WireGuard ported to OpenBSD Anonymous 05/25/2018 (Fri) 07:26:39 [Preview] No. 12745 [Reply] [Last 50 Posts]
zx2c4 ported WireGuard to OpenBSD... that's great to have a formally verified VPN software in one of the most secure systems today:

WireGuard is not
>formally verified VPN software

>Y-y-yes it is!
No, it's not. It is experimental software that is based on a formally verified protocol. Protip: TLS is also a formally verified protocol.

In addition:
>WireGuard is not yet complete. You should not rely on this code. It has not undergone proper degrees of security auditing and the protocol is still subject to change. We're working toward a stable 1.0 release, but that time has not yet come. There are experimental snapshots tagged with "0.0.YYYYMMDD", but these should not be considered real releases and they may contain security vulnerabilities (which would not be eligible for CVEs, since this is pre-release snapshot software).

>>12746
>I want muh post quantum algo kernelspace VPN too!
WireGuard is not post-quantum secure by default, and in order to be configured to be, it depends on a pre-shared symmetric key that has to be exchanged out of band. At this point, that means hand-delivering the key.

You're right. Yet, I think it's still better than IPsec and a good improvement over OpenIKED delivered on OpenBSD. It is in development, but I think in the next year it should be more stable and secure. Good keep looking into this, for people doing their own VPN.

Fuck sake, endchan didn't post the images.

Anyway, this is another serious blunder from Intel, after all the exploits that came out from their corner cutting for speed.

Some links:

>We confirmed that Intel was using a water chiller in the 5 GHz demo, a Hailea HC-1000B, which is a 1 HP water chiller good for 1500-4000 liters per hour and uses the R124 refrigerant to reduce the temperature of the water to 4 degrees Celsius. Technically this unit has a cooling power of 1770W, which correlates to the fact that a Corsair AX1600i power unit was being used for the system.

http://archive.today/2018.06.07-022714/https://www.tomshardware.com/news/intel-28-core-processor-5ghz-motherboard,37213.html

>Intel's demo didn't tell the full story. Many in the press mistakenly assumed the new processor runs at 5.0 GHz at stock settings, but we carefully analyzed video from the event and spotted a few obvious signs that the processor was overclocked. Intel was apparently running some sort of closed-loop cooling that required insulating material around the tubing. This turns out to be a water chiller hidden under the table. As expected, all of the components are properly shielded to avoid excess condensation from the chilled liquid.

>The one-horsepower Hailea HC-1000B is a beefy water chiller that can dissipate tremendous amounts of waste heat, but it also requires more than 1,000W for operation. We were originally going to witness the demo first hand, but there wasn't enough power handy to run both the chiller and the system simultaneously

Why is intel not prepared?
They must have a huge R&D advance, from all of this years without any real advance an breakthrough, against an AMD which was nearly none existence.
This demo seems like they took a random card on their desk, plugged some cooling and tapped this together.

That's weird. Maybe intel is in a bad shape, even though that's hard to believe with the money they're making for so much long time. I would like to read more about this.

Intel have been too busy losing their server market due to all the vulnerabilities in their chips because they cut corners to beat AMD in speed. I think Intel has been struggling to keep ahead of AMD for a long while now. This should be a spectacular shit show as they fall down hard in the coming years. I personally can't wait to see what new levels of low they can attain after this.

CPU, RAM, GPU: 1x single board computer

A Single Board Computer provides every component needed to build laptop, except for battery, display, keyboard and case, each of which can be added separately.

Single Board Computers provide CPU, RAM, GPU, motherboard and some other integrated features on a single board. They are full desktop computer system that is sufficiently small and low power consuming to be used as a mobile, DIY laptop. They are also very low cost (<$50).

The most important feature of Single Board Computers is that there are models that are fully open source. It is possible to build a fully functional laptop with Free Software only, including free firmware, wireless and 3D video acceleration drivers. It is even possible to get SBCs with open source hardware designs.

