Why would you trust the author's opinion about the ability to take advantage of the system? Microsoft says that their software isn't buggy and works, Adobe says that Premiere doesn't crash, Theo says that OpenBSD is immune to root exploits. All of them can say whatever they want, but it doesn't make it any more true.

BogoSort: Well, BT took 5 years to Research and Develop, it's commands and systems are like DOS, ever tried hacking DOS? Nope, don't think you can. Same thing here for BT... Many Authors say that their product works... but BT HAS BEEN TESTED. Most Anime Digi subs are now spread using BT, it has proven to be a cheap and ideal solution to serve many ppl. Of course, BT will always be upgraded to meet the demands of the future. And people like you are simply not programmers who can understand that this people which developed the software for you spent time, money, energy and blood making these programs so that we can make our AMVs and better utilise our computers. Without them, we can kiss out AMV making goodbye so cut them some slack.

First of all, I have done a bit of DOS hacking back in the day. Course you do have to remember that DOS doesn't really do networking well at all, and once you have console access, breaking into the machine is pretty trivial no matter what you do. BT is probably more more closely related to a Unix daemon, and I have yet to see one ever that has never suffered from any exploits or DOS(Denial of Service) attacks.

Now a bit of history. BSD has been around for 25 years, with a userbase that far exceeds that of BitTorrent by many orders of magnitude. This userbase has TESTED BSD and tried to hack it, and the bugs in it get fixed as they are discovered. In fact, OpenBSD, which is an offshoot of the original BSD code has teams of coders auditing the code, and reauditing the code constantly in the hopes of removing any possible expliot. This is a far more thorough search than I suspect that the author of BT did.

You have to keep in mind the difference between different levels of works. There's the base level where it provides functionality. Microsoft products, Adobe products, and BitTorrent all easily provide that. Another level is internal stability, where the program doesn't have internal problems and die every now and then, that depends on the particular product from the companies, but I'd presume that BitTorrent is stable. The final level is external security. I have never seen anything that is completely secure from external attack. By virtue of having human coders they are bound to make mistakes of oversights that will result in exploitable bugs.

I happen to be a programmer, who also happens to take an interest in security. The first rule of security that I learned is that nothing is secure. If it wasn't for my job where I program, the time that I spend having a social life, or the time that I spend working on amvs nowadays, I'd take you up on your challenge to try to find way to abuse the system.

Personally I think that BitTorrent is a fabuluous idea and works wonderfully. However I do have to dispute claims like "impossible to be hacked" or the less strong "impossible to be abused." Such things are never true when many competent people are try to prove that this isn't the case.

klinky, do you have more stats ?
home many people have downloaded entirely the file ? What is the average dl speed ?
Can you get these pieces of info ? I'd like to "see" the usefulness of this technique compared to other p2p apps.

I've been looking into getting more states, like the ones they have off animesuki, but I've not looked very hard :| I'll loook into it more today.


As for BT. There may be a way to prevent leechers from hopping onto a Torrent and leeching the stream w/o giving anything back. The fact that it's open source only leads to this being more of a possibility. But if they did implement peer-tracking in the tracker, they would want to ask other peers about a certain peer instead of asking that peer directly, since the peer could probably just spoof its upload rate.

BT was written in Python and comparing it to dos is o_O. Dos was a OS, it's far bigger and far more complex and there were viruses and exploits for DOS back in the day. However people did that even with out the source to DOS.

HammerNode(hn.org) domain name provider is really shitty. But I liked how easy the name was to remember.

I've also had a dynamic domain through dhs.org, but it's katsuragi.dyn.dhs.org which is more to type then coolantx.hn.org. :cry: '


But anyways. If you're having trouble getting the download or you're sick of getting the little red error msg. Cancel your download. Goto either

http://katsuragi.dyn.dhs.org/BitTorrent/

or

http://kproject.home.attbi.com/bittorrent/

Click on the download link again and save it over the same file you were downloading before. It should start resuming with the new domain name. So it will try to talk to the tracker @ katsuragi.dyn.dhs.org instead of the crappy coolantx.hn.org.

It sholdn't affect your download or the file or anything. It should the torrent more stable though since you'll be able to talk to the tracker when you need to rather then when hn.org feels like translating the domain name.

Actually regarding cheating on bittorrent, a few people just told me that they have a hacked client which allows you to download without uploading :\ This really saddens me :(

Well, don't worry, Bram made the system, he will do something about it, possibly make a server client for hosters to kick off leechers, if he doesn't, I might modify my tracker anyhow to do that.
