How bnetd Developers Reverse Engineered Battle.net

battlebot writes: "O'Reilly's ONlamp.com is running an interview with the bnetd developers that goes into great detail about how exactly they reverse-engineered Battle.net. This is by the same guy who wrote the recent Salon article, though is far more technical. They talk a little bit about their legal troubles too, and even sheepishly admit that perhaps talking to a lawyer earlier in the process would have been a good idea. Has this project been successfully squashed?"

  1. The real question by Dynedain · · Score: 4, Funny

    The article says that they have made BNETD virtually indistinguishable from the real battlenet through reverse engineering. What I wanna know is, what function did they assign to the gem in the Diablo 2 client?

  2. Consulting an attorney earlier... by sterno · · Score: 5, Insightful

    If we assume for the moment that they had thought of consulting an attorney when they first embarked on this project, would it have made a difference? I mean, seeing as the DMCA didn't actually exist in '98, how could they have made some plan to defend themselves against prosecution under it. As for the straight up copyright issues, it's total hogwash, but at least they could have gotten the lawyerly advice of, "well they haven't got jack on you, but can you afford to fight it?"

    I was thinking about this earlier, and the really frustrating thing is how much of computer related tinkering seems to need to be run by a lawyer. I mean if you have a hobby like building kit cars, or constructing furniture, you have no need for attorneys. But if you want to get deeply involved in tinkering with software, etc, you suddenly need a law degree. Companies talk a lot about the damage that piracy has on the software economy, but I have to wonder how much more damage has been caused by the chilling effect on independent developers by this legal morass we call intellectual property.

      Well, I did seek some legal device back in 1998, when I receive a cease and desist letter from the Software Publishers Association. The letter (well email, actually) came less than 12 hours after I published bnetd 0.1.

      The lawyer was from the Student Legal Services office at my university, and didn't know much about IP law, but I did seek legal advice early on. :)

      This is addressed in the last part of the article:

      Crittenden: We probably should have talked to a lawyer years ago to get an opinion on whether what we were doing was legal or not. I'm not sure how much it would have helped in this case. But it might have gotten us into a conversation with Blizzard much earlier, and perhaps in a less confrontational way.

  3. blizzard's suing the wrong group by Frizzled · · Score: 5, Interesting

    warforge has been the team working on a warcraft 3 server (which caused all the problems with blizzard). they started with bnetd's code, but now the projects are basically separate.

    shame blizzard didn't do some research before turning the lawyers lose. even if they get an injunction against bnetd, they'll be shutting down the wrong group.

  4. They'll never get another dollar from me. by NoMoreNicksLeft · · Score: 5, Interesting

    I have legimate copies of every game/expansion pack they've ever produced, on up to Diablo II. Full retail price, too, not bargain bin or second hand. They _were_ the one company that you could be sure I would buy a game from, maybe not the day it was released, but I'd get it eventually.

    As I remember it, this news hit the very day that I couldn't hold out any longer for D2. Strangely, I'd never heard of bnetd until then. Being able to play on a server I could control though, would only have encouraged me even more, to buy their games. I had only played Diablo I on Battlenet once or twice, and not been at all happy... nice idea, but too many assholes. To think that I could fix that problem without extending several dozen ipxtunnels, etc... that is kickass.

    They should have hired these guys, not sued them. That would have been a cheaper way to stall bnetd, they would have gotten more for their money, and they wouldn't have pissed people like me off.

    Fuck you, Blizzard.

    To everyone on the bnetd team, keep kicking ass, and the best of luck to you.

    Its getting to the point where the open source movement will move further and further underground. All the benefits of the open source would still remain if the lead developers remained anonymous (except maybe for ego purposes). Nobody ever has, and probably won't challenge the majority of open source software, but why risk it anymore. Let the software companies and the movie industry waste a large sum of money trying to silence the small insignificant factions. If those factions ever do rise to power and the power bases lose their market as a result, then in time, most of this won't even matter.

    Take Microsoft and the northwest schools. It is not just ONE school district talking about mass migration here. If they do it, and pull it off, other districts will notice. They'll see that it actually CAN be done. They'll see that there really IS support available, and they'll see that it IS saving a lot of money, and they can safely tell the BSA to fuck off. They'll switch too. One at a time, one after another. Microsoft will lose them all. Now you have a whole bunch of high school students, ALL of them trained on linux or whatever open source suite appealed to the districts. They go off to college. You will now see the same movement there. And once that wave is done sweeping through, the corporate world is next. It really COULD start with one school district, and in 10 years, Microsoft will have completely lost their grip on the market, never to regain it.

    The point is, after a few years of this, everyone will be using open source software to some degree. People will EXPECT software to be free. And when Blizzard, or the movie industry or anyone comes along and sends out letters saying "you can't use that software" a whole lot of regular non-geek people will turn around and say "up yours!" to the respective finger pointer and tell them where they can shove it and take their money elsewhere.

    The music industry is already learning the hard way on this. They had their chance. They could have completely cornered the online market for years had they put in place a simple, inexpensive, non-intrusive music distribution system YEARS ago when they had the chance. But no, they were so concerned about rampant piracy and how it might affect their bottom line, they instead played stupid legal games to attempt to stifle the music trading. And for all the court cases, and all the laws that passed, trading has increased to massive proportions. They sue napster into the ground, 10 others pop up to take its place, only non-centralized and no way to easily shut them down. Who do you go after now? the programmers??

    Well, you can't if you don't know who they are.

    So undergound all this even potentially murky legal stuff. Wait a few years. All those who would threaten you will be overcome by the wave, and afterwards, they wouldn't dare.

      It is EXTREMELY stressful to be an anonymous developer for legal-risky work. Let me tell you, I know.

      As Jon Johansen said, in an old interview about DeCSS:
      (emphasis added)

      http://www.linuxworld.com/linuxworld/lw-2000-01/lw -01-dvd-interview.html

      Jon Johansen: I'm 16 now, I was 15 when it happened ... and the encryption code wasn't in fact written by me, but written by the German member. There seems to be a bit of confusion about that part.

      LinuxWorld: The other two people that you had worked with to make the player are remaining anonymous -- is that right?

      Jon Johansen: Yes, that is correct.

      ...

      LinuxWorld: Do you know why they want to remain anonymous?

      Jon Johansen: They are both a lot older than me, and they are employed. So I guess they just didn't want the publicity, and they were perhaps afraid of getting fired.
