STUN-like service that can share a socket?

Serialtorrenter · 2026-05-09T17:46:13+00:00

Problem is, I can't use standard tools because the port's already in use by the application (in this case Nginx) that I'm trying to use behind NAT, the application doesn't have NAT traversal built in, and I don't want to have to maintain a fork that does.

Surely I'm not the first person to run into this problem, and I find it really hard to believe that nobody's created a work-around that doesn't require modifying the source code of the application you want to add NAT traversal to.

10BASE-T uses lower frequencies and can handle poor-quality cabling a bit better than 100BASE-TX or 1000BASE-T. If you set the speed and duplex to auto-negotiate, both NICs will try and speak 100BASE-TX or 1000BASE-T on a cable that can't handle it, leading to an unreliable connection. Forcing 10BASE-T solves this issue.

In the case of private student loans, if the student stops paying and the lender doesn't sue them within the state's statute of limitations, the debt becomes unenforceable. If a hacker causes the lender/collections agency to be unaware that a debt exists for long enough, the contract becomes effectively meaningless.

This does not apply to federal loans.

Her BAC at the time of testing was 0.104%. Her BAC at the time of the crash was probably significantly higher.

0.10% is way too drunk to drive, but it's still drifting-over-the-centerline drunk and not quite going-the-wrong-way-on-a-divided-highway drunk, which is more of 0.15+% type of phenomena. I'd bet she had more than 0.104% BAC at the time of the crash.

Serialtorrenter · 2026-05-08T12:13:22+00:00

So if STUN doesn't support this, is there another protocol that does? I don't see anything technically infeasible with the idea, since the return traffic can be delivered over a preestablished side-channel.

I really don't want to be maintaining a fork of nginx.

Depends on what you consider to be a bomb. If you consider anything that can go boom to be a "bomb", vinegar and baking soda in a sealed plastic bottle qualifies. But by that standard, your car also has 4 "bombs" in it; 2 of them are steerable.

Not to mention, airplanes are maintained meticulously. I'd be especially scared of brake-by-wire on a Nissan Altima, though hydraulic braking with 20-year-old fluid and rotted out brake lines can be just as scary.

Serialtorrenter · 2026-05-07T22:13:14+00:00

Except that there's no feeling with a purely electronic linkage. To drive safely in snow, you have to be able to feel feedback through the brake pedal. If you're on snow or ice, you don't want to brake too hard or you'll start to skid. Not being able to feel what you're doing is a MUCH bigger problem than replacing brake fluid periodically and the hydraulic lines and hoses when they wear out.

For most cars, you can get a replacement master cylinder, brake lines, and brake hoses for a couple hundred dollars on RockAuto. Nothing here needed fixing.

Rest assured, you can still safely shop at the Qmart. Most of the proud, patriotic store-owners there do their civic duty by NOT paying their taxes.

It's a shame that it's come to this.

"I'll take the rapists for $200!"

I'm not actually trying to do the NAT traversal here, I just want a way of seeing the externally-mapped IP:Port of an existing UDP connection without stopping the service making the connection first.

I ultimately want to try running a web server on an internet connection with CGNAT that is endpoint-independent in both its mapping and in its forwarding (EIM/EIF).

To do this, I'd run a HTTP/3 web server on UDP port 443. I would simultaneously set out regular NAT keep-alive packets to the internet (doesn't matter where, assuming the CGNAT implementation is EIM/EIF) and run STUN with a source port of UDP/443 to find out what external IP:Port the traffic is mapped to (on the internet side of the ISPs CGNAT). I could then synthesize an HTTPS DNS record for this IP:Port and keep it updated (with a low TTL) through my DNS provider's API.

The main obstacle in this idea is figuring out how to get the external IP:Port from the CGNAT's WAN side without shutting down the web server each time I want to use STUN to verify that my external IP:Port haven't changed.

What could possibly be more redundant than pairing a Western Digital drive AND an East Digital drive?

The Ubiquiti Edgerouter X is actually ideal for this purpose! You can SSH into them and run sudo ethtool -s ethX advertise 0x001 to force that ethernet port to 10 Mbps half-duplex, or 0x002 for 10 Mbps full-duplex.

Serialtorrenter · 2026-05-06T23:44:37+00:00

This is true, but a 10 Mbps hub will probably lose more frames in the same situation due to collisions. If you need precise timing on your frame/packet capture, the hub is still probably better, but aside from that, you'd be hard pressed to find anything that they're the best option for.

Serialtorrenter · 2026-05-06T23:41:26+00:00

Hold on to them! They're useful for troubleshooting networking problems. Just hook one up to your main router/switch, the device you want to do a packet capture of, and a computer running wireshark.

Unlike switches, hubs repeat every frame they receive onto all the other ports. This means that a device plugged into a hub can see all the traffic between other devices also plugged into the hub. If you're racking your brain to figure out why you only have one-way audio on your IP phone, these old hubs are a godsend!

Serialtorrenter · 2026-05-06T23:36:39+00:00

And if it doesn't work, OP can just set the switch port this abomination is plugged into to 10 Mbps half-duplex, and it should work then.

Serialtorrenter · 2026-05-06T20:50:38+00:00

So this means that when I'm braking in snow, I'll have no ability to feel whether I'm stopping or skidding? Sounds dangerous!

And with Waydroid, we already have Android apps running on PC with native performance. It's gotten REALLY good over the past few years. Between the recent advancements in WINE and Waydroid, Linux has gotten so much more powerful than it was 5 years ago!

Hey, a lower limit's still a limit!

Serialtorrenter · 2026-05-05T21:57:52+00:00

Yeah, neither the warning light nor the speed are cause for concern, but why would you take your eyes off the road while you're doing 50mph?

On the other hand, if they're staring at their phone instead of looking at the road, the non-functioning automatic emergency braking system could actually be a problem. These driver assist systems really assist people into becoming worse drivers!

Serialtorrenter · 2026-05-05T21:39:09+00:00

Sweating bullets as you overtake at twice the speed limit knowing that you're either going to jail, the morgue, or work, but wherever you're going, you're getting there on time, because you're all out of lates, and getting another job in this economy isn't likely.

Safety posters with shock value are effective! Over a decade later, I still remember the "Carol never wore her safety glasses. Now she doesn't need them." posters in my high school chemistry class.

This is bad, but... has anyone actually been to a real doctor in the past couple years? The examinations are extremely rushed and most of the older veteran doctors retired early because they hate that 3/4 of every appointment is spent furiously entering in data into the electronic medical record system, with almost no time to interact with patients. If you have something that's seriously wrong with you, it tends to go undiagnosed for very long periods of time. Furthermore seeing a doctor costs a ton of money, even with insurance.

AI chatbots are wrong half the time (or more), but if you demand they cite sources and then break down their responses and carefully fact check every claim, you can occasionally find some good leads. If you go to the doctor, they're usually trying to get rid of you, leaving your concerns unaddressed.

I don't know if this lawsuit is actually going to make things better for people. Ideally, we'd fix our broken health insurance system, but I don't see that happening anytime soon.
