Granted it's a lot of logs - but if you put in a linux+iptables or bsd+pf box as your router, you could log every connection to file - at least text zips well. store them for 6 months, only log connections which become fully established (since if you log half-open connections you'll likely be logging orders of magnitude more). It probably wouldn't take up a huge volume of space if you compress them, and you could also probably not log outgoing connections terminating on port 80 or 443 (though undoubtedly peer clients try and use those from time to time, it'd help you shave your logs if you hedge your bets that someone looking to sue your roomate isn't using 80/443 for their endpoint).

This in addition to truthfully answering lawyers' questions should cover your ass plenty sufficiently.

Agreed. My first thought was that carmakers just need to leave the sensitive/important control elements of a car decoupled from those which are network-enabled. I believe that airliners are designed similarly in that their in-flight entertainment systems are always 100% not connected to flight systems (regardless of whether or not the entertainment systems are Internet-connected, there's definitely a parallel to be made here).

While I don't care about modding systems for the purpose of playing pirated games (I own a PS3 and Wii and am fine with buying games), I think this is an important case for hobbyists/hackers and anyone who thinks they should have the right to hack on their own hardware - which as far as I'm aware is what Sony is trying to set a precedent against.

I want to be able to mod my PS3 or anything else I own for whatever reason I want - whether that's to put Linux on it or do something more unique with it as part of a research project or just for fun. The fact that this can be used for copyright infringement/piracy is secondary. It is the act of pirating the material that should be illegal and enforced, not any of the technological means that allow it to happen. (similar examples: outlawing VCRs instead of the sale/exchange of copyrighted material, outlawing torrent programs instead of the action of sharing copyrighted material, outlawing guns instead of crimes committed with guns, outlawing cars instead of hitting people with cars, etc etc.)

As such, I donated a nontrivial amount to Geohot's "give me donations to help my legal defense" plea a month or two ago. I want the ability to do whatever I damn well please with the hardware that I've purchased.

Aside: I think it's amusing that Sony requested Geohot's paypal transaction records to try and help prove parts of their case. I wonder if they'll be discriminating between "people who paid Geohot for modding-related things" and "people who donated for his defense." Clearly this should be easy based on the amounts there, but I almost wish I knew how much he was accepting for modding jobs before I donated, so that I could have donated that amount N times to approximate the amount I ended up donating, just with the hope that Sony would confuse defense donations for payment for modding jobs/chips/whatever and cock up their case against him even more.

It was actually because they had capacity issues and have temporarily reduced the number of channels available so as to not knock the whole service offline again.

For some number of companies I'm sure the publicity and thought that went into the [potential] Y2K problem helped them avoid problems. For others it didn't, but at least they knew it wasn't going to be a showstopper for them. Now, whereas Y2K was a "maybe it will impact us, maybe it won't" deal, IPv6 will eventually impact every person and business in that it requires the attention to equipment support and enabling v6 connectivity on their networks. Regardless, evaluating a company's IPv6 readiness likely won't hurt anything, just like it didn't hurt to be ready for (or better yet avoid) Y2K issues.

No, I think you were missing my point that an end to end path with a normal MTU has a slight edge over one that is slightly reduced, that's all I'm saying.

I wasn't trying to get into the details of how those mechanisms work, I understand them fine and wasn't commenting on the difference in mechanisms between IPv4 and IPv6, or commenting on the difference between IPv4 fragmentation or TCP segmentation.

I'm aware, it will be fragmented if the path MTU is reduced somewhere down the line, regardless of whether it is at an intermediate router or the original host (note that I didn't specify that it would be fragmented at the intermediate router or reduced in size at the source host after ICMP signals it is needed). Either way it makes the IPv4 path at least slightly less appealing than the IPv6 one.

Regardless, it sounds like we are in violent agreement on bigger picture

Well I didn't say "relying on the MTU" but it's better for everyone if fragmentation isn't needed. If there's no end-to-end 1500B MTU path for IPv4, then the traffic is going to be fragmented all day every day, and likely with NAT involved as well (I'm envisioning a DSLite deployment where the v4 connectivity is NATed as well). Being able to provide content over v6 avoids both of those.

I found it interesting that the article mentions 4G smartphone yahoos as being motivators for content providers getting IPv6 going (finally, I might add). That makes me think that Verizon's 4G smartphones will be like their 4G data users are now - private, NATed IPv4 access and a public IPv6 address.

From a content provider's point of view, this should make it desirable to deliver content over IPv6 since it is not NATed, etc. Hopefully more content providers become aware of this because it'll be the case with any end systems which use NAT64+DNS64 or DSLite in which case the IPv4 may not have a full 1500B MTU to the end user, etc etc.

Especially as we get closer to being out of v4 addresses I suspect v6-only hosts will be appearing and these factors will (should) start to play more of a role in the decisions that content providers are making with respect to how they prioritize deploying IPv6 to their networks and services.

The summary and to some extent TFA spout off with some FUD ("1M Internet users" not Yahoo users. "potential yahoo.com users" and some other details). I love how the summary says "at first 1M people could be shut out" but doesn't really finish the thought. "at first nobody used computers" ... and then what, the world exploded into hot dogs? dogs started using them? when starting a sentence with "at first" it makes sense to finish the thought instead of leave people hanging with some FUDish thoughts.

The article overall does a decent job of explaining the causes of this initial IPv6 brokenness, but I'm not crazy about how TFA and summary need to exclaim about 1M Internet users in order to draw attention.
