IPv6 Tricks

IPv6 just turned 30 and still hasn’t taken over the world.

As usual, the Hacker News comments are full of utter idiots. More than half of the people there (mostly the ones praising IPv6) who speak authoritatively about networking know fuck-all about it. Which is the norm there.

Like this fucking clown talking about IPv4 and NAT. His claim that โ€œthe connection will just head right on through your routerโ€ is 100% false for a normal NAT gateway. Doesn’t matter where the traffic originates as as long it’s coming from a public IP. His comments are fully wrong. Packets arriving from the internet are addressed to the routerโ€™s WAN IP. Without a DNAT/port-forward rule (or an existing NAT state entry that matches), the router does fucking not โ€œroute them onwardโ€ to some LAN host. There is no destination inside to route to because the destination is the router itself. This cannot, cannot happen. Idiot.

The comment how about how โ€œNAT only changes the source addressโ€ is also wrong. Typical residential NAT is always NAT/PAT (address and port translation) and is stateful.That means it creates a mapping only when an inside host sends outbound traffic first and uses that mapping to translate inbound return traffic. Unmatched inbound traffic is dropped because it canโ€™t be translated. Period. Therefore, that makes NAT a very effective security measure for essentially free.

From the outside, you simply cannot open a new TCP connection to an arbitrary PC on a residential network behind a simple NAT without port forwarding or some other explicit/implicit mapping mechanism. Thus, Dagger2 is a clown idiot, as mentioned above.

Motherfuckers are always like, “NAT is not a firewall!” And never, ever, ever, understand how NAT actually works. Blows my mind.

Certifiable

Changing the cert expiration period to 47 days is a good example of everything that is wrong with my industry.

This is a pointless change that will cause untold chaos, issues and labor with the most likely outcome being an overall decrease in security — all for the only the appearance of increased security while actually doing worse than nothing.

A lot of effort and noise, achieving only harm. Yeah that’s how it’s working these days in my career.

Slip Slop

Most written media is mid-wit slop, because thereโ€™s a literacy gate just to participate at all. If you canโ€™t clear it, youโ€™re not in anyone’s view, and if you can youโ€™re funneled into a narrow band of โ€œreadableโ€ output.

So the people who can barely read are aspirants hoping for the day they can finally understand the slop. Meanwhile, the mid-wits who are the actual target audience treat the pap like the ceiling. Itโ€™s all they can grok, and they get offended the moment you suggest they stop accepting spoon-feeding and look past it to something more complex and accurate.

So for those reasons slop is about all there is.

Lost World

To think that my childhood and the childhood of everyone I knew in the 1980s is now some mythical lost world that Gen Z clowns do not believe even existed. However, by the time I was around 9, I could ride my bike anywhere I wanted. It was the same for all the other kids I knew about. It was absolutely, completely normal.

Racing Where

It’s hard to believe the “race doesn’t exist” propaganda when a genetic test can determine it quite reliably.

Same Lies

Yes, this is all just part of the left’s ongoing mendacity about how “everyone is exactly the same.”

Supposed

โ€œPeople are instinctively curious: they want to learn, and they learn best by active self-directed exploration of their environment. People strive to master their environment: they like to have a sense of control over what they are doing, to see and understand the results of their own actions.โ€

That’s from the official Apple user interface guidelines. The first part is certainly untrue, as much as I like the whole work. About most things, including their computers, people are definitely not curious. In fact they will go far, far out of their way to make sure they know nothing of how it works or how best to use it.

Adults at least are generally very incurious in my experience.
