BitTorrent Servers Under DDoS Attacks

jZnat writes "CNet News.com reports that popular BitTorrent tracker hosts such as Suprnova and LokiTorrent underwent DDoS attacks on Wednesday (I'll bet you noticed). The culprits are primarily unknown, but these sites were flooded beyond control from the attack. This appears to be striking an interest in revising the BT protocol and Suprnova's interest in making their own protocol."

Corperations however are not people, despite how they may be treated by the law, and I think that Bittorrent is by far less damaging to corperations than spam is to the productivity of people (not to mention their happyness).

    The corporate world isn't trying to control the dissemination of information. They are protecting their profits. It's not necessary for them to have symetric lines for most DSL customers as their downloading habits are very much skewed towards the download bandwidth. It's also cheaper for them to provide aDSL service then it is to provide sDSL. Upload bandwidth I beleive is more expensive, bit for bit, then the download. There is also distance limitations on the speeds available. sDSL may work well at relative slow speeds, but once you get to faster speeds, the upload speeds greatly reduce. Verizon offers download speeds between 768kbit@18,000 feet and and 7.1mbit@9,000 feet. There is no way that they can provide 7.1mbit upload speeds@9,000 feet.

    Dynamic IP addresses are used for several reasons. The first is that it discourages customers from running servers. It doesn't eliminate it, but it makes it more of an inconvienence.

    Those that truly need static addresses typically are willing to pay a premium for it. Business customers for instance. They can't afford to have e-mail not delivered or their website unavailable during that short period when an IP address may be updated. In this case, it is about the $$$. Most ISPs will renew a lease so in effect your dynamic address is typically static, but it's not guaranteed though.

    Dynamic addresses are also cheaper for the ISP. In many cases the addresses aren't actually owned by the ISP but instead "leased" to them. The ISP ends up paying for each one of them. If they give everyone static, they need to have 1 or more addresses per customer. If they hand them out on a as-needed basis, they can save money as not everyone needs one at all times. At most they would need the same number of addresses as what they would need with static. At the least, they would need 1 per active customer. As leases expire the addresses can be reused, reducing the total number of addresses needed over the long term.

    PPPoE is used because it can simplify the back end support and accounting process for the ISP as they can use essentially the same system for both dialup and DSL customers. If everyone is essentially treated as a PPP customer, regardless of the actual connection method, the same authenticaion servers can be used, the same tracking/billing servers, etc. ISPs didn't have to get another set of conectivity to migrate dialup users over to DSL.

    Adding a static IP is something they *can* charge you extra for and people will pay it. So they do.

    In the UK, my ISP gives a free static IP if you ask for it, so I have one. I think they have different cost models than the states, ie. no-one thought to charge loads for a static IP, and now no-one can do it because customers would migrate to the other ISPs.

    No you don't. An ISP never has as many IP's in their pool at they have customers. They only have to keep as many as they will ever have connected at one time. With cable and DSL that's a higher percentage than it used to be with dial-up, but it's excess cost to keep an IP for each customer.

Just post something some op doesn't like to a channel, and you'll see just how childish those people almost always are. Rather than stating in an adult manner something like "in the past we've had problems with X due to Y, therefore we no longer allow X on this channel," you usually see immature idiots spouting random insults.

    As an example, I used to be an fserver on #bookwarez on Nullus. I gave-up when the ops went from people that cared about spreading knowledge to people that care only about how many people they can make mad. For example, ask a question about why some idiot put content in a proprietary .doc format or in a proprietary .chm file that only one reader for on OS can read, and you'll probably get banned. Ask why looking for books in #bookwarez is now verboten (it's allowed in #bw), and you'll probably be banned. It's ridiculous.

It's those small minded people that have kept IRC from becoming mainstream. No one likes to go somewhere that is ruled by punks screaming "Respect My Authority!"

    My dynamic IP changes once a year. It has nothing to do with running a server (dyndns anyone?) - if they wanted to do that, they would be blocking inbound ports. If anyone remembers @home, you could actually configure your machine for static once you received your IP (which was necessary due to the stability of fetching a DHCP address from the other side of the continent).

