  1. If domain names were covered by the UCC on GoDaddy VP Caught Bidding Against Customers · · Score: 2, Interesting

    If domain names were covered by the Uniform Commercial Code (UCC) there might be imputed into the contract an obligation on the part of GoDaddy to engage in good faith behaviour. But it is unclear whether domain name rental falls under the UCC, and the UCC is not all that U(niform) across the states.

  2. Serial numbers in ARP packets on Hiding Packets in VoIP Chat · · Score: 2, Interesting

    There are sometimes other places to hide data:

    I can't remember whether it was FTP Software of NetManage, but one of those used to hide the serial number of the software in the bits between the end of broadcast ARP requests and the end of the Ethernet frame.

    That way they could check for duplicate license keys on the same net without bothering anybody. Only worked across the broadcast domain, but that was adequate for that purpose.

    There's lots of other places too.

    RTP packets have optional extension headers that can be used, DNS can hold extra information in parts of the query and response packets - I once encountered someone tunneling music feed via buggered DNS packets. (It became very visible when it caused a Cisco firewall to go haywire.)

  3. Re:Use randomized time rather than even spacing on Why BitTorrent Causes Latency and How To Fix It · · Score: 3, Informative

    Give pchar a try. Just because it's not being upgraded hardly means that its data is not more accurate than ICMP echo times. Pchar is slow; it emits over 1400 probes per cycle. That's why it can take 15+ minutes to characterize each hop of the path.

    Pchar is derived from Van Jacobson's pathchar; there is a lot of very good and very deep knowledge behind those tools.

    Yes, Ping is better than nothing, and a lot better than things like DNS round trip times. But if you are probing basic connectivity of a single hop the best protocol is to use is ARP.

    But pings, as I mentioned, are often rate limited or slow-path switched or even blocked. And an increasing number of folks don't even reply to 'em. Moreover, they usually don't reveal the fate of large packets to things like MTU constraints or very noisy wireless paths that tend to clobber larger packets (as in bittorrent or HTTP) more often than small ICMP packets.

    By-the-way, a lot of folks have commented on how to use the Linux traffic control system to manage outbound traffic. I commercially build a small box to do this for folks who don't want to mess with "tc" commands.

    But the bigger issue for outgoing links is that the providers don't keep the outbound bandwidth constant; many providers tweek the outbound pipe size fairly rapidly. This makes it quite difficult to maintain the aggregate outbound rate so that the queues build up in the user's box (where the user can do sane management) rather than the provider's box (where the provider does whatever is good for the provider.)

  4. Use randomized time rather than even spacing on Why BitTorrent Causes Latency and How To Fix It · · Score: 5, Informative

    We long ago learned that when inserting time between protocol events that it is far better to use a time randomized between an upper and lower bound than to use a repeating interval.

    When fixed repeating intervals are used, separate instances of a protocol (and other protocols that use repeating intervals) slowly tend to fall into lock-step patterns with pulsating waves of traffic in accord with those patterns.

    In other words, fixed protocol timers can create the traffic equivalent of the Tacoma Narrows bridge.

    By-the-way, ping (ICMP Echo request/reply) is a terrible way to measure network latency. ICMP is often a disfavored form of traffic as it crosses routers, sometimes even rate limited.

    There are better tools for measuring link properties, for example there is "pchar" - http://www.kitchenlab.org/www/bmah/Software/pchar/

    I worked on a method to do even better measurements, but I put it aside several years ago: Fast Path Characterization Protocol at http://www.cavebear.com/archive/fpcp/fpcp-sept-19-2000.html

    ICANN also forces another tax (this one going to ICANN) of $0.20 per domain name - which amounts to about $20,000,000 in additional yearly taxation already in place.

    We are entering an "interesting" era in which the authority and power once held nearly exclusively by national governments is eroding, due to the internet and multi-national corporations, and flowing into the hands of privary bodies such as ICANN.

    There have been private bodies that have become legitimatized and have demonstrated that they can be trusted with authority - the Red Cross comes to mind as one example. (It's now a body that has treaties behind it, but that was parallel to the growth of its legitimacy.)

    We need to reach back to the late 17th and early 18th centuries to re-learn the lessons - from folks like Voltare and Madison - about how to structure bodies so that they have internal tensions (think the three branches of the US gov't) and other mechanisms (such as a constitution that enumerates powers and limits) so constrain improper use of the power that a body has.

    How this is done in specific terms is the issue of internet governance today. But unfortunately the "stakeholders" (such as the intellectual property protection industry) are well organized and tend to trump the less organized, and less able to afford to attend, members of the public.

    This isn't easy stuff.

    ICANN is already costing you and me - the people who buy domain names - something on the order of $500,000,000 every year in hyper-inflated fees that go directly into the bank account Verisign and the lesser registries. ICANN also requires you and me to path a tithe of about $0.20 to ICANN every time we register a domain name.

