Thanks to the great script by chrisj (http://www.mysettopbox.tv/phpBB2/viewtopic.php?t=14399) I was easily able to install and setup torrentflux on my myth box, it's working but it's SLOOOOOOW.



The box is behind a router...do I need to forward more ports or something? Why is it this slow?

Thanks,
-C

How many seeders/leechers on the torrent you posted stats for? If you fire up the same torrent on another box that has an already configured torrent client (and the proper ports forwarded, etc) what kind of speeds do you see?

About 1000 seeders, using the btdownloadcurses on the command line it runs faster, granted, it's only ~20K/s but that's faster than the ~5 I get in flux.

I don't have torrentflux installed anywhere at the moment, but earlier in the year I was running it and didn't have any trouble gettings speeds up in the 200-300k/sec range. Aside from double checking to make sure your ports are forwarded properly, I don't really know what else to suggest.

I've been doing research, it appears torrentflux runs on ports 49160-49300 (not 6881-6999)...this machine is behind my router, a dlink DI-524,

Under "Applications" I added two triggers (TCP):


This I thought would speed things up...but it doesn't seem to.

Well, torrentflux CAN push a lot of traffic when it is called for. I seeded a new version of Suse awhile ago just to see. I hit over 60Mbits/sec for an hour, and sustained >40Mbits/sec for about a day.

My Myth-related seeds have never hit those rates, tho. Best I've seen is about 10Mbits/sec for an hour here and there. More typical is 200-500Kbits/sec. for a few hours at a time.

I used to use TorrentFlux, but I found all those Python processes (And the fact it was running under Apache, used the filesystem for communication, didn't have global speed settings, and wouldn't restart torrents automatically) made it horrible to use.

Then I discovered BTG (http://btg.berlios.de). It has a VERY nice web-based frontend, supports multiple users, global bandwidth limits, DHT and encryption, and it's fast and lean, running as a single process rather than lost of individual python processes.

The prerequesites are a bit of a hassle (Needs Rasterbar libtorrent, which in turn requires libboost), but once you've got those sorted, it's very easy to set up and use.

Any chance of this being included in the next version of KnoppMyth?

Just as an aside, processes are NOT "bad". Python has some support for threading, but spawning off separate processes in Python is a good design decision. If you take a look at "ps -ef" you'll see your linux box is running quite a few processes already!

You generally DO have to poke holes in your firewall for
bittorrent, else you get very low download rates.

This might be described as "port forwarding", "virtual server",
etc in your router setup.

Find out exactly which ports your client uses and set up your
router / firewall to forward those to the box that you want to
run the bittorrent client on. I have two boxes running various
OS's and clients and so I have configured one box to use
6881-6889 and the other box to use 6890-6899. I did this by
configuring both the bittorrent client software on the boxes
and the port forwarding setup in the router. Once you do this
it looks like those ports are directly sitting on the internet
instead of inside of a NAT-LAN.

Another possibility is that some routers have an option to
basically do this for all ports of one PC at a time. Not
recommended as it leaves more of an "attack surface" exposed.

I use torrenflux too. I found that forwarding the ports to my knoppmyth box speeds it up immensly. Much faster than azureus, for sure.
What I do is start a torrent downloading and then see what port it is using, I then connect into my D-Link DI-624 router and forward that port to my myth box. After about 2 minutes the speed jumps WAY up. (My DI-624 only allows one port at a time, not a range, so I have to do it this way). Haven't touched azureus since.

Oh, I know processes aren't bad. But when downloading 2 torrents was taking 100% CPU usage for 12Kb/s transfer rate, I knew something had to give. It's the fact that the version of TorrentFlux I was running at the time (I don't know about the current release) was using the Python interpreted version of the BitTorrent client, which was slow and resource intensive, and it was calling that client using cli within Apache (A bad move, security-wise).

Still, I'm happier now. Or would be if BTG and LibTorrent weren't going through an overhaul at the moment. :/

Have you tried bittornado? I've been using it for a few years now (disclaimer: for legal downloads only), and find it very easy and nice to my CPUs. It's also python based.

You'd like Torrentflux, then. It's a web-based frontend for... drum roll... bittornado!

I've been using Torrentflux-b4rt on my MBE for quite a while now (> 1yr?) and I've been quite happy with it. More features than I'll ever need. It just serves up the most recent KM release and gets the occasional software app or iso image. It's been solid as a rock.
