FOSS Application Under Attack by Makers of KaZaa

Famatra writes "A story from Zeropaid indicates that maker of KaZaA, Sharman Networks, has sent a Cease and Desist Letter to the maker of KCEasy because it interoperates with their FastTrack network. The creator of KCeasy says on the KCEasy website "I feel that inclusion of FastTrack access with KCeasy is not worth a legal battle between Sharman and myself". A similar issue was covered by the Slashdot story Fight On Blizzard Vs. Bnetd Case on the right to reverse engineer to create an interoperable network. Reverse engineering to be another on the list of rights that have fallen by the wayside?"

    The issue with bnetd is not "similar", except in extremely broad terms. The issue at hand wasn't hopping onto the Battle.net network, it was making their OWN network that used a reverse-engineered Battle.net engine.

    Not only that, bnetd allowed people to bypass blizzard's CD-key check, which was bad sauce. So this guy's inclusion of FastTrack operability is allowing people to steal the chance to steal software/music? And what about KaZaA-lite? This makes my brain hurt.

    Reverse-engineering may have fallen by the wayside, but it has next to nothing to do with f'n bnetd. Submitter must be applying to be a /. editor.

  2. KCEasy is just a front-end by untermensch · · Score: 4, Informative

    Sharman Networks, has sent a Cease and Desist Letter to the maker of KCEasy because it interoperates with their FastTrack network.

    I'm a bit suprised that the KCEasy authors have complied with the cease-and-desist this easily, since the above statement is not really true.

    KCEasy is simply a front-end. KCEasy makes use of giFT, which is an interface program, connecting one or more front-ends to one or more protocol plug-ins. giFT then in turn makes use of the giFT-FastTrack plugin which actually communicates on the FastTrack network.

    Anway, those of you using KCEasy might want to look into some of the other giFT front-ends, I don't know of any others for windows offhand but I'm guessing they are out there.

    Googling for giFTcurs, appolon, giftui will bring up some for *NIX.

      KCEasy is simply a front-end. KCEasy makes use of giFT

      KCEasy may be just a front-end, but it is a front-end developed by one of the guys heavily involved in reverse-engineering the KaZaA encryption algorithms (eg, /src/crypt/enc_type_*.c) for the giFT-fasttrack plug-in: mkern.

      See:

      http://cvs.berlios.de/cgi-bin/viewcvs.cgi/gift-fas ttrack/giFT-FastTrack/src/crypt/

      Maybe the KaZaA people are miffed at his reverse-engineering ways and chose to attack here rather than at the gift-fasttrack plug-in level?

  3. Latest threat to P2P comes from within by Sanity · · Score: 5, Informative
    This is just one example of the increasing threat that Kazaa, or more precicely the companies around it, pose to innovation in the P2P space.

    Perhaps the best example is their aquisition of patent #5,978,791, filed in 1997, which claims to cover the retrieval of a file across a network using a hash of the file's contents.

    Set aside, for a moment, that this technique is completley obvious and has been around for decades (the earliest reference I can find is the Xanadu project from the early 90s - but I haven't looked very hard), and consider the fact that these guys could use this patent to effectively shut down almost anyone that comes up with a P2P app that doesn't have the funding to fight them in court (since most if not all modern P2P apps use this technique).

    The bottom line is that companies such as Brilliant Digital Entertainment (the same nice people that were behind the adware that Kazaa is now famous for) are almost as much a threat to P2P as the better known people everybody loves to hate.

    If anyone is interested, here is a more detailed article I wrote on the subject.

  4. Re:reverse engineering a right? by MathFox · · Score: 4, Informative
    In the Netherlands it is legal (under certain conditions) to reverse engineer a program "to create an interoperable program". I have all reasons to believe Markus Kern when he sais that his reverse engineering of the Kazaa network is legal in Germany.

    The law in the USA is quite different in this respect and it could be that you'll be fried when attempting such a thing there. (Jon Johansen was acquitted in Norway for DeCSS, while those in the US that only linked to it were convicted.)

    IANAL, if you want to try this at home see one (a lawyer) first.

  5. Reverse Engineering is legal, but not access by EaglesNest · · Score: 5, Informative
    Under U.S. Copyright law, fair use allows reverse engineering of funcational components because they are ideas (or facts) not expression. However, a provisions from our friend the DMCA (17 U.S.C. 1201) makes it illegal to bypass an overt technological protection that restricts (a) access or (b) protects the rights of the author. Think of this as breaking open a safe (illegal) to get to something inside that you're allowed to copy (legal).

    As for intruding on a private network, the network is composed primarily of users, if I'm not mistaken. Still, companies like E-bay have been successful in using trespass (to chattles) to keep people off their servers if they make it clear that they don't want them on there.