    The reason for DHCP? As the cable companies reconfigure networks (splitting/combining areas), it's sometimes necessary to change IP blocks (keep in mind, their network is heavily tied to location). Is it easier to change a DHCP server and release/renew, or notify hundreds of customers that their IP is changing? For the same reason, I often run my networks entirely on closed DHCP (using the MAC to IP mapping)

    PPPOE has more to do with the fact that various companies resell or piggyback from the phone company, instead of sticking their own infrastructure in each CO. Static requires more work to setup and maintain (routing the line to a different DSLAM/network/etc)

    Maybe.

    If that was a material contribution, there was a direct infringement, and you had actual or constructive knowledge of such infringement, then yes.

    My favorite case on this -- because it's clearly written and tends to shock people; I don't actually like the holding -- is Intellectual Reserve v. Utah Lighthouse Ministry.

    Basically website A posted a link to website B, knowing that website B had posted copyrighted documents in an infringing manner. Because people reading website A were encouraged to go to website B, and because reading the documents at website B would constitute an infringing reproduction of those documents, and because website A's owners knew of the infringement -- they were felt to be substantially likely to themselves be infringers.

    N.b., you're more likely to be sued civilly than prosecuted criminally.

    Of course, the bare statement that suprnova exists really wouldn't be sufficient. But saying something like 'You can download movies from suprnova' might. In the end, there are no magic words. Courts'll look at the character of what you said, your audience, etc. If you're a model citizen (e.g. a New York Times with an article about piracy since its' a newsworthy thing) then you'll probably avoid liability. If you appear disreputable (e.g. a 2600 posting links to suprnova and talking about how people ought to pirate movies and stick it to the man du jour) then you'll have a harder time. This is because in the latter case -- aside from not getting much sympathy because you seem like a bad guy -- there probably is a higher chance of material contribution.

    For suprnova themselves -- they'd be toast. You can't possibly say that hosting torrent files is not a material contribution. They'd have to argue the knowledge angle as far as contributory liability goes. I think it would be hard.

    This is why they're not in the US, IIRC. They wouldn't have a chance here.

Say to shut down a spam zombie computer or to get the street address of any node on the net? Well.. aside from that anecdote I think this calls for the following analysis.

    In the following excerpt by the past head of the CIA,

    line 1 is either (a) silly, (b) evil, or (c) intelligent depending on your point of view. Silly because it sounds like sticking your finger in a hole in a dike; evil because it could mean anything draconian; intelligent in case it happens to be only talking about companies running critical infrastructure, who would maybe have to take rigorous security audits or not be allowed to have those facilities online. (c) makes sense but is the lowest probability, since the talk was made intentionally very vague and without press.

    Line 2 similarly is (a) silly or (b) evil if talking about anybody not running sensitive infrastructure, and (c) intelligent if talking about the critical facilities. Line 3 sounds like he wants software companies to be more careful about security. Sounds like a good thing but then again what the CIA calls security is smoke and mirrors for ulterior motives, control, and punitive damage (until recently only outside U.S. borders), whereas most other people would call building strong personal firewalls and encryption security because it keeps the individual owner safe. No stomach for multiple choice here. Perhaps he has an occupational disease which prevents him from saying anything clearly and putting himself on the line? No chance of rehabilitation for this guy. Even if he was I guess the successor of the President's father or something like that. Maybe he should take up skydiving?

    My analysis is that this is a retired professional scary guy trying to be relevant but incapable of doing anything but sounding silly or scary to anyone with a brain. People without brains generally think he's smart, etc. Which is too bad because if he could learn to speak more clearly he would be more effective and might have something useful to say about dealing with cyber-security threats (though I'd rather hear from the NSA's linux team about it than from a failed spymaster). This is why businesspeople in the real world never listen to government types. They can never say anything useful about anything directly, it is always vague scariness about vapor policies with a hint of powerplay behind it. BORING 90s SHIT!