    And ICANN has created a regime that restricts DNS on behalf of the trademark industry in ways that RIAA can only envy and wish they had such restrictions over music distribution on the net.

    And despite that, ICANN has no means for the public to engage in its decision processes beyond remotely observing and trying joining an ICANN approved committee that, in turn joins another ICANN approved committee, that, in turn gets a seat on another ICANN committee, that gets to nominate members of the board of directors. Even citizens of the old USSR had a more representative system.

    Once upon a time ICANN did have directors elected by the public - I was the one for North America - but when I wanted to look at ICANN's financial records, a thing quite proper for a director to do, ICANN reacted by erasing all elected seats.

    So, if the US government drops its oversight, limited and self-interested as it might be, where will oversight come from?

    Do we really trust that ICANN will be any more self-responsive to the community of internet users than was Enron or MCI/Worldcom to their shareholders?

    It does seem that the quid pro quo that the US ought to require as the price of freedom is that ICANN adopt mechanisms that really and truly make it responsible to the public.

    There is, of course, the further question of where ICANN might obtain immunity against anti-trust laws should the US gov't drop its protective cloak - ICANN does shape the domain name marketplace, set prices and product terms, determine who may and who may not be vendors in that marketplace, and in other ways restrains trade in the world's only viable marketplace of domain names. Several experts in the field feel that ICANN may be vulnerable as a combination that acts in restraint of trade.

  11. Data mining on Domains May Disappear After Search · · Score: 4, Informative

    It has long been rumored that domain name registries snap up names when they see signs of interest. Unfortunately ICANN's committees don't have the tools to really open up the clamshell and see what is really going on deep inside registries and registrars.

    However, there is another matter - that of data mining of the query packets that arrive at root and top level domain servers.

    ICANN's contracts do not prohibit data mining of the query stream, in fact they openly permit it. Thus Verisign has the right to look at incoming queries and generate a body of information about what domain names are being uttered by users. It's not a big step from that to come up with a list of names that would be nice things to have if one wants to spatter up a bunch of Google Adsense ads and collect click revenue.

    (Also, because the entire domain name, not just the top level parts, hits root and top level domain servers, through a bit of statistical reduction, one can produce a data stream that is of interest not only to paying marketeers but, perhaps, to certain national intelligence agencies.)

    This, of course, took some careful timing.

    And it relied on kernel weakness - the weakness of leaving the user parameters in user accessible memory while they were being validated. The fix was to have the kernel move the call parameters into its own memory before validating.

    And on a multi-CPU unit (those, too, existed back then) that copying of system call parameters had to be to a different place for each CPU, else synchronized calls from different CPU's could be a weakness.

    Well, this is getting a bit off topic - but OK.

    There are several indicators that suggest that the actual cost to provide a domain name registration at the registry level is only a few cents per year (I estimate that it is less than $0.03).

    ICANN requires that Verisign receive more than $7 for each name in .com each year. That's a fiat transfer of roughly $6.97 from you and me to Verisign every year for each of the 60,000,000+ names in .com. That works out to very roughly $400,000,000 per year. Add in similar situations for .org, .net and you come up with half a billion $ each year.

    Even if I'm off by an order of magnitude, i.e. that it's merely $50,000,000 a year, we're still talking about a lot of money that is being pumped.

    Now, ICANN is run by incumbent registries, registrars, and business interests that like the status quo. They set domain name price floors (the registry fee), sales terms (such as UDRP, whois, and terms of 1 to 10 years in one year increments), as well as decide who may and who may not sell names in that marketplace, who must be used as resellers, and, on top of it all, ICANN extracts an override on all sales. It looks like and smells like a combination of insiders who restrain the trade of domain names. Illegal?

    And remember, at least with telcos who engage in non net-neutral practices and with Microsoft, at least you and I, in theory, can buy stock and have a say in what they do (in theory.) In ICANN we don't even have that theory because ICANN has eliminated any real form of public role in its decision making processes.

    Consequently today we have more than 130 root servers scattered around the world.

    That's good. It tends to localize the damage caused by attacks.

    What is not good is that these root server operators, although they today operate to the highest of standards and with the highest degree of integrity, are not required to do so in the future.

    For example, several root servers are operated by the US military establishment or by other branches of the US government and are thus subject to being "adjusted" according to military, political, or Atty General Alberto Gonzolez's latest desire to do data mining.

    Nor are the root servers required to play fair and respond to all queries with equal dispatch or equal accuracy no matter the source or the name being queried for.

    Nor are the root servers off limits for sale to companies like Microsoft or Google who could use them for commercial data mining.

    Many people believe that ICANN serves as a kind of fire marshall, overseeing that the root servers are operated responsibly and that the root server operators have access to the resources they might need to recover from a natural or human disaster.

    But that is not the case. ICANN has abrogated that role and has engaged itself as a protector of trademarks and US cultural values.

    Over the last few thousand years we've learned that it's best for long term stability to build institutions and not depend on individual people.
