_directory,10,10,start_tied=schedule = untied_directory,10,10,close_untied=Start torrent when placed in watch directory, close when removed

Other Goodies

Run command when torrents completedMove torrents aroundSend emailrm -rf ~/torrents/

Schedule upload/download rates

Set upload/download rates for IP or IP range (useful for Resnet)

Scripting limited mainly by your shallow imagination.

RSS feeds need to be handled by an outside app.

But I Paid Money For My Mouse!

rTorrent can interact with SCGICompatible with both Apache and LighttpdMany interfaces available...

Getting a GUI

As mentioned earlier: scgi_local = /home/user/.rtorrent.socketAlso works: scgi_port = 127.0.0.1:5001 In Lighttpd: server.modules += ( "mod_scgi" ) scgi.server = ( "/RPC2" => ( "127.0.0.1" => ( "host" => "127.0.0.1", "port" => 5001, "check-local" => "disable" ) ) )
