BitTorrent's Creator Bram Cohen Interviewed

      Do you know anything about BitTorrent? Each piece of the file is identified by a hash stored in the .torrent file, and is verified before being uploaded to others. As long as you grab your .torrent from a reputable source, you should have nothing to worry about.

    The article is very thin on the legitimate uses of BitTorrent. Just last night, I wanted to download the Unreal Tournament 2004 demo... and despite the fact there were literally hundreds of mirrors, I couldn't connect to many of them, and those I could connect to were utterly hosed. So, I looked for a torrent for the file, and a few minutes later, I was done downloading it.

    Yes, you can use BitTorrent to steal stuff. But, all of the p2p programs are basically a mix of the roles of ftp and irc. BitTorrent is slightly different - it's a mix of p2p and the web, making a quick and easy means to find whatever you want. A great amount of content is completely legit, and BitTorrent is a dream come true for those times that everybody wants a certain file. I didn't expect NYT to focus on the good aspects of the program, but they didn't even mention how amazingly useful it actually is.

    Big files, probably. If he wanted it to be used chiefly for big illegal files, he wouldn't have made the system require a centralized tracker that can be shut down and it would've had at least some semblance of anonimity.

    As it stands, BitTorrent is no better at distributing copyright infringing content than HTTP is when it comes to evading the copyright holder.

  16. Should be used for Linux Distributions by mcrbids · · Score: 5, Interesting

    As I sit here, getting packages at a mightily slow 8 k/sec via Fedora's Red Hat Network, I wonder why this must be.

    Why don't tools like yum, up2date, and apt incorporate BitTorrent concepts to download packages and files?

    If there was an option when installing Fedora or Debian to "share XX Mbytes at YY kbps" I'd be perfectly happy to donate 50 MB of disk space and 5-10 Kbps of bandwidth to the cause. That's be anough to reliably provide a few packages for redistribution.

    Multiply that by the number of Linux installs, and you have a lightning-quick package delivery system.

    Imagine apt-get or up2date ALWAYS able to saturate your broadband connection when doing an update!

    Why is nobody doing this? Security isn't an issue, since BT uses SHA1. Source isn't an issue since BT is open source. Isn't the RHN stuff already written in PYTHON?!?!?

      The problems seems to be with the inability of BitTorrent to serve directory heirarchies, and the difficulty of generating .torrent files for a large repository of 10,000 files or more, plus the resource usage of running a BitTorrent tracker for each file.

    The article makes an interesting point that I'm sure a number of /. users are aware of that bittorrent is not anonymous at all. Many less technically savy users made that mistake when using Napster and Kazaa and got screwed by the RIAA. Now while you're uploading and downloading you have no control over who sees your IP but I'm curious to know if trackers hold on to this information after you disconnect, or if sites like suprnova.org keep track of who downloads what torrent. Does anyone have some insight into this?

      None of the file sharing tools currently available provide any kind of anonymity. You may be anonymous while browsing for files and doing searches as these usually flow through somekind of distributed network, but once the downloading (or uploading) starts the other side will know who you are as they have your IP address.

      The main reason for this is lack of bandwidth. If you want anonymity even while downloading, someone else will have to act as an intermediary (preferably more than one). Those intermediaries though will have to download some data, and then upload it again to you which gains them nothing (in other words, it wastes a lot of bandwidth). Everyone will need to provide some bandwidth for this purpose to make this even remotely feasible.

      Only Freenet currently does this that I'm aware of, and it's a lot slower for that very reason. Bandwidth however seems to be subject to Moore's law; soon there should be plenty of it, and then you can have real anonymity.

    Why anyone would peg their bandwidth for 2 days to grab a flick when you can rent it and burn a copy is beyond me.

    Bittorrent shines for grabbing stuff, sure, but I think most people just collect crap, then burn it to disk or throw it on a HD and equate that with penis size.

    So, Movie Industry, I really can't see this costing you zillions, or hundreds of thousands for that matter.

    The people who want to will go to the theater, buy it on DVD, or rent it. The ones who don't, won't.

    Again, if you're going to hunt people down, go after the pressing plants making thousands of copies AND SELLING THEM!

    For his part, Mr. Cohen pointed out that BitTorrent users are not anonymous and that their numeric Internet addresses are easily viewable by anyone who cares.

    The evil genius of the whole BitTorrent idea is the lack of anonymity. Like the article points out, it's perfect for Linux distros and anime fansubs. But if you think nobody can know what you're sharing or who you are, you're a fool.

    I use the Mac OS X version, so I don't get to see this, but a friend showed me his Windows version and you could not only see who was connected, but what their bandwidth use was too. Apparently some people know how to become super-leeches. They'll appear, and everybody else's download speed suddenly goes to zero while they suck up the whole file. Then they go away. That this is even visible to a regular client should be thought-provoking.

    It took me months to find it (because nobody bothered to document it!), but fortunately I found the bandwidth limiter in the OS X version. (Click on that widget on the right side of the window title bar.) Now I can seed files without completely hosing my DSL connection.

    The thing I think I like most about BitTorrent compared to other "forced sharing" models like Napster is that you get to choose what you want to share. You go to a tracker and see "hey there's no seeds on that one show I like", then share the file at 5K. That way even the leeches have to wait. Animesuki.com even has a "seeds needed" page for anything that's worse than about 10 or 15 to zero.

  24. Torrent pool by greg_barton · · Score: 5, Insightful

    One big problem with BitTorrent is the opposite of normal client/server file sharing: if a file isn't popular, it downloads slower.

    Why not extend the concept to a set of files? Who says that the file you download also has to be the file you upload? If a site is offering a set of torrents, maybe while a client is downloading the most popular file of the moment they can be serving portions of less popular files. (9 to 1, popular to unpopular maybe, if another client is uploading them, that is...) Sure, that would take some bandwidth from the popular files, but they have enough to spare.

    For example, I just recently downloaded the Mandrake 9.2.1 power pack ISOs for club members. Download time sucked! If that torrent could share bandwith with the public Mandrake 9.2 ISOs, that'd be keen.