For reference:

Single Board Computers with free 3D video acceleration (Etnaviv)
Nitrogen6X ($225): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC2000, 2 GB DDR3, best option, compatible with mainline kernels
Nitrogen6_MAX ($299): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 4 GB DDR3, faster Nitrogen6X
Wandboard QuadPLUS ($139): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 2 GB DDR3, cheaper version of Nitrogen6_MAX, not mainline

Open source hardware Single Board Computers
BeagleBone Black ($55): Single core ARM A8 @ 1 GHz, TI Sitara AM335x, PowerVR SGX530, 512 MB DDR3, fully open source except GPU, mainline compatible, https://github.com/beagleboard/beaglebone-black

Charger

The DIY Modular Open Source Laptop is designed to be charged by any combination of solar panel, handcrank generator, USB AC adapter, USB car charger, USB port or thermoelectric generator. Unlike most rechargeable electronics, each charger can charge the USB powerbank battery of the DIY laptop seperately from the DIY laptop. This flexible and modular charging ensures the DIY laptop never runs out of energy, yet never needs to be charged either.

For reference
USB solar charger: SOKOO 22W 5V 2-Port USB Portable Foldable Solar Charger ($55)
Handcrank generator: K-TOR Pocket Socket Hand Crank Generator Portable Power Supply 10 Watts 120 Volts ($60)
Pedal generator: K-tor Power Box 20 Watt Pedal Generator ($200)
Thermoelectric generator: Camping Stove Thermoelectric Generator TEG Power - Devil Watt 15 Watt ($304)

Each reference charger can provide the 5V 2A needed to charge a USB powerbank at full speed. The most convenient charger will depend on the situation.

Solar panels can provide >150 W unattended outdoors at daytime.
Handcrank or pedal generators can provide <150 W attended indoors or outdoors, day or night. Handcrank generators can be used while standing or moving, but pedal generators can be used while also using the DIY laptop.
Thermoelectric generators can provide >150 W unattended outdoors, day or night. Indoors with ventilation.
USB AC adapters can be used wherever there is AC electric grid.
USB car adapters can be used with most DC electricity sources such as 12 V car batteries or six 1.5 V AA batteries in series. USB car adapters can also convert DC from solar panels, thermoelectric generators, handcrank generators, DC wind or hydroelectric turbines into 5V DC for charging the DIY laptop.

Very nice. Really.
I think this could be minimized in size, though, using trackpoint ('clit') instead of touchpad and squeezing the components inside. The wood color would also call too much attention while using it in public, so a matte black painting would be nice.
I don't know if you're the creator, but this is pretty cool.

About the keyboard, I had this idea some time ago of using a foldable keyboard from Blackberry, like this one:
https://www.amazon.com/Stowaway-Ultra-Slim-Bluetooth-Blackberry-Handhelds/dp/B0002OKCXE

So, all the components would be together with the display, like a mobile 'tablet', and this foldable keyboard could be unfolded just when you start using the computer and would serve as the 'base' for the display. This could make it less havier and also would be smaller i size.

Never finished that project, but I still think it's a good idea (although I'm thinking about head-mounted displays with hand-adapted keyboard now, instead of conventional laptop format).

This is for those of you who ask about this form factor every so often. I hope enough people join so that he makes beige ones.

The X500 Pro is the final product in a line of computer cases designed a few years back (the X500 Plus and later the Evo with a mechanical keyboard) as a tribute to the computers of the '80s and '90s (Commodore, Atari, Sinclair etc...). It's a wedge styled computer case with built-in, full size mechanical keyboard.

The chassis that I originally opened this thread with is dead so I ended up finding a substitute in the Checkmate A1500 which has the pizza box form factor. It's for Amiga fans but can fit mITX/mATX with a full-size reference blower-style graphics card. There'll also be risers so you can slide your keyboard under it when not in use.

I'm wrong about the use of encryption with the SSD. In fact, you can, but you can't trim the SSD.
So if you're doing heavy work, then it'll be a real problem. I'm not even talking about buying it second hand, and so getting an already used SSD. But you still can use it.

But we have to treat SSDs differently regarding sec.
